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.

7.1 Working with the power tool

Take care to ensure that the closed side of the guard is
always positioned toward the operator's body.
Adjust the position of the guard (hood) to suit each cutting
application.
7.2 TPS theft protection system (optional)
NOTE
The power tool may be equipped with the optional theft
protection system. If the power tool is equipped with this
feature, it can be unlocked and made ready for operation
only with the corresponding TPS key.
7.2.1 Unlocking the power tool
1. Plug the supply cord into the power outlet. The
yellow theft protection indicator LED blinks. The
power tool is then ready to receive the signal from
the TPS key.
2. Hold the TPS key against the lock symbol. The
power tool is unlocked as soon as the yellow theft
protection indicator LED no longer lights.
NOTE If, for example, the electric supply is briefly
interrupted due to a power failure or disconnected
when moving to a different workplace, the power
tool remains ready for operation for approx. 20
minutes. In the event of a longer interruption, the
TPS key must be used again to unlock the power
tool.
7.2.2 Activation of the tool's theft protection
system
NOTE
Further detailed information on activation and use of the
theft protection system can be found in the operating
instructions for the theft protection system.
7.3 Switching on

7.5 Working with cutting discs
DANGER
To reduce the risk of kick-back, avoid bringing the
cutting tool into contact with the material in the area
indicated.
DANGER
Wherever possible, bring the wheels into contact with
the workpiece before starting the cut. Take extra care
in situations where this is not possible or where the
cutting disc is inserted in an existing cut.

3.
Reposition your thumb around the rear grip.
When cutting mineral materials, first bring the tool's
guide wheels into contact with the object to be cut.
Allow the power tool to reach full speed.
Apply pressure to the power tool so that the cutting
disc is pressed into the material slowly. This ensures
that particles and sparks generated by the cutting
operation are caught by the hood and extracted by
the dust removal system.
NOTE Apply moderate pressure, adjusting the rate
of advance to suit the material being cut.
NOTE The diamond disc may overheat and suffer
damage when cutting very hard mineral materials,
e.g. concrete with a high hard pebble content. A
trail of sparks right round the circumference of the
diamond cutting disc is a sure indication of this.
Should this occur, stop cutting and cool the disc by
allowing the tool to run under no load.
A drop in the rate of cutting progress can be an
indication of "blunt" (polished) diamond segments.
The segments can be resharpened by making a few
cuts in an abrasive material (Hilti sharpening plate
or sand-lime block).
