17. DISCONNECT TOOLS before  
servicing, 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/balance at all times.  
11. WEAR PROPER APPAREL. Do  
not wear loose clothing, gloves,  
neckties, rings, bracelets, or other

THE  
RECOMMENDED  
accessories. The use of improper  
accessories may cause risk of  
injury.  
20. CHECK FOR DAMAGED PARTS  
BEFORE USING. Check for binding  
and alignment of parts, broken  
parts, part mounting, loose bolts,  
and any other conditions that may  
affect machine operation. Repair or  
replace damaged parts.  
12. ALWAYS  
USE  
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.  
13. WEAR APPROVED HEARING  
PROTECTION. Air escaping from  
pneumatic tools can exceed safe  
exposure limits and may cause  
hearing damage with prolonged  
exposure.  
21. NEVER LEAVE UNATTENDED  
TOOL CONNECTED TO AIR.

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.  
2. COMBUSTIBLE GASES: Never con-  
nect the nailer to pressurized oxygen  
or other combustible gases as an air  
source. Only use filtered, lubricated,  
and regulated compressed air.  
3. SAFE HANDLING: Never point the  
nailer at others! Do not keep the trig-  
ger pulled when loading fasteners,  
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.  
6. 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 haz-  
ard.  
7. OPERATING QUESTIONS: If you  
are not sure about the intended oper-  
ation, stop using the nailer. Seek  
formal training.  
8. 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. MAINTENANCE: Always disconnect  
air from the nailer when servicing or  
installing nails. During maintenance,  
a nailer connected to air may fire acci-  
dentally, causing serious personal  
injury.  
4. MODIFICATIONS: DO NOT modify  
this tool or bypass the safety nose  
mechanism.  
5. CHECK VALVE: Do not use a check  
valve or any other fitting that allows  
air to remain in the tool.  
10. COMPRESSED AIR RATING: Do  
not connect the nailer to compressed  
air that exceeds 120 PSI.

Never point these nailers at yourself  
or another person! Always pay atten-  
tion to the direction these nailers are  
pointed. Use these tools with respect  
and caution to lessen the possibil-  
ity of operator or bystander injury.  
Ignoring this warning may result in  
serious personal injury.  
Read the manual before operation.  
Become familiar with these nailers,  
their safety instructions, and their  
operation before beginning any work.  
Serious personal injury may result if  
safety or operational information is  
not understood or followed.  
Nailer accidents routinely happen  
while moving the gun to another  
location, 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 compres-  
sor is disconnected from its power  
source!  
No list of safety guidelines can be  
complete. Every shop environment  
is different. Always consider safe-  
ty first, as it applies to your indi-  
vidual 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.  
Operating these nailers 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  
operating this equipment. In addi-  
tion, these nailers discharge at up  
to 85-90 decibels. To protect your  
hearing, always wear ANSI approved  
ear protection when operating these  
nailers.

Compressed Air  
System  
The Model H8232 is designed to be oper-  
ated at the following air pressures using  
clean, dry, regulated, compressed air:  
Nailer  
Operating Air Pressure  
Framing ................................... 80–110 PSI  
Finish....................................... 60–100 PSI  
Palm ........................................ 70–100 PSI  
Exceeding the maximum permissible  
operating pressure may damage the  
nailers and cause them to malfunc-  
tion. To protect yourself from per-  
sonal injury, DO NOT allow the air  
pressure to exceed the recommended  
pressure for these nailers!  
DO NOT exceed the 120 PSI maximum  
operating pressure for your nailer.  
Before using your new nailers, regulate the  
air pressure to find the optimum setting  
within the specified operating range. Start  
by testing the nailer at a low setting, then  
increase the air pressure as needed for  
satisfactory results.  
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.  
An in-line filter/lubricator/regulator unit can  
be installed, as depicted in Figure 2.  
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.

