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.
Hole saws cannot be used with this tool. They tend
•
to pinch or catch easily in the hole. This 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.
