IV. UNPACKING
V. AIR
Carefully remove the items packed in the car-
ton. It may be a good idea to save the carton
and packing material in case it might be need-
ed in the future. Upon removal of all items
from the package, you should have:
A. AIR PRESSURE
Air pressure should be set at the minimum
required to set the fastener and must not
exceed 120 p.s.i. Follow all safety items
above and see Section V.B. Consistently
operating at unnecessarily high pressures will
put excessive stress on internal parts which
will lead to premature gun failure.
1. Nail Gun
2. Allen Head Wrench
3. Oil Bottle
4. Safety Goggles
B. AIR QUALITY
This air gun must be regularly oiled and oper-
ated with treated or clean air. It is a precision
tool with close internal tolerances designed for
repetitious use. Wet and dirty air will negative-
ly affect the gun’s performance as well as pre-
maturely destroy internal parts.
Trigger
To ensure that the best quality air enters
your nail gun:
1. Use an in-line system to automatically oil,
filter, and dry compressed air. Grizzly
offers an in-line regulator / filter / water-
separator / lubricator (G2304). Please
refer to our catalog for price and ordering
information.
Magazine
Safety nose
Figure 1 shows the front side of the nail gun.
2. The intake air filter on your compressor
must be clean and operational.
Periodically clean or replace this filter. It
is your primary line of defense.
Air Nozzle
3. Drain the compressor air storage tank(s)
often. If conditions are humid, drain up to
several times daily. Water vapor will con-
dense and accumulate in the bottom of
the storage tank(s). The internal metal
parts of the nail gun will be corroded by
the moisture that is passed through the
air supply hose.
4. Keep air hoses as clean as possible inter-
nally. Inspect nipples and couplers for
any dirt and moisture. Blow out prior to
connecting the gun.

VI. PRE-USE CHECKS
VII. OPERATIONS
A. CLEANING
A. LOADING FASTENERS
Keep the gun nose as clean as possible. Dirt
and debris have a tendency to work their way
into the gun from the nose. Wipe off any dirt
that collects on the outside of the gun before
connecting it to the air supply.
To load the gun:
1. Disconnect the air hose if connected.
2. Slide the nails into the magazine through
the rear slot. Figure 3.
B. OILING
3. Pull the spring handle back behind the
last nail and let it go slowly. It will press
against the nails. Figure 4.
Keep the gun oiled. Use special pneumatic
tool oil to keep internal parts well lubricated.
This tool oil is available through the Grizzly
Catalog (G2820).
If your air supply is not pre-lubricated, you
must add 2 drops of oil directly into the air
nozzle at the rear of the gun each time the
magazine is loaded. NEVER USE any oil that
will corrode the rubber O-ring seals such as
detergent oils or oils that are used as sol-
vents. Avoid over-oiling.
With these points in mind, you can operate
your nail gun under the best possible condi-
tions for increased dependability and low
overall cost of operation.
Figure 3 shows how to slide the nails in through the
IMPORTANT: When you first pick up an air
activated nail gun, ALWAYS ASSUME THAT
IT IS LOADED. Inspect for any nails before
connecting it to the air hose. Do not connect
the air supply until you are in position and
ready to operate the gun.

B. UNLOADING FASTENERS
C. CONNECTING TO AIR
Fasteners should be removed each time
you finish using the gun.
To connect the air hose to the air nozzle at
the rear of the gun:
To unload the gun:
1. Pull back on the female hose connector
sleeve.
1. Disconnect the air hose if still connect-
ed.
2. Press the fitting onto the nail gun air noz-
zle and release the sleeve. The female
fitting will lock onto the male gun fitting.
2. Press the button inside the spring handle
finger hole. Figure 5. Guide the spring
handle to the front of the gun. DO NOT
LET THE SPRING HANDLE SNAP
BACK TO ITS RESTING POSITION!
3. Listen for any air leaks. If no leaks are
detected, you are ready to test fire the
gun.
3. Press down on the nail stop and slide the
nails out through the nail slot. Figure 6.
Always disconnect the air supply when the
gun is not in use because (1) a pressurized
gun is dangerous and (2) constant pres-
sure will reduce the life of the O-rings
inside the gun.
Nail Stop
Prior to operating this nail gun, ensure that all
safety procedures are read and understood.
This tool is very simple to use and effectively
speeds production. However, ease of use and
routine production work may invite accidents.
Please practice safe work habits at all times
and always wear ANSI approved safety equip-
ment.

