Greensmaster 3320/3420 Page 6 − 75 Electrical System
12 Volt Battery Care
1. Battery electrolyte level must be properly main-
tained. The top of the battery must be kept clean. lf the
machine is stored in a location where temperatures are
extremely high, the battery will discharge more rapidly
than if the machine is stored in a location where temper-
atures are cool.
WARNING
Wear safety goggles and rubber gloves when
working with battery electrolyte. Charge battery
in a well ventilated place so gasses produced
while charging can dissipate. Since the gases
are explosive, keep open flames and electrical
sparks away from the battery; do not smoke.
Nausea may result if the gases are inhaled. Un-
plug charger from electrical outlet before con-
necting or disconnecting charger leads to or
from battery posts.
2. Keep top of battery clean by washing periodically
with a brush dipped in baking soda (sodium bicarbon-
ate) solution. Flush top surface with water after clean-
ing. Do not remove the fill caps while cleaning.
3. Battery cables must be tight on battery terminals to
provide good electrical contact.
WARNING
Connecting battery cables to the wrong battery
post could result in personal injury and/or dam-
age to the electrical system.
4. If corrosion occurs at battery terminals, disconnect
battery cables. Always disconnect negative (−) cable
first. Clean cable clamps and terminals separately. Re-
connect battery cables with positive (+) cable first. Coat
terminals with battery terminal protector (see Special
Tools in this chapter) or a light coat of grease to reduce
corrosion after connections are made.
5. Check battery electrolyte level every twenty five (25)
operating hours and every thirty (30) days if machine is
in storage.
6. Maintain battery cell level with distilled or demineral-
ized water. Do not fill cells above the fill line.
12 Volt Battery Storage
If the machine will be stored for more than thirty (30)
days:
1. Make sure ignition switch is in the OFF position. Re-
move the battery and charge it fully (see Battery Service
in this section).
2. Either store battery on a shelf or on the machine.
3. Leave cables disconnected if the battery is stored on
the machine.
4. Store battery in a cool atmosphere to avoid quick de-
terioration of the battery charge.
5. To help prevent the battery from freezing during stor-
age, make sure it is fully charged (see Battery Service
in this section).
