CHECK POINTS AFTER STARTING THE
ENGINE
After starting the engine, but before starting operation,
check the following points:
1. Put the throttle potentiometer in the middle between
" " and " " symbols and let the engine idle for
approx. five minutes. This allows the engine lubricant
to warm up and penetrate every part of the engine.
2. Once the engine has warmed up, check:
A the warning lamp "Engine oil pressure" has gone
out.
A the warning lamp "Battery charge" goes out when
engine speed is increased.
A the color of the exhaust is normal and no abnormal
noises or vibrations are heard or felt.
A no fluid is leaking from pipes or hoses.
C Should any following conditions occur, stop the
engine immediately.
A The engine rpm's increases or decreases suddenly.
A Sudden abnormal noises are heard.
A Exhaust is black.
A Warning lamp for engine oil lights up during operation.
A In these cases, the excavator must be checked and
serviced by your local the KUBOTA dealer.
STOPPING THE ENGINE
To avoid personal injury or death:
A Do not keep the bucket or dozer in an elevated
position, as a person could accidentally touch
the levers and cause serious accidents.
BEngine Stop Button

BPrecautions in case of Overheat
To avoid personal injury:
A Do not open the radiator cap during operation
or just after shut-down. Otherwise, steam or
very hot coolant may gush out, getting you
scalded. Make sure the radiator has cooled
down enough before opening its cap.
If by any chance the coolant temperature rises close to or
above the boiling point ("H" on the water temperature
gauge) (overheat condition), take the following steps.
1. Stop operating the machine.
(Relieve the engine of any load.)
2. Do not shut off the engine suddenly. Before shutting
off the engine, keep it idling under no load for about 5
minutes.
3. Stay away from the engine or overflow for 10 minutes
or until the steam overflow stops.
4. Be sure that there is no danger of getting scalded.
Pinpoint and remove the cause of overheat, referring
to the "TROUBLESHOOTING" section. Once the
issue is resolved, the engine may be restarted.

ground.
