Engine Care
A list of key engine maintenance jobs required for good
performance by the mower is given below. Follow the
accompanying engine manual for a detailed list and instructions.
• Maintain oil level as instructed in engine manual.
• Service air cleaner every 25 hours under normal conditions.
Clean every few hours under extremely dusty conditions.
Poor engine performance and flooding usually indicates
that the air cleaner should be serviced. To service the air
cleaner, refer to the engine manual.

plug replacement is recommended at the start of each
mowing season. Check engine manual for correct plug
type and gap specifications.
