▶ When operating an electric appliance outdoors, use only extension cords of a type suitable for outdoor
use. Use of an extension cord suitable for outdoor use reduces the risk of electric shock.
▶ In the event of an interruption in the electric supply, switch the appliance off and unplug it from the power
outlet.
▶ Use the power outlet on the appliance only for the purposes described in the operating instructions.
▶ Never operate the appliance when it is dirty or wet. Dust (especially dust from conductive materials) or
dampness adhering to the surface of the appliance may, under unfavorable conditions, lead to electric
shock. Dirty or dusty appliances should thus be checked by Hilti Service at regular intervals, especially
if used frequently for working on conductive materials.
