57.11 MAINTENANCE SCHEDULE
The maintenance schedule (see next page)
specifies the periodic maintenance procedures
and service intervals. Regular maintenance is
the best insurance against early wear and
untimely breakdowns. Following this schedule
will increase machine life. For detailed
instructions, refer to Sections 7.6 to 7.12. Use
the fluids and lubricants specified in Section
7.3.1, Recommended Fuel, Fluids and
Lubricants.
Service Intervals: The recommended service
intervals are in hours of operation. Where a
service interval is given in more than one time
frame, e.g. "100 hours or Annually", service the
machine at whichever interval is reached first.
IMPORTANT
Recommended intervals are for average
conditions. Service the machine more
often if operated under adverse conditions
(severe dust, extra heavy loads, etc.).
CAUTION
Carefully follow safety messages given
under Section 7.1 PREPARATION FOR
SERVICING, and Section 7.2
