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.
