Maintenance
The maintenance section is a guide to equipment care.
The Maintenance Interval Schedule lists the items to be
maintained at a specific service interval. The Maintenance
Interval Schedule lists the page number for the step-by-
step instructions required to accomplish the scheduled
maintenance procedure.
Maintenance Intervals
Use the service hour meter to determine servicing intervals.
Calendar intervals shown (daily, weekly, monthly, etc.) can be
used instead of service hour meter intervals if they provide
more convenient servicing schedules and approximate the
indicated service hour meter reading. Recommended service
should always be performed at the interval that occurs first.
Under extremely severe, dusty or wet operating conditions,
more frequent lubrication than is specified in the maintenance
intervals chart might be necessary.
Perform service on items at multiples of the original
requirement. For example, at every 100 service hours, also
service those items listed under every 50 service hours and
every 10 service hours or daily.
