First Lift - PREVOST H3-41 Maintenance Manual

CAUTION
The axle shafts must be disconnected to avoid serious damage to the Allison transmission. Lubrication
is inadequate when towing.
To prevent damage to the drive train components, disconnect drive axle shafts before towing. Do not
attempt to push or pull start a vehicle equipped with an automatic transmission.
Failure to disconnect the propeller shaft, remove the drive axle shafts or lift the drive wheels off
the ground before towing can cause serious transmission damage and void the warranty.
2.2.1

First Lift

To allow lifting equipment fitted with axle forks to reach under the front axle or tow eyes, it is necessary
to perform a first lift of the front of the vehicle using the tow eye pads as lifting points. This first lift will
allow tow cans or blocks to be placed underneath front tires.
1. Retract the tow truck stinger arm.
2. On the first lift, position the tow bar fork
holders under the front tow eye pads
(Figure 30 and Figure 31) to lift the
vehicle in order to place the front
wheels firmly on the tow cans or blocks.
Center to center measurement between tow
eyes= 37 inches (Figure 29)
Note: No axle forks are needed for this
first lift
