Milling/Drilling Machines. Accidents are  
frequently caused by lack of familiarity or  
failure to pay attention. Use this tool with  
respect and caution to lessen the possibili-  
ty of operator injury. If normal safety pre-  
cautions are overlooked or ignored serious  
personal injury may occur.  
No list of safety guidelines can be com-  
plete. Every shop environment is different.  
Always consider safety first, as it applies to  
your individual working conditions. Use  
this and other machinery with caution and  
respect. Failure to do so could result in  
serious person injury, damage to equip-  
ment or poor work results.

SECTION 2: CIRCUIT REQUIREMENTS  
110V Operation  
Grounding  
The Model G1006/G1007 is wired for 110V, sin-  
gle phase operation. The 2HP motor will draw 22  
amps at 110V at maximum load. If you operate  
this Mill/Drill on any circuit that is already close to  
its capacity, it may blow a fuse or trip a circuit  
breaker. However, if an unusual load does not  
exist and a power failure still occurs, contact a  
qualified electrician or our service department.  
In the event of an electrical short, grounding  
reduces the risk of electric shock by providing a  
path of least resistance to disperse electric cur-  
rent. This tool is equipped with a power cord hav-  
ing an equipment-grounding conductor. See  
Figure 1. The outlet must be properly installed  
and grounded in accordance with all local codes  
and ordinances.  
Circuit Load/Reset  
This equipment must be grounded. Verify  
that any existing electrical outlet and circuit  
you intend to plug into is actually ground-  
ed. If it is not, it will be necessary to run a  
separate 12 A.W.G. copper grounding wire  
from the outlet to a known ground. Under  
no circumstances should the grounding pin  
from any three-pronged plug be removed.  
Serious injury may occur.  
The Model G1006/G1007 can be fused at 20  
amps. If the circuit breakers trip frequently, and  
you have determined you are on a dedicated cir-  
cuit with no other loads, it may be necessary to  
upgrade to a 25 amp circuit. Contact a qualified  
electrician to specifically determine the needs for  
your shop.  
You will find that the motor supplied with the  
Mill/Drill is equipped with a reset button. If during  
operation the reset button disengages power  
from the motor, allow it to cool for five minutes.  
Depress the button. It should stay down and the  
motor should start by pressing the start switch. If  
the reset button continues to deactivate the motor  
or if it will not reset, call the Service Department.  
Extension Cords  
If you find it necessary to use an extension cord  
with the Model G1006/G1007, make sure the  
cord is rated Hard Service (grade S) or better.  
Refer to the chart in Section 1: Safety  
Instructions to determine the minimum gauge  
for the extension cord. The extension cord must  
also contain a ground wire and plug pin. Always  
repair or replace extension cords when they  
become worn or damaged.  
Figure 1. Grounded plug configuration.

G1006/G1007 Mill/Drill  
 
220V Operation  
Grounding  
The Model G1006/G1007 can be wired for 220V  
single phase operation (see Wiring Diagram,  
page 23). The motor will safely draw about 11  
amps at 220V under load. If you operate the  
Mill/Drill on any circuit that is already close to its  
capacity, it might blow a fuse or trip a circuit  
breaker. However, if an unusual load does not  
exist, and power failure still occurs, have the cir-  
cuit inspected by a qualified electrician.  
In the event of a malfunction or breakdown,  
grounding provides a path of least resistance for  
electric current to reduce the risk of electric  
shock. This tool is equipped with an electric cord  
having an equipment-grounding conductor which  
must be properly connected to a grounding plug.  
The plug must be plugged into a matching outlet  
that is properly installed and grounded in accor-  
dance with all local codes and ordinances.  
Circuit Load/Reset  
This equipment must be grounded. Verify  
that any existing electrical outlet and circuit  
you intend to plug into is actually ground-  
ed. If it is not, it will be necessary to run a  
separate 12 A.W.G. copper grounding wire  
from the outlet to a known ground. Under  
no circumstances should the grounding  
wire be left unconnected when installing  
the 220V plug. Serious injury may occur.  
The Model G1006/G1007 should be fused at 15  
amps. Fusing at amperage ratings higher than 15  
amps will not adequately protect the circuit. You  
will find that the motor supplied with the Mill/Drill  
is equipped with a reset button. If during opera-  
tion the reset button disengages power from the  
motor allow it to cool for five minutes. Depress  
the button. It should stay down and the motor  
should start by pressing the start switch. If the  
reset button continues to deactivate the motor or  
if it will not reset call the Service Department.  
Extension Cords  
We do not recommend the use of extension  
cords on 220V equipment. It is much better to  
arrange the placement of your equipment and  
the installed wiring to eliminate the need for  
extension cords. Should it be necessary to use  
an extension make sure the cord is rated Hard  
Service (grade S) or better. Refer to the chart in  
Section 1: Safety Instructions to determine the  
minimum gauge for the extension cord. The  
extension cord must also contain a ground wire  
and plug pin. Always repair or replace extension  
cords when they become worn or damaged.  
In preparing to connect the Model G1006/G1007  
to your existing or new circuit, it will be necessary  
to connect a plug that matches your 220V recep-  
tacle. If you will be installing a new receptacle  
and plug, we recommend either of the styles  
shown in Figure 2. Note that you have the choice  
between simple plug-in and twist-lock plug styles.  
Whichever style you choose, be sure that both  
the plug and outlet are rated at 15 amps or bet-  
ter.  
Standard  
Locking  
The electrical requirements presented here  
are are not necessarily comprehensive.  
You must be sure that your particular elec-  
trical configuration complies with local and  
state codes. Ensure compliance by check-  
ing with your local municipality or a  
licensed electrician.

