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. The ingress of water into
an electric tool increases the risk of an electric shock.
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. Lubricate
all moving parts at regular intervals.
Storage
Store the equipment and accessories out of children's reach in a dark and dry place at above freezing
temperature. The ideal storage temperature is between 5 and 30 °C. Store the electric tool in its original
packaging.
Do not dispose of electric tools, accessories and packaging together with household waste material
- 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
