FIRST LIFT

A first lift of the vehicle is required. This first lift will allow tow cans or blocks to be placed underneath the
drive axle tires.
1. Prepare the vehicle for towing as instructed in
paragraphs 2.1 and 2.1.1
2. If not already done, chock the front wheels.
3. Retract the tow truck stinger arm (Figure 55).
4. Pre-adjust spacing between the axle fork
holders. The spacing between the most distant
edges of the folk holders should be 30 inches
(Figure 55).
No axle forks will be used for this first lift
TALL
5. Deploy the tow truck stinger arm. Place the fork
holders under the engine cradle transverse
beam as shown on Figure 56. Lift the tow bar
until the fork holders come into contact with the
cradle transverse beam.
Lifting from the engine cradle is the least
preferred option and should be done only if
lifting from under the side members shown
on Figure 53 cannot be achieved
CAUTION
Remember, lifting the rear end from the side
members located under the engine cradle or
by the engine cradle itself may cause
structural damage.
6. Raise the tag axle to prevent it from hanging
unsupported.
