binding of moving parts, breakage of parts and
any other condition that may affect the power
tool's operation. If damaged, have the power tool
repaired before use. Many accidents are caused by

tive gloves.
5.3.2 Power tool use and care
a) Secure the workpiece. Use clamps or a vice to
secure the workpiece. The workpiece is thus held
more securely than by hand and both hands remain
free to operate the power tool.
b) Check that the insert tools used are compatible
with the chuck system and that they are secured
in the chuck correctly.
c) In the event of a power failure or interruption in the
electric supply, switch the power tool off, unplug
the supply cord and release the switch lockbutton
(if applicable). This will prevent accidental restarting
when the electric power returns.
5.3.3 Electrical safety
a) Before beginning work, check the working area
(e.g. using a metal detector) to ensure that no
concealed electric cables or gas and water pipes
are present. External metal parts of the power tool
may become live, for example, when an electric cable
is damaged accidentally. This presents a serious risk
of electric shock.
b) Check the power tool's supply cord at regular
intervals and have it replaced by a qualified spe-
cialist if found to be damaged. If the power tool's
supply cord is damaged it must be replaced with
a specially-prepared supply cord available from
Hilti Customer Service. Check extension cords
at regular intervals and replace them if found to
be damaged. Do not touch the supply cord or
extension cord if it is damaged while working.
