oil and grease. Do not use cleaning agents which contain silicone.

the ventilation slots carefully using a dry brush. Do not permit foreign
objects to enter the interior of the power tool. Clean the outside of the
power tool at regular intervals with a slightly damp cloth. Do not use a spray,
steam pressure cleaning equipment or running water for cleaning. This may
negatively affect the electrical safety of the power tool.
