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. WEAR 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 Nailers  
5. 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 with-  
out stretching. However, an overly  
long air hose in the work area may  
be a tripping hazard.  
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 pressurized  
oxygen or other combustible gases  
as a power source. Only use fil-  
tered, lubricated, and regulated  
compressed air.  
6. OPERATING QUESTIONS: If you  
are not sure about the intended  
operation, stop using the nailer.  
Seek formal training or research  
books or magazines that special-  
ize in pneumatic tools.  
3. SAFE HANDLING: Never point the  
nailer at others! Do not keep the  
trigger pulled when loading fasten-  
ers, 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.  
7. MAINTENANCE: Always discon-  
nect air from the nailer when ser-  
vicing or installing nails. During  
maintenance, a nailer connected  
to air may fire accidentally, caus-  
ing serious personal injury.  
8. COMPRESSED AIR RATING: Do  
not connect the nailer to com-  
pressed air that exceeds 120 PSI.  
4. CLEANING: Never use gasoline or  
other flammable liquids to clean the  
nailer; vapors in the nailer will ignite  
by a spark and cause it to explode.  
9. CHECK VALVE: Do not use a  
check valve or any other fitting that  
allows air to remain in the tool.  
-2-  
H7679 2" Nailer Kit  
 
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.  
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, this  
nailer discharges at up to 90 deci-  
bels. To protect your hearing, always  
wear ANSI approved ear protection  
when operating this nailer.  
Nailer/stapler accidents routinely hap-  
pen while moving the gun to another  
location, such as up ladders, to anoth-  
er room, or even another job site.  
Always disconnect the gun immedi-  
ately 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.

Compressed Air  
System  
The Model H7679 is designed to be oper-  
ated at 60–100 PSI using clean, dry, regu-  
lated, compressed air. DO NOT exceed  
the maximum operating pressure for  
your model.  
Before using your new nailer, regulate the  
air pressure on your air compressor to the  
minimum PSI for your model.  
Exceeding the maximum permissible  
operating pressure may cause the  
nailer to explode, blowing metal frag-  
ments in all directions. To protect  
yourself from serious personal injury,  
DO NOT allow your air compressor to  
exceed the recommended pressure  
when connected to this nailer!  
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  
protect your tool from damaging water  
build-up, allow you to adjust and maintain  
constant air pressure to your tool, and  
save you the inconvenience of having to  
manually lubricate 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.

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.  
Safety Nose  
Mechanism  
A safety mechanism on the nose of the  
nailer protects against accidental firing.  
When the trigger is pressed, the nailer will  
not fire until the safety nose mechanism is  
depressed.  
— If the nailer does not fire, then the  
safety nose mechanism is working  
correctly.  
— If the nailer does fire when you  
do this, immediately disconnect the  
nailer from the air supply and call  
Grizzly Technical Support at (570)  
546-9663 for help.  
Before you use your nailer for the first  
time, check the safety nose mechanism to  
ensure proper function. To do this:  
1. DISCONNECT NAILER FROM THE  
AIR SUPPLY!  
— If the nailer fires when the trigger  
is pulled, without the safety nose  
mechanism being depressed, then  
immediately disconnect the nailer  
from the air supply and call Grizzly  
Technical Support at (570) 546-  
9663 for help.  
2. Make sure the magazine is empty and  
contains no nails.  
3. Make sure the trigger and the safety  
nose mechanism move up and down  
without sticking.  
— If you find that the safety nose  
mechanism is not working properly,  
check the lubrication of its sliding  
components.  
4. Connect the nailer to the air supply.  
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.

3. Depress the safety nose mechanism  
Adjusting Depth  
against your workpiece.  
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.  
A depth adjustment knob is attached to the  
nose for setting the nail depth.  
To adjust the depth:  
1. DISCONNECT NAILER FROM THE  
AIR SUPPLY!  
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, as shown in Figure 5.  
2. Rotate the adjustment knob (Figure  
6) clockwise to drive the nails deeper  
or counterclockwise to drive the nails  
shallower.  
Besides damaging your workpiece,  
deflection can cause injury if your free  
hand is securing the workpiece in the  
location that the nail deflects.

3. Connect nailer to the air supply and  
test the nail depth, and repeat this  
entire procedure if necessary until the  
nail depth is satisfactory.

5. Pull the trigger.  
— If the nail drove into the wood far  
enough, continue with your intended  
operations.  
— If the nail either went too far or not  
far enough, then go to the Adjusting  
Depth subsection on this page.

jammed nail.  
6. Watch the discharge area and push  
the top of the piston with your finger.  
You will see the piston shaft slide  
down the discharge area.  
The piston repair kit part number for the  
Model H7679 is #PH7679085. For your  
convenience, refer to the parts breakdown  
during this procedure to identify parts and  
their locations inside the nailer.  
7. With a long flathead screwdriver or  
similarly shaped tool, push the piston  
shaft back inside the nailer until you  
can grip the piston head and remove  
it from the cylinder. (Be careful not to  
scratch the discharge area when push-  
ing the piston shaft with the screw-  
driver.)  
8. Place a new O-ring on the new piston  
and apply a thin film of the nailer lubri-  
cating oil on the O-ring.  
9. Insert the new piston in the cylinder.  
Make sure that the grooves on the  
piston shaft line up with those on the  
guide at the bottom of the cylinder.  
The new piston should easily slide  
into the cylinder. DO NOT force the  
piston into the cylinder! If the piston  
is not easily inserted, double-check the  
alignment of the piston shaft with the  
grooves on the guide.  
Always disconnect air from nailer  
whenever servicing! During mainte-  
nance, a nailer connected to air may  
fire accidentally, causing serious  
personal injury!  
To replace a piston and O-ring(s):  
1. DISCONNECT NAILER FROM THE  
AIR SUPPLY!  
10. After the piston is inserted correctly,  
close the magazine. Replace the rear  
cap assembly and tighten the 4 cap  
screws.  
2. Remove all nails from the magazine  
cartridge.  
11. For more assistance, or to install a  
complete O-ring set, refer to the appro-  
priate breakdown diagram in the back  
of this manual for component loca-  
tions.  
3. Remove the four cap screws on the  
head of the nailer, near the exhaust  
port, and remove the cylinder cover.

CLEANING & LUBRICATION  
Lubricating  
Cleaning  
Use a good solvent to clean the nose  
assembly of the nailer. Always be sure  
that the nailer is dry before using it again.  
Special 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 8)  
every 2 hours of continuous use.  
Do not allow dust, chips, sand, etc. into  
the air connectors or into the body of the  
nailer; this may result in leaks and dam-  
age to the nailer and the air couplings.  
Wipe off any excess oil near the nailer  
exhaust to avoid dust build-up. When  
the oil that was included with the nailer  
has been completely used, replace with  
Grizzly Model G2820 Pneumatic Tool Oil.  
Another option to manual oiling would be  
to simply 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.  
Never use gasoline or other flamma-  
ble liquids to clean this tool. Vapors  
in the tool may ignite, causing the  
tool to explode. Ignoring this warning  
may lead to serious personal injury or  
even death!
