General engine maintenance
Detailed instructions and recommendations for break-in and regular maintenance are specified in the
Engine Owner’s manual. Please refer to this manual for engine servicing, lubricating oil levels with quality
and viscosity recommendations, bolt torques, etc. The engine warranty is backed by the manufacturer.

Belt replacement
"FIG. 41", "FIG. 42", "FIG. 43" & "FIG. 44" show diagrams and descriptions of the unit’s belt drive systems.
Inspect these belts frequently for wear and serviceability. Replace a belt that shows signs of severe cuts,
tears, separation, weather checking and cracking, or burns caused by slipping. Slight raveling of belt
covering does not indicate failure, trim ravelings with a sharp knife.
