3.9 BATTERY MAINTENANCE AND
CHARGING
Battery Maintenance, Quarterly
1. Open battery compartment cover to allow access to
battery terminals and vent caps.
WHEN ADDING WATER TO BATTERIES, ADD WATER UNTIL ELEC-
TROLYTE COVERS PLATES. DO NOT CHARGE BATTERIES UNLESS
ELECTROLYTE COVERS THE PLATES.
NOTE: When adding distilled water to batteries, non-metallic
containers and/or funnels must be used.
To avoid electrolyte overflow, add distilled water to
batteries after charging.
When adding water to the battery, fill only to level
indicated or 3/8”(1 cm) above separators.
2. Remove all vent caps and inspect electrolyte level of
each cell. Electrolyte level should be to the ring
approximately one inch from top of battery. Fill bat-
teries with distilled water only. Replace and secure
all vent caps.
3. Remove battery cables from each battery post one
at a time, negative first. Clean cables with acid neu-
tralizing solution (e.g. baking soda and water or
ammonia) and wire brush. Replace cables and/or
cable clamp bolts as required.
4. Clean battery post with wire brush then re-connect
cable to post. Coat non-contact surfaces with min-
eral grease or petroleum jelly.
5. When all cables and terminal posts have been
cleaned, ensure all cables are properly positioned
and do not get pinched. Close battery compartment
cover.
6. Start hydraulic system and ensure that it functions
properly.
