EXPLANATION OF SCHEDULED MAINTENANCE
Check at recovery tank, if empty, check at manifold. Add coolant if needed.
Oil level should indicate between MAX and LOW on dipstick. Do not overfill!
CAUTION: The oil sump on this generators engine can unintentionally be over-mledl
}\fter sht.it-down, the oil in the engines internal passag~s can linger and take a number of
hours to drain back into the oil sump. Allow at least a few hours for the oil to settle back
into the sump before checking the dipstick. An overnight period will provide an even more
accurate dipstick reading. (Re-starting the engine is not a problem as the engine's internal
passages are well lubricated).Over-filling the engines sump will result in erratic operation,
and/or smokey white oil laden exhaust, hard starting and possibly no start.
Check for water and dirt in fuel. Drain filter if necessary. Repla~e filter every 250 operating
hours or once a year,
Fresh unleaded gasoline with an octane rating of 89 or higher.
Check for fuel, oil and water and exhaust leaks. Check for rust or corrosion. Inspect wiring
and electrical connections. Ensure that bolts and nuts are tight. Surface of engine should be
kept clean.
Initial adjustment (engine cold).
Measure spring length. Inspect belt condition. Adjust spring length as needed.
Initial engine oil and filter change at 50 hours, then change both every 100 hours.
Initial check at 50 hours, then every 250 hours or once a year. Carefully inspect for leaks.
Check anti-siphon valve operation. Check that the exhaust elbow for carbon and/or corrosion
buildup on inside passages: clean and replace as necessary.
Inspect/clean.
Initial change.
Initial change.
Check gap (0.035in (0.8 - 0.9mm).
Initial cleaning of screen.
Adjust belt tension (3/8 -1/2 deflection).
Check electrolyte levels Make sure cables and connections are in good order. Clean
off corrosion if needed. Apply petroleum jelly to terminals for corrosion protection.
Inspect for leaks, ensure fuel and electrical connections are clean and tight.
NOTE: Work out your own schedule, boats location, use of s/'tore power can make a
difference. Inspect monthly to determine schedule.
Change engine oil and filter.
Remove, clean and re-install screen pack.
Check for wear, cracks and stretching.
Inspect plug gap. AdjusVreplace as .needed.
Inspect impeller(s) for condition. Rep~ce as needed.
NOTE: Refer to Service Bulletin #276 dated 6 May 2015 when performing generator drive belt
adjustment.
