Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control. In accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation. 5) Service a) Have your power tool serviced by a qualified repair person using only identical replacement parts. Do not touch the damaged cable and pull the mains plug when the cable is damaged while working.

Penetrating a water line causes property damage or may cause an electric shock.
