BATTERY FLUID
Check battery electrolyte fluid based on the Maintenance Schedule.
Fluid should cover separators in all battery cells. If fluid level is low,
add distilled 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 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 Dealer. Inspect
cooling system and coolant recovery system for leaks.
MAINTENANCE OWNER/
OPERATOR CAN PERFORM
 Before working on the generator, ensure the
following:
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.
INSPECT EXHAUST SYSTEM
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.
CHECK FAN BELT
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.
INSPECT ENGINE GOVERNOR
Visually inspect electronic governor.
DANGER
n
Do not attempt to adjust the governor. Only
qualified service dealers should adjust the
governor. Excessively high operating speeds
are dangerous and increase the risk of per-
sonal 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 gov-
erned speed. Some connected electrical
load devices may be damaged by incorrect
frequency and/or voltage. Only qualified ser-
vice technicians should adjust the governed
speed.