Unpacking  
Piece Inventory  
Most of the G1006/G1007 has been pre-assem-  
bled at the factory. Therefore, there are very few  
loose parts.  
This Milling/Drilling Machine is shipped from the  
manufacturer in a carefully packed crate. If you  
discover the machine is damaged after you’ve  
signed for delivery, and the truck and driver are  
gone, you will need to file a freight claim with the  
carrier. Save the containers and all packing mate-  
rials for possible inspection by the carrier or its  
agent. Without the packing materials, filing a  
freight claim can be difficult. If you need assis-  
tance determining whether you need to file a  
freight claim, or with the procedure to file one,  
please contact our Customer Service.

Clean Up  
Site Considerations  
The unpainted surfaces are coated with a waxy  
oil to protect it from corrosion during shipment.  
Remove this protective coating with a solvent  
cleaner or citrus-based degreaser. Avoid chlo-  
rine-based solvents as they may damage painted  
surfaces they may contact. Always follow the  
usage instructions on the product you choose for  
clean up.  
FLOOR LOAD  
Your G1006/G1007 Milling/Drilling Machine rep-  
resents a large weight load in a small footprint. If  
you question the strength of your workbench, you  
can opt to reinforce it, or consider placing the  
Mill/Drill on a freestanding bench like Grizzly’s  
G5944 Stand for Mill/Drills.  
WORKING CLEARANCES  
Working clearances can be thought of as the dis-  
tances between machines and obstacles that  
allow safe operation of every machine without  
limitation. Consider existing and anticipated  
machine needs, size of material to be processed  
through each machine, and space for auxiliary  
stands and/or work tables. Also consider the rel-  
ative position of each machine to one another for  
efficient material handling. Be sure to allow your-  
self sufficient room to safely run your machines in  
any foreseeable operation.  
Many of the solvents commonly used to  
clean machinery can be highly flammable,  
and toxic when inhaled or ingested. Always  
work in well-ventilated areas far from  
potential ignition sources when dealing  
with solvents. Use care when disposing of  
waste rags and towels to be sure they do  
not create fire or environmental hazards.  
Keep children and animals safely away  
when cleaning and assembling this  
machine.  
LIGHTING AND OUTLETS  
Lighting should be bright enough to eliminate  
shadow and prevent eye strain. Electrical circuits  
should be dedicated or large enough to handle  
combined motor amp loads. Outlets should be  
located near each machine so power or exten-  
sion cords are not obstructing high-traffic areas.  
Be sure to observe local electrical codes for prop-  
er installation of new lighting, outlets, or circuits.  
Do not use gasoline or other petroleum-  
based solvents to remove this protective  
coating. These products generally have low  
flash points which makes them extremely  
flammable. A risk of explosion and burning  
exists if these products are used. Serious  
personal injury may occur.  
NOTICE  
Make your shop “child safe”. Ensure that  
your workplace is inaccessible to young-  
sters by closing and locking all entrances  
when you are away. Never allow visitors in  
your shop when assembling, adjusting or  
operating equipment.  
Make sure that all of the protective coating  
is removed from the dovetail ways and col-  
umn before operating the table or  
lifting/lowering the head.

