Easy Checker lamps
Engine oil pressure
warning indicator
If the oil pressure in the engine goes below
the prescribed level, the engine oil-pres-
sure-warning indicator in the Easy Checker
will come on.
If the engine oil-pressure-warning indicator
should come on during operation of the
tractor, and this warning-indicator lamp
does not go off when the engine is acceler-
ated to more than 1000 rpm, check level of
engine oil.
(See Checking the engine oil level on page
103)
Electrical charge
warning indicator
If the alternator is not charging the battery,
the electrical charge-warning indicator in
the Easy Checker will come on.
If the electrical charge-warning indicator
should come on during operation of the
tractor, check the electrical-charging sys-
tem or consult your local Kubota Dealer.

Engine warning in-
dicator
Engine-warning indicator serves the follow-
ing 2 functions. If the engine-warning indi-
cator lights up, pinpoint the cause and take
a proper measure. At same time, error
code might also appear.
Error with the engine-control sys-
tem
If during operation the water-tempera-
ture gauge reads an acceptable level
but the engine-warning indicator in the
Easy Checker comes on, stop the en-
gine and get it restarted. If the error
happens again, consult your local Ku-
bota Dealer.
IMPORTANT :
If the engine-warning indicator
lights up, the following phe-
nomena may appear depend-
ing on the trouble spot of the
engine:
Engine stops unexpected-
ly.
Engine fails to start or
gets interrupted just after
start.
Engine output is not
enough.
Engine output is enough,
but the engine-warning in-
dicator stays on.
If the engine output is not enough, im-
mediately interrupt the operation and
move the tractor to a safe place and
stop the engine.
Engine overheat
If the water-temperature gauge reads
an unusual level and the engine-warn-
ing indicator in the Easy Checker
comes on, the engine may have got
overheated. Check the tractor accord-
ing to ENGINE TROUBLESHOOTING
on page 133.
Emission indicator
If the emission indicator lights up, take the
steps to lower the water temperature. Low-
ering the water temperature helps keep the
emission clean.
Master system
warning
If trouble should occur at engine, transmis-
sion, or other control parts, the master-sys-
tem-warning indicator flashes as a warning.
At same time, error code will appear. If the
trouble is not corrected by restarting the
tractor, consult your local Kubota Dealer.
NOTE :
For checking and servicing of your tractor,
consult your local Kubota Dealer for
instructions.
Error code will not disappear even if the
warning indicator is reset.
