Clean off dirt and dust deposits adhering to the blades
and protect them from corrosion by wiping from time to
time with an oil-soaked rag.
7.2 Care of the power tool
CAUTION
Keep the power tool, especially its grip surfaces,
clean and free from oil and grease. Do not use clean-
ing agents which contain silicone.
The outer casing of the power tool is made from impact-
resistant plastic. Sections of the grip are made from a
synthetic rubber material.
Never operate the power tool when the ventilation slots
are blocked. Clean 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.
