Shown On Model 211 With Steel Suspension, Part 1:

DANGER:
- Lethal injuries are possible if vehicle slips off of lifting platform
- Align vehicle between the columns of the lifting platform and position the four support plates at the lifting platform support points specified by the vehicle manufacturer.
- Risk of injury Body parts may become jammed or crushed. Risk of injury Skin and eyes may be injured due to brake fluid spraying out at high pressure when working on the SBC brake system
- Deactivate SBC brake system using STAR DIAGNOSIS.

CAUTION:
- Before opening the SBC system, thoroughly clean the surrounding area of the separation point. Even the smallest particles of dirt, introduced into the hydraulic components, can result in malfunctions and a total failure of the SBC system
- When carrying out service and repair operations on the front-end assembly, always take great care to prevent leaving scratches, notches or fissures in the aluminum components. Otherwise the service life of the parts will be affected
- See notes on self-locking nuts and bolts
- See Special information on AIRmatic.

NOTE: Installation: Tighten nuts and bolts of chassis components only in curb condition.
