RADIATOR CLEANING
The radiator (Figure 49) should be spray-cleaned with
a high-pressure washer when excessive amounts of dirt
and debris have accumulated on the cooling fins or tube.
When using a high-pressure washer, stand at least 5 feet
(1.5 meters) away from the radiator to prevent damage to
the fins and tube.
NOTICE
It may be necessary to remove additional generator
components to access the radiator for cleaning.

DRIVE BELT
Drive Belt Tension
A slack drive belt may contribute to overheating or
insufficient charging of the battery. Adjust the drive belt in
accordance with the Kubota engine owner's manual.
Drive Belt Inspection
Inspect the drive belt (Figure 50) for damage and wear.
Horizontal cracks (across the belt) are acceptable. Vertical
cracks (direction of belt ribs) that intersect with horizontal
cracks are not acceptable.
Also, examine the belt and determine if it is oil soaked or
glazed (a hard shiny appearance on the sides of the belt).
Either of these two conditions can cause the belt to run hot,
which can weaken it and increase the danger of it breaking.
If the drive belt exhibits any of the above wear conditions,
replace the drive belt immediately.
