Safety Instructions For Pneumatic Tools

H7945/H7946/H7995 26° Angle Nailer
-2-
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.
9. MAINTENANCE: Always disconnect
air from the nailer when servicing or
installing nails. During adjustments
or maintenance, a nailer connected
to air may fire accidentally, causing
serious personal injury.

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, 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.
Serious personal injury may result if
safety or operational information is
not understood or followed.

Compressed Air
System
The Model H7945/H7946/H7995 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.

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.
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!

Testing the 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 nail strip 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.
