5.7 Driver's seat
Safety instructions:
To prevent damage to the driver’s back, the seat must be adjusted for the driver’s
weight before use and each time the drivers change.
To prevent injury, no objects should be placed within the moving area of the driver’s
seat.
To eliminate any risk of accident, the settings must be checked to ensure they are
correctly engaged before driving the vehicle.
Adjustments must not be made while operating or driving.
When the backrest upholstery has been removed, the backrest frame must be sup-
ported, e.g. held in place, before the backrest adjuster is operated. If you fail to do
so, there is a danger that the backrest frame may jerk forward and cause injury.
Any modification to the standard condition of the driver's seat (e.g. with other than
original retrofitting and spare parts made by Grammer) may invalidate the certified
and approved condition of the driver's seat. Functions may be impaired, threaten-
ing your safety. For this reason, any structural change to the driver‘s seat must be
approved by Grammer.
Fasteners must be checked regularly for tightness. If the seat wobbles there may
be loose bolts or other faults. If the seat does not function correctly (e.g. the seat
suspension), contact a specialist workshop immediately to arrange for repairs to be
carried out.
The driver’s seat may only be installed, maintained and repaired by specialist staff.
If you fail to do so, your health may be affected and the risk of accident increases.
Weight adjustment
The seat should be adjusted for the dri-
ver’s weight by briefly pulling the actu-
ator lever of the automatic weight and
height adjuster (arrow) with the vehicle
at a standstill and the driver sitting on the
seat.
The driver must sit absolutely still during
adjustment.
To prevent damage to health, the setting
for the driver’s weight must be checked
and adjusted as necessary before the
vehicle is driven.
Height adjustment
The seat height can be set pneumatically
and is infinitely adjustable.
The seat height can be altered by pulling
or pressing the actuator lever (arrow). If
the adjustment reaches the top or bottom
end stop, the height is adjusted automat-
ically in order to guarantee a minimum
spring travel.
In order to avoid damage, do not operate
compressor for more than 1 minute.
