DANGER
Do not carry passengers while the bus is being towed.
3.2 FIRST LIFT
A first lift of the bus is necessary. This first lift will allow tow cans or blocks to be placed underneath the
drive axle tires.
1. Prepare the bus 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 (fig.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
(fig.55).
No axle forks will be used for this first lift
TALL REGULAR
FIG.55
5. Deploy the tow truck stinger arm. Place the fork
holders under the engine cradle transverse
beam as shown on fig.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.
CAUTION
Use caution when lifting from the engine cradle
transverse beam. Maintain the bus in that
situation during the shortest period of time.
