Maintenance Instructions
10. Correct any problems that were revealed during inspection
prior to operating the vehicle.
Supporting Your Vehicle for Service
WARNING
Always use floor stands to support the vehicle
before working under it. Using only a jack could
allow the vehicle to fall resulting in property
damage, personal injury, or death.
When performing service repairs on a vehicle, first:
1. Park vehicle on level concrete floor.
2. Set parking brake and/or block wheels to prevent vehicle
from moving.
3. Select jack with a rated capacity sufficient to lift the
vehicle.
4. Raise vehicle with jack applied to axle. (Do not use
bumper as a lifting point.)
5. Support vehicle with floor stands under axle(s).
If axle or suspension components are to be serviced, support
vehicle with floor stands under frame side members, preferably
between the axles.
Chassis Lubrication
New vehicles are lubricated at the factory and again during the
predelivery inspection. After the vehicle is placed in operation,
regular lubrication and maintenance intervals, based on the type
of service and road conditions, should be established. The loads
carried, speed, road, and weather conditions all contribute to
the frequency of lubrication intervals. Thorough lubrication and
maintenance at the specified intervals will ensure Outstanding
Life Cycle Value and will reduce overall operating expense.
In some types of operation, and where operating conditions are
extremely severe (such as road salt or corrosive chemical
environments,
in deep water, mud, or unusually dusty
conditions), the vehicle may require relubrication after every 24
hours of operation.
Only lubricants of superior quality, such as Fleetrite® lubricants,
should be used. The use of inferior products will reduce the
service life of the vehicle or result in failure of its components.
The use of Fleetrite® lubricants and OEM original equipment
parts is recommended.
The lubrication intervals specified should be performed at
whatever interval occurs first, whether it is miles (kilometers),
hours, or months.
These intervals are provided in SECTION 7 — MAINTENANCE
