Selecting the action mode

Rotation with hammering

For drilling in concrete, masonry, etc., depress the lock but-
ton and rotate the change lever so that the pointer points to
the

symbol. Use a tungsten-carbide tipped bit.

Hammering only

For chipping, scaling or demolition operations, depress the
lock button and rotate the change lever so that the pointer
points to the

symbol. Use a bull point, cold chisel, scaling

chisel, etc.

CAUTION:

•

Do not rotate the change lever 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 change lever is always positively located in
one of the two 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.
