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.
2. COMBUSTIBLE GASES: Never
connect the nailer to pressur-
ized oxygen or other combustible
gases as a power source. Only
use filtered, lubricated, and regu-
lated compressed air.
3. SAFE HANDLING: Never point
the nailer at others! Do not keep
the trigger 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. AIR HOSE: 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 hazard.
Additional Safety Instructions for Nailers
5. COMPRESSED AIR RATING: Do
not connect the nailer to compressed
air that exceeds 120 PSI.
6. CHECK VALVE: Do not use a check
valve or any other fitting that allows
air to remain in the tool.
7. CLEANING: Never use gasoline or
other flammable liquids to clean the
nailer; vapors in the nailer may ignite
by a spark and cause the nailer to
explode.
8. OPERATING QUESTIONS: If you
are not sure about the intended
operation, stop using the nailer.
Seek formal training or research
sources that specialize in pneumatic
tools.

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, the
intensity of sound made by this nailer
at discharge can reach 90 decibels.
To protect your hearing, always wear
ANSI approved ear protection when
operating this nailer.
Never point this nailer at yourself or
another person! Always pay attention
to the direction this nailer is pointed.
Use this tool with respect and caution
to lessen the possibility of operator or
bystander injury. Ignoring this warning
may result in serious personal injury.
Nailer accidents routinely happen
while moving the gun to another loca-
tion, 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!
No list of safety guidelines can be
complete. Every shop environment is
different. Always consider safety first,
as it applies to your individual working
conditions. Use this and other tools
with caution and respect. Failure to
do so could result in serious personal
injury, damage to equipment or poor
work results.
Read the manual before operation.
Become familiar with these nailers,
their safety instructions, and opera-
tion before beginning any work.

Compressed Air
System
The Model H7949/H7950/H7951 is
designed to be operated at 70–110 PSI
using clean, dry, regulated, compressed
air. DO NOT exceed 120 PSI.
Before using your new nailer, set the air
pressure on your regulator to the mini-
mum PSI for your model.
An in-line filter/lubricator/regulator unit,
depicted in Figure 2, can be installed and
should be located as close to the nailer
as possible.
This filter/lubricator/regulator unit will pro-
tect your tool from damaging water build-
up, allow you to adjust and maintain con-
stant air pressure to your tool, and save
you the inconvenience of manually lubri-
cating your tool every time you use it.

compressed air system, always follow the
connection instructions that come with
the unit.
Exceeding the maximum permissible
operating pressure may damage the
seals, gaskets and hammer mecha-
nism of your nailer. DO NOT allow
your air compressor to exceed the
recommended pressure when con-
nected to this nailer or serious per-
sonal injury may result!

H7949/H7950/H7951 Nailer -7-
Testing Safety Nose
Mechanism
A safety mechanism (bump fire) on the
nose of the nailer protects against acci-
dental firing. This mechanism is activated
when nails are loaded into the magazine.
The nailer will not fire when the trigger
is pulled until the safety nose is fully
depressed.
Before you use your nailer for the first
time, check the safety nose mechanism
to ensure proper function.
5. Without pressing the trigger, depress
the safety nose mechanism against a
scrap piece of wood that is clean and
free of any knots, nails, or other foreign
objects.
— If the nailer does not fire, then the
safety nose mechanism is working
correctly.
— If the nailer does fire when you
depress the safety nose, immedi-
ately disconnect the nailer from the
air supply and call Grizzly Technical
Support at [phone] for help.
6. Without depressing the safety nose,
point the nailer in a safe direction, and
pull the trigger.
— If the nailer does not fire, then the
safety nose mechanism is working
correctly.
— If the nailer does fire when the
trigger is pulled, without the safety
nose mechanism being depressed,
immediately disconnect the nailer
from the air supply and call Grizzly
Technical Support at (570) 546-
9663 for help.
The safety mechanism is a mechanical
device that can fail. Never rely on this
mechanism as an excuse to point the
nailer at yourself or any bystanders.
Serious injury may occur.
To verify that the safety nose is working
correctly:
1. DISCONNECT NAILER FROM THE
AIR SUPPLY!
2. Insert a coil of nails in the magazine
(see Page 8 for instructions).
3. Make sure the trigger and the safety
nose mechanism move up and down
without sticking.
4. Connect the nailer to the air supply.
Point the nailer away from you and
others when connecting the air supply.
The nailer can cycle and discharge a
nail when the air supply is connected.
Ignoring this warning may result in
serious personal injury.

