RADIATOR CLEANING
The radiator (Figure 67) should be sprayed (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 in order to access the radiator for cleaning.

DRIVE BELT (DAILY)
Drive Belt Tension
A slack drive belt (Figure 68) may contribute to overheating
or insufficient charging of the battery. Adjust the drive belt
in accordance with the Kubota engine operator's manual.
Drive Belt Inspection
Inspect the drive belt for damage and wear. Horizontal
cracks (across the belt) are acceptable. Vertical (direction
of belt ribs) cracks 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.

below fails. Consult a qualified electrician for repair or
replacement of the GFCI receptacle. Test the GFCI
receptacle at least once a month.
1. Start the generator as outlined in the start-up procedure
in this manual.
2. Place a GFCI circuit breaker (Figure 69) in the ON
position.
