• Rushing the job or forcing the tool is dangerous. Han-
dle the tool carefully. Do not operate when under the
influence of alcohol, drugs or the like.
• General Tool Handling Guidelines:
1. Always assume that the tool contains fasteners.
2. Do not point the tool toward yourself or anyone
whether it contains fasteners or not.
3. Do not activate the tool unless the tool is placed
firmly against the workpiece.
4. Respect the tool as a working implement.
5. No horseplay.
6. Do not hold or carry the tool with a finger on the
trigger.
7. Do not load the tool with fasteners when any one of
the operating controls is activated.
8. Do not operate the tool with any power source other
than that specified in the tool operating/safety
instructions.
• An improperly functioning tool must not be used.
• Sparks sometimes fly when the tool is used. Do not use
the tool near volatile, flammable materials such as gas-
oline, thinner, paint, gas, adhesives, etc.; they will ignite
and explode, causing serious injury.
• The area should be sufficiently illuminated to assure
safe operations. The area should be clear and litter-
free. Be especially careful to maintain good footing and
balance.
• 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 levels within
prescribed limits. In certain cases, shutters should be
used to contain noise.
• Do not play with the contact element: it prevents acci-
dental 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, disconnected, altered, or not
working properly.
• Operate the tool within the specified air pressure of
0.98 – 2.26 MPa (9.8 – 22.6 bar) for safety and longer
tool life. Do not exceed the recommended max. operat-
ing pressure of 2.26 MPa (22.6 bar). The tool should
not be connected to a source whose pressure poten-
tially exceeds 3.39 MPa (33.9 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 recom-
mended allowable pressure (see SPECIFICATIONS).
• Never use the tool with other than compressed air. If
bottled gas (carbon dioxide, oxygen, nitrogen, hydro-
gen, 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.
• 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.
• Check walls, ceilings, floors, roofing and the like care-
fully 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 sym-
bol “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 constructions, 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, present-
ing 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 dan-
ger 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 bottom. You can per-
form 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 some-
one, 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 ejection 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 dan-
gerous.
• 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 some-
thing 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 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.
• Do not modify tool without authorization from
Makita.
• Ask Makita’s Authorized service centers for periodical
inspection of the tool.