G1006/G1007 Mill/Drill  
 
SECTION 4: ASSEMBLY  
Beginning Assembly Drilling Angle Vise  
Most of your G1006/G1007 has been assembled  
at the factory, but some parts must be assembled  
or installed after delivery. We have organized the  
assembly process into steps. Please follow along  
in the order presented here.  
The drilling angle vise provided with your Mill/Drill  
attaches to the table with a table clamping kit.  
Table clamping kits are available through the  
Grizzly Catalog and must be purchased sepa-  
rately. This table will accept 1/2" bolt clamping kits  
(G1076).  
TOOLS REQUIRED: You will need a 10mm,  
12mm, 14mm and 19mm open end wrenches,  
and a 2.5mm, 3mm, 4mm and 5mm Allen®  
wrench.  
You can mount the drilling angle vise almost any-  
where on the table, and it provides a myriad of  
uses when drilling.  
All die-cut metal parts have a sharp edge  
(called “flashing”) on them after they are  
formed. This is generally removed at the  
factory. Sometimes a bit of flashing might  
escape inspection and the sharp edge may  
cause cuts or lacerations when handled.  
Please examine the edges of all die-cut  
metal parts and file or sand the edge to  
remove the flashing before handling.  
Do not use the angle vise for milling. It is  
made strictly for holding materials to be  
drilled. This vise will not adequately  
clamp an object safely for a milling oper-  
ation. There is not enough clamping pres-  
sure available and objects may be pulled  
out or upset in the vise jaws causing cut-  
ting tools to break and/or parts to be  
thrown. Any attempt to perform a milling  
operation using this vise may result in  
personal injury.  
Mounting  
It is recommended that you cut a hole in your  
stand top to allow access to the under side of the  
base on the Mill/Drill. This will be necessary for  
adjusting the Y-plane leadscrew.  
DO NOT make adjustments while the  
Mill/Drill is running. Ensure that the switch  
is off, power is disconnected and moving  
parts have stopped before making adjust-  
ments.  
Before attempting to use your Mill/Drill, mount it  
securely to your benchtop or stand. Use the  
largest bolts possible to secure it to the benchtop.  
With the head fully raised, this unit is very  
top heavy and will tip over if not bolted  
down. Tipping can cause a pinch or crush-  
ing type injury. Secure the base firmly.

4. Plug the rapid switch cord into the recepta-  
cle provided on the bottom of the power  
feed body.  
Power feed  
5. Screw the knob onto the direction handle.  
The Model G1007 features a 110V auto-feed  
mechanism which allows hands-free, side-to-side  
passes while milling. Variable-speed feed control  
makes flat surface milling more consistent.  
6. Place the clear plastic gear cover to the  
bottom of the power feed to protect the  
gears.  
To install the power feed:  
7. Insert the stops into the slot on the front  
edge of the table. Tighten them with a 5mm  
Allen® wrench.  
1. Attach the 21/4" diameter drive gear to the  
left end of the longitudinal table leadscrew.  
The setscrew for securing the drive gear  
requires a 2.5mm Allen® wrench. The gear  
couplers on the drive gear and table lead-  
screw will lock together.  
NOTICE  
Before using the G1007, place the power  
feeder cord and the control cord for the  
microswitch clear of any movements which  
could pinch or crush them. Before using  
the power feed, mark the maximum dis-  
tance the table can move before the power  
feed comes in contact with the machine’s  
base. Use that mark as a reference each  
time you re-adjust your table stops. This is  
the best way to avoid damaging the power  
feed and/or causing an unsafe condition.  
2. Set the clamping bracket assembly on the  
left end of the table. Mark the points on the  
table’s trough where the mounting bolts  
contact the table. Remove the clamping  
bracket assembly and spot drill to give the  
mounting bolts a small lip to “bite” without  
slipping on the rough cast surface. Set the  
clamping bracket assembly back on the  
end of the table and tighten down the  
mounting bolts.  
3. Use a 5mm Allen® wrench to attach the  
power feed body to the clamping bracket  
assembly. Cap screws are provided.  
Before tightening completely, position the  
power feed body so the gears mesh per-  
fectly. Tighten the cap screws when the  
gears are in mesh.  
8. Remove the center travel stop at the front  
of the table. Save the mounting bolts.  
9. Secure the switch bracket to the front of the  
Mill/Drill. Use the mounting bolts saved in  
step 8.  
10. Mount the switch to the switch bracket  
using the cap screws provided. Tighten  
them with a 6mm Allen® wrench. When the  
switch is depressed, the power feed auto-  
matically turns off and table movement  
stops.  
NOTICE  
Use care when aligning the table lead-  
screw gears with the gearing on the power  
feed. The fit is correct when you can just  
slightly wiggle one gear without engaging  
the other. If there is too much space  
between the gears, teeth can be stripped  
under heavy loads. If the teeth mesh too  
tightly, the supporting bearings in the  
power feeder will wear out quickly.