Using the Nailer
Before you operate your nailer, place five
to six drops of air tool oil into the quick
connect fitting where the nailer connects
to the air supply.
To operate your nailer:
1. Connect the air supply to the quick
connect fitting on your nailer.
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.
3. Depress the safety nose mechanism
against your workpiece.
Note: Deflection is caused when
grain irregularities, knots or foreign
objects inside the wood cause the
nail to change its path, resulting in
the nail puncturing the surface of the
workpiece.
Besides damaging your workpiece,
deflection can cause injury if your free
hand is securing the workpiece in the
location that the nail deflects.
5. Pull the trigger.
— If the nail penetrates the wood to the
depth you want, continue with your
intended operations.
— If the nail either went too far or not
far enough, adjust the depth of fire
by following the procedures listed on
Page 12.
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
deflection (illustrated below in Figure
11).
Figure 11. Example of nail deflection.
Read the manual before operation.
Become familiar with these nailers,
their safety instructions, and opera-
tion before beginning any work.
Serious personal injury may result if
safety or operational information is
not understood or followed.

Replacing
Pistons/O-Rings
If you need to replace piston parts in your
nailer, you can purchase a piston repair kit
from Grizzly: call 1-800-523-4777.
The Piston Repair Kit part number for
Model H7949 is PH7949103; the Piston
Repair Kit part number for Model H7950
is PH7950103; the Piston Repair Kit part
number for Model H7951 is PH7951104.
Refer to the parts breakdown during this
procedure to identify parts and their loca-
tions inside the nailer.
4. Push the top of the piston down with
your finger as far as it will go; this will
push the piston driver into the nose of
the nailer.
5. Insert a stiff rod or wire of the same
diameter as your nails into the dis-
charge area of the nose and use it
to push the piston driver up until the
piston head clears the top of the cyl-
inder. (Be careful not to scratch the
discharge area or the piston cylinder.)
6. Grip the piston head by hand and
remove the piston assembly from the
cylinder.
7. Clean all metal parts with an auto-
motive grade solvent. Clear all ports
and blow the solvent away with com-
pressed air.
8. Replace any part that shows damage
of heavy wear. Relubricate the tool.
9. Apply a thin film of the nailer lubricat-
ing oil on the new O-ring and place
it on the new piston. Install any other
parts included in the piston repair kit.
10. Insert the new piston in the cylinder.
With the magazine cover open, gently
push the piston down to make sure the
piston driver moves freely into the driv-
ing hole.
Note: DO NOT force the piston into
the cylinder! If the piston 'hangs' in the
cylinder, double check the fit between
piston and O-ring and imake sure the
cylinder is clean.
11. Make sure that the cap gasket is in
place, then secure the cap to the nailer
body by tightening the 4 cap screws.
To replace a piston and O-ring(s):
1. DISCONNECT NAILER FROM THE
AIR SUPPLY!
2. Remove all nails from the magazine.
3. Remove the four screws that secure
the nailer cap and remove the cylinder
cap.
Always disconnect the air supply
from the nailer whenever servicing!
During maintenance, a nailer con-
nected to air may fire accidentally,
causing serious personal injury!

CLEANING & LUBRICATING
Cleaning
Use an automotive grade solvent such as
Sprayway C-60® (G2544 in the Grizzly
catalog) to clean the nose assembly of the
nailer. Always be sure that the nailer is dry
before using it again.
Do not allow dust, chips, or sand into the
air connectors or into the body of the nail-
er; this may result in leaks and damage to
the nailer and the air couplings.
Lubricating
Special 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 15) every 2 hours of
continuous use.
Wipe off any excess oil near the nailer
exhaust to avoid dust build-up. When
the oil that was included with your nailer
has been completely used, replace with
Grizzly Model G2820 Pneumatic Tool Oil.
An efficient alternative to oiling your tool
by hand is to install a lubricator in your air
compressor line. If your air compressor
line already has a lubricator, then regular
lubrication of your nailer will not be neces-
sary. Just make sure there is always oil in
the lubricator.
Figure 15. Lubricating the nailer at the
air inlet.
Never use gasoline to clean this tool.
Use extreme caution when using any
solvent cleaner. Always clean the tool
in a well-ventilated area and never if
sparks or open flames are present.
Remember that electrical machinery
can produce sparks during normal
operation. Ignoring this warning can
cause serious personal injury or even
death!
