Check that all moving parts are undamaged and that
they function properly without sticking. All parts must
be fitted correctly and fulfill all of the conditions nec-
essary to ensure faultless operation.
Never place your hands in front of or on the saw blade.
Check the tool for possible damage. Protective devices
and any parts that may have suffered slight damage
should be checked for correct operation and func-
tionality before further use of the electric tool. Safety
devices or other parts that are found to be damaged
must be replaced or repaired properly by an autho-
rized repair workshop unless otherwise indicated in
the operating instructions.
5.3.1 Mechanical
Check that wrenches etc. have been removed from
the tool before switching it on.
Observe the instructions concerning care and main-
tenance and replacement of insert tools in good time.
Ensure that the insert tools used are equipped with the
correct connection end system and that they are prop-
erly fitted and secured in the chuck.
The safety guard for the saw blade must always be fit-
ted in order to prevent inadvertent contact with the
saw blade or the moving parts above the saw blade.
5.3.2 Electrical
Protect yourself against electric shock. Avoid body
contact with earthed / grounded objects, e.g. pipes
and radiators etc.
Check the condition of the tool’s supply cord at reg-
ular intervals. The supply cord should be replaced by
a trained electrical specialist if damage is found. Also
regularly check the condition of extension cords and
replace these if damage is found.
Check the condition of the tool. Do not operate the tool
if it is found to be damaged, if it is not complete or if
its controls cannot be operated faultlessly.
Do not touch the supply cord in the event of it suffer-
ing damage while working. Disconnect the supply cord
plug from the socket.
Damaged switches must be replaced at a Hilti service
center. Do not use the tool if it cannot be switched off
and on properly.
The tool should be repaired only by a trained electri-
cal specialist (Hilti service center using original Hilti
spare parts. Failure to observe this point may result
in a risk of accident to the user.
Do not use the supply cord for purposes for which it
is not intended. Never carry the tool by the supply
cord. Do not pull the plug out of the socket by pulling
the supply cord.
Do not expose the supply cord to heat, oil or sharp
edges.

approved and correspondingly marked as suitable for

In the event of a power cut: Switch off and unplug the
tool.
Avoid using extension cords with multiple sockets
and the simultaneous use of several electric tools con-
nected to one extension cord.
Never operate the tool when it is dirty or wet. Dust or
dampness on the surface of the tool make it difficult

regularly at a Hilti service center if it is used frequently
for cutting conductive materials.
