Instructions for Use
WARNING:
• Always observe the safety instructions
and applicable regulations.
• Be aware of the location of pipework
and wiring.

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. 7). Always operate the tool with
the side handle properly mounted.
