unit maintenance
GENERAL MAINTENANCE
NOTE: Some maintenance services, such as engine repairs, electrical repairs, etc., should be
performed only by a qualified technician.
•
Check overall condition of unit prior to each use, repairing or replacing worn, damaged or
missing components promptly. Check all fasteners regularly and tighten if necessary.
•
Follow engine manufacturer’s recommendations for maintenance schedules. Use only
recommended parts, fluids and lubricants. Failure to follow manufacturer’s recommendations
may void manufacturer’s warranties.
•
Lubricate impeller shaft bearings every 50 hours of operation. Use a high quality bearing
grease, available from your local dealer (or auto parts store).
•
Maintain tire pressure as indicated on tire sidewall. Replace worn or damaged tires promptly.
•
Keep engine free from a buildup of grass, leaves or excessive grease. An accumulation of
these combustible materials may result in a fire, or simply impede performance.
•
Never change attachments or make any adjustments, repairs or replacements until the unit is
completely shut down and the battery is disconnected.
CHECKING AND ADJUSTING IMPELLER BELTS
NOTE: Check new belts frequently during first 24-48 hours of installation, as tension will
decrease significantly due to belt seating.
To obtain optimum performance and longer life from your belts, check and adjust tension using a belt
tension checker, available at any auto parts dealer.
•
Remove drive belt top cover.
•
Take an initial tension check. Good belt tension is generally between 8-10 lbs. With a 3/8”
deflection.
•
If adjustment is needed, loosen the four engine mounting bolts.
Do not completely remove
bolts.
•
Loosen the two threaded tensioning rods opposite the impeller side of the engine,
making
sure to loosen both the same number of turns in order to avoid misaligning the engine.
