If your Medium Duty vehicle is serviced regularly, you can
avoid many large, expensive, and time-consuming repairs, as
well as ensuring many years of safe and smooth operation.
Also, be advised that neglect of recommended service may
in some cases void your vehicle's warranty. So, for your

nance Schedule,” Page 157
. But remember, there may be
maintenance operations that demands skills and equipment
you do not have. If so, please take your Medium Duty vehicle

formance.
WARNING! It can be dangerous to attempt main-
tenance work without sufficient training, service
manuals, and the proper tools. You could be
killed, injured or you could make your vehicle
unsafe. Do only those tasks you are fully trained
and equipped to do.
In severe operating conditions such as mining, logging, or
earth moving, you will need to perform maintenance checks
and services more frequently. Other “severe operating condi-
tions” to be aware of are: rough, extreme temperature envi-
ronments; conditions where heavy loads are being hauled;
contaminated environments, or steep grades. Consult the
component manufacturer's maintenance manuals for further
information on maintenance procedures specific to these
conditions.
