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 mech-
anism, 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 out-
put 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.