G1006/G1007 Mill/Drill  
 
Collet/Arbor  
Handwheels/Crank  
There are three handwheels provided with the  
machine which control table movement. They are  
secured with setscrews and mounted as follows.  
Height adjustment is made using the crank pro-  
vided.  
The Models G1006/G1007 feature an R-8 spindle  
which accepts many industrial collets and arbors.  
To install a collet or an arbor:  
1. Release the latches on the head cover and  
Each handwheel has a setscrew which tightens  
with a 3mm Allen® wrench. The handwheel han-  
dles screw into the threaded holes on each hand-  
wheel. Turn the nut on the handwheel handles  
until almost tight against the plastic handle.  
Screw into the handwheel and tighten the nut  
against the wheel while maintaining the screw’s  
position with a screwdriver. This nut acts as a  
locknut and a spacer.  
open it.  
2. Insert the collet or cutting tool’s arbor up  
into the spindle housing. Rotate the collet  
or arbor to line up the keyway with the  
matching pin in the spindle opening.  
3. Turn the hex head at the top of the drawbar  
(located on the top, front of the head) clock-  
wise until the threads at the bottom of the  
drawbar mesh with the female threads in  
the top of the collet or arbor.  
The first two handwheels mount on the ends of  
the table and move the table left and right. With  
the power feed installed on the G1007, there is  
only one side handwheel installation location.  
Save the extra handwheel in case the power feed  
cannot be used.  
4. Insert the cutter in the hole at the bottom of  
the collet and continue to tighten the draw-  
bar until both the collet and cutter are tight-  
ly in place. Do not over-tighten the collet.  
Grasp the V-Belt that goes around the  
front pulley. Pull gently while tightening.  
The third handwheel mounts in front of the base  
and moves the table toward and away from the  
front of the machine.  
To remove a collet or an arbor:  
The head crank secures to the left side of the  
machine. Screw its handle into the threaded hole  
at the end of the crank. This handle is similar to  
those in the handwheels. Use a 5mm Allen®  
wrench to tighten the setscrew that secures the  
hand crank to its shaft.  
1. Loosen the hex head at the top of the draw-  
bar (2 or 3 turns).  
2. Hold the cutter with a shop towel to pre-  
vent it from dropping completely out of  
the machine. Tap on the top of the draw-  
bar with a rubber mallet to loosen the collet  
from the spindle.  
Screw a black knob onto an end of each of the  
three chrome feed levers. These are the levers  
that control the up and down movement of the  
spindle. Screw the levers with knobs into the  
threaded holes on the hub, located on the right  
side of the machine.  
3. Continue to turn the drawbar counterclock-  
wise until it is free from the collet. Once  
loose, remove and replace with your  
desired collet. Remove cutting tools from  
spindle when not in use.

Drill Chuck/Arbor  
All types of milling cutters and drill bits are  
sharp. It is recommended that these not be  
handled directly. Use paper towels to hold  
sharp tooling to avoid cuts to your hands.  
Be careful while handling them and store  
them in a child safe location.  
Your Mill/Drill has been pre-fitted with a drill  
chuck arbor that has an R-8 shank and a Jacob’s  
Taper. It is ready to accept the standard drill  
chuck provided with this machine.  
To install the drill chuck:  
Fly Cutter/Arbor  
1. Clean the grease off the drill chuck. Pay  
particular attention to the bore in the drill  
chuck: it must be free from all grease, oil  
and debris.  
Your Mill/Drill comes equipped with a fly cutter  
that fits on the 1" stub end of the R-8 arbor.  
2. Clean any grease, oil or debris off the  
Jacob’s Taper already installed in your  
Mill/Drill.

