The purpose of safety symbols is to attract your attention to possible hazard-
ous conditions. This manual uses a series of symbols and signal words which
are intended to convey the level of importance of the safety messages. The
progression of symbols is described below. Remember that safety messages by
themselves do not eliminate danger and are not a substitute for proper accident
prevention measures.

not avoided, MAY result in minor or moderate injury.
It may also be used to alert against unsafe practices.
Indicates a potentially hazardous situation which, if
not avoided, COULD result in death or serious injury.

not avoided, WILL result in death or serious injury.
This symbol is used to alert the user to useful infor-

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 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 special-
ize 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, 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
check valve or any other fitting that
allows air to remain in the tool.

Failure to do so could result in seri-
ous personal injury, damage to
equipment or poor work results.

Compressed Air
System
The Model H6145 is designed to be oper-
ated at 70-120 PSI using clean, dry, regu-
lated, compressed air. DO NOT exceed
the maximum operating pressure 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.

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!
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.

Safety Yoke
A safety yoke mechanism (bump fire) on
the nose of the nailer acts as a second-
ary safety device. When the trigger is
pressed, the nailer will not fire until the
safety yoke mechanism is depressed.
Before you use your nailer for the first
time, check the safety yoke mechanism to
ensure proper function. To do this:
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
yoke mechanism move up and down
without sticking.
4. Connect the nailer to the air supply.
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.
— If the nailer does not fire, then the
safety yoke 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.
— If the nailer fires when the trigger
is pulled, without the safety yoke
mechanism being depressed, then
the nailer is not working properly.
— If either of these two conditions
develop after you have used your
nailer for a period of time, check the
lubrication of these mechanisms.
The safety yoke is a mechanical
device that can fail. Never rely on the
safety yoke 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.
4. Slide the nails all the way down to the
nose of the nailer.
5. Release the catch lever. The pusher
slides forward until it rests against the
nail stick.
