H7664 2-in-1 Combination Nailer/Stapler
Additional Safety Instructions for Nailers and
Staplers
1. HAND INJURIES: Do not place
your hands near the nail/staple point
of entry. A nail/staple 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/stapler to pres-
surized oxygen or other combustible
gases as a power source. Only use
filtered, lubricated, and regulated
compressed air.
6. OPERATING QUESTIONS: If you
are not sure about the intended
operation, stop using the nailer/
stapler. Seek formal training or
research books or magazines that
specialize in pneumatic tools.
3. SAFE HANDLING: Never point
the nailer/stapler at others! Do not
keep the trigger pulled when loading
fasteners, carrying, or holding tool.
Carry the nailer/stapler only by the
handle, never by any other part. Do
not carry the nailer/stapler by the air
hose. Disconnect the nailer/stapler
from the air hose when going up and
down ladders.
7. MAINTENANCE: Always discon-
nect air from the nailer/stapler
when servicing or installing nails
or staples. During maintenance, a
nailer/stapler connected to air may
fire accidentally, causing serious
personal injury.
8. COMPRESSED AIR RATING: Do
not connect the nailer/stapler to
compressed air that exceeds 120
PSI.
4. CLEANING: Never use gasoline or
other flammable liquids to clean the
nailer/stapler; vapors in the nailer/
stapler 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.

H7664 2-in-1 Combination Nailer/Stapler
Compressed Air
System
The Model H7664 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/stapler, reg-
ulate the air pressure on your air compres-
sor to the minimum PSI for your model.
Exceeding the maximum permissible
operating pressure may cause the
nailer/stapler to explode, blowing
metal fragments in all directions. To
protect yourself from serious per-
sonal injury, DO NOT allow your air
compressor to exceed the recom-
mended pressure when connected to
this nailer/stapler!
An in-line filter/lubricator/regulator unit,
depicted in Figure 2, can be installed and
should be located as close to the nailer/
stapler 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 on the nose of
the nailer/stapler acts as a safety device.
When the trigger is pressed, the nailer/
stapler will not fire until the safety yoke
mechanism is depressed.
— If the nailer/stapler does not fire,
then the safety yoke mechanism is
working correctly.
Before you use your nailer/stapler for the
first time, check the safety yoke mecha-
nism to ensure proper function. To do
this:
— If the stapler does fire when you
do this, immediately disconnect the
stapler from the air supply and call
Grizzly Technical Support at (570)
546-9663 for help.
1. DISCONNECT NAILER/STAPLER
FROM THE AIR SUPPLY!
— If the stapler fires when the trig-
ger is pulled, without the safety
yoke mechanism being depressed,
disconnect the stapler from the air
supply and call Grizzly Technical
Support at (570) 546-9663 for help.
2. Make sure the magazine is empty and
contains no nails/staples.
3. Make sure the trigger and the safety
yoke mechanism move up and down
without sticking.
— If the stapler is not working properly,
check the lubrication of the sliding
mechanisms of the safety yoke.
4. Connect the nailer/stapler 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/stapler at yourself
or any bystanders. Serious injury may
occur.

To load your nailer/stapler:
4. Slide the staples or brads all the way
down to the nose of the nailer/stapler.
1. DISCONNECT NAILER/STAPLER
FROM THE AIR SUPPLY!
5. Push the magazine toward the nose of
the nailer/stapler until the catch lever
locks.
2. Grip the nailer/stapler firmly, unlatch
the catch lever (Figure 3), and pull the
magazine pusher back completely.
6. Reload the nailer when the magazine
sight window (Figure 4) shows the nail
or staple level is low. The sight window
shows up to approximately 50 nails or
staples loaded.
Operating
If you have not read the safety instruc-
tions in this manual, do not operate the
nailer/stapler.
Figure 3. Catch lever engaged and
magazine pusher retracted.
3. Insert a strip of brads or staples, point-
ed-end down, into the magazine as
shown in Figure 4.
Before you operate your nailer/stapler,
place two to three drops of the included
oil into the quick connect fitting where the
nailer/stapler connects to the air supply.
To operate your nailer/stapler:
1. Connect the air supply to the quick
connect fitting.
-12-

