3.3.1 PIN and PUK input
The appliance can only be start-
ed by entering a PIN (Personal
Identification Number). This pre-
vents the appliance from being
switched on by unauthorised
persons. The factory setting of
the PIN is 0000. The PIN can
be changed, see see chapter 5.2
"Making the basic settings",
page52.
If the PIN is entered incorrectly 3
times, the PUK (Personal Un-
locking Key) must be entered. If
this is also entered incorrectly,
the user must wait 24 hours until
entering it again.
The PIN and PUK input also
serves as an anti-theft device:
■
Keep the PIN and PUK so
that they are inaccessible to
unauthorised persons.
3.3.2 Sensors
The appliance is provided with
several safety sensors. It does
not restart automatically after be-
ing switched off by a safety sen-
sor. The error message is shown
on the display and must be ac-
knowledged. The reason for the
triggering of the sensor must be
resolved.
Lifting sensor
If the appliance is raised by the
housing during operation, the
travel drive switches off and the
cutting blades are stopped.
Bump sensors for obstacle
detection
The appliance is equipped with
sensors that ensure it changes
its direction of travel if it encoun-
ters obstacles. When it encoun-
ters an obstacle, the top part of
the deck is shifted slightly and
the shock sensor triggered.
