INSPECTION/SETUP
CLEANING THE RADIATOR
The engine may overheat if the radiator fi ns become
overloaded with dust or debris. Periodically clean the
radiator fi ns with compressed air. Cleaning inside the
machine is dangerous, so clean only with the engine turned
off and the negative battery terminal disconnected.
AIR CLEANER
Periodic cleaning/replacement is necessary. Inspect it in
accordance with the KUBOTA Engine Owner’s Manual.
Fan Belt Tension
A slack fan belt may contribute to overheating, or to
insuffi cient charging of the battery. Inspect the fan belt
for damage and wear and adjust it in accordance with the
Kubota Engine Owner's Manual.
The fan belt tension is proper if the fan belt bends 10 to 15
mm (Figure 12) when depressed with the thumb as shown
below.

terminal treatment compound. Replace battery with only
recommended type battery.
The battery is suffi ciently charged if the specifi c gravity
of the battery fl uid is 1.28 (at 68° F). If the specifi c gravity
should fall to 1.245 or lower, it indicates that the battery is
dead and needs to be recharged or replaced.
Before charging the battery with an external electric source,
be sure to disconnect the battery cables.
