the lock button and rotate the change lever so that the

CAUTION:

• Do not rotate the change lever when the tool is running

• To avoid rapid wear on the mode change mechanism,

be sure that the change lever is always positively
located in one of the two or 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.
