Functional Description - Hilti WSJ 750-ET Operating Instructions Manual

Damaged switches must be replaced at a Hilti service
G
center.
In the event of a power cut: Switch off and unplug the

Avoid using extension cords with multiple sockets

and the simultaneous use of several electric tools con-
en
nected to one extension cord.
Never operate the tool when it is dirty or wet. Dust or
G
dampness on the surface of the tool make it difficult
to hold and, under unfavorable conditions, may lead
to electric shocks. Accordingly, have the tool checked
