WHEEL LIFT OPERATION

The optional wheel lift allows a second vehicle to be towed damage free on

its own suspension by utilizing a wheel grid. The wheel lift cross bar may

also be used as a conventional tow bar for badly damaged or heavier vehicles.

Refer to the AAA or vehicle manufacturer's towing manual for the

correct towing procedures and attachment points.

WARNING:

Because of the additional boom extension and load point of the

towed vehicle, the wheel lift places more load on the rear axle and

unloads the front axle more than a conventional tow bar.

Overloading the wheel lift may result in unsafe steering and braking

conditions and may damage truck frame. Never use the wheel lift

without a vehicle on the deck. Single vehicle recovery must utilize

the deck only.
