Note that many of the tests and checks listed in the
schedule are to be performed only by an Authorized
Service Technician. Fluid capacities and recommen-
dations, as well as other applicable specifications,
are listed in the "Specifications" section.
4.2.1 TEST STANDBY GENERATOR SYSTEM
OPERATION AND COMPONENTS
An authorized operator should test the operation
of the standby generator system and inspect its
components monthly (or 100 hours). This should
include inspecting the transfer switch for evidence
of arcing, and pitted or burned contacts. Inspect
wiring and grounding connections (see "Grounding
the Generator") and ensure that starting devices are
operational. During this operational test, all instru-
ment and gauge readings should be recorded in a
"Maintenance Log." The transfer system also should
be tested at this time. The engine should also be ran
at least 30 minutes and any discrepancies corrected
immediately.
Every six months (or 200 hours), an Authorized
Service Technician should perform a system opera-
tional test.
4.2.2 INSPECT BATTERY
Standby generators installed with automatic
transfer switches will crank and start automati-
cally when NORMAL (UTILITY) source voltage is
removed or is below an acceptable preset level.
To prevent such automatic start-up and pos-
sible injury to personnel, do not connect battery
cables until certain that NORMAL source voltage
at the transfer switch is correct and the system
is ready for operation.
Storage batteries give off explosive hydrogen
gas. This gas can form an explosive mixture
around the battery for several hours after charg-
ing. The slightest spark can ignite the gas and
cause an explosion. Such an explosion can shat-
ter the battery and cause blindness or other
injury. Any area that houses a storage battery
must be properly ventilated. Do not allow smok-
ing, open flame, sparks or any spark producing
tools or equipment near the battery.
Battery electrolyte fluid is an extremely caus-
tic sulfuric acid solution that can cause severe
burns. Do not permit fluid to contact eyes, skin,
clothing, painted surfaces, etc. Wear protective
goggles, protective clothing and gloves when
handling a battery. If fluid is spilled, flush the
affected area immediately with clear water.
DANGER
Section 4 – Maintenance
Standby Generator Set
Do not dispose of the battery in a fire. The
battery is capable of exploding.
Do not open or mutilate the battery. Released
electrolyte can be toxic and harmful to the skin
and eyes.
The battery represents a risk of high short circuit
current. When working on the battery, always
remove watches, rings or other metal objects,
and only use tools that have insulated handles.
An authorized operator should inspect the engine
battery system monthly (or 100 hours). At this time,
the battery fluid level should be checked and distilled
water added if needed. Battery cables and connec-
tions also should be inspected for cleanliness and
corrosion.
Once every six months (or 200 hours), an Authorized
Service Technician should inspect the battery system.
At this time the battery condition and state of charge
should be checked using a battery hydrometer. The
battery should be recharge or replaced as required.
4.2.3 BATTERY REPLACEMENT
When replacing batteries, use the same number and
the following type batteries.
Part Number
BCI Group No.
058665
The BCI number should be located directly
on the battery. For more information, see
"Specifications."
4.2.4 CHECK FLUIDS
An authorized operator should check the levels
of engine oil, and engine coolant monthly (or 100
hours). The oil level should be maintained between
the "FULL " and "ADD" marks on the engine dipstick.
Recommended fluids are listed in the "Specifications:
section.
4.2.5 INSPECT EXHAUST SYSTEM
Every three months (or 120 hours), an authorized
operator should inspect the entire exhaust system.
Abnormal noise levels heard during each operational
test may indicate a defective exhaust pipe or muf-
fler. Any defective or leaking component should be
repaired or replaced immediately by an Authorized
Service Technician.
