6.4 BATTERY MAINTENANCE AND CHARGING
Battery Maintenance, Quarterly
1. Open battery compartment cover to allow access to bat-
tery terminals and vent caps.
WHEN ADDING WATER TO BATTERIES, ADD WATER UNTIL ELECTRO-
LYTE COVERS PLATES. DO NOT CHARGE BATTERIES UNLESS ELECTRO-
LYTE 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 batter-
ies after charging.
When adding water to the battery, fill only to level indi-
cated.
2. Remove all vent caps and inspect electrolyte level of
each cell. Electrolyte level should be to the ring approxi-
mately one inch from top of battery. Fill batteries 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 neutralizing
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 mineral 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 prop-
erly.
