Service and Repairs
NOTE: For engine component repair information, see
the Yanmar Model 4TNV86CT−DTR Service Manual or
Troubleshooting Manual, or the Kubota Model
03−M−DI−E3B Workshop Manual.
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 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 the gases are inhaled. 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 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 (see Special Tools in this
chapter) or petroleum jelly to prevent corrosion.
3. Battery cables must be tight on battery terminals to
provide good electrical contact.
Connecting cables to the wrong post could re-
sult in personal injury and/or damage to the elec-
trical system.
WARNING
4. If corrosion occurs at battery terminals, disconnect
cables. Always disconnect negative (−) cable first.
Clean clamps and terminals separately. Reconnect
cables with positive (+) cable first. Coat battery posts
and cable connectors with battery terminal protector
(see Special Tools in this chapter) 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 battery cell level with distilled or demineral-
ized water. Do not fill cells above the fill line.
