Torque limiter
NOTICE:
As soon as the torque limiter actuates,
switch off the tool immediately. This will help pre-
vent premature wear of the tool.
NOTICE:
Drill bits such as hole saw, which tend
to pinch or catch easily in the hole, are not appro-
priate for this tool. This is because they will cause
the torque limiter to actuate too frequently.
The torque limiter will actuate when a certain torque
level is reached. The motor will disengage from the
output shaft. When this happens, the drill bit will stop
turning.
Hook
CAUTION:
Never hook the tool at high loca-
tion or on potentially unstable surface.

► Fig.17: 1. Action mode changing knob
Rotate the action mode changing knob to the
bol. Then make sure that the chisel is securely held in
place by turning it slightly.
Depth gauge
The depth gauge is convenient for drilling holes of
uniform depth. Loosen the side grip and insert the depth
gauge into the hole on the side grip. Adjust the depth
gauge to the desired depth and tighten the side grip
firmly.
