Service and Repairs
NOTE: For engine component repair information (e.g.
starter motor), see the Kubota Workshop Manual, Die-
sel Engine, 03--M--E3B Series at the end of Chapter 3
-- Kubota Diesel Engine.
Battery Storage
If the machine will be stored for more than 30 days:
1. Remove 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 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 in this section).
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 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 thegases areinhaled. Unplug char-
ger from electrical outlet before connecting or
disconnecting charger leads to or from battery
posts.
IMPORTANT: Do not remove fill caps while clean-
ing.
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 w ith a solu-
tion of baking soda and water. Rinse with clearwater.
B. Coatbattery posts and cable connectors withbat-
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.
WARNING
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
connectorswithbatteryterminalprotector (ToroPartNo.
107--0392) or petroleum jelly to prevent corrosion.
5. Check electrolyte level every25 operatinghours and
every 30 days if machine is in storage.
6. Maintain cell level with distilled water. Do not fill cells
above the fill line.
