Safety Instructions For Pneumatic Tools
17. DISCONNECT TOOLS before ser-
vicing, changing accessories, or
moving to another location.
10. USE PROPER AIR HOSE for the
tool. Make sure your air hose is in
good condition and is long enough to
reach your work without stretching.
18. DO NOT OVERREACH. Keep
proper footing and balance at all
times.
11. WEAR PROPER APPAREL. Do not
wear loose clothing, gloves, neck-
ties, rings, bracelets, or other jew-
elry which may get caught in moving
parts. Non-slip footwear is recom-
mended. Wear a protective hair cov-
ering to contain long hair.
19. USE
THE
RECOMMENDED
ACCESSORIES. Consult owner’s
manual for recommended acces-
sories. The use of improper acces-
sories may cause risk of injury.
12. ALWAYS USE ANSI APPROVED
SAFETY GLASSES. Also use a
face or dust mask if cutting operation
is dusty. Everyday eyeglasses only
have impact resistant lenses, they
are NOT safety glasses.
20. CHECK FOR DAMAGED PARTS
BEFORE USING. Check for bind-
ing and alignment of parts, broken
parts, part mounting, loose bolts,
and any other conditions that may
affect machine operation. Repair or
replace damaged parts.
13. ALWAYS WEAR ANSI APPROVED
HEARING PROTECTION.
21. NEVER LEAVE UNATTENDED
TOOL CONNECTED TO AIR.
Disconnect the air hose and do not
leave tool until it is relieved of any
built up pressure.
14. SECURE WORK. Use clamps or a
vise to hold work when practical. It is
safer than using your hand and frees
both hands to operate tool.
22. NEVER ALLOW UNTRAINED
USERS TO USE THIS TOOL
WHILE UNSUPERVISED.
15. MAINTAIN TOOLS WITH CARE.
Keep tools lubricated and clean
for best and safest performance.
Follow instructions for lubricating
and changing accessories.
23. IF YOU ARE UNSURE OF THE
INTENDED OPERATION, STOP
USING THE TOOL. Seek formal
training or research books or maga-
zines that specialize in pneumatic
tools.
16. REDUCE
THE
RISK
OF
UNINTENTIONAL STARTING. Do
not carry tool with hand on trig-
ger and always disconnect from air
when not in use.

Additional Safety Instructions for Staplers
1. HAND INJURIES: Do not place
your hands near the staple point
of entry. A staple can deflect and
tear through the surface of the
workpiece, puncturing your hand
or fingers.
5. COMPRESSED AIR RATING: Do
not connect the stapler to com-
pressed 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.
2. COMBUSTIBLE GASES: Never
connect the stapler to pressur-
ized oxygen or other combustible
gases as a power source. Only
use filtered, lubricated, and regu-
lated compressed air.
7. CLEANING: Never use gasoline or
other flammable liquids to clean the
stapler; vapors in the stapler may
ignite by a spark and cause the sta-
pler to explode.
3. SAFE HANDLING: Never point
the stapler at others! Do not keep
the trigger pulled when loading
fasteners, carrying, or holding
tool. Carry the stapler only by the
handle, never by any other part.
Do not carry the stapler by the air
hose. Disconnect the stapler from
the air hose when going up and
down ladders.
8. OPERATING QUESTIONS: If you
are not sure about the intended
operation, stop using the stapler.
Seek formal training or research
sources that specialize in pneumatic
tools.
9. MAINTENANCE: Always disconnect
air from the stapler when servicing or
installing staples. During adjustments
or maintenance, a stapler connected
to air may fire accidentally, causing
serious personal injury.
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.

Never point this stapler at yourself or
another person! Always pay attention
to the direction this stapler 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.
Operating this stapler 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 sta-
pler at discharge can reach 90 deci-
bels. To protect your hearing, always
wear ANSI approved ear protection
when operating this stapler.
Stapler 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 staplers,
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.

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.
Compressed Air
System
The Model H7947/H7948 is designed to
be operated at 70–110 PSI using clean,
dry, regulated, compressed air. DO NOT
exceed 120 PSI.
Exceeding the maximum permissible
operating pressure may damage the
seals, gaskets and hammer mecha-
nism of your stapler. DO NOT allow
your air compressor to exceed the
recommended pressure when con-
nected to this stapler or serious per-
sonal injury may result!
An in-line filter/lubricator/regulator unit,
depicted in Figure 2, can be installed and
should be located as close to the stapler
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.

5. Without pressing the trigger, depress
the safety nose mechanism against a
scrap piece of wood that is clean and
free of any knots, staples, or other for-
eign objects.
Testing Safety Nose
Mechanism
A safety mechanism (bump fire) on the
nose of the stapler protects against acci-
dental firing. This mechanism is activated
when staples are loaded into the maga-
zine. The stapler will not fire when the
trigger is pulled until the safety nose is
fully depressed.
— If the stapler does not fire, then the
safety nose mechanism is working
correctly.
— If the stapler does fire when you
depress the safety nose, immedi-
ately disconnect the stapler from the
air supply and call Grizzly Technical
Support at (570) 546-9663 for help.
Before you use your stapler for the first
time, check the safety nose mechanism
to ensure proper function.
6. Without depressing the safety nose,
point the stapler in a safe direction, and
pull the trigger.
The safety mechanism is a mechanical
device that can fail. Never rely on this
mechanism as an excuse to point the
stapler at yourself or any bystanders,
otherwise, serious injury may occur.
— If the stapler does not fire, then the
safety nose mechanism is working
correctly.
— If the stapler does fire when the
trigger is pulled, without the safety
nose mechanism being depressed,
immediately disconnect the stapler
from the air supply and call Grizzly
Technical Support at (570) 546-
9663 for help.
To verify that the safety nose is working
correctly:
1. DISCONNECT STAPLER FROM THE
AIR SUPPLY!
2. Insert a strip of staples 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 stapler to the air supply.
Point the stapler away from you and
others when connecting the air supply.
The stapler can cycle and discharge a
staple when the air supply is connect-
ed. Ignoring this warning may result in
serious personal injury.

CLEANING & LUBRICATING
Cleaning
Lubricating
Special pneumatic tool oil has been
included with your new Grizzly stapler to
help maintain its useful life. Place two to
six drops of oil in the stapler air inlet (as
shown in Figure 13) every two hours of
continuous use.
Use an automotive grade solvent such as
Sprayway C-60® (G2544 in the Grizzly
catalog) to clean the nose assembly of the
stapler. Always be sure that the stapler is
dry before using it again.
Do not allow dust, chips, or sand into the
air connectors or into the body of the sta-
pler; this may result in leaks and damage
to the stapler and the air couplings.
Wipe off any excess oil near the stapler
exhaust to avoid dust build-up. When the
oil that was included with your stapler
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 stapler will not be nec-
essary. Just make sure there is always oil
in the lubricator.
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
in the area can produce sparks during
normal operation. Ignoring this warn-
ing can cause serious personal injury
or even death!

air inlet.
