CAUTION:
• To prevent excessive temperature
increase of the tool surface, do not
operate the tool continuously using
two or more battery packs. The tool
needs cool-off time before switching
to another pack.
• Do not close up vent holes on the
sides of the body during operation.
Otherwise, the machine function is
adversely affected to cause a failure.
• Do NOT strain the tool (motor). This
may cause damage to the unit.
• Use the tool in such a way as to
prevent the air from the body vent
holes from blowing directly onto
your skin. Otherwise, you may get
burned.
Bit-locking Function
1. With the trigger switch not engaged
and a screwdriver bit locked in
place, the tool can be used as a
manual screwdriver (up to 40 N•m,
408 k
g
f-cm, 353 in-lbs).
There will be a little play in the
chuck, but this is not a malfunction.
2.
This feature is handy for tightening
screws that require more torque
than the maximum torque of the
driver (position on the clutch), for
confirming the tightness of a screw or
to loosen an extremely tight screw.
