Service and Repairs
NOTE: See the Kubota Workshop Manual, Diesel En-
gine, 05--E3B Series at the end of Chapter 3 -- Kubota
Diesel Engine for engine electrical component repair in-
formation.
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 in this section).
2. Either store battery on a s helf 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 (see Battery Service in this s ection).
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 thegases are inhaled.Un-
plug charger from electrical outlet before con-
necting 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.
Connecting battery cables to the wrong bat-
tery post could result in personal injury and/or
damage to the electrical system.
CAUTION
4. If corrosion occurs at terminals, disconnect cables.
Always disconnect negative (--) c able 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 level with distilled or demineralized wa-
ter. Do not fill cells above the fill line.
