Danger:

Read General Safety Precautions Nos. 9 and 10.

1.Battery: The battery is located beneath the operator’s seat. Remove the fillcaps and check the level of the liquid electrolyte 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 out- side 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 termi- nals with petroleum jelly to prevent corrosion.

2.Battery Storage: When storing the Mower for long periods of time the following guidelines should be taken.

a.Disconnect the battery cables from the ter- minals and remove the battery. You will have to remove the control panel to access the battery strap. Replace control panel.

b.Clean the battery before storing. A dirty battery will lose its charge over time.

c.Store the battery with a full charge. A dis- charged battery will freeze (refer to the table below)..

3.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.

4.Installing the Battery

Note: The battery is delivered from the fac- tory fully charged and filled with electrolyte.

a.Attach the Positive (red) cable.

b.Attach the Negative (black) cable.

c.Attach the rubber battery strap.

5.Jump Starting

Warning:

Failure to use this starting procedure can cause sparking, and the gases in the battery to explode.

a.Attach the end of the red jumper cable to the Positive terminal (+) of the charged battery.

b.Attach the other end of the red jumper cable to the Positive terminal (+) of the low charge battery.

c.Attach the end of the black jumper cable to the Negative terminal of the charged bat- tery.

d.Attach the other end of the black jumper cable to the frame of the unit with the low charge battery.

6.Fuses: There is one fuse located in the wiring between the ignition and start switch and
