9 ADJUSTMENTS
Adjustments must not be made while driving
After removal of the backrest upholstery, the backrest frame must be supported, for example 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 changes to the series standard of the seat (for example fitting parts which are not original GRAMMER
parts) may impair the safety standard to which it has been tested.
Functions may be impaired, threatening your safety. For this reason, any changes in design of the seat must be
approved by GRAMMER.
During the removal and installation of the driver's seat, the corresponding instructions by the specific vehicle
manufacturer must be strictly observed!
Do not hold onto the covers for lifting the driver's seats. If you do so anyway, there is an increased risk of injury
due to loosening or breaking covers.
Before you remove the driver's seat, disconnect all plug-in connections between the seat and the vehicle supply
network. When you replace the plug-in connectors, make sure they are tight to prevent ingress of dust and
water.
Seatbelts must be fastened before driving. The seatbelt
must be replaced after an accident.
Where seatbelts are fitted to the driver's seat, the seat and
seat mounting must be checked additionally by specialist
personnel after an accident has occurred.
Fasteners must be checked regularly for a tight seat. If the
seat wobbles there may be loose bolts or other faults.
If you notice that the seat does not function correctly (for
example a defective seat suspension; improper curvature

of the lumbar support or damaged bellows), contact a
specialist workshop immediately to arrange for repairs to
be carried out.

– INCREASED RISK OF ACCIDENT –
Loads must not be placed on seats with a built in switch, except for the driver's weight during normal use, as the
vehicle may otherwise start to move by itself.
– INCREASED RISK OF ACCIDENT –
If you take off the weight from the seat while driving, this will cause the vehicle to stop.
Do not indent the bellows while there is load on the driver's seat.
– RISK OF CRUSHING –
Make sure that the interior of drivers seat remains free of foreign particles or liquids.
The driver's seat is not watertight and must be protected against splashes of water!
