WARNING:
•
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.
•
Always hold the tool firmly with both
hands and ensure a secure stance.
Always operate the tool with the side
handle properly mounted.
