BATTERYCAREAND MAINTENANCE
CHECK FLUID LEVEL
Check fluid level inside each cell of the battery every
two weeks and before and after charging. Always
keep level between the LOWER LEVEL and UPPER
LEVEL lines on battery.
Add only distilled water. Never add additional acid
or any other chemicals to the battery after initial acti-
vation.
NOTE: After operating the lawn tractor for a long peri-
od of time, check the fluid level in the battery as ff can
overheat and lose fluid.
CHARGING THE BATTERY
The engine is equipped with an alternator which
charges battery when tractor is operated. Under nor-
mal conditions, the battery only needs to be charged
before, during and after off-season storage. Follow
the instructions under "Off-Season Storage."
To charge the battery: Make certain fluid level in
each cell is between LOWER LEVEL and UPPER
LEVEL. Use a 12 volt automotive charger which is
rated less than 10 amps.
Lawn Tractors with Single Cylinder Engines: Charge
for 14 to 16 hours. DO NOT CHARGE LONGER
THAN 30 HOURS.
Lawn Tractors with Twin Cylinder Engines: Charge for
a minimum of 3 hours and a maximum of 5 hours.

itive terminal of the good battery, then the other
end to the positive terminal of the dead battery.

washing with a baking soda and water solution. If nec-
essary, scrape the battery terminals with a wire brush
to remove deposits. Coat terminals and exposed wiring
