• Only those involved in the work should be in the
vicinity. Children especially must be kept away at
all times.
• There may be local regulations concerning noise
which must be complied with by keeping noise lev-
els within prescribed limits. In certain cases, shut-
ters should be used to contain noise.
• 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 operating controls is inoperable, discon-
nected, altered, or not working properly.
• Operate the tool within the specified air pressure of
0.44 - 0.83 MPa (4.4 - 8.3 bar) for safety and longer
tool life. Do not exceed the recommended max.
operating pressure of 0.83 MPa (8.3 bar). The tool
should not be connected to a source whose pres-
sure potentially exceeds 1.37 MPa (13.7 bar).
• Make sure that the pressure supplied by the com-
pressed air system does not exceed the maximum
allowable pressure of the fastener driving tool. Set
the air pressure initially to the lower value of the
recommended allowable pressure (see SPECIFICA-
TIONS).
• Never use the tool with other than compressed air.
If bottled gas (carbon dioxide, oxygen, nitrogen,
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 seri-
ous injury.
• Always check the tool for its overall condition and
loose screws before operation. Tighten as
required.
• 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 arm is
pressed against the wood. It must work only when
both actions are performed. Test for possible faulty
operation with nails unloaded and the pusher in
fully pulled position.
• Make sure that the trigger is locked when the
change lever is set to the LOCK position.
• 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.
• Use only nails specified in this manual. The use of
any other nails may cause malfunction of the tool.
• Never use fastener driving tools marked with the
symbol "Do not use on scaffoldings, ladders" for
specific application for example:
- when changing one driving location to
another involves the use of scaffoldings,
stairs, ladders, or ladder alike construc-
tions, e.g. roof laths;
- closing boxes or crates;
- fitting transportation safety systems e.g. on
vehicles and wagons.
• Do not permit those uninstructed to use the tool.
• 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.
• 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.
• 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 bot-
tom. You can perform nailing operations with less
fatigue by doing so.
• 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.
• 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 place where you leave it
setting.
• Do not point the ejection port at anyone in the
vicinity. Keep hands and feet away from the ejec-
tion port area.
• 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.
• 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.
• Stop nailing operations immediately if you notice
something wrong or out of the ordinary with the
tool.
• 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.
• Perform cleaning and maintenance right after fin-
ishing the job. Keep the tool in tip-top condition.
Lubricate moving parts to prevent rusting and min-
imize friction-related wear. Wipe off all dust from
the parts.
• When not operating the tool, always lock the trig-
ger by turning the change lever to the LOCK posi-
tion.
• Do not operate this tool if it does not contain a legi-
ble WARNING LABEL.
• Do not modify tool without authorization from Mak-
ita.
• Ask Makita's Authorized service centers for period-
ical inspection of the tool.
• To maintain product SAFETY and RELIABILITY,
maintenance and repairs should be performed by
