11. Do not play with the contact element: it
prevents accidental discharge, so it must be
kept on and not removed. Securing the trigger
in the ON position is also very dangerous.
Never attempt to fasten the trigger. Do not
operate a tool if any portion of the tool

12. Operate the tool within the specified air
pressure on the tool label for safety and
longer tool life.
recommended max. operating pressure. The
tool should not be connected to a source
whose pressure potentially exceeds 480 PSIG
(3.39 MPa).
13. Never use the
compressed air. If bottled gas (carbon dioxide,
oxygen, nitrogen, hydrogen, air, etc.) or
combustible
acetylene, etc.) is used as a power source for
this tool, the tool will explode and cause
serious injury.
14. Always check the tool for its overall condition
and loose screws before operation. Tighten as
required.
15. Make sure all safety systems are in working
order before operation. The tool must not
operate if only the trigger is pulled or if only
the contact element is pressed against the
wood. It must work only when both actions
are performed.
operation with pins unloaded and the contact
element in fully pulled position.
16. Make sure that the trigger is locked when the
change lever is set to the LOCK position.
17. Check walls, ceilings, floors, roofing and the
like carefully to avoid possible electrical
shock, gas leakage, explosions, etc. caused
by striking live wires, conduits or gas pipes.
18. Use only pins specified in this manual. The
use of any other pins may cause malfunction
of the tool.
19. Do not permit those uninstructed to use the
tool.
20. Make sure no one is nearby before driving
pins. Never attempt to drive pins from both
the inside and outside at the same time. Pins
may rip through and/or fly off, presenting a
grave danger.
21. Watch your footing and maintain your balance
with the tool. Make sure there is no one below
when working in high locations, and secure
the air hose to prevent danger if there is

perpendicular surface, drive pins from the top
to the bottom. You can perform pin driving
operations with less fatigue by doing so.
23. A pin will be bent or the tool can become
jammed if you mistakenly drive pins on top of
another pin or strike a knot in the wood. The
the pin may be thrown and hit someone, or the
tool itself can react dangerously. Place the
pins with care.
24. Do not leave the loaded tool or the air
compressor under pressure for a long time
than out in the sun. Be sure that dust, sand, chips
and foreign matter will not enter the tool in the
place where you leave it setting.
propane, 25. Do not point the ejection port at anyone in the
vicinity. Keep hands and feet away from the
ejection port area.
26. When the air hose is connected, do not carry
the tool with your finger on the trigger or hand
it to someone in this condition. Accidental
firing can be extremely dangerous.
27. Handle the tool carefully, as there is high
pressure
dangerous if a crack is caused by rough
handling (dropping or striking). Do not
attempt to carve or engrave on the tool.

notice something wrong or out of the ordinary
with the tool.
29. Always disconnect the air hose and remove
all of the pins:

(10) Before performing any maintenance or
(11) Before cleaning a jam.
(12) Before moving the tool to a new location.
30. Perform cleaning and maintenance right after
finishing the job. Keep the tool in tip-top
condition. Lubricate moving parts to prevent
rusting and minimize friction-related wear.
Wipe off all dust from the parts.
31. When not operating the tool, always lock the
trigger by turning the change lever to the
LOCK position.
32. Do not modify tool without authorization from
Makita.
33. Do not attempt to keep the trigger or contact
element depressed with tape or wire. Death or
serious injury may occur.