SECTION 5: ADJUSTMENTS  
the handwheel dial. Turn the dial until the  
“0” lines up with the index line. Tighten the  
setscrew.  
Graduated Dials  
The graduated dials on the handwheels for the  
table and fine feed can be indexed or “zeroed” to  
help make accurate and convenient movements.  
Each dial can be reset or locked with the set-  
screw or thumbscrew provided.  
4. Turn the handwheel according to the dis-  
tance you want to move downward. Each  
complete revolution equals 0.100".  
Locking:  
For milling operations, the spindle height can  
be locked in by tightening the lever on the for-  
ward, left hand portion of the head.  
Example:  
Suppose you want to drill a series of holes in a  
workpiece at 0.625" centers. After locating the  
first hole’s placement and drilling, you can set  
the dial of the appropriate axis to zero while  
holding the handwheel. Move the table 0.625".  
Drill the next hole and proceed as above.  
Depth Stop  
The depth stop is used to control the range of  
downward movement by the drill bit or cutter.  
Maximum depth is 5".  
Spindle Height  
To calibrate the depth stop:  
You have two options for spindle height adjust-  
ment - a drill press style, levered downfeed and a  
micro adjustment handwheel. The three levers  
are located on the right, forward portion of the  
head. The micro adjustment handwheel is on the  
front right hand side of the head.  
1. Make sure the spindle is drawn all the way  
up into the head. Place a piece of paper on  
the workpiece. Loosen the headstock bolts  
and lower the head until the drill bit or cut-  
ter just contacts the paper. Tighten the  
headstock bolts.  
To operate the feed lever:  
2. Turn the depth stop leadscrew until the top  
of the indicator plate is level with your  
desired depth as listed on the scale to the  
left or right. The depth stop leadscrew is  
controlled by the knurled knob under the  
front of the headstock.  
There are 3 levers with knobs located on the right  
side of the headstock. Pull the lever nearest you.  
The spindle will go down until you stop pulling or  
until it hits the depth stop.  
To operate the micro-adjustment handwheel:  
3. Begin drilling or milling. Note for precision  
1. Tighten the locking knob located on the  
depth: set the depth stop shallow of the

desired depth by 16''. Drill the hole and  
measure. Finish to depth using the fine  
downfeed handwheel with its graduated  
dial and use the procedure laid out in  
Graduated Dials above.  
2. Locking out the levered downfeed will  
transfer control to the handwheel. The  
handwheel will not function if the locking  
knob is loose.  
3. Loosen the setscrew on the rim surface of

Head Height  
Speed Changes  
The G1006/G1007 is capable of twelve different  
speed settings. Different types of cuts and types  
of materials require varying speeds. Consult out-  
side sources for information about appropriate  
speeds for different applications.  
The head height on this Mill/Drill can be adjusted  
for various applications.  
To adjust the head height:  
1. Loosen the two head locking nuts located  
on the right side of the head near the back.  
Use the lug wrench provided.  
To change speeds:  
1. Loosen the motor locking lever. It is located  
on the right side of the machine, near the  
back. Pull the motor inward to move the  
rear pulley toward the spindle.  
2. Use the head crank to move the head up or  
down according to your needs.  
3. Tighten the two head locking nuts.  
2. Loosen the two bolts that hold the center  
pulley system in place, so the pulley will  
float.  
3. With the center and rear pulleys loose,  
move the V-Belts to the position on the pul-  
leys corresponding to the desired speed  
(See chart below).  
4. Push the motor back to tighten the rear V-  
Belt and tighten the motor locking lever.  
5. Tighten the bolts holding the center pulley  
in place.

