NOTE
Adjust the position of the guard to suit the requirements
of the work being done.
DANGER
Wear ear protectors.
Exposure to noise can cause hear-
ing loss.
CAUTION
The closed side of the guard must always face the
operator.
WARNING
Test new cutting or grinding discs by allowing them
to run at maximum speed in a protected area for at
least 30 seconds.
WARNING
Do not use the power tool if it starts with a jolt.
This
may be an indication that the electronic control unit is
defective. Have the tool repaired at an authorized Hilti
service center right away.
WARNING
Slits cut in loadbearing walls of buildings or other struc-
tures may influence the statics of the structure, especially
when steel reinforcing bars or load-bearing components
are cut through.
Consult the structural engineer, ar-
chitect, or person in charge of the building project
before beginning the work.
WARNING
The electric supply voltage must comply with the in-
formation given on the type identification plate on the
power tool. 230 V power tools may also be connected
to a 220 V supply.
WARNING
Always use the side handle with the power tool.
CAUTION
Use clamps or a vice to hold the workpiece securely.
WARNING
Cutting or grinding may cause splintering of the material.
Wear eye protection.
CAUTION
Breathing protection must be worn if the power tool
is used without a dust removal system for work that
creates dust.
WARNING
Avoid touching rotating parts. Switch the power tool
on only after bringing it into position at the workpiece.
Touching rotating parts, especially rotating insert tools,
may lead to injury.
CAUTION
The insert tool may get hot during use.
Wear protective
gloves when changing insert tools.
WARNING
Reduce the load on the power tool by avoiding tilt-
ing the disc in the kerf when cutting.
The disc may
otherwise break, or the power tool may kick back or stall.
CAUTION
Improve the blood circulation in your fingers by re-
laxing your hands and exercising your fingers during
breaks between working.
WARNING
Keep inflammable materials away from the working
area.