VII. OPERATIONS
D. TEST FIRING
E. ROUTINE USE
Whenever changing fastener size or composi-
tion of material being fastened, the gun should
be tested to ensure that the air pressure is set
correctly and the gun is working properly.
To operate the nail gun under routine con-
ditions, always wear safety glasses and:
1. Line up the gun nose with the area on the
workpiece you intend to fasten.
To test fire the gun, wear safety glasses
and follow the steps below:
2. Hold the gun straight and perpendicular
to the work surface.
1. Select a sample workpiece similar in
composition to the type of material you
will be fastening.
3. Firmly press safety nose against the
workpiece so that the gun nose rests on
the workpiece.
2. Firmly press the safety nose down
against the sample piece.
4. Pull trigger.
3. Pull trigger.
DO NOT DROP GUN. Repeated dropping will
result in misalignment of the nose and jam-
ming or breakage could occur. This is a preci-
sion tool, not a hammer.
4. Inspect your results. If the nail is set too
far into the workpiece, reduce the regu-
lated air pressure. If the nail is not set or
protrudes above the work surface,
increase the air pressure. However, do
not exceed the maximum air pressure
recommended for the gun or the hose
(120 p.s.i. for the gun).
This gun can also be continuously fired by
holding down on the trigger and firmly press-
ing the safety nose against the workpiece
each time you wish to shoot a fastener.
However, due to the inherent instability
and danger involved with that practice, we
strongly recommend against it.
5. Disconnect the air hose from the gun
when finished.
DO NOT FORGET TO DISCONNECT AIR
SUPPLY AND UNLOAD FASTENERS
WHEN FINISHED USING THE GUN.
6. Unload fasteners. See Section VII.B.

VII. OPERATIONS
E. ROUTINE USE (CONT’D)
Figure 7 shows using the gun
for a horizontal application.
Figure 8 shows using the gun
for a vertical application.
Caution: If the gun nose is positioned too
near the edge of the workpiece or is not held
straight, there is a chance that the fastener
will either split the workpiece or be deflected.
Do not hold the gun so that exhausted air is
blown into your face or someone else’s face.
Exhausted air will cause any dust near the
operating gun to become airborne; use a res-
pirator if using the gun in a dusty environment.
Caution: Compressed air is exhausted out of
the top, front of the gun and is directed down
toward the gun nose.

VIII. INSPECTION
WARNING: All inspections and/or any main-
tenance is to be performed with the air supply
disconnected from the tool.
Inspect and maintain the following items
daily:
5. Inspect air hoses and fittings for wear and
1. Check the air gun for any loose bolts or
air leaks. Loose bolts should be retight-
ened. Make sure that all lock washers are
in place. Air leaks are an indication that
internal seals are worn and should be
replaced.
tear and replace if necessary.
6. Inspect the air compressor to ensure that
it is operating properly. Follow the manu-
facturer’s recommended maintenance
schedule.
2. Make sure the safety nose and trigger are
functioning properly. Repair as neces-
sary. Do not use the gun with a broken or
modified safety nose.
7. Inspect the automatic lubricating system
if applicable and fill as required. Inspect
the in-line air and water filters if applica-
ble and change or clean as necessary.
3. The air gun should be kept clean. Wipe
8. Inspect the compressor regulator and/or
in-line regulator to ensure that they are
set correctly. Adjust accordingly.
off with a clean cloth daily.
4. If there is any mechanical problem with
the tool, it must be taken out of service
and repaired. If waiting for parts or repair,
the tool must be tagged “do not use” and
removed from the work area.
9. Oil regularly. See Section VI.B.

IX. MAINTENANCE
Maintenance requirements are minimal for
this nail gun. The two most common problems
with any nail gun are jamming and damaged
drivers. In both cases, the gun will need to be
partially diassembled to make the repairs.
A. JAMMING
To repair a jam:
1. Disconnect gun from the air supply.
The third most common problem is replacing
worn out O-rings. This is quite easily done, but
extensive disassembly will be required. We
suggest consulting with the Grizzly service
staff for special instructions if needed. Grizzly
has replacement parts and a special O-ring
rebuilding kit available for this tool. Please call
or write the appropriate service location listed
on page one of this manual for prices and
ordering information.
2. Remove any fasteners remaining in the
gun.
3. Open the nose by unlocking the safety
clip.
4. Using needle nose pliers, remove any
bent fasteners lodged in the gun nose.
5. Close the nose and re-lock the safety
clip.
Again, if repairs become necessary that are
beyond the scope of this manual, do not hes-
itate to call or write the appropriate service
location.
6. Re-load fasteners and connect nail gun
to the air supply.
7. Make sure the safety nose is functioning
correctly and that it slides freely in its
guide. Test fire into a sample piece after
following all operational and safety proce-
dures discussed earlier.
If jamming persists, make sure you are using
fasteners within the size range of this gun. If
jamming is due to worn or broken parts, repair
or replace them before placing the gun back
into service. For example, a worn or damaged
driver may cause jamming. If the driver tip is
worn, you may be able to recondition the tip
by filing it square again. In any event, you
must remove the damaged driver from the
gun. See Section IX.B.
Figure 9 shows the safety clip that keeps the nose of
the gun closed.
Figure 10 shows the nose open and the jammed nail
exposed. Remove with needle nose pliers.

