Service and Repairs
NOTE: For engine component repair information, see
the Kubota Workshop Manual, Diesel Engine,
V2403--M--T--E3B Series at the end of Chapter 3 -- Ku-
bota 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 s ection).
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 explosive, keep open flames and electrical
sparks away from the battery; do not smoke.
Nausea may result ifthegasesare inhaled. Un-
plug charger from electrical outlet before con-
necting 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 with a solu-
tion ofbakingsoda and water. Rinse with clear water.
B. Coatbattery posts andcable 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 post
could result in personal injury and/or damage
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
connectorswithbattery terminalprotector(Toro PartNo.
107--0392) or petroleum jelly to prevent corrosion.
5. Checkelectrolytelevelevery 25 operating hours and
every 30 days if machine is in storage.
6. Maintain cell level with distilled water. Do not fill cells
above the fill line.
