recommended max. operating pressure. The
tool should not be connected to a source
whose pressure potentially exceeds 14.0
2
kgf/cm G (200 PSIG).
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. Test for possible faulty operation
with nails unloaded and the contact element in
fully pulled position.
16. 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.
17. Use only nails specified in this manual. The
use of any other nails may cause malfunction
of the tool.
18. Do not permit those uninstructed to use the
tool.
19. Make sure no one is nearby before nailing.
Never attempt to nail from both the inside and
outside at the same time. Nails may rip
through and/or fly off, presenting a grave
danger.
20. 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
sudden jerking or catching.
21. On rooftops and other high locations, nail as
you move forward. It is easy to lose your
footing if you nail while inching backward.
When nailing against perpendicular surface,
nail from the top to the bottom. You can
perform nailing operations with less fatigue by
doing so.
22. A nail will be bent or the tool can become
jammed if you mistakenly nail on top of
another nail or strike a knot in the wood. The
nail may be thrown and hit someone, or the
tool itself can react dangerously. Place the
nails with care.

23. Do not leave the loaded tool or the air
compressor under pressure for a long time
out in the sun. Be sure that dust, sand, chips
and foreign matter will not enter the tool in the
than place where you leave it setting.
24. Do not point the ejection port at anyone in the
vicinity. Keep hands and feet away from the
propane, ejection port area.
25. 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.
26. Handle the tool carefully, as there is high
pressure inside the tool that can be dangerous
if a crack is caused by rough handling
(dropping or striking). Do not attempt to carve
or engrave on the tool.
27. Stop nailing operations immediately if you
notice something wrong or out of the ordinary
with the tool.
28. Always disconnect the air hose and remove all
of the nails:
(9)
(10) Before performing any maintenance or
(11) Before cleaning a jam.
(12) Before moving the tool to a new location.
29. 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.
30. Do not modify tool without authorization from
Makita.
31. Do not attempt to keep the trigger or contact
element depressed with tape or wire. Death or
serious injury may occur.
32. Always check contact element as instructed in
this manual. Nails may be driven accidentally
if the safety mechanism is not working
correctly.
33. Ask Makita's Authorized service centers for
periodical inspection of the tool.
34. To maintain product SAFETY and RELIABILITY,
maintenance and repairs should be performed
by Makita Authorized or Factory Service
Centers, always using Makita replacement
parts.
