DO NOT
let children come into contact with the
tool. Supervision is required when inexperienced
operators use this tool.

(including children) suffering from diminished
physical, sensory or mental abilities; lack of
experience, knowledge or skills unless they are

Torque Limiting Clutch
All rotary hammerdrills are equipped with a torque
limiting clutch that reduces the maximum torque
reaction transmitted to the operator in case of
jamming of a drill bit. This feature also prevents the
gearing and electric motor from stalling. The torque
limiting clutch has been factory-set and cannot be
adjusted.
Electrical Safety
The electric motor has been designed for one
voltage only. Always check that the power supply
corresponds to the voltage on the rating plate.
