BTAD is now ready for operation.
To Relocate:
Position Dolly Jack Tow Bar under the rear lift plate, raise. The Flipup/Flip down Wheels will automatically lower and lock in mobile
position. Then, place tow bar under front lift plate and move to next
location. Important: Do not load BTAD when in the mobile position
or attempt to move while loaded
