3.9 BATTERY MAINTENANCE
All lead-acid batteries will discharge when not in
use. The generator battery should be inspected as
follows:
3.9.1 WEEKLY
Inspect the battery posts and cables for tightness •
and corrosion. Tighten and clean as necessary.
Check the battery fluid level of unsealed batteries •
and, if necessary, fill with Distilled Water Only. Do
not use tap water in batteries.
3.9.2 EVERY SIX MONTHS
Have the state of charge and condition checked. •
This should be done with an automotive-type bat-
tery hydrometer.
NOTE:
Servicing of the battery is to be performed or
supervised by personnel knowledgeable of batter-
ies and the required precautions. Keep unauthor-
ized personnel away from batteries.
Damage will result if the battery connections are
made in reverse.
DANGER
Do not dispose of the battery in a fire. The
battery is capable of exploding. Storage batter-
ies give off explosive hydrogen gas. This gas can
form an explosive mixture around the battery
for several hours after charging. The slightest
spark can ignite the gas and cause an explo-
sion. Such an explosion can shatter the battery
and cause blindness or other injury. Any area
that houses a storage battery must be properly
ventilated. Do not allow smoking, open flame,
sparks, or any spark producing tools or equip-
ment near the battery. Discharge static electric-
ity from body before touching the battery by
first touching a grounded metal surface.
A battery presents a risk of electrical shock
and high short circuit current. The following pre-
cautions are to be observed when working on
batteries:
• Remove watches, rings or other metal objects;
• Use tools with insulated handles;
• Wear rubber gloves and boots;
• Do not lay tools or metal parts on top of the
battery;
• Disconnect any charging source prior to connecting
or disconnecting battery terminals; and
• Do not use any jumper cables or booster battery to
crank and start the generator engine. If any battery
has discharged, remove it for recharging.
Do not open or mutilate the battery. Released
electrolyte has been known to be harmful to the
skin and eyes, and to be toxic.
The electrolyte is a dilute sulfuric acid that is
harmful to the skin and eyes. It is electrically
conductive and corrosive. The following
procedures are to be observed:
• Wear full eye protection and protective clothing;
• Where electrolyte contacts the skin, wash it off
immediately with water;
• Where electrolyte contacts the eyes, flush
thoroughly and immediately with water and seek
medical attention; and
• Spilled electrolyte is to be washed down with an
acid neutralizing agent. A common practice is to
use a solution of 1 pound (500 grams) bicarbonate
of soda to 1 gallon (4 liters) or water. The bicar-
bonate of soda solution is to be added until the
evidence of reaction (foaming) has ceased. The
resulting liquid is to be flushed with water and the
area dried.
3.10 MAJOR SERVICE MANUAL
To obtain a service manual for the generator, contact
the nearest Authorized Service Dealer. Make sure to
identify the MODEL NUMBER and SERIES.
3.11 EXERCISING THE GENERATOR
The manufacturer recommends that the generator be
started and operated at least once every seven days.
Let the unit run for at least 30 minutes to “exercise”
the engine.
3.12 OUT OF SERVICE PROCEDURE
3.12.1 REMOVAL FROM SERVICE
If the generator cannot be exercised every seven days,
and it is to be out of service longer than 30 days, pre-
pare the generator for storage as follows:
1. Start the engine and let it warm up.
2. Close the fuel shutoff valve in the fuel supply line
and allow the unit to shut down.
Note:
Using a fuel additive such as STA-BIL fuel stabi-
lizer, or an equivalent, will prevent gum deposits
from forming in the engine’s fuel system.
3. While the engine is still warm from running, drain
the oil completely. Refill the crankcase with SAE
10W-30 oil having API classification “For Service
SF.”
