Maintenance - Makita AT638A Instruction Manual

CAUTION:
Do not place the contact element
against the workpiece with excessive force. Also,
pull the trigger fully and hold it on for 1-2 seconds
after stapling.
Even in the "Single sequential actuation" mode, half-
pulled trigger causes an unexpected stapling, when
the contact element re-contacts the workpiece.
Contact actuation
Pull the trigger first and then place the contact element
against the workpiece.

strip of staples. Failure to do so causes poor staple
feeding.

MAINTENANCE

CAUTION:
Before attempting to perform
inspection or maintenance, always return the trig-
ger and disconnect the air hose from the tool.
NOTICE:
Never use gasoline, benzine, thinner,
alcohol or the like. Discoloration, deformation or
cracks may result.
Staples
Handle staple strips and their box carefully. If the staple
strips have been handled roughly, they may be out of
shape, causing poor staple feed.
Avoid storing staples in a very humid or hot place or
place exposed to direct sunlight.
Maintenance of stapler
Always check the tool for its overall condition and loose
screws before operation. Tighten as required.
With tool disconnected, make daily inspection to assure
free movement of the contact element and trigger. Do
not use tool if the contact element or trigger sticks or
binds.
When the tool is not to be used for an extended period
of time, lubricate the tool using pneumatic tool oil and
store the tool in a safe place. Avoid exposure to direct
sunlight and/or humid or hot environment.
Maintenance of compressor, air set
and air hose
After operation, always drain the compressor tank and
the air filter. If moisture is allowed to enter the tool,
it may result in poor performance and possible tool
failure.
