General instructions
The operating instructions must be read in full before use.
• • • •
The operating instructions must be kept in the vehicle and always be at hand.
• • • •
The driver's seat may only be fitted, serviced and repaired by specialist personnel
• • • •
– especially concerning the use of belt tensioners.
The respective national regulations and the vehicle manufacturer's fitting instructions must
be observed.
The national fitting regulations can be obtained from GRAMMER AG or from agencies of
the company, or from the vehicle manufacturer.
Worn parts such as rollers, shock absorbers and the fixation must be checked from time to
• • • •
time. If the driver's seat is not adjusted to the medium position in case of load, the system
pressure at the supply line or the function of the control valve for medium position
adjustment have to be checked.
A correctly functioning and individually adjusted driver's seat is essential to your health.
• • • •
Take adequate care of your seat and have it serviced regularly to ensure that it functions
correctly.
The functional checks are to be carried out at least as regularly as vehicle services
(see maintenance plan for vehicle).
These operating instructions should always be kept with the driver's seat. If the seat is
• • • •
passed on to a third party, it must be accompanied by the relevant operating instructions.
Subject to modifications serving engineering progress and deviations compared to the
• • • •
standard type seat arising therefrom.
Safety instructions
To prevent injury, no objects should be placed within the moving area of the driver's
• • • •
seat.
Before commissioning of the driver's seat, possible packaging material has to be
• • • •
removed from the seat cushion and the backrest upholstery.
To eliminate any risk of accident, the settings must be checked to ensure they are correctly
• • • •
engaged before the vehicle is driven.
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 AG parts) may impair the safety standard to which it has been tested.
Functions may be impaired, threatening your safety. For this reason, any change in
design of the seat must be approved by GRAMMER AG.
