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.
