7.4 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 ELECTROLYTE COVERS
PLATES. DO NOT CHARGE BATTERIES UNLESS ELECTROLYTE COVERS THE PLATES.
NOTE: When adding distilled water to batteries, non-metallic contain-
ers 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.
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 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 properly.
