Battery

Your mower is equipped with a maintenance free battery and does not need servicing. However, periodic charging of the battery with an automotive type battery charger will extend its life.

Keep battery and terminals clean.

Keep battery bolts tight.

Recharge at 6-10amperes for 1 hour

To clean battery and terminals

Corrosion and dirt on the battery and terminals can cause the battery to “leak” power.

1.Open the terminal access doors.

2.Disconnect BLACK battery cable first, then the

RED battery cable and remove the battery from the machine.

3.Rinse the battery with plain water and dry.

4.Clean terminals and battery cable ends with wire brush until shiny.

5.Coat terminals with grease or petroleum jelly

6.Reinstall battery.

Replacing battery

1.Lift seat and rotate forward.

2.Remove the red terminal guard.

3.Using two ½" wrenches disconnect BLACK battery cable then RED battery cable.

4.Using a 7/16" wrench, remove the terminal guard.

5.Carefully remove the battery from the mower.

6.Install new battery with terminals in the same position as the old battery.

7.Reinstall the terminal guard.

8.First connect RED battery cable to positive (+) battery terminal with hex bolt and hex nut.

9.Connect BLACK grounding cable to negative (-)battery terminal with remaining hex bolt and hex nut.

10.Tighten securely.

11.Close terminal access door.

12.Lower seat.

Always use protective glasses when handling the battery.

IMPORTANT INFORMATION

Do not attempt to open or remove caps or covers. Adding or checking level of electrolyte is not necessary.

Always use two wrenches for the terminal screws.

WARNING!

Do not short battery terminals by allowing a wrench or any other object to contact both terminals at the same time. Before connecting battery, remove metal bracelets, wristwatch bands, rings, etc.

Positive terminal must be connected first to prevent sparks from accidental grounding.
