Torque limiter
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 pinch 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.
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.
