Day-to-day addition of coolant is done from the
Operation in Freezing Weather
When operating in freezing weather, be certain that the proper
amount of antifreeze has been added.See Table 9. for anti-
freeze operating temperatures.
Day-to-day addition of coolant or anti-freeze is done from
the reserve tank. See Table 8. for engine, radiator and reserve
tank coolant capacities. Make sure that the coolant level in
the reserve tank is always between the "H" and the "L"
markings.
Cleaning the Radiator
The radiator may overheat if the fins become overloaded
with dust or debris. Periodically clean the radiator fins with
compressed air. Cleaning inside the machine is dangerous,
so clean only with the engine turned off.
Fan Belt Tension
A slack fan belt may contribute to overheating, or to
insufficient charging of the battery. Inspect and adjust it in
accordance with the KUBOTA engine manual.
The fan belt tension is proper if the fan belt (Figure17) bends
7 to 9 mm (0.28- to 0.35 in.) when depressed with the thumb
as shown in Figure 16 below.
When the anti-freeze is
mixed with water, the anti-
freeze mixing ratio must
be less than 50%.
Air Cleaner
Periodic cleaning/replacement is necessary. Inspect it in
accordance with the engine manual.
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 is not
properly maintained. Add only distilled water when
replenishment is necessary.
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.
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 a thin film of grease will help to inhibit corrosion.
The battery gradually deteriorates over time. The actual life
span will vary according to operating conditions, but generally
a battery two years or older should be replaced.
