portion of the tool operating controls is inopera-
ble, disconnected, altered, or not working prop-
erly.
12. Operate the tool within the specified air pressure
on the tool label for safety and longer tool life.
Do not exceed the 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 tool with other than compressed
air. If bottled gas (carbon dioxide, oxygen, nitro-
gen, hydrogen, air, etc.) or combustible gas
(hydrogen, propane, 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 oper-
ate if only the trigger is pulled or if only the con-
tact 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. 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 nails specified in this manual. The use
of any other nails may cause malfunction of the
tool.
19. Do not permit those uninstructed to use the tool.
20. 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.
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 sudden
jerking or catching.
22. 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 opera-
tions with less fatigue by doing so.
23. 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.
24. Do not leave the loaded tool or the air compres-
sor 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 place where you
leave it setting.
25. Do not point the ejection port at anyone in the
vicinity. Keep hands and feet away from the ejec-
tion 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 pres-
sure 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.
28. Stop nailing operations immediately if you
notice something wrong or out of the ordinary
with the tool.
29. Always disconnect the air hose and remove all of
the nails:
(1) When unattended.
(2) Before performing any maintenance or
repair.
(3) Before cleaning a jam.
(4) Before moving the tool to a new location.
30. Perform cleaning and maintenance right after
finishing the job. Keep the tool in tip-top condi-
tion. 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 trig-
ger 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 ele-
ment depressed with tape or wire. Death or seri-
ous injury may occur.
34. Always check contact element as instructed in
this manual. Nails may be driven accidentally if
the safety mechanism is not working correctly.
35. Ask Makita's Authorized service centers for peri-
odical inspection of the tool.
36. To maintain product SAFETY and RELIABILITY,
maintenance and repairs should be performed
by Makita Authorized or Factory Service Centers,
always using Makita replacement parts.
