VENT PLUGS
Always keep the vent plugs in place and tight. Be sure the vent holes are free of dirt
to prevent gas pressure in cells from breaking the seal of the container.
CABLE TERMINALS AND BATTERY POSTS
The battery terminals must be kept clean and tight . A good method of cleaning
terminals is to remove all excess corrosion with a wire . brush, then wash with a weak
baking soda solution or ammonia. After cleaning, a thin coating of vaseline or light cup
grease
will retard further corrosion.
CAUTION : When removing a battery. always disconnect the (-)
A
negative ground cable first _ When installing the battery. always
connect the (-) negative ground cable last.
IDLE BATTERY
When the Tractor is not in active use, the battery will requ ir e a charge at suff i cient
intervals to keep the hydrometer reading at or above 1.250 . An idle storage battery will
slowly discharge.