Power feed  
pushed in the direction of desired move-  
ment to move the table at maximum veloc-  
ity.  
The power feed will move the table in the X-plane  
only.  
8. If there is a powerfeed motor overload (i.e.  
trying to move too fast through a heavy  
cut), the built in circuit breaker will trip, and  
the powerfeed will stop. If this occurs, pro-  
ceed with these steps:  
To operate the power feed:  
1. Loosen the table locking levers located just

below the front edge of the table.  
b.Turn the powerfeed switch to the “off”  
2. Adjust the table stops to the right and left to  
the desired distance you wish the table to  
travel. When they hit the switch the power  
feed will be deactivated.  
position.  
c.Press the circuit breaker reset button  
located in the upper left front corner  
of the power feed unit.  
d.Troubleshoot and remedy the cause  
of the electrical overload and start  
again.  
Before running your power feed be sure  
there is enough running clearance between  
the table, spindle, vise, clamps and/or  
parts. Be aware that all of these can  
become pinch points.  
Table Movement  
3. Use the switch located to the left of the  
power feed lever to turn on the power feed.  
Movement:  
4. Push the lever to the right to move the  
table to the right.  
The Mill/Drill table can be moved in the X-Y plane  
only. The handwheel(s) on the side(s) of the table  
move the table either left or right. The handwheel  
in the front of the table will move the table back  
and forth.  
5. Push the lever to the left to move the table  
to the left.  
6. Turn the dial at the base of the lever to  
increase or decrease the speed of table  
movement.  
One complete revolution of either handwheel  
moves the table 0.100".  
Locking:  
NOTICE  
The table can be locked in either direction. Y-  
plane movement is stopped by locking the two  
lever-screws located just below the front middle  
of the table. The X-plane movement is stopped  
by locking the two butterfly screws located under  
the table on the right side of the base.  
The table stops supplied with the machine  
will not stop the powerfeed until the switch  
buttons are totally depressed. To set up for  
accurate stops make a few “dry runs” with-  
out running the Mill/Drill. Reset the stops  
until the table motion ends in a satisfactory  
location.

Notes  
Test Run  
Operating this equipment has the potential  
to propel debris into the air which can  
cause eye injury. Always wear safety glass-  
es or goggles when operating equipment.  
Everyday glasses or reading glasses only  
have impact resistant lenses, they are not  
safety glasses. Be certain the safety glass-  
es you wear meet the appropriate stan-  
dards of the American National Standards  
Institute (ANSI).  
Once assembly is complete and adjustments are  
done to your satisfaction, you are ready to test  
run the machine.  
Turn on the power supply at the main panel.  
Press the START button. Make sure that your fin-  
ger is poised on the STOP button, just in case  
there’s a problem. The Mill/Drill should run  
smoothly, with little or no vibration or rubbing  
noises. Strange or unnatural noises should be  
investigated and corrected before operating the  
machine further.  
DO NOT make adjustments while the  
Mill/Drill is running. Ensure that the switch  
is off, power is disconnected and moving  
parts have stopped before making adjust-  
ments.  
If you cannot easily locate the source of an  
unusual noise or vibration, contact our Service  
Department for help. (See Introduction)

SECTION 7: MAINTENANCE  
General  
Gibs  
Your Model G1006/G1007 Mill/Drill requires very  
little maintenance. A thorough cleaning, now and  
again, will increase the machine’s durability and  
efficiency by removing chips and grime that can  
gum up moving parts. It is best of course, to do  
this after each use.  
The gibs are pre-adjusted at the factory and  
will not need further adjustment by you until  
after extended use. If movement seems too  
tight at first, make sure that all rust preventa-  
tive is removed from the ways, lubricate them  
with oil, and work the table back and forth  
several times to loosen it up.  
Sharp cutters are essential for top performance. If  
you find that the machine cuts less efficiently than  
usual, inspect the cutters and sharpen or replace  
them as necessary.  
The gibs are adjusted by turning the large slotted  
screwheads in the front and right side of the table  
base until you feel a slight drag when you turn the  
handwheels. The screw at the front of the  
machine affects movement from front to back.  
The screw under the right side of the table affects  
longitudinal movement. You can loosen the  
screws if your table movement seems excessive-  
ly stiff.  
An occasional application of a protective spray  
coating will keep the table and other bare metal  
parts from rusting and pitting.  
DO NOT make adjustments while the  
Mill/Drill is running. Ensure that the switch  
is off, power is disconnected and moving  
parts have stopped before making adjust-  
ments.  
-19-  
G1006/G1007 Mill/Drill  
 
