WARNING: The electrical power to the air suspension system must be shut off prior to hoisting, jacking or towing an air suspension vehicle. This can be accomplished by turning off the air suspension switch located in the rear jack storage area. Failure to do so can result in unexpected inflation or deflation of the air springs, which can result in shifting of the vehicle during these operations.

WARNING: Asbestos fiber dust can be present on brake and clutch assemblies and is hazardous to health if inhaled.

Brake and clutch assemblies should be cleaned using a vacuum cleaner recommended for use with asbestos fibers, such as a brake/clutch/service vacuum. The bag must be labeled per with OSHA instructions, sealed, and the trash hauler notified as to the bag's contents.

If a vacuum suitable for asbestos is not available, cleaning should be done wet. If dust generation is still possible, technicians must wear government-approved toxic dust purifying respirators.

Occupational Health and Safety Act (OSHA) requires areas where asbestos dust generation is possible to be isolated and posted with warning signs. Only technicians performing brake or clutch repair are to be present in the area.
