Diamond discs must be replaced when their cutting or grinding performance drops significantly. This
generally is the case when the segments reach a height of less than 2 mm.
Other discs must be replaced when their cutting performance drops significantly or other parts of the
angle grinder (not the disc) come into contact with the material you are working on.
Abrasive discs must be replaced when their expiry date has been reached.

Risk of injury. The accessory tool may work loose due to the braking effect of the motor.
▶ Wait until the accessory tool has come to a standstill before touching or gripping the accessory tool or
the clamping nut.
▶ Secure the accessory tool by tightening the clamping flange and clamping nut firmly so that no parts
work loose from the spindle due to the braking effect of the motor.
1. Clean the clamping flange and the clamping nut.
2. Check that the O-ring is in place in the clamping flange and that it is undamaged.
▶ Replace the O-ring if it is missing or damaged.
