Charging Wet Batteries

Charge the batteries each time the machine is used, or when the Battery Indicator (D2) is reading less than full.
Warning!
• Do not fill the batteries before charging.
• Charge batteries in a well-ventilated area.
• Do not smoke while charging the batteries.

When Servicing Wet 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:

1. Turn the Key Switch (A) OFF.
2. Unwind the electrical cord from the side of the onboard charger and plug it into a properly grounded outlet. Refer to
the OEM product manual for more detailed operating instructions.

If your machine shipped without an onboard battery charger, do the following:

1. Disconnect the batteries from the machine and push the connector from the charger into the Battery Pack
Connector (17).
2. Follow the instructions on the battery charger.
Service Note: Make sure you plug the battery charger into the connector with the handle attached to it.
Caution!
To avoid damage to floor surfaces, wipe water and acid from the top of the batteries after charging.

Checking the Battery Water Level

1. Check the water level in the batteries at least once a week.
2. After charging the batteries, 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 10 mm over the top of the separators). DO NOT overfill the batteries!
