Additional Safety Instructions for Nailers  
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.  
5. HOSE USAGE: 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.  
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.

Compressed Air  
System  
The Model H6146 is designed to be oper-  
ated at 70-120 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 yoke mechanism against a  
scrap piece of wood that is clean and  
free of any knots, nails, or other foreign  
objects.  
Safety Yoke  
A safety yoke mechanism (bump fire) on  
the nose of the nailer acts as a second-  
ary safety device. When the trigger is  
pressed, the nailer will not fire until the  
safety yoke mechanism is depressed.  
— If the nailer does not fire, then the  
safety yoke mechanism is working  
correctly.  
Before you use your nailer for the first  
time, check the safety yoke mechanism to  
ensure proper function. To do this:  
— 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.  
1. DISCONNECT NAILER FROM THE  
AIR SUPPLY!  
— If the nailer fires when the trigger  
is pulled, without the safety yoke  
mechanism being depressed, then  
the nailer is not working properly.  
2. Make sure the magazine is empty and  
contains no nails.  
3. Make sure the trigger and the safety  
yoke mechanism move up and down  
without sticking.  
— If either of these two conditions  
develop after you have used your  
nailer for a period of time, check the  
lubrication of these mechanisms.  
4. Connect the nailer to the air supply.  
The safety yoke is  
a
mechanical  
device that can fail. Never rely on the  
safety yoke mechanism as an excuse  
to point the nailer at yourself or any  
bystanders. Serious injury may occur.

nose of the nailer.  
5. Release the catch lever. The pusher  
slides forward until it rests against the  
nail stick.  
2. Grip the nailer firmly, pull the maga-  
zine pusher back, and engage the  
catch lever as shown in Figure 3.  
Operating  
If you have not read the safety instruc-  
tions in this manual, do not operate  
the nailer.  
Pusher  
Before you operate your nailer, place five  
to six drops of the included oil into the  
quick connect fitting where the nailer con-  
nects to the air supply.  
Catch Lever  
Figure 3. Sliding pusher toward the  
catch lever.  
To operate your nailer:  
3. Insert a strip of nails, pointed-end  
down, into the magazine as shown in  
Figure 4.  
1. Connect the air supply to the quick  
connect fitting.  
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. Pull the trigger and depress the safety  
Adjusting Depth  
yoke mechanism on your workpiece.  
4. Before pressing 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.  
The nose of the gun houses a depth adjust-  
ment mechanism 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. If the nail is driven too far into the  
workpiece, loosen the cap screw on  
the safety nose with a 4mm wrench, as  
shown in Figure 6.  
Besides damaging your workpiece,  
deflection can cause injury if your free  
hand is securing the workpiece in the  
location that the nail deflects.

3. Slide the safety nose (Figure 6) toward  
the nailer body to drive nails deeper,  
and away from the body to drive nails  
less deep.  
Figure 5. Example of nail deflection.  
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 section on this  
page.  
4. Tighten the safety nose cap screw  
each time after making adjustments.  
5. Connect to the air.  
6. Pull the trigger and depress the safety  
yoke mechanism on your workpiece to  
test the depth adjustment.

Single/Bump Fire  
Mode  
Clearing Jammed  
Nails  
The nailer is designed to fire one nail at a  
time, or one after another, using the safety  
yoke mechanism.  
A jammed nail must be cleared before  
using the nailer again. The two places  
where a nail can get jammed are the maga-  
zine and the discharge area.  
To operate your nailer in single fire  
mode:  
To clear a jammed nail from the maga-  
zine:  
1. Depress the safety yoke mechanism  
against the workpiece.  
1. DISCONNECT NAILER FROM THE  
AIR SUPPLY!  
2. Pull the trigger, then remove your finger  
2. Pull back and lock the magazine push-  
from the trigger after the nail is driven.  
er.  
To operate your nailer in bump fire  
mode:  
3. Remove the nail stick.  
4. Locate and remove the jammed nail  
with needle nose pliers. Release the  
catch lever and let the pusher slide to  
front of the magazine.  
1. Pull the trigger.  
2. Press the safety yoke mechanism  
against your workpiece and raise it  
after the nail is driven.  
To clear a jammed nail from the dis-  
charge area:  
3. Hold the trigger and repeat Step 2 to  
drive more nails.  
1. DISCONNECT NAILER FROM THE  
AIR SUPPLY!  
2. Pull back and lock the magazine push-  
er in place.  
3. Remove all nails from the magazine.  
4. Locate the nail in the nailer nose, dis-  
lodge the nail with a tool that will fit in  
the slot on the underside of the nose.  
5. Throw the damaged nail away and  
insert a new nail stick that only con-  
tains clean, undamaged nails. DO  
NOT use dirty or damaged nails!  
6. Release the catch lever and let the  
pusher slide to the front of the maga-  
zine.

5. The top of the piston should now be  
visible inside the cylinder, which is  
housed in the head of the nailer.  
Replacing Pistons/O-  
Rings  
6. Open the magazine.  
If you use your nailer day in and day  
out, repair pistons are cheap insurance  
against wasted down time and lost profits,  
in the event that a piston or piston shaft  
becomes worn out.  
7. 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.  
8. 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.)  
9. Place a new O-ring on the new piston  
and apply a thin film of the nailer lubri-  
cating oil on the O-ring.  
Always disconnect air from nailer  
whenever servicing! During mainte-  
nance, a nailer connected to air may  
fire accidentally, causing serious  
personal injury!  
10. 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.  
To replace a piston:  
1. DISCONNECT NAILER FROM THE  
AIR SUPPLY!  
11. After the piston is inserted correctly,  
close the magazine. Replace the top  
cap assembly and tighten the 4 cap  
screws.  
2. Remove all nails from the magazine  
cartridge.  
3. Remove the four cap screws on the  
top of the nailer, near the exhaust  
port.  
12. For more assistance, or to install a  
complete O-ring set, refer to the appro-  
priate breakdown diagram in the back  
of this manual.  
4. Remove the top cap.

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  
7) before every use, or after 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 install a lubricator in your air compres-  
sor line. If your air compressor line already  
has a lubricator, then regular lubrication  
of your nailer will not be necessary. Just  
make sure there is always oil in the lubri-  
cator.  
As mentioned before, the best option is  
to install a filter/lubricator/regulator unit in  
your air line.  
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!
