Additional Safety Instructions for Nailers
1. HAND INJURIES: Do not place your
hands near the nail point of entry. A
nail can deflect and tear through the
surface of the workpiece, puncturing
your hand or fingers.
6. HOSE USAGE: Make sure your air
hose is designed for the tool in use, is
in good condition, and is long enough
to reach your work without stretching.
However, an overly long air hose in
the work area may be a tripping haz-
ard if not kept out of the way.
7. OPERATING QUESTIONS: If you
are not sure about the intended oper-
ation, stop using the nailer. Seek
formal training.
8. CLEANING: Never use gasoline or
other flammable liquids to clean the
nailer; vapors in the nailer will ignite
by a spark and cause it to explode.
9. MAINTENANCE: Always disconnect
air from the nailer when servicing or
installing nails. During maintenance,
a nailer connected to air may fire acci-
dentally, causing serious personal
injury.
2. COMBUSTIBLE GASES: Never con-
nect the nailer to pressurized oxy-
gen or other combustible gases as a
power source. Only use filtered, lubri-
cated, and regulated compressed air.
3. SAFE HANDLING: Never point the
nailer at others! Do not keep the trig-
ger pulled when loading fasteners,
carrying, or holding tool. Carry the
nailer only by the handle, never by
any other part. Do not carry the nailer
by the air hose. Disconnect the nailer
from the air hose when going up and
down ladders.
4. MODIFICATIONS: DO NOT modify
this tool or bypass the safety nose
mechanism.
5. CHECK VALVE: Do not use a check
valve or any other fitting that allows
air to remain in the tool.

location, such as up ladders, to
another room, or even another job
site. Always disconnect the gun
immediately after use and never
transport the gun while connected to
the air—even if the air compressor is
disconnected from its power source!
Operating this nailer can propel
objects into the air, causing imme-
diate eye damage. To protect your-
self, always wear American National
Standards Institute (ANSI) approved
safety glasses or goggles when oper-
ating this equipment. In addition, this
nailer discharges at up to 85-90 deci-
bels. To protect your hearing, always

Compressed Air
System
The Model T20644 is designed to be oper-
ated at 60-100 PSI using clean, dry, regu-
lated, compressed air. DO NOT exceed
the 120 PSI maximum operating pres-
sure for your model.
Before using your new nailer, regulate the
air pressure to find the optimum setting
within the specified operating range. Start
by testing the nailer at a low setting, then
increase the air pressure as needed for
satisfactory results.
Exceeding the maximum permissible
operating pressure may damage the
nailer and cause it to malfunction. To
reduce your risk of personal injury,
DO NOT allow the air pressure to
exceed the recommended pressure
for this nailer!
An in-line filter/lubricator/regulator unit can
be installed, as depicted in Figure 2.
Check the current Grizzly catalog for avail-
ability of this unit. If you plan on install-
ing a filter/lubricator/regulator unit in your
compressed air system, always follow the
connection instructions that come with
the unit.
This filter/lubricator/regulator unit will
protect your tool from damaging water
build-up, allow you to adjust and maintain
constant air pressure to your tool, and
save you the inconvenience of having to
manually lubricate your tool every time
you use it.

5. Without pressing the trigger, depress
the safety yoke mechanism against a
scrap piece of wood that is clean and
free of any knots, nails, or other foreign
objects.
Safety Yoke
A safety yoke mechanism on the nose
of the nailer acts as a secondary safety
device. When the trigger is pressed, the
nailer will not fire until the safety yoke
mechanism is depressed.
— If the nailer does not fire, then the
safety yoke mechanism is working
correctly.
Before you use your nailer for the first
time, check the safety yoke mechanism to
ensure proper function. To do this:
— If the nailer does fire when you
do this, immediately disconnect the
nailer from the air supply and call
Grizzly Technical Support at (570)
546-9663 for help.
1. DISCONNECT NAILER FROM THE
AIR SUPPLY!
— If the nailer fires when the trigger
is pulled without the safety yoke
mechanism being depressed, then
the nailer is not working properly.
2. Make sure the magazine is empty and
contains no nails.
3. Make sure the trigger and the safety
yoke mechanism move up and down
without sticking.
— If either of these conditions develop
after you have used your nailer for a
period of time, check the lubrication
of these mechanisms.
4. Connect the nailer to the air supply.

