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).
d. Recharge battery when ever the specific
gravity value is less than 1.225
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:
Note:
For E.F.I. Tanks, the battery must be
disconnected (Negative lead) for storage
exceeding four weeks. Do not “Jump Start” an
E.F.I. unit, recharge or replace battery to avoid
damage to the Electronic Control Unit (ECU).
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.