IX. MAINTENANCE
B. DAMAGED DRIVER
To remove the driver:
C. O-RINGS AND RE-ASSEMBLY
Since the gun is disassembled, inspect the
condition of the visible O-rings. If the O-rings
show signs of wear and tear, they should be
replaced. Inspect the surfaces where the O-
rings seal for any possible rough spots which
will erode the new O-rings. When replacing
the O-rings, make sure that there is no dirt or
grit in the groove where the O-rings seat. Do
not stretch the O-rings or nick them on any
sharp edges or burrs. If cleaning parts with a
solvent, do not use a solvent that may deteri-
orate the O-rings.
1. Disconnect gun from the air supply and
remove any fasteners from the maga-
zine.
2. Loosen the 4 cap screws securing the
gun cap to the gun body sequentially.
3. Remove the four cap screws and the gun
cap and place them to one side.
4. With your fingers, reach into the air cylin-
der, grasp the main piston, and pull out
the driver.
To re-assemble the gun:
1. Before replacing O-rings, lubricate them
with a light grease that is non corrosive to
rubber.
5. Inspect driver condition and repair or
replace as necessary. Replacement dri-
vers are sold pre-attached to the main
piston and are referred to as the “com-
plete driver unit”.
2. IMPORTANT: Carefully position the dri-
ver tip into the plastic driver insert from
the top of the nail gun. You may have to
wiggle the driver so the main piston seats
into the cylinder. The driver has a T-
shaped cross section and will only fit one
way. If the driver is not seating, do not
force it. Remove the driver unit, rotate
180°, and try to reinstall it.
Air Cylinder
Gun Cap
3. Replace the cap on top of the gun.
Tighten the cap screws sequentially. If
the cap screws are not tightened even-
ly, the cap will not seat correctly, air
will leak, and the gun will not function.
Ensure that the washers are installed
under the cap screw heads.

IX. MAINTENANCE
X. TROUBLESHOOTING
This section covers some other potential prob-
lems and possible causes. If you have taken
the gun apart before, as in the above section,
you will realize that most problems can be
repaired on the job site with a few basic parts.
If you are heavily dependent upon this tool for
production work, it makes good sense to have
an O-ring repair kit and a complete driver unit
on hand just in case a problem does develop.
D. TESTING AFTER ASSEMBLY
To initially test the gun after a repair pro-
cedure:
1. Put on your safety glasses, reduce the
regulated air pressure to 30 PSI. Do not
put any fasteners into the magazine.
Connect the air hose.
The following list describes some potential
problems and solutions.
NOTE: It is important to reduce the ini-
tial test pressure so that damage to
the gun does not occur when firing
without any fasteners in the magazine.
1. LEAKS: A leak can usually be fixed by
simply loosening and retightening the
cap screws on the gun cap symmetri-
cally or providing more lubricant to
the O-rings.
2. Check for any leaking air. You will hear it
hissing or feel it rushing through the
spaces.
2. If the driver does not return to its starting
position, then the main piston O-ring may
be worn or broken.
3. If everything sounds normal, press the
safety nose down on a piece of wood and
pull the trigger a couple of times. Air
should be exhausted normally each time.
3. If air constantly leaks at the exhaust port,
then the head valve piston O-ring may be
worn or broken.
4. Disconnect the air hose. Adjust the regu-
lated air pressure back up to the mini-
mum required to set your fasteners. Load
the magazine with recommended fasten-
ers.
4. If air constantly leaks at the trigger, then
the trigger system O-rings may be worn
or broken.
5. If the gun misfires or over-drives the fas-
tener into the workpiece without manual-
ly changing the air pressure, then the
bumper may be worn or broken.
5. Re-connect the nail gun to the air supply.
6. Press the safety nose on a suitable test
material and pull the trigger. If the gun is
still not working properly, re-check your
repair procedure or call the appropriate
service location for advice.
6. If the wrong type of oil has been used for
lubrication, O-rings may swell and dis-
lodge from their grooves. This could
cause leaks anywhere in the gun.
See Section VII.D and VII.E. for more infor-
mation about testing and routine use.
Again, if you have a problem and would like
assistance, please call the appropriate service
department. They will be glad to assist you.
