8.1 Care of insert tools
Clean off dirt and dust deposits adhering to the insert tools and
protect them from corrosion by wiping the insert tools from time
to time with an oil-soaked rag.
8.2 Care of the power tool
CAUTION
Keep the power tool, especially its grip surfaces, clean and
free from oil and grease. Do not use cleaning 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.
