OPERATION

Instructions for Use
WARNING: Always observe the safety
instructions and applicable regulations.
WARNING: To reduce the risk of serious
personal injury, turn tool off and disconnect
tool from power source before making
any adjustments or removing/installing
attachments or accessories.
WARNING: Tool bits may be hot and gloves
should be worn when changing or removing
them to avoid personal injury.
WARNING:
• Be aware of the location of pipework and
wiring.
• Apply only a gentle pressure to the tool
(approx. 20 kg). Excessive force does
not speed up drilling but decreases tool
performance and may shorten tool life.
• Always hold the tool firmly with both
hands and ensure a secure stance.
Always operate the tool with the side
handle properly assembled.
