OPERATION
Instructions for Use
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
(fig. 8). Always operate the tool with
the side handle properly mounted.

WARNING: To reduce the risk of
serious personal injury, ALWAYS use

serious personal injury, ALWAYS hold
securely in anticipation of a sudden
reaction.
Proper hand position requires one hand on the side
