Correct any discrepancies found.
• Check hose clamps for tightness.
4.5.5 CHECK ENGINE COOLANT LEVEL
See "Checking Fluid Levels" in Section 4.4.
4.5.6 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.
4.5.7 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.
4.5.8 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 inch. Adjust belt tension as required.
4.5.9 INSPECT ENGINE GOVERNOR
Visually inspect electronic governor.
DANGER
Do not attempt to adjust the governor. Only
!
qualified service facilities should adjust the
governor. Excessively high operating speeds
are dangerous and increase the risk of person-
al injury. Low speeds impose a heavy load on
the engine when adequate engine power is
not available and may shorten engine life.
Correct rated frequency and voltage are sup-
plied only at the proper governed speed.
Some connected electrical load devices may
be damaged by incorrect frequency and/or
voltage. Only qualified service technicians
should adjust the governed speed.
