7.1 TPS theft protection system (optional)
NOTE
The machine may be equipped with the optional theft
en
protection system. If the machine is equipped with this
feature it can be unlocked and made ready for operation
only with the corresponding TPS key.
7.1.1 Unlocking the machine
1. Check that the machine is connected to the electric
supply. The yellow theft protection indicator LED
blinks. The machine is now ready to receive the
signal from the TPS key.
2. Hold the TPS key or the TPS watch strap buckle
against the lock symbol. The machine 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 machine
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 machine.

cleaner for information about disposal of the material
collected.

To avoid electrostatic effects, use an anti-static vacuum
cleaner.

until the core bit has centered itself and then in-
crease the pressure. Drill to a depth of 3-5 mm to
form a guide kerf (optional operation).

switch and then wait until the core bit has stopped
rotating (optional operation).
