Electrical System
Battery Storage
If the machine will be stored for more than 30 days:
1. Remove the battery from the machine and charge it
fully (see Battery Service).
2. Either store battery on a shelf or on the machine.
3. Leave battery cables disconnected if the battery is
stored on the machine.
4. Store battery in a cool atmosphere to a void quick de-
terioration of t he battery charge.
5. To help prevent the battery from freezing, make sure
it is fully charged (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.
Wear safety goggles and rubber gloves when
working with electrolyte. Charge battery in a well
ventilated place so gasses produced while
charging can dissipate. Since the gases are ex-
plosive, keep open flames and electrical sparks
away from the battery; do not smoke. Nausea
may result if the gases are inhaled. Unplug char-
ger from electrical outlet before connecting or
disconnecting charger leads to or from battery
posts.
CAUTION
IMPORTANT: Do not remove battery fill caps while
cleaning.
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. Coat battery posts and cable connectors with
Battery Terminal Protector (Toro Part No. 107--0392)
or petroleum jelly to prevent corrosion.
3. Battery cables must be tight on terminals to provide
good electrical contact. Tighten nuts that secure battery
cables from 10 to 15 ft--lb (14 to 20 N--m).
Connecting battery cables to the wrong bat-
tery post could result in personal injury a nd/or
damage to the electrical system.
CAUTION
4. If corrosion occurs at battery terminals, disconnect
cables. Always disconnect negative (--) cable first.
Clean clamps and terminals separately. Reconnect
cables to battery with positive (+) cable first. Coat bat-
tery posts and cable connectors with Battery Terminal
Protector (Toro Part No. 107--0392) or petroleum jelly to
prevent corrosion.
5. Periodically (at least every 50 operating hours)
check battery electrolyte level. Check electrolyte level
every 30 days if machine is in storage.
6. Maintain battery cell level with distilled water. Do not
fill battery cells above the fill line.