Besides damaging your workpiece,
deflection can cause injury if your free
hand is securing the workpiece in the
location that the nail deflects.
Operating
If you have not read the safety instruc-
tions in this manual, do not operate the
nailer.
5. Pull the trigger. If the nail drives into the
wood far enough, continue with your
intended operations. If the nail goes
too far or not far enough, adjust the
depth adjustment knob described in the
Adjusting Depth section.
Before you operate your nailer, place one
drop of the included oil into the quick con-
nect fitting where the nailer connects to
the air supply.
To operate your nailer:
Adjusting Depth
1. Connect the nailer to the air supply.
2. To test for proper nail penetration, hold
the nailer perpendicular to the surface
of a piece of clean scrap wood that is
thick enough for the length of nails you
have loaded.
The Model T20644 features a knurled
adjustment knob (Figure 5) for setting the
nail depth into the workpiece.
Rotate this knob to adjust the workpiece.
To find the correct nail penetration depth,
use trial-and-error on a scrap workpiece of
the same type of material as your work.
3. Depress the safety yoke mechanism on
your workpiece.
4. Before pulling the trigger, make sure
your free hand and other body parts
are positioned out of the way of a
potential path of a nail in case of deflec-
tion.
Deflection is caused when grain irregu-
larities, knots or foreign objects inside
the wood cause the nail to change its
path, resulting in the nail puncturing the
surface of the workpiece, as shown in
Figure 4.

6. Open the magazine.
Replacing Pistons/
O-Rings
7. Watch the discharge area and push the
top of the piston with your finger. You
will see the piston shaft slide down the
discharge area.
Repair pistons are cheap insurance in the
event that a piston or piston shaft becomes
worn out.
8. With a long flathead screwdriver or sim-
ilarly shaped tool, push the piston shaft
back inside the nailer until you can grip
the piston head and remove it from the
cylinder. (Be careful not to scratch the
discharge area when pushing the pis-
ton shaft with the screwdriver.)
The part number for the repair piston for
this nailer is #PT20644098. To order, call
Customer Service at (800) 527-4777.
9. Place a new O-ring on the new piston
and apply a thin film of the nailer lubri-
cating oil on the O-ring.
10. Insert the new piston in the cylinder.
Make sure that the grooves on the pis-
ton shaft line up with those on the guide
at the bottom of the cylinder. The new
piston should easily slide into the cyl-
inder. DO NOT force the piston into
the cylinder! If the piston is not easily
inserted, double-check the alignment of
the piston shaft with the grooves on the
guide.
Always disconnect air from nailer
whenever servicing! During mainte-
nance, a nailer connected to air may
fire accidentally, causing serious
personal injury!
11. After the piston is inserted correctly,
close the magazine. Replace the top
cap assembly and tighten the four cap
screws.
To replace a piston:
1. DISCONNECT NAILER FROM THE
AIR SUPPLY!
12. For more assistance, or to install a
complete O-ring set, refer to Parts
Breakdown on Page 16.
2. Remove all nails from the magazine.
3. Remove the four cap screws on the top
of the nailer, near the exhaust port.
4. Remove the top cap.
5. The top of the piston should now be
visible inside the cylinder, which is
housed in the head of the nailer.

CLEANING & LUBRICATION
Cleaning
Lubricating
Use non-flammable solvent to clean the
nose assembly of the nailer. Always be
sure that the nailer is dry before using it
again.
Standard pneumatic tool oil has been
included with your new Grizzly nailer to
help maintain its useful life. Place two to
six drops of oil in the nailer air inlet (as
shown in Figure 12) before every use, or
after 2 hours of continuous use.
Do not allow dust, chips, sand, etc. into
the air connectors or into the body of the
nailer; this may result in leaks and damage
to the nailer and the air couplings.
Wipe off any excess oil near the nailer
exhaust to avoid dust build-up. When the
oil that was included with the nailer has
been completely used, replace with Grizzly
Model G2820 Pneumatic Tool Oil.
Another option to manual oiling would be
to install a lubricator in your air compres-
sor line. If your air compressor line already
has a lubricator, then regular lubrication
of your nailer will not be necessary. Just
make sure there is always oil in the lubri-
cator.
Never clean this tool with gasoline
or other flammable liquids. Vapors
in the tool may ignite, causing the
tool to explode. Ignoring this warning
may lead to serious personal injury or
even death!
