    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.

  162. Using suitable straps or chains, secure the vehicle to the hoist arms.
