ENGINE MAINTENANCE
• Check oil level before each use and every 8 hours.
• Maintain engine oil as instructed in the separate
engine manual.
• Service air cleaner every 25 hours under normal
conditions. Clean every few hours under extremely
dusty conditions. Poor engine performance and
ooding usually indicates that the air cleaner should
be serviced. To service the air cleaner, refer to the
separate engine manual.
• Spark plug replacement is recommended every 100
hours or yearly. Check the engine manual for correct
plug type and gap specications.
