8.1 Care of the product
DANGER
Electric shock due to breakdown of protective insulation. When working on metal under extreme
conditions, conductive dust may accumulate inside the power tool, thereby adversely affecting the
protective insulation.
▶ Use a stationary dust extraction system when working under extreme conditions.
▶ Clean the air vents frequently.
▶ Use a ground fault circuit interrupter (PRCD) in the electric power supply line to the power tool.
WARNING
Electrical hazards. Improper repairs to electrical parts may lead to serious injuries.
▶ Electrical parts may be repaired only by trained electrical specialists.
▶ Never operate the product when the air vents are blocked. Clean the air vents carefully using a dry brush.
Do not allow foreign objects to enter the interior of the product.
▶ Keep the product, especially its grip surfaces, clean and free from oil and grease. Do not use cleaning
agents containing silicone.
▶ Clean the outer surfaces of the tool with a slightly damp cloth at regular intervals. Do not use a spray,
steam pressure cleaning equipment or running water for cleaning.
Note
Frequent work on conductive materials (e.g. metal, carbon fiber) may make shorter maintenance
intervals necessary. Take your individual workplace risk assessment into account.

they function faultlessly.
