Onan CCK Series User Manual

36 ABNORMAL OPERATING CONDITIONS
HIGH TEMPERATURES
LUBRICATION. - In temperatures above 90
0
(320C.) for continuous
operation use SAE number 50 oil. Keep the oil level
close to the full level, and change the oil at least every 100 operating
hours. .
COOLING. -
The engine and generator of this plant depend upon a con-
stant supply of fresh air for proper cooling. See that no-
thing obstructs the circulation of air to and around the plant. Keep
cooling fins clean and unobstructed. Make Sure that the blower housing
and cylinder air housings are properly in place and are undamaged.
Keep the ignition timing properly adjusted.
BATTERY PREPARATION FOR REMOTE START AC PLANT. - For a
usual
plant installation, follow the instructions for Batteries under INSTAL-
LATION
.. However, standard automotive/type batteries will seU-dis- .
charge rapidly when installed where the ambient temperature is con-
sistently above 90
0
F~, such as in a boiler room. Battery life is con-
siderably shorter under such high temperature conditions. To lengthen
battery life, reducethe electrolyte from a normal 1. 275 specific gravity
reading at full charge, to a 1. 225 reading. Attach a tag to the battery,
noting that the specific gravity has been reduced •.

the cranking power of the battery is somewhat reduced when its electro-
lYte is diluted for longer life, but if the temperature is consistently high
the reduced power will not be noticed.
1. Fully charge the battery. DO NOT BRING AN OPEN FLAME OR
BURNING CIGARETTE NEAR THE BATTERIES ON CHARGE BE-
CAUSE THE GAS RELEASED DURING CHARGING IS VERY FLAM-
MABLE.
2. While battery is on charge, use a hydrometer or filler bUlb to si-
phon off all of the electrolyte above the plates in each cell. Do not
I;lttempt
to pour off!! Dispose. of the removed electrolyte. AVOID
SKIN
OR CLOTHING CONTACT WITH ELECTROLYTE.
3. Fill each cell with pure distilled water.
4. Recharge the batteries for one hour at a 4 to 6 ampere rate.
5. Use a reliable battery hydrometer, to test each cell. If the speci-
fic gravity is above 1.225, repeat steps number 2, 3, and 4 until the
highest specific gravity r.eading ~f the fully charged battery is not
~ver 1.225. Most batteries reqUIre repeating steps 2 3 and 4·t
times. ' ,
