CARE AND MAINTENANCE
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 overload jack above rated
capacity. Prevent "side loading", make sure load
is centered on ram. Do not push or tilt load off
jack.
Towing
To prevent damage to the motorcoach, use the
two tow eyes located under the back bumper
and/or fixed to the motorcoach's frame between
the front axle and the front bumper. Use only a
solid link tow bar and a safety chain to tow the
motorcoach. If required, connect an auxiliary air
supply to the vehicle so brakes can be operated
while towing.
Warning :
During a towing operation, the
driver should be alone inside the motorcoach.
Caution :
To prevent damage to the
drivetrain components, disconnect axle shafts or
driveshaft before towing. Do not attempt to push
or pull-start a motorcoach equipped with an
automatic transmission.
Note :
Make sure axle shafts or driveshaft
are installed correctly after towing. Tighten axle
shaft and driveshaft nuts to the correct torque
settings. Do not invert shafts.
Doors
Close all exterior doors and windows. Check for
good tightness and fit.
Tools And Spares
Make sure the motorcoach is equipped with a
wheel nut wrench, door keys, spare belts,
reflectors and jack.
Air System
To purge water from air and accessory tanks,
open drain cocks. Close drains when
completed. Refer to heading "Air Tank Purge" in
this chapter.
Water Separator
To purge water separator, loosen bleed screw.
Tighten bleed screw after purging.
Coolant Level
Check coolant level. Coolant level is correct
when visible in the filler neck of the surge tank.
If coolant level is low, fill system with 50-50
coolant mixture. Refer to the motorcoach
"Maintenance Manual" for more information.
Warning :
Hot engine coolant is under
pressure. Do not attempt to open the coolant
filler cap when the engine is hot. Allow engine to
cool before adding coolant.
Wheel Bearings
Check wheel bearing oil level in sight glass.
Refer to heading "Wheel Bearing Oil Level" in
this chapter.
Caution :
Check wheel bearing cover for
overheating (especially after brake work) during
fuel stops by touching the wheel bearing cover.
Windshield Washer Reservoir
Make sure windshield washer reservoir is full.
For cold weather, use antifreeze windshield
washer to prevent freezing.
