5.1 Additional handle (Fig. 2 – Item 6)
For safety reasons you must only use the
hammer drill with the additional handle.
The additional handle (6) enables you to achieve
better stability whilst using the hammer drill. The
machine must not be used without the additional
handle (6) for safety reasons.
The additional handle (6) is secured to the
hammer drill by a clamp. Turning the handle anti-

the clamp. Turning the handle clockwise will tigh-
ten the clamp.
First release the additional handle clamp. You can
then swing the additional handle (6) into the most
comfortable working position for you. Now turn
the additional handle in the opposite direction
again until the additional handle is secure.