Lubrication  
Quill  
The internal quill pin is a setscrew and has  
been pre-adjusted at the factory. It should not  
need adjustment under normal circum-  
stances.  
DO NOT make adjustments while the  
Mill/Drill is running. Ensure that the switch  
is off, power is disconnected and moving  
parts have stopped before making adjust-  
ments.  
The slotted setscrew on the left side of the head  
is used for limiting the amount of rotational play  
in the quill body. Loosening the check-nut and  
tightening the setscrew will work to eliminate this  
play in the quill.  
Points requiring periodic lubrication are:  
1. The main column. A light film of oil will  
smooth action and prevent rust and corro-  
sion.  
If you are worried that you might have exces-  
sive quill play, spindle looseness or if an acci-  
dent has occurred that requires this  
setscrew’s readjustment, contact the Service  
Department for advice.  
2. The quill. A light coating of oil will ensure  
smooth movement.  
3. The quill return spring. Oil annually with a  
light lubricant (SAE 20). Apply with a brush  
or squirt can.  
V-Belts  
4. The quill pinion. Lubricate every 90 days  
with non-hardening grease.  
Inspect regularly for tension and wear. Replace  
when necessary with a size B-42 belt for the spin-  
dle pulley to the idler pulley belt and a size B-34  
belt from the idler pulley to the motor pulley belt.  
Check pulleys to ensure that they are properly  
aligned.  
5. The table leadscrews. Lubricate once each  
week with several drops of SAE 20.  
6. The table leadscrew bearings. Lubricate  
the bearings located at the ends of the table  
and just in front of the Y axis hand crank on  
a daily basis. You will find oil ports with a  
ball. Apply a small amount of SAE 20 using  
the oil can’s tip to push in the ball.  
7. The table and apron slides. Lubricate the  
table slides daily. An oil port with a ball is  
located on the operators side of the table  
edge. The apron slide can be oiled directly.  
Make sure to carefully clean chips and dirt  
off of this slide before oiling.

Table Leadscrews  
Return Spring Tension  
When you turn the handwheels to adjust the posi-  
tion of the table, you will notice slight play in the  
handwheel before the table begins to move. If  
this play exceeds 0.010" (measured with the dial  
at the base of each handwheel), then you will  
need to adjust the leadscrews.  
The spring’s tail is located on the perimeter  
of the spring housing. This part may be  
sharp! Use leather gloves or a heavy shop  
towel to cover the tail while loading or  
unloading return spring pressure. Failure  
to use such precautions will results in per-  
sonal injury.  
To adjust the Y-plane leadscrew:  
1. Access the underside of the base through  
the hole in the bench under the base.  
The spring tension for automatic quill recoil  
has been pre-set at the factory. It should not  
need adjustment under most normal circum-  
stances. If it does need adjustment, the spring  
housing is located on the left side of the head.  
2. Locate the adjuster midway along the lead-  
screw, inside the base.  
3. Tighten the Allen® head setscrew on the  
adjuster.  
To adjust the spring tension:  
4. Test the adjustment by turning the front  
handwheel. You should detect less than  
0.010" of play.  
1. Loosen black thumb knob, located in the  
center of the spring housing, by only two or  
three turns.  
To adjust the X-plane leadscrew:  
1. Locate the longitudinal leadscrew adjuster  
under the middle of the table. The Allen®  
head on the adjustment screw faces to the  
right.  
Do not completely remove the cover! If you  
remove the spring cover, the spring will  
uncoil rapidly, probably cause injury, and  
be nearly impossible to put back together.  
2. Tighten the adjustment screw with a long  
Allen® wrench.  
2. Pull the spring cover out a little bit so the  
notches just clear the roll pin. Hold the  
spring cover tightly or the force of the  
spring will make it spin out of control.  
3. Test the adjustment by turning one of the  
side handwheels. You should detect less  
than 0.010" of play.  
These adjusters may require you to fabricate  
extensions for your hex wrenches. Make adjust-  
ments in small increments. Over-tightening can  
add unnecessary wear to both the leadscrews  
and the adjusters.  
3. Rotate the cover to adjust the tension.  
Push the cover back in to engage the roll  
pin in one of the notches.  
4. Tighten the black thumb knob.
