10.2 MAINTENANCE CHART
The MAINTENANCE CHART indicates the various components and the intervals when maintenance has to take
place. Where a service interval is stated in both hours and months, it is the sooner of the two intervals that must
be adhered to. Coolant capacities etc can be found in the GENERAL INFORMATION section of this manual. Note
that any Local or National codes that require specific maintenance that exceeds the requirements of this section
must be adhered to.
