WARNING
The jacking points on the tag axle must be
used for raising the tag axle only.
Several kinds of hydraulic jacks can be used.
Only jack at the specified jacking points. Jack
must support the following weight:
Front axle: 20,000 lbs. (9 100 kg);
Drive axle: 40,000 lbs. (18 200 kg).
WARNING
Do not jack vehicle with passengers inside.
Coach weight depends on equipment and
cargo within. Check before jacking.
HYDRAULIC JACK
To raise: turn release valve clockwise. Insert
handle in socket and raise by pumping.
To lower: remove handle and turn the release
valve slowly counterclockwise.
Always keep ram and extension screw retracted
when jack is not in use.
Service: Check oil level when jack fails to raise to
full height. Lower ram completely with release
valve open and jack in upright position, remove
filler plug and refill to level of filler hole with
hydraulic jack oil. Never use brake fluid.
WARNING
Jack is intended for lifting only. Do not get
under the vehicle or load for any reason
unless it is properly supported with safety
stands and securely blocked.
WARNING
Do not load jack above rated capacity. Prevent
"side loading"; make sure load is centered on
ram. Do not push or tilt load off jack.
TOWING THE VEHICLE
The vehicle can be transported on a low bed
semi-trailer of adequate gross axle weight
capacity. When transporting a vehicle in this
manner, apply parking brake and shut down the
engine. Block all wheels and secure vehicle with
tie-downs. Check that overall height will clear
obstacles on the route to follow, and obtain
required permits.
The vehicle can also be towed by lifting the front
axle or by towing from the front with all wheels
on the ground. These two methods are
described below under their respective
headings. Whatever the method used, the
vehicle should be towed by truck operators
authorized and experienced in towing highway
coaches.
Observe normal precautions including, but not
limited to, the ones listed below when towing
the vehicle:

Make sure the parking brake is released
before towing.

Do not allow passengers to ride onboard the
towed vehicle.

Tow the vehicle at a safe speed as dictated by
road and weather conditions.

Accelerate and decelerate slowly and
cautiously.
WARNING
Do not carry passengers while the coach is
being towed.
CAUTION
Never tow the vehicle from the rear, as this
will cause serious damage to the chassis and
engine cradle. In case of damage to the drive
train components, use a low bed semi-trailer
to support the rear end.
LIFTING AND TOWING
The towed vehicle must be lifted from the front
end only. The tow truck must be equipped with
