Removing the blower attachment
The blower is equipped with a commutation motor. The carbon brushes of this motor are subject
to runtime-dependent wear. Therefore they must be replaced regularly.
CAUTION!
Heat development due to worn carbon brushes.
If Fault 311 occurs, the device must be shut off. The carbon
brushes must be replaced, since otherwise high heat
development and damage to the blower will occur.
Information
If the carbon brushes are replaced once and the blower shuts
off again, then it must be replaced.
