Care And Maintenance - Hilti AG 125-A22 Mode D'emploi

7 Operation
WARNING
Wear personal protective equipment. Exposure to
noise can cause hearing loss.
WARNING
Test new cutting or grinding discs by allowing them
to run at maximum speed in a protected area for at
least 60 seconds.
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
Always use the side handle with the power tool (use
the hoop handle as an option).
CAUTION
Use clamps or a vice to hold the workpiece securely.
CAUTION
Working on the material may cause it to splinter. Wear
eye protection and protective gloves. Wear breathing
protection if no dust removal system is used. Splin-
tering material presents a risk of injury to the eyes and
body.
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.

8 Care and maintenance

CAUTION
Before beginning cleaning, remove the battery from
the power tool in order to prevent unintentional start-
ing.

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 tilting
the disc in the kerf when cutting. The disc or wheel
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.
7.1 Rough grinding
CAUTION
Never use abrasive cutting discs for grinding.
Best results are obtained when the disc maintains an
angle of 5° to 30° with the working surface when grinding.
Move the power tool to and fro while applying moderate
pressure. This will avoid overheating and discoloration of
the workpiece and ensure an even surface finish.
7.2 Cutting
When cutting, apply moderate feed pressure and do not
tilt the power tool or, respectively, the cutting disc (hold
at approx. 90° to the surface being cut). For best results,
start cutting at the smallest cross section when cutting
profiles and square tube.
7.3 On / off switch with switch-on interlock 11
The on / off switch with safety lock (switch-on interlock)
gives you full control of the switch function and avoids
unintentional restarting.

8.1 Care of the power tool
DANGER
Under extreme conditions, when used for working on
metal, conductive dust may accumulate inside the tool.
Push the safety lock (switch-on interlock) forward to
unlock the on / off switch and then press the switch
fully.
The safety lock (switch-on interlock) returns auto-
matically to the locked position when the on / off
switch is released.
