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.

ASSEMBLY

CAUTION:
Always be sure that the tool is switched off and
•
unplugged before carrying out any work on the
tool.
