Cleaning the Radiator, AIR Cleaner, Battery

INSPECTION/SETUP

NOTICE

When the antifreeze is mixed with water, the antifreeze mixing ratio must be less than 50%.

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 insufﬁcient 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.

BATTERY

This unit is of negative ground DO NOT connect in reverse. Always maintain battery ﬂuid level between the speciﬁed marks. Battery life will be shortened, if the ﬂuid level are not properly maintained. Add only distilled water when replenishment is necessary.

DO NOT over fill. Check to see whether the battery cables are loose. Poor contact may result in poor starting or malfunctions. Always keep the terminals firmly tightened. Coating the terminals with an approved battery terminal treatment compound. Replace battery with only recommended type battery.

The battery is sufﬁciently charged if the speciﬁc gravity of the battery ﬂuid is 1.28 (at 68° F). If the speciﬁc 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.

Battery Cable Installation

ALWAYS be sure the battery cables (Figure 13) are properly connected to the battery terminals as shown below. The red cable is connected to the positive terminal of the battery, and the black cable is connected to the negative terminal of the battery.

CAUTION

ALWAYS disconnect the negative terminal FIRST and reconnect negative terminal LAST.
