7.1 Care of insert tools
Clean off dirt and dust deposits and protect your insert
tools from corrosion by wiping them from time to time
with an oil-soaked rag.
7.2 Care of the electric tool
The outer casing of the tool is made from impact-resis-
tant plastic. Sections of the grip are made from an elas-
tomer material.
Never operate the tool when the ventilation slots are
blocked. Clean the ventilation slots carefully using a dry
brush. Do not permit foreign objects to enter the interior
of the tool. Clean the outside of the tool at regular intervals
using a slightly damp cloth. Do not use a spray, steam
pressure cleaning equipment or running water for cleaning.
This may negatively affect the electrical safety of the
tool. Always keep the grip surfaces of the tool free from
oil and grease. Do not use cleaning agents which contain
silicone.

ried out only by trained electrical specialists
