Battery Storage
If the machine will be stored for more than 30 days:
1. Remove the battery and charge it fully (see Battery
Service).
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, make sure
it is fully charged before storing the battery/machine
(see Battery Service).
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.
working with electrolyte. Charge battery in a
well ventilated place so gasses produced
while charging can dissipate. Since the gases

WARNING
Wear safety goggles and rubber gloves when
are explosive, keep open flames and electrical
sparks away from the battery; do not smoke.
Nausea may result if the gases are inhaled. Un-
IMPORTANT: Do not remove battery filler caps
while cleaning battery.
2. Check battery condition weekly or after every 50
hours of operation. Keep terminals and entire battery
case clean because a dirty battery will discharge slowly.
A. Clean battery by washing entire case with a solu-
tion of baking soda and water. Rinse with clear water.
B. Spray battery terminals with Battery Terminal
Protector (Toro Part No. 107–0392) to prevent cable
and terminal corrosion. Petroleum jelly can be used
as well.
3. Battery cables must be tight on terminals to provide
good electrical contact.
could result in personal injury and/or damage
to the electrical system.
WARNING
Connecting cables to the wrong battery post
4. If corrosion occurs at terminals, disconnect cables.
Always disconnect negative (–) cable first. Clean
clamps and terminals separately. Reconnect cables
with positive (+) cable first. Coat battery posts and cable
connectors with Battery Terminal Protector (Toro Part
No. 107–0392) or petroleum jelly to prevent corrosion.
5. Check electrolyte level every 25 operating hours,
and every 30 days if machine is in storage.
6. Maintain cell electrolyte level with distilled or demin-
eralized water. Do not fill cells above the fill line.
