1.Battery: The battery is located beneath the operator’s seat. If so equipped, remove the fill- caps and check the level of the liquid electro- lyte in the battery every 50 operating hours. If the level in any of the six cells has dropped below the bottom of the split ring inside the fill hole, refill the cell with distilled water. To keep the outside of the battery clean, brush on a strong solution of bicarbonate of soda and water and rinse with clean water. Keep the contacts and cable ends clean with a wire brush and make sure the connections are tight. Coat the terminals with petroleum jelly to prevent corrosion.
2.Battery Removal
Warning:
When removing the cables from the battery follow these steps to avoid a short between the wrench and the frame.
a.Remove the negative (black) cable.
b.Remove the positive (red) cable.
c.Release the hold down straps.
d.Remove the battery without tipping.
3.Battery Storage: When storing the mower for long periods of time the following guidelines should be performed.
a.Disconnect the battery cables from the ter- minals and remove the battery.
b.Clean the battery before storing. A dirty battery will lose its charge over time.
