    GENERAL SAFETY MEASURES • Do not work under the vehicle when it is standing on jacks. • Always ensure that the vehicle is blocked and unable to move before operating the hydraulic levelling system. • If present, shut off the air suspension system, but do ensure that air remains in the bellows to prevent damage.
  • Page 5: Levelling Safety Measures

    LEVELLING SAFETY MEASURES • Park the vehicle on a surface that is as flat as possible. • Check if the surface on which the jacks will rest is preferably flat, not slippery, and free of debris, rocks, etc. • When parking on a soft surface, plates or blocks must be used under the bases of the jacks, to prevent the supports sinking into the ground.
