• Remove oil dipstick and wipe dry with a clean, lint-
free cloth.
• Install oil dipstick, then remove again.
• Oil should be between FULL and ADD marks.
• If oil level is below the dipstick ADD mark, remove
oil fill cap-. Add the recommended oil to bring oil
level up to the FULL mark. DO NOT FILL ABOVE
THE “FULL” MARK. See “Engine Oil Recommen-
dations” for recommended oils.
BATTERY FLUID
‹
Check battery electrolyte fluid based on the
Maintenance Schedule. Fluid should cover separa-
tors in all battery cells. If fluid level is low, add dis-
tilled water to cover tops of separators. DO NOT USE
TAP WATER IN BATTERY.
ENGINE COOLANT
‹
Check coolant level in coolant recovery bottle. See
the Specifications section.
• Add recommended coolant mixture as necessary.
• Periodically remove radiator pressure cap (only
when engine has cooled down) to make sure the
coolant recovery system is functioning properly.
Coolant should be at bottom of radiator filler neck.
If coolant level is low, inspect gasket in radiator
pressure cap. Replace cap, if necessary. To have
pressure cap tested, contact a Service Facility.
Inspect cooling system and coolant recovery sys-
tem for leaks.
MAINTENANCE OWNER/
OPERATOR CAN PERFORM

Before working on the generator, ensure the fol-
lowing:
• The AUTO/OFF/MANUAL switch is in the OFF
position.
• The 15A fuse has been removed from the con-
trol box.
• The 120VAC supply to the battery charger is
switched OFF.
• The negative battery cable has been removed.
CHECK ENGINE OIL LEVEL

Refer to “Checking Fluid Levels”.
CHECK BATTERY
‹
• See “Checking Fluid Levels”.
• Check battery cables for condition, tightness, cor-
rosion or damage. Clean, tighten or replace as
necessary.
EXERCISE SYSTEM
‹
Start the generator engine at least once every seven
days and let it run at least 20 minutes. For more
detailed exercise information, see the respective sec-
tions in the Control Panel Technical Manual that is
supplied with the unit.
INSPECT COOLING SYSTEM
‹
• Inspect engine cooling system. See “Maintenance
Schedule”.
• Check hoses for damage, deterioration, leaks, etc.
Correct any discrepancies found.
• Check hose clamps for tightness.
CHECK ENGINE COOLANT LEVEL
‹
See the “Checking Fluid Levels” section.
PERFORM VISUAL INSPECTION
‹
Complete a thorough visual inspection of the entire
engine-generator monthly. Look for obvious damage,
loose, missing or corroded nuts, bolts and other fas-
teners. Look for fuel, oil or coolant leaks.
INSPECT EXHAUST SYSTEM
‹
Inspect the exhaust system at least once every three
months. Check all exhaust system pipes, mufflers,
clamps, etc. for condition, tightness, leaks, security,
damage.
CHECK FAN BELT
‹
• Inspect fan belts every three months. Replace any
damaged, deteriorated, worn or otherwise defec-
tive belt.
• Check fan belt tension. Thumb pressure, exerted
midway between pulleys, should deflect about 3/8
to 5/8 of an inch. Adjust belt tension as required.
• Check fan belt alignment (see Figure 10.2).
