For chipping, scaling or demolition operations, depress
the lock button and rotate the action mode changing
knob to the
symbol. Use a bull point, cold chisel,
scaling chisel, etc.
CAUTION:
•
Do not rotate the action mode changing knob when
the tool is running under load. The tool will be
damaged.
•
To avoid rapid wear on the mode change
mechanism, be sure that the action mode
changing knob is always positively located in one
of the three action mode positions.
Torque limiter
The torque limiter will actuate when a certain torque
level is reached. The motor will disengage from the
output shaft. When this happens, the bit will stop turning.
CAUTION:
•
As soon as the torque limiter actuates, switch off
the tool immediately. This will help prevent
premature wear of the tool.
•
Bits such as hole saw, which tend to pintch or
catch easily in the hole, are not appropriate for this
tool. This is because they will cause the torque
limiter to actuate too frequently.
