Tighten the battery retainers on all machines at every 1000 hour interval.

Clean the top of the batteries with a clean cloth at every 1000 hour interval or more often, if necessary. Keep the terminals clean and coat the terminals with petroleum jelly.

Each battery cell should not require more than 30 cc (1 oz) of water weekly. This usage of water is typical with the proper charging rate and with a moderate climate.

When you are operating the machine in extreme temperatures, check the water in the battery cells weekly.
