Installation - Makita AN621 Betriebsanleitung

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.
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
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 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
•
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.
When not operating the tool, always lock the
•
trigger by turning the change lever to the LOCK
position.
Do not modify tool without authorization from
•
Makita.
Ask Makita's Authorized service centers for
•
periodical inspection of the tool.
To maintain product SAFETY and RELIABILITY,
•
maintenance and repairs should be performed by
Makita Authorized Service Centers, always using
Makita replacement parts.
Use only pneumatic tool oil specified in this
•
manual.
Never connect tool to compressed air line where
•
the maximum allowable pressure of tool cannot be
exceeded by 10 %. Make sure that the pressure
supplied by the compressed 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.
Do not attempt to keep the trigger contact element
•
depressed with tape or wire. Death or serious
injury may occur.
Always check contact element as instructed in this
•
manual. Nails may be driven accidentally if the
safety mechanism is not working correctly.

The air compressor must comply with the requirements
of EN60335-2-34.
Select a compressor that has ample pressure and air
output to assure cost-efficient operation. The graph
shows the relation between nailing frequency, applicable
pressure and compressor air output.
Thus, for example, if nailing takes place at a rate of
approximately 50 times per minute at a compression of
0.59 MPa (5.9 bar), a compressor with an air output over
80 liters/minute is required.
Pressure regulators must be used to limit air pressure to
the rated pressure of the tool where air supply pressure
exceeds the tool's rated pressure. Failure to do so may
result in serious injury to tool operator or persons in the
vicinity.
