DOUBLE INSULATION SYSTEM ENHANCES SAFE OPERATION
DOUBLE INSULATION
To enhance safe operation of this electric power tool, JOHN DEERE has adopted a
double insulation system. The term "double insulation" used here denotes an insulation
systems with two insulations physically separated and arranged between the electrically
conductive material connected to the power supply and outer frame subject to contact by
the operator.
Thus, the power tool is termed double insulated and both the mark and "
insulation", or either one is indicated on the name plate.
" double
While no external grounding is required with this system, normal safety precautions as
outlined in this manual must still be followed.
To maintain the effectiveness of the double insulation system, follow the precautions
described below:
1. Always contact your John Deere Dealer when assembling, disassembling or
replacing parts other than accessories or carbon brushes. Improper assembly
and/or replacement with wrong parts may result in eliminating the double
insulation-feature.
2. Clean the exterior of the tool with a soft cloth moistened with soapy water, and
dry thoroughly. Choleric solvent, gasoline, and thinner will cause plastic compo
nents to dissolve.

Operation
APPLICATIONS:
Cutting various types of wood.
PRE-OPERATION:
Before using the Electric Power Tool, complete the following
preparations:
1. Power source:
Ensure that the power source to be utilized conforms to
the power requirements specified on the product
nameplate.
2. Power switch:
Ensure that the power switch is in the "OFF" position. If
the plug is connected to a power receptacle while the
power switch is in the ON position, the power tool will
start operating immediately, inviting serious accident.
3. Extension cord:
(Fig. 4)
When the work area is removed from the power source,
use an extension cord of sufficient thickness and rated
capacity. The extension cord should be kept as short as
practicable.
4. Prepare a wooden work bench (Fig. 4):
Since the saw blade will extend beyond the lower surface
of the lumber, place the lumber on a work bench when
cutting. If a square block is utilized as a work bench,
select level ground to ensure it is properly stabilized. An
unstable work bench will result in hazardous operation.
(Fig. 5)
CAUTION:
TO AVOID POSSIBLE ACCIDENT,
ALWAYS ENSURE THAT THE PORTION
OF LUMBER REMAINING AFTER
CUTTING IS SECURELY ANCHORED
OR HELD IN POSITION.
5. Confirm the power receptacle:
If the power receptacle only loosely accepts the plug, the
receptacle must be repaired. Contact the nearest electric
store for repair service. If such a faulty receptacle is
used, it may cause overheating, resulting in a serious
hazard.
(Fig. 6)
ADJUSTING THE SAW PRIOR TO USE:
1. Adjusting the cutting depth (Fig. 5, Fig. 6):
To adjust cutting depth, loosen the clamp lever and, while
holding the base with one hand, move the main unit up
and down to obtain the prescribed cutting depth. Inch
scale on the saw cover and metric scale on the link
provide a general guide to cutting depth. After adjusting
to the prescribed cutting depth, tighten the clamp lever
securely.
2. Adjusting the angle on inclination:
As shown in Fig. 7 by loosening the wing-bolt on the
inclined gauge, the saw blade may be inclined to
maximum angle of 45 in relation to the base. Always
insure that the wing-bolt is thoroughly tightened after
making the desired adjustment.
(Fig. 7)

GRIP THE SAW AS SHOWN IN FIG. 2
AND BE SURE THE CORD IS FREE TO
MOVE THROUGH THE ENTIRE CUT
WITHOUT JAMMING OR GETTING IN
THE PATH OF THE SAW BLADE.
(Fig. 8)
1. Place the saw body (base) on the lumber, and as in Fig.
8 align the intended line of cut with the saw blade, using
the notch at the front of the base. This relationship of
base to lumber should remain unchanged regardless of
the inclination of the base.
2. The switch should be turned to the ON position before
the saw blade comes into contact with the lumber. The
switch is turned ON when the trigger is pulled by one's
finger, and is turned OFF when the trigger is released.
3. Moving the saw straight at a constant speed will produce
optimum cutting.
CAUTIONS:
BEFORE STARTING TO SAW, ENSURE THAT THE SAW
BLADE HAS REACHED FULL SPEED REVOLUTION.
SHOULD THE SAW BLADE STOP OR MAKE AN
ABNORMAL NOISE DURING OPERATION, TURN OFF
THE SWITCH IMMEDIATELY.
DURING OPERATION, DO NOT COVER THE SLOTS IN
THE TAIL TO PREVENT MOTOR BURN.
ALWAYS TAKE CARE IN PREVENTING THE POWER
CORD FROM COMING NEAR THE REVOLVING SAW
BLADE.
WHEN FINISHED WITH A JOB, PULL OUT THE PLUG
FROM THE POWER RECEPTACLE.

Maintenance and Inspection
MAINTENANCE AND INSPECTION:
CAUTION:
BE SURE TO SWITCH POWER OFF AND DISCONNECT THE
PLUG DURING MAINTENANCE AND INSPECTION.
1. Inspecting the saw blade: Since use of a dull saw blade will degrade efficiency and
cause possible motor malfunction, sharpen or replace the saw blade as soon as
abrasion is noted.
2. Inspecting the mounting screws: Regularly inspect all mounting screws and ensure
that they are properly tightened. Should any of the screws be loose, retighten them
immediately. Failure to do so could result in serious hazard.
3. Inspecting the carbon brushes: The motor employs carbon brushes which are
consumable parts. Since an excessively worn carbon brush could result in motor
trouble, replace the carbon brush with a new one which has the same carbon brush
No. shown in figure when it becomes worn to or near the "wear limit". In addition,
always keep carbon brushes clean and ensure that they slide freely within the
brush holders.
4. Replacing a carbon brush: Disassemble the brush cap with a minus head
screwdriver. The carbon brush can then be easily removed.
5. Adjusting the base and saw blade to maintain perpendicularity: The angle between
the base and the saw blade has been adjusted to 90, however should this
perpendicularity be lost for some reason, adjust in the following manner.
a. Turn the base face up (Fig. 13) and loosen the wing bolt (A) (Fig. 7).
b. Apply a square to the base and the saw blade and, turning the slotted set
screw with a minus screwdriver, shift the position of the base to produce the
desired right angle.
