    Caution: Provide additional support when a vehicle is on a hoist in the following ways:

       • Before removing parts, support the opposite end. This helps prevent the vehicle from slipping off.
       • 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.

  1. Raise the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.

Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.
