3.5 Battery and Charging System
Mishandling of the battery shortens its service life and adds to maintenance cost.
1. Check and clean battery terminals for corrosion often.
2. Check the battery regularly and make sure that each electrolyte level is to the bottom of
the vent well. If necessary, add only distilled water in a well ventilated area. Never operate
or recharge without sufficient fluid in the battery.
3. Never attempt to charge a battery that is frozen. The battery can explode unless first al-
lowed to thaw.
4. ALWAYS be sure that the battery cables are properly connected to the battery terminals as
shown below. Generally the
RED
cable will be connected to the positive terminal of the battery,
and the BLACK cable will be connected to the negative terminal of the battery.
5. Disconnect the negative terminal ( - ) of the battery during storage. If unit will be stored
where ambient temperature will drop to -15° C or less, remove and store battery in a warm, dry
place.
