Service and Repairs
NOTE: For additional electrical component service and
repair information, see the Kubota Workshop Manual for
05 Series Diesel Engines, or the Kubota Workshop and
Diagnostics Manuals for WG972 Gasoline Engines.
Battery Care
1. The top of the battery must be kept clean. lf the ma-
chine is stored in a location where temperatures are ex-
tremely 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 (if equipped)
while cleaning the battery.
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 (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
connectors with battery terminal protector (Toro Part No.
107−0392) or petroleum jelly to prevent corrosion.
5. If the battery electrolyte is accessible, check electro-
lyte level every 25 operating hours and every 30 days if
machine is in storage. Maintain cell level with distilled
water. Do not fill cells above the fill line.
