MAINTENANCE
PERIODIC MAINTENANCE CHART:
To ensure satisfactory operation over an extended
period of time, an engine requires normal maintenance
at regular intervals. The Periodic Maintenance Chart
below shows periodic inspection and maintenance items
and suitable intervals. The bullet mark designates that
the corresponding item should be performed at that
interval.
NOTE: Some adjustments require the use of special tools
or other equipment. An electronic tachometer will
facilitate setting idle and running speeds.
