CLEANING AND MAINTANCE
Always pull out the mains power plug before starting any cleaning work. Cleaning
• Keep all safety devices, air vents and the motor housing free of dirt and dust as far as possible. Wipe the
equipment with a clean cloth or blow it with compressed air at low pressure.
• We recommend that you clean the device immediately each time you have finished using it.
• Clean the equipment regularly with a moist cloth and some soft soap. Do not use cleaning agents or
solvents; these could attack the plastic parts of the equipment. Ensure that no water can seep into the
device. Carbon brushes In case of excessive sparking, have the carbon brushes checked only by a qualified
electrician. Important! The carbon brushes should not be replaced by anyone but a qualified electrician.
Maintenance There are no parts inside the equipment which require additional maintenance.
ENVIRONMENT

- in observance of European Directive 2002/96/EC on waste of electric and electronic equipment and its
implementation in accordance with national law, electric tools that have reached the end of their life must
be collected separately and returned to an environmentally compatible recycling facility
