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 H6144 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, install a  
1
4" NPT male quick connect fitting (not  
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!  
included) on the nailer and a matching  
1
4" NPT female fitting (not included) on  
the air hose. Regulate the air pressure on  
your air compressor to the minimum PSI  
for your model.  
An in-line filter/lubricator/regulator unit,  
shown in Figure 2, can be installed and  
should be located as close to the H6144  
as possible.  
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.  
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.

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 on the nose  
of the nailer acts as a secondary 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 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.

OPERATIONS  
4. Pull the magazine pusher all the way  
Loading  
back, then let it come forward until it  
rests against the end of the nail stick.  
When replacing nails in your Model  
H6144, follow these guidelines:  
Operating

Length: 114" -212  
Capacity: 40  
"
If you have not read the safety instruc-  
tions in this manual, do not operate  
the nailer.  
Angle:  
34°  
NOTICE: A number of manufacturers'  
nails may fit the Model H6144. However,  
for best performance, we recommend you  
use the following Grizzly nails:  
Before you operate your nailer, place one  
drop of the included oil into the quick con-  
nect fitting where the nailer connects to  
the air supply.  
G6085-G6088, G9545, G6090, G3693-  
G3697.  
To operate your nailer:  
To load your nailer:  
1. Connect the air supply to the quick  
connect fitting.  
1. DISCONNECT NAILER FROM THE  
AIR SUPPLY!  
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.  
2. Insert a nail stick into the T-slot at  
the top of the magazine as shown in  
Figure 3.  
3. Depress the safety yoke mechanism  
on 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.  
Pusher  
Deflection is caused when grain irreg-  
ularities, 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 4.  
Figure 3. Loading finish nails into nailer.  
3. Slide the nail stick all the way down to  
the nose of the nailer.  
-9-

Adjusting Depth  
The Model H6144 features a knurled  
adjustment knob (Figure 5) for setting  
the nail depth into the workpiece.  
Figure 4. Example of nail deflection.  
Besides damaging your workpiece,  
deflection can cause injury if your free  
hand is securing the workpiece in the  
location that the nail deflects.  
5. Pull the trigger. If the nail drove into  
the wood far enough, continue with  
your intended operations. If the nail  
went too far or not far enough, adjust  
the depth adjustment knob shown in  
Figure 5, in Adjusting Depth.

4. Depress the backstop (Figure 6)  
inside the magazine and slide the nail  
stick out of the magazine.  
Clearing Jammed  
Nails  
The most frequent situation with any type  
of nailer is a nail jam. A jammed nail must  
be cleared before using the nailer again.  
To clear a jammed nail from the dis-  
charge area on the Model H6144:  
Backstop  
1. DISCONNECT NAILER FROM THE  
AIR SUPPLY!  
Finger Tab  
Figure 6. Finger tab and backstop.  
5. Flip up the quick release latch located  
on top of the nailer nose assembly as  
shown in Figure 7.  
Always disconnect air from nailer  
whenever clearing a jammed nail!  
Figure 7. Releasing quick release latch.  
2. Push the finger tab (Figure 6) inside  
the magazine pusher, pull the pusher  
back slightly to clear it of the nail stick.  
While pressing the finger tab, slide the  
pusher forward over the nails until it  
rests near the nose.  
6. Remove the driver guide cover (Figure  
8).  
3. Continue pressing the finger tab, and  
push the nails up the magazine until  
they are released from the pusher.  
Figure 8. Removing driver guide cover.  
-11-  
H6144 34° Angle Finish Nailer–2½"  
 
7. The jammed nail should now be vis-  
ible; remove it from the discharge area  
with needle nose pliers.  
4. Remove the top cap.  
5. The top of the piston should now be  
visible inside the cylinder, which is  
housed in the head of the nailer.  
8. Replace the driver guide cover and  
snap the quick release latch back into  
operating position.  
6. Open the magazine.  
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.  
Replacing Pistons/  
O-Rings  
8. With a long flathead screwdriver or sim-  
ilarly 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 pushing the pis-  
ton shaft with the screwdriver.)  
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.  
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.  
10. Insert the new piston in the cylinder.  
Make sure that the grooves on the pis-  
ton shaft line up with those on the guide  
at the bottom of the cylinder. The new  
piston should easily slide into the cyl-  
inder. 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!  
11. After the piston is inserted correctly,  
close the magazine. Replace the top  
cap assembly and tighten the four cap  
screws.  
To replace a piston:  
1. DISCONNECT NAILER FROM THE  
AIR SUPPLY!  
12. For more assistance, or to install a  
complete O-ring set, refer to Parts  
Breakdown, Page 14.  
2. Remove all nails from the magazine.  
3. Remove the four cap screws on the  
top of the nailer, near the exhaust  
port.

CLEANING & LUBRICATION  
Cleaning  
Lubricating  
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  
9) before every use, or after two 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.  
The best option is to install a filter/lubrica-  
tor/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!
