8.1 Care of insert tools
Clean off dirt and dust deposits and protect your insert
tools from corrosion by wiping them with an oil-soaked
rag from time to time.
8.2 Changing the chuck
The quick-release chuck must be tightened to the spec-
ified torque of 68 Nm.
The key-type chuck must be tightened to the specified
torque of 37–47 Nm and secured with the retaining
screw (left-hand thread), inserted between the jaws of
the chuck. The retaining screw must be tightened to a
torque of 7–11 mm.
8.3 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 a syn-
thetic rubber material.
Never operate the tool when the ventilation slots are
blocked. Clean the ventilation slots carefully with a dry
brush. Do not permit foreign objects to enter the inte-
rior of the tool. Clean the outside of the tool at regular
intervals with 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
containing silicone.
8.4 Maintenance
Check all external parts of the tool for damage at reg-
ular intervals and check that all controls operate fault-
lessly. Do not operate the tool if parts are damaged or
when the controls do not function faultlessly. If nec-
essary, your electric tool should be repaired at a Hilti
repair center.
Repairs to the electrical section of the tool may be car-
ried out only by trained electrical specialists.
8.5 Checks after care and maintenance
After carrying out care and maintenance on the tool,
check that all protective equipment has been refitted
and that all parts function faultlessly (side handle, chuck
tightened to specified torque).
