not wear loose clothing, gloves,
neckties, rings, bracelets, or other
jewelry which may get caught in
moving parts. Non-slip footwear is
recommended. Wear a protective
hair covering to contain long hair.
12. ALWAYS USE SAFETY GLASSES.
Also use a face or dust mask if cut-
ting operation is dusty. Everyday
eyeglasses only have impact resis-
tant 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.
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.
15. MAINTAIN TOOLS WITH CARE.
Keep tools lubricated and clean
for best and safest performance.
Follow instructions for lubricating
and changing accessories.
16. REDUCE THE RISK OF
UNINTENTIONAL FIRING. Do not
carry tool with hand on trigger and
always disconnect from air when
not in use.
17. DISCONNECT TOOLS before ser-
vicing, changing accessories, or
moving to another location.
18. DO NOT OVERREACH. Keep
proper footing/balance at all times.
19. USE THE RECOMMENDED
ACCESSORIES. Consult owner’s
manual for recommended acces-
sories. The use of improper acces-
sories may cause risk of injury.
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.
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.
22. NEVER ALLOW UNTRAINED
USERS TO USE THIS TOOL
WHILE UNSUPERVISED.
23. IF YOU ARE UNSURE OF THE
INTENDED OPERATION, STOP
USING TOOL. Seek formal training
or research books or magazines
that specialize in pneumatic tools.

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, punctur-
ing 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.
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.
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.
Additional Safety Instructions for Nailers
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.
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 specialize
in pneumatic tools.
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, causing
serious personal injury.
8. COMPRESSED AIR RATING:
Do not connect the nailer to com-
pressed air that exceeds 120 PSI.
9. CHECK VALVE: Do not use a
check valve or any other fitting that
allows air to remain in the tool.

The Model H8230/H8231 is designed
to operate at 70-110 PSI using clean,
dry, regulated, compressed air. DO NOT
exceed the 120 PSI maximum operating
pressure for your model.
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.

A safety mechanism on the nose of the
nailer protects against accidental firing.
The nailer is designed to only fire when
the safety nose is depressed and the trig-
ger is pulled. The nailer should not fire
otherwise.
This nailer also features a trigger lock
switch as an additional way to prevent
accidental firing.
Before you use your nailer for the first time,
you MUST verify that the safety mecha-
nisms on the nailer are working properly;
otherwise, the risk of accidental injury will
be greatly increased.
The nailer must be connected to a prop-
erly regulated air source to perform these
safety checks.
Safety Check #1—Nose
Without pulling 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.
• If the nailer does not fire, then the
safety nose mechanism is working cor-
rectly.
• If the nailer does fire when you do this,
immediately disconnect the nailer from
the air supply and call Grizzly Technical
Support at [phone] for help.
Safety Check Safety Check #2—Trigger
Make sure the nose is not depressed,
point the nailer in a safe direction away
from yourself or bystanders, then pull the
trigger.
• If the nailer does not fire, then the trig-
ger 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 [phone] for help.
Safety Check #3—Trigger Lock
Rotate the trigger lock switch counter-
clockwise so the arrow points to the lock
icon on the nailer body. Make sure the
nose is not depressed, point the nailer
in a safe direction away from yourself or
bystanders, then try to pull the trigger.
• If the trigger is locked and the nailer
does not fire, then the trigger lock 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 [phone] for help.
The safety mechanisms are not fool-
proof. Never rely on these mecha-
nisms as an excuse to point the nailer
at yourself or any bystanders. Serious
injury may occur.

If you have not read the safety instruc-
tions in this manual, do not operate the
nailer.
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, unless your air
system uses a lubricator as described on
Page 6.
While operating your nailer, keep in mind
that nail deflection is a constant hazard.
Deflection is caused when grain irregu-
larities, 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.
Firing Nails
Figure 7. Example of nail deflection.
To fire a nail:
1. Connect the nailer to your air supply.
2. Depress the safety nose mechanism
flat against the work surface, and pull
the trigger.
3. Check the nail penetration depth.
— If the nail either went too far or not
far enough, then refer to Adjusting
Depth on Page 9.
Besides damaging your workpiece, deflec-
tion can cause injury if your free hand is
securing the workpiece in the location that
the nail deflects.
To reduce your risk of injury from nail
deflection, always make sure your free
hand and other body parts are positioned
out of the way of a potential path of a nail
before pulling the trigger.
During operation, this nailer can pro-
pel objects into the air and exhaust
concentrated bursts of air, causing
immediate eye damage. To reduce
your risk from these hazards, always
wear ANSI approved safety glasses
or a face shield.
In addition, this nailer discharges
at up to 85-90 decibels. To reduce
your risk of hearing loss from oper-
ating this nailer, always wear ANSI
approved ear protection.
Never point this nailer at yourself or
another person! Always pay attention
to the direction this nailer is pointed to
reduce the risk of serious injury.

H8230/H8231 15° Roofing Nailer -9-
The nailer is designed to fire one nail at a
time, or one after another, using the safety
nose mechanism—this is known as "bump
fire."
To operate your nailer in single fire
mode:
1. Depress the safety nose mechanism
against the workpiece.
2. Pull the trigger, then release the trigger
after the nail is driven.
To operate your nailer in bump fire
mode:
1. Pull the trigger and hold it back.
2. Press the safety nose mechanism
against your workpiece to fire a nail.
You can continue holding the trigger
back and firing the nailer in this manner
without releasing the trigger.
Single/Bump Fire
Operation
The Model H8230/H8231 features a depth
adjustment knob for controlling nail pen-
etration depth (Figures 8 & 9).
Adjusting Depth
Figure 8. H8230 depth adjustment knob.
The adjustment knob controls nail penetra-
tion by changing where the nose mecha-
nism stops when depressed. Moving the
nose mechanism out or extending it away
from the nailer decreases nail penetration
depth.
Determining the correct nail penetration
depth requires trial-and-error and may
change depending on the type of material
you are nailing.
Depth Adjustment Knob
Figure 9. H8231 depth adjustment knob.
Depth Adjustment Knob
Take care to lift the nailer from the
workpiece each time you fire a nail
when bump firing, or the nailer may
bounce acriss the workpiece and rap-
idly fire nails.

Replacing Pistons/O-
Rings
If you use your nailer on a daily basis,
replacement pistons are cheap insurance
against wasted down time and lost profits
in the event that a piston or piston shaft
wears out.
6. Open the nose cover as if to clear a
jammed nail.
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 wood dowel 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. (If using metal tools, be care-
ful not to scratch the discharge area
or cyclinder when removing the piston
shaft.)
9. Place a new O-ring on the new piston
and apply a thin film of the air tool oil on
the O-ring.
10. Insert the new piston in the cylinder.
Make sure that any 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 grooves on the
guide.
11. After the piston is inserted correctly,
close the magazine. Replace the rear
cap assembly and tighten the four cap
screws.
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 for component loca-
tions.
To replace a piston:
1. DISCONNECT NAILER FROM THE
AIR SUPPLY!
2. Remove all nails from the magazine
cartridge.
3. Remove the four cap screws on the
back of the nailer, near the exhaust
port.
4. Remove the cap.
5. The top of the piston should now be
visible inside the cylinder, which is
housed in the head of the nailer.
Always disconnect air from nailer
whenever servicing! During mainte-
nance, a nailer connected to air may
fire accidentally, causing serious
personal injury!

CLEANING & LUBRICATION
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.
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.
Lubricating
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
14) before every use, or after 2 hours of
continuous use.
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.
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!