2. To test for proper nail/staple penetra-
tion, hold the nailer/stapler perpen-
dicular to the surface of a piece of
clean scrap wood that is thick enough
for the length of nails/staples you have
loaded.
Adjusting Depth
A depth adjustment knob is attached to the
nose for setting the nail/staple depth.
To adjust the depth:
3. Depress the safety yoke mechanism
on your workpiece.
1. DISCONNECT NAILER/STAPLER
FROM THE AIR SUPPLY!
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/staple in case
of deflection.
2. Rotate the adjustment knob (Figure
6) clockwise to drive the nails/staples
deeper or counterclockwise to drive the
nails/staples shallower.
Deflection is caused when grain
irregularities, knots or foreign objects
inside the wood cause the nail/staple
to change its path, resulting in the
nail/staple puncturing the surface of
the workpiece, as shown in Figure 5.
Adjustment Knob
Besides damaging your workpiece,
deflection can cause injury if your free
hand is securing the workpiece in the
location that the nail/staple deflects.
Figure 6. Rotating depth adjustment
knob.
3. Connect nailer/stapler to the air sup-
ply and test the nail/staple depth, and
repeat this entire procedure if neces-
sary until the nail/staple depth is satis-
factory.
Figure 5. Example of nail deflection.
5. Pull the trigger.
— If the nail/staple drove into the wood
far enough, continue with your
intended operations.
— If the nail/staple either went too far
or not far enough, then go to the
Adjusting Depth sub-section on
this page.

charge area:
Replacing Pistons/O-
Rings
1. DISCONNECT NAILER/STAPLER
FROM THE AIR SUPPLY!
If you use your nailer/stapler day in and
day out, repair pistons are cheap insur-
ance against wasted down time and lost
profits, in the event that a piston or piston
shaft becomes worn out. A replacement
piston and O-ring kit, part PH7664084,
may be purchased for the Model H7664.
2. Unlock the catch lever and pull the
magazine pusher back completely.
3. Remove the nail/staple stick from the
magazine.
4. Loosen the cap screws shown in
Figure 7 and remove the cover with
a 3mm hex wrench. Dislodge the
jammed nail/staple with a pair of nee-
dle nose pliers.
5. Secure the cover with the cap screws
removed in Step 4.
Cap Screws
Always disconnect air from nailer/
stapler whenever servicing! During
maintenance, a nailer/stapler con-
nected to air may fire accidentally,
causing serious personal injury!

head of the nailer/stapler, near the
exhaust port.
8. Slide the magazine pusher forward
to the front of the magazine until the
catch lever locks.
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/sta-
pler.
-15-
H7664 2-in-1 Combination Nailer/Stapler
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.
6. Open the nose cover as if to clear a
jammed nail/staple.
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/stapler
until you can grip the piston head and
remove it from the cylinder. (Be care-
ful not to scratch the discharge area
when pushing the piston shaft with the
screwdriver.)
11. After the piston is inserted correctly,
close the magazine pusher. Replace
the rear cap assembly and tighten the
4 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.
9. Place a new O-ring on the new piston
and apply a thin film of the nailer/sta-
pler lubricating oil on the O-ring.

H7664 2-in-1 Combination Nailer/Stapler
SECTION 5: MAINTENANCE
Lubricating
Cleaning
Disconnect the nailer/stapler from the
air supply before cleaning. Use a good
solvent to clean the nose assembly of
the nailer/stapler. Always be sure that the
nailer/stapler is dry before using it again.
Pneumatic tool oil has been included with
your new Grizzly nailer/stapler to help
maintain its useful life. Place two to three
drops of oil in the nailer/stapler air inlet (as
shown in Figure 8) 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/stapler; this may result in leaks and
damage to the nailer/stapler and the air
couplings.
Wipe off any excess oil near the nail-
er/stapler exhaust to avoid dust build-
up. When the oil that was included with
the nailer/stapler 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/stapler will not be necessary.
Just make sure there is always oil in the
lubricator.
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!
