ADJUSTING THE LUMBAR SUPPORT
An upper and a lower air chamber are integrated
into the backrest. They can be inflated or deflated
independently of each other. The backrest convexity
can be adapted to the shape of the operator's spine
with the two push-buttons (12).
For both push-buttons:
- by pressing + the air chamber is inflated;
- by pressing - the air chamber is deflated.
SEAT HEATING
Two electric heating elements (seat and backrest)
are installed in the operator's seat.
The maximum heating capacity is preset. The tem-
perature is thermostat-controlled.
Switching on and off
This is done with a rocker switch (13) on the left side
of the backrest.
"0": heating OFF
"I": heating ON
The seat heating can be switched on only if the igni-
tion key is set to position "I" (Ignition ON).
BACKREST EXTENSION (OPTIONAL) (HEAD
SUPPORT)
The backrest extension can be suited individually in
height, by pulling the same out (14) up to stroke end
by means of a toothed rod.
Adjustment range: 100 mm (3.94 in) in 7 places
To remove the backrest extension, override the
resistance of the stroke end with a light pull.
