(Notes On Air Body Control - AH32.22-P-1000-03LWO)

Model 238, 257, 290

with code 489 (AIR BODY CONTROL)

NOTE:

The pressure in the components or in the overall system may not be relieved by detaching or disconnection of pressure lines. The pressure may only be relieved using a diagnostic system.
The area of the pressure line connections must be cleaned before starting the repair. Cleaning agents or solvents may not be used here.
Open pressure lines and pressure line connections must always be sealed.
For attaching and detaching pressure lines, only flare nut wrenches or special tools may be used.
Removed or slackened off suspension struts and air springs may not be filled with compressed air or pushed together; irreparable damage may be caused otherwise.
The suspension struts and air springs must not be twisted. Twisting results in the formation of folds and thus in the destruction of the suspension struts and air springs.
Observe the proper filling procedure when filling the suspension struts and air springs.
The suspension struts and air springs must not be loaded through spring movements between installation of the suspension struts and air springs and filling of the system.
Before driving through washer systems, pits and vehicle lifts or lanes with irregularities the vehicle level has to be raised.
The front wheels must be moved to the straight-ahead position when the vehicle is idle for extended periods. Otherwise, the body or the front fender may be damaged in event of pressure loss.
The leaflet regarding the new suspension struts and air springs and the expiration date must be observed.
