MAINTENANCE/SERVICE
MAINTENANCE SCHEDULE
The following maintenance schedule is a listing of periodic maintenance procedures, organized by service
intervals. For detailed instructions, see the specific headings in Maintenance/Service section. Use
“Recommended Lubricants” as specified under that heading.
Service Intervals
The recommended service intervals are in hours of operation. Use the hour meter in the combine to indicate
when the next service interval has been reached.
IMPORTANT: Recommended intervals are for average conditions. Service the adapter more often if operated
under adverse conditions (severe dust, extra heavy loads, etc.).
Regular maintenance is the best insurance against early wear and untimely breakdowns. Following this
schedule will increase machine life.
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.
CAUTION: Carefully follow safety messages given under “Service Procedures”.