of its sliding components.  
Framing/Finish  
Nailer Safety Nose  
Mechanism  
Safety Check #2  
A safety mechanism on the nose of the  
framing/finish nailer protects against acci-  
dental firing. When the trigger is pressed,  
the nailer will not fire until the safety nose  
mechanism is depressed.  
1. Lift the nailer from the scrap piece of  
wood so that the safety nose is not  
depressed, point the nailer down and  
away from yourself and others, then  
pull the trigger.  
Before you use your nailers for the first  
time, perform these safety checks to  
ensure the safety nose mechanisms are  
operating properly.  
— If the nailer does not fire when the  
trigger is pulled without the safety  
nose mechanism being depressed,  
then the nailer is working properly.  
Safety Check #1  
— 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!  
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.  
The safety mechanism is a mechanical  
device that can fail. Never rely on this  
mechanism as an excuse to point the  
framing/finish nailer at yourself or any  
bystanders. Serious injury may occur.  
4. Connect the nailer to the air supply.  
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.  
DO NOT attempt to modify or bypass  
the safety nose mechanism to make  
the framing/finish nailer fire without  
pushing the safety nose down.  
— If the nailer does not fire, then the  
safety nose mechanism is working  
correctly. Proceed to Safety Check  
#2.  
— 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.

3. Depress the safety nose mechanism  
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 deflec-  
tion.  
Note: 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 7.  
Figure 6. Loading nails into magazine  
(finish nailer).  
Besides damaging your workpiece,  
deflection can cause injury if your free  
hand is in the path of the deflecting  
nail.  
4. Slide the nails all the way down to the  
nose of the nailer.  
5. Release the magazine pusher by pull-  
ing back on the pusher and pushing in  
on the catch lever.  
Operating  
If you have not read the safety instruc-  
tions in this manual, do not operate the  
nailer.  
Figure 7. Example of nail deflection.  
5. Pull the trigger.  
Before you operate your nailers, place  
five to six drops of the included oil into the  
quick connect fitting where the nailer con-  
nects to the air supply.  
— If the nail drove into the wood far  
enough, continue with your intended  
operations.

2. Use a 4mm hex wrench to loosen the  
cap screw shown in Figure 8.  
4. Hold the nailer in place until the sliding  
depth guide is completely depressed  
up into the nailer and the nail is fully  
hammered into the workpiece.  
3. Move the nose tip away from the nail-  
er body to decrease penetration, and  
toward the nailer body to increase  
penetration.  
Note: You can stop the nailer at any  
time by simply lifting it away from  
the nail. This is useful if you do not  
want to countersink the nail into the  
workpiece.  
Note: The rubber nose tip can be  
removed to increase nail penetration  
even further.  
If the nailer is allowed to continue  
hammering until it stops by itself, it will  
countersink the nail to an approximate  
depth of 2mm or 564".

the piston shaft with the grooves on the  
guide.  
8. After the piston is inserted correctly,  
place the cylinder back in the nailer  
housing. If seated correctly, the cylin-  
der will snap into place.  
10. After the piston is inserted correctly,  
close the magazine. Replace the rear  
cap assembly and secure it with the  
four cap screws removed in Step 3.  
9. Push the cylinder collar down into the  
housing as far as it will go. The horizon-  
tal air slots on the cylinder sides should  
be visible.  
Note: For more assistance, or to install  
a complete O-ring set, refer to the  
appropriate breakdown diagram in the  
back of this manual for component  
locations.  
10. Replace the rear cap and secure it  
with the four cap screws removed in  
Step 3.  
11. Re-install the flat washer, compression  
spring, depth guide, and nose piece  
onto the front of the nailer, then use  
a 19mm wrench to tighten the nose  
piece.

CLEANING & LUBRICATION  
Cleaning  
Lubricating  
Use non-flammable solvent to clean the  
nose assembly of the nailer. Always be  
sure that the nailer is dry before using it  
again.  
Standard pneumatic tool 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 12) 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 damage  
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 it 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.  
Never clean this tool with gasoline  
or other flammable liquids. Vapors  
in the tool may ignite, causing the  
tool to explode. Ignoring this warning  
may lead to serious personal injury or  
even death!
