Maintenance and Adjustments
Charging Batteries
Caution!
• Charge batteries in a well-ventilated area.
• Do not smoke while servicing the batteries.
• Remove all jewelry
• Wear safety glasses, rubber gloves and a rubber apron
• Do not allow tools to touch more than one battery terminal at a time
• To avoid damage to floor surfaces, wipe water and acid from the top of the batteries after
charging.
If your machine shipped with an onboard battery charger, turn the Key Switch off. Unwind the electrical
cord from the side of the onboard charger and plug it into a properly grounded outlet. Conrm that the
correct charging prole is in use. Refer to the OEM product manual for more detailed operating instructions.
If your machine uses an external battery charger, unplug the battery connector (1) from the machine
connector (2), and plug the battery connector (1) into the charger. Follow the instructions on the battery
charger.
Extending Battery Life
Proper maintenance of electric vehicle batteries can greatly extend their life. The following information will
help extend the life of your batteries.
• Your battery will deliver superior performance and life if it is recharged properly. Excessive charging
or discharging will shorten battery life and limit performance. Be sure to follow proper charging
instructions.
• Make sure you have an appropriate charger for the type of battery. Use only “voltage-regulated” or
“voltage-limited” chargers. Standard constant-current or taper current chargers must not be used. A
temperature-sensing charger is recommended.
• Important! Do not attempt to open sealed gel batteries or add water. Doing so will damage the battery
and void the warranty.
• For wet batteries, maintain proper electrolyte level and check weekly. Use distilled water in batteries
whenever possible. If the batteries are discharged, add just enough water to cover the plates in each cell,
and recheck the level after charging (this prevents over-lling the battery). If batteries are fully charged,
ll each cell to the bottom of the ller tube. Do not over-ll the batteries! Do not add acid to batteries!
• Keep the batteries charged. Batteries should be charged each time that a machine is used for more than 1
hour. Machine operators should open the battery compartment cover for charging, to avoid a concentrated
build-up of hydrogen gas. Operators should follow the instructions provided with their specic battery
charger, to determine how long the batteries should be charged. Even when a machine is stored, the
batteries should be charged once a month to prevent the batteries from “sulfating”. Most battery caps are
vented, so there’s no need to loosen or remove them for charging.
• Keep the batteries clean. Use a damp cloth to wipe dirt from the top of the batteries. Battery terminals
must be clean and tight. If the tops of the batteries are wet after charging, the batteries have probably
been overlled or over-charged. Note: If there is acid on the batteries, wash the tops of the batteries with
a solution of baking soda and water (2 tablespoons of baking soda to 1 quart of water).
