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. 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.
4. OPERATING QUESTIONS: If you

Compressed Air
System
The Model H6141 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.

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!

OPERATIONS
General Operations
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. Hold the nail firmly in place with one
hand as if using a regular hammer.
3. Make sure you are positioned out of
the way of a potential path of a nail in
case of deflection.
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 3.
4. Place the tip of the palm nailer over
the end of the nail. When the ram pin
touches the nail head, it will automati-
cally begin to hammer the nail into the
workpiece. Hold the nailer in place
until the sliding depth guide is fully
depressed.
5. You can stop the nailer at any time by
simply lifting it away from the nail and
workpiece. This is useful if you do not
wish for the nail to be countersunk into
the workpiece.
5. When the nail is fully hammered into
the workpiece, the nailer will automati-
cally stop.
Note: The air palm nailer will automati-
cally countersink all nails to a depth of
around 2mm or 5⁄64".
Figure 3. Example of nail deflection.
Operation of this nailer has the poten-
tial to propel debris into the air which
can cause eye injury. Always wear
ANSI-approved safety glasses or gog-
gles when operating equipment.

Replacing Pistons/O-
Rings
If you use your nailer day in and day out,
replacement pistons are cheap insurance
against wasted down time and lost profits,
in the event that a piston or piston shaft
becomes worn out.
6. Push the ram pin towards the inside of
the nailer. This will push the cylinder
free of the housing.
7. Remove the piston from the cylinder
by pulling it free by the ram pin.
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.
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 inside the
cylinder.
10. After the piston is inserted correctly,
place the cylinder back in the housing.
If seated correctly, the cylinder will
snap into place.
11. Push the cylinder collar down into
the housing as far as it will go. The
horizontal air slots on the side of the
cylinder should be visible.
12. Replace the rear cap assembly and
tighten the four cap screws.
13. Replace the flat washer, compression
spring, depth guide and nose piece
and tighten using a 19mm wrench.
14. 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. Unscrew the nose piece with a 19mm
wrench.
3. Remove the nose piece, depth guide,
compression spring and flat washer.
4. Remove the four cap screws and
washers on the back of the nailer.
5. Remove the cap.
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
piece and depth guide 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 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
4) 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 manual lubri-
cation of your nailer will not be necessary.
Just make sure there is always oil in the
lubricator.
Figure 4. 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!
