ENGINE COOLANT
Check coolant level in coolant recovery bottle. See the
"Specifications" section.
• Add recommended coolant mixture as necessary.
• Periodically remove radiator pressure cap 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 an Authorized
Service Dealer. Inspect cooling system and coolant recovery
system 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 control box.
• The 120VAC supply to the battery charger is switched OFF.
• The negative battery cable has been removed.
CHECK ENGINE OIL LEVEL
Refer to the "Checking Fluid Levels" section.
CHECK BATTERY
• Check battery fluid level each week as outlined under "Check
Fluid Levels".
• Check battery cables for condition, tightness, corrosion or dam-
age. Clean, tighten or replace as necessary.
EXERCISE SYSTEM
Start the Stationary Emergency Generator engine at least once
every seven days and let it run at least 20 minutes. For more
detailed exercise information, see the respective sections in the
Control Panel Technical Manual that is supplied with the unit.
INSPECT COOLING SYSTEM
• Inspect engine cooling system at least once each month.
• 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-genera-
tor monthly. Look for obvious damage, loose, missing or corroded
nuts, bolts and other fasteners. Look for fuel, oil or coolant leaks.
Stationary Emergency Generator
Maintenance
Inspect the exhaust system at least once every three months.
Check all exhaust system pipes, mufflers, clamps, etc. for condi-
tion, tightness, leaks, security, damage.
• Inspect fan belts every three months. Replace any damaged,
deteriorated, worn or otherwise defective 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.
• Check fan belt alignment.
Visually inspect electronic governor.
Refer to maintenance performed by authorized service facilities for
engine oil and filter change frequencies.
Drain the oil while the engine is still warm from running. This
means warm up the engine, shut it down and drain immediately
as follows:
1.

INSPECT EXHAUST SYSTEM
CHECK FAN BELT
INSPECT ENGINE 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 personal
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 supplied only
at the proper governed speed. Some connected
electrical load devices may be damaged by
incorrect frequency and/or voltage. Only quali-
fied service technicians should adjust the gov-
erned speed.
CHANGING ENGINE OIL
Hot oil may cause burns. Allow engine to cool
before draining oil. Avoid prolonged or repeated
skin exposure with used oil. Thoroughly wash
exposed areas with soap.
Remove OIL DRAIN HOSE from its retaining clip.
Loosen and remove OIL DRAIN HOSE CAP . Drain oil com-
pletely into suitable container.
When all oil has drained, install and tighten OIL DRAIN HOSE
CAP , and re-install into its retaining clip.
Turn OIL FILTER (Figure 10.2) counterclockwise and remove.
Dispose of old filter.
Apply light coating of new engine oil to seal of new oil
filter.-Install FILTER and tighten by hand only. DO NOT
OVERTIGHTEN.
