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.
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: 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.
6. OPERATING QUESTIONS: If you
are not sure about the intended
operation, stop using the nailer.
Seek formal training or research
sources that specialize in pneu-
matic 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, caus-
ing 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

when operating this nailer.
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.
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 H7665 is designed to be oper-
ated at 60–100 PSI using clean, dry, regu-
lated, compressed air. DO NOT exceed
the 120 PSI maximum operating pres-
sure for your model.
Before using your new nailer, regulate the
air pressure on your air compressor to the
minimum PSI 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.

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.
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!

H7665 21° Round Head Framing Nailer -7-
Testing the 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.
Before you use your nailer for the first
time, check the safety nose mechanism
to ensure proper function.
To verify that the safety nose is work-
ing correctly:
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.
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.
— 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.
6. Without depressing the safety nose
against a scrap piece of wood, point
the nailer in a safe direction, and pull
the trigger.
— If the nailer does not fire, then the
safety nose mechanism is working
correctly.
— If the nailer does fire when the trig-
ger is pulled, without the safety nose
mechanism being depressed, then
the nailer is not working properly,
call Grizzly Technical Support at
[phone] for help.
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.

Operating
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.
To operate your nailer:
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. Depress the safety nose mechanism
against your workpiece.
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 the next page.
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.
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.
Besides damaging your workpiece,
deflection can cause injury if your free
hand is securing the workpiece in the
location that the nail deflects.
Figure 5. Example of nail deflection.

A jammed nail must be cleared before
using the nailer again.
To clear a jammed nail from the dis-
charge area:
1. DISCONNECT NAILER FROM THE
AIR SUPPLY!
2. Pull the magazine handle all the way
back until it latches.
3. Remove the nail stick from the maga-
zine.
4. Locate the opening in the underside of
the nailer nose (Figure 7).
5. Dislodge the jammed nail with a tool
that will fit in the slot on the underside
of the nose, such as needle nose pli-
ers.
6. 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!

Replacing
Pistons/O-Rings
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.
The piston repair kit part number for the
Model H7665 is #PH7665095. For your
convenience, refer to the parts breakdown
during this procedure to identify parts and
their locations inside the nailer.
4. The top of the piston should now be
visible inside the cylinder, which is
housed in the head of the nailer.
5. Open the nose cover as if to clear a
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.
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.
10. After the piston is inserted correctly,
close the magazine. Replace the rear
cap assembly and tighten the 4 cap
screws.
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.
To replace a piston and O-ring(s):
1. DISCONNECT NAILER FROM THE
AIR SUPPLY!
2. Remove all nails from the magazine
cartridge.
3. Remove the four cap screws on the
head of the nailer, near the exhaust
port, and remove the cylinder cover.
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 dam-
age to the nailer and the air couplings.
Lubricating
Special 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 8) every 2 hours of con-
tinuous 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 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.
Figure 8. Lubricating nailer via air inlet.
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!
