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!
