CAUTION:

• If
itbecomes necessary tostart theengine withabooster
battery andjumper cables, usea12-volt booster battery.
• After connecting batterycables, ensurethatthey aretightly
clamped tobattery terminals forgood contact.
• Never adddistilled waterthrough thehole used tocheck
specific gravity.
How toHandle Battery
METHODS OFPREVENTING OVER-DISCHARGE

T.he following precautions mustbetaken toprevent over-dis-
charging abattery.
• The battery surface (particularly itstop) should always be
kept clean anddry.
• The terminal connections shouldbeclean andtight.
• Atevery routine maintenance, checktheelectrolyte level.

SEL459R
•
When thevehicle isnot going tobe used overalong period
of time, disconnect thenegative batteryterminal. (Ifthe
vehicle hasanextended storageswitch,turnitoff.)
• Check thecharge condition ofthe battery.
Periodically checkthespecific gravityofthe electrolyte.
Keep aclose check oncharge condition toprevent overdis-
charge.

CHECKING ELECTROLVTELEVEL •
WARNING: Do not allow battery fluidtocome incontact withskin, eyes,
fabrics, orpainted surfaces. Aftertouching abattery, donot
touch orrub your eyes untilyouhave thoroughly washedyour
hands. Ifthe acid contacts theeyes, skinorclothing, immedi-
ately flush withwater for15minutes andseek medical atten-
tion.

• Check battery typeanddetermine thespecified currentusingthetable
shown above.
• After starting charging, adjustment ofcharging currentisnot necessary.

CAUTION: • Donot use quick charge method onabattery whosespecific gravityisless than 1.100.
• Set initial charging currenttovalue specified inFig. 6.Ifcharger isnot capable ofproducing spec-
ified current value,setitscharging currentasclose tothat value aspossible.
• Keep battery awayfromopen flame whileitis being charged.
• When connecting charger,connectleadsfirst,thenturnoncharger. Donot turn oncharger first,as
this may cause aspark.
• Becareful ofarise inbattery temperature becausealarge current flowisrequired duringquick-
charge operation.

If
battery temperature risesabove 60°C(140°F), stopcharging. Alwayschargebatterywhenitstem-
perature isbelow 60°C(140°F).
• Donot exceed thecharging timespecified inFig. 6,because charging batteryoverthecharging time
can cause deterioration ofthe battery.
