▶ Dirty or dusty power tools that have been used frequently for work on conductive materials should be
checked at regular intervals at a Hilti Service Center. Dust (especially dust from conductive materials) or
dampness adhering to the surface of the power tool may, under unfavorable conditions, lead to electric
shock.
▶ Switch the power tool off and unplug the supply cord in the event of a power failure or interruption in the
electric supply. This will prevent accidental restarting when the electric power returns.
