Danger:
Read General Safety Precautions Nos. 9 and 10.
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.
c. Store the battery with a full charge. A dis-
charged battery will freeze (refer to the
table below).
d. Recharge battery when ever the specific
gravity value is less than 1.225
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

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 bat-
tery.
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.

between the ignition and start switch and
other electrical components. This is a stan-
dard plug-in type automotive fuse rated at 7.5
amp.
