CHARGING WET LEAD-ACID BATTERIES
Charge the batteries each time the machine is used or when the Battery Charge Level Indicator (C3) is reading less than full.
WARNING!
Do not top off the batteries before charging. Check to ensure the plates are covered only.
Charge batteries in a well-ventilated area. If battery acid makes contact with your skin, flush the affected area with water for 5 minutes
and seek medical attention.
Do not smoke while servicing the batteries.
When Servicing Batteries...
* Remove all jewelry
*
Do not smoke
* Wear safety glasses, rubber gloves and a rubber apron
* Work in a well-ventilated area
* Do not allow tools to touch more than one battery terminal
at a time
* ALWAYS disconnect the negative (ground) cable first when
replacing batteries to prevent sparks.
*
ALWAYS connect the negative cable last when installing
batteries.
If your machine shipped with an onboard battery charger
do the following:
Turn the machine off at the Power Switch (H).
1
2 See Figure 4-4. Tip the seat forward (gas spring holds
the seat open) for battery, charger access and proper
ventilation.
3 Unwind the electrical cord (18A) for the onboard charger
and plug it into a properly grounded outlet. Refer to
the OEM product manual for more detailed operating
instructions. While AC power is applied to the onboard
charger all machine functions are disabled.
The Battery Charge Status Indicator (C3) will begin showing the batteries' state of charge. This indicates that the charging cycle has begun. As the charging
4
cycle continues, the battery charge level will fill in.
5 When the Battery Charge Status Indicator (C3) is completely filled, the machine senses fully charged batteries, however the charging process may not be
complete. Rely on the status lights on the Charger (18) (and its OEM manual) to verify when the batteries are completely charged. This may take several
hours depending upon the condition of the batteries before charging.
6 After charging is complete unplug the charger and wind up the Cord (18A). Wait at least 10 seconds before turning on the machine after unplugging the
charger.
If your machine shipped without an onboard battery charger do the following:
1 Turn the machine off at the Power Switch (H).
See Figure 4-4. Tip the seat forward for battery access and proper ventilation, gas spring holds seat open.

3 Disconnect the batteries from the machine and push the connector from the charger into the Machine Battery Connector (19). Follow the instructions on the
battery charger and OEM product manual. SERVICE NOTE: Make sure you plug the battery charger into the connector that attaches to the batteries.
CAUTION!
To avoid damage to floor surfaces, wipe water and acid from the top of the batteries after charging. Under or overcharging will
shorten battery life and limit performance. Be sure to FOLLOW PROPER CHARGING INSTRUCTIONS!
CHECKING THE BATTERY WATER LEVEL
After charging, check the water level of the batteries at least once a week.
Remove the vent caps and check the water level in each battery cell. Use distilled or demineralized water in a battery filling dispenser (available at most auto parts
stores) to fill each cell to the level indicator (or to .39 inches / 10 mm over the top of the separators). DO NOT over-fill the batteries! Reinstall vent caps.
CAUTION!
Acid can spill onto the floor if the batteries are overfilled.
Tighten the vent caps. Wash the tops of the batteries with a solution of baking soda and water (2 tablespoons of baking soda to 1 liter of water).
