Instructions for use
Always observe the safety instructions
and applicable regulations.
Be aware of the location of pipework and wiring.
Apply only a gentle pressure to the tool (approx. 5 kg).
Excessive force does not speed up drilling but
decreases tool performance and may shorten tool life.
Do not drill or drive too deep to prevent damage to
the dust cover.
Switching on and off (fig. A)
• To run the tool, press the variable speed switch
(1). The pressure exerted on the variable speed
switch determines the tool speed.
