Service and Repairs
NOTE: Refer to the appropriate engine Service Manual
for engine electrical component repair information.
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 avoid quick de-
terioration of the 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 explosive, keep open flames and electrical
sparks away from the battery; do not smoke.
Nausea may result if the gases are inhaled. Un-
plug battery charger from electrical outlet be-
fore connecting or disconnecting charger
leads to or from battery posts.
CAUTION
IMPORTANT: Do not remove battery fill caps while
cleaning battery.
2. Check battery condition weekly or after every fifty
(50) hours of operation. Keep terminals and entire bat-
tery 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 Bat-
tery 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.
Connecting battery cables to the wrong battery
post could result in personal injury and/or dam-
age to the electrical system.
CAUTION
4. If corrosion occurs at battery terminals, disconnect
cables. Always disconnect negative (−) cable first. Clean
clamps and terminals separately. Connect cables to bat-
tery with positive (+) cable first. Coat battery posts and
cable connectors with Battery Terminal Protector (Toro
Part No. 107−0392) or petroleum jelly to prevent corro-
sion.
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.
