CHARGING A MAINTENANCE
FREE BATTERY
NOTE
Remove battery from tractor.
1. Be sure charger is “Off”.
2. Connect charger leads to battery. Connect the pos-
itive (+) connector from the charger to the positive
battery terminal. Connect the negative (–) connec-
tor of the charger to the negative battery terminal.
3. Charge the battery using one of the methods shown
below. Follow the manufacturer’s instructions on
the charger.
4. If, when charging the battery, violent gassing or
spewing of electrolyte occurs, or the battery case
feels hot, 125°F (52°C), reduce or temporarily halt
charging to avoid damaging the battery.
5. Always turn charger to “Off” before removing a
charger lead from the battery.
MAINTENANCE/CLEANING
A buildup of corrosive acid across the top of the battery
can cause the battery to self-discharge. Even a light
coating of this grayish-white substance can complete
a circuit to drain and exhaust the energy in the bat-
tery. This is especially bad when moisture is present.
To maintain a battery in top condition, check and per-
form the following services at frequent intervals:
1. Regularly check level of electrolyte — add water
as necessary to maintain level above plates — do
not overfill as this can cause poor performance or
early failure due to loss of electrolyte.
2. Keep terminals and top of battery clean. Wash with
baking soda and rinse with clear water. Do not al-
low soda solution to enter cells as this will destroy
the electrolyte.
3. Make sure battery terminals are tight and cables
are in good condition.

WARNING
Batteries contain sulfuric acid and generate ex-
plosive mixtures of hydrogen and oxygen gases.
Keep any device which may cause sparks or
flames away from the battery to prevent explosion.
!
WARNING
Always wear protective glasses or goggles and
protective clothing when working with batteries.
You must follow the battery manufacturer’s in-
structions on safety, maintenance and installa-tion
procedures.
!
CAUTION
Always connect the “ground” (black) cable last
and remove it first whenever performing any bat-
tery maintenance. When the battery is being
removed or reinstalled, make sure the positive
and negative terminals do not contact metal
tractor parts at the same time or arcing will re-
sult. Battery connections must be kept clean and
tight at all times. Loose cables will cause arcing
and pitting of the connections and cause eventu-
al failure. Keep positive terminal cover in place.
!
WARNING
To avoid possible injury, stand away from battery
when the charger is turned on. A damaged bat-
tery or a battery with an internal short could
explode.
