Removal Procedure

  1. Raise the vehicle.
  2. Caution: Provide additional support when a vehicle is on a hoist in the following ways:

       • Before removing major components, chain the vehicle frame to the hoist pads at the same end as the removal. This helps avoid a tip-off.
    Failure to follow these precautions could cause vehicle damage, serious personal injury, or death.
