9OPERATION OF THE ENGINE
BHourmeter
The hourmeter shows the total operating hours
of the excavator.
C Meter reading
The meter counts up 1 for one operating hour.
The electric meter is still counting if the engine
stops but the key is in the "ON" position.
BCheckpoints after Starting the
Engine
After starting the engine, but before starting
operation, check following points:
1. Put the throttle lever in the "LOW" position
and let the engine idle for approx. 5 minutes.
This allows the engine lubricant to warm up
and penetrate every part of the engine.
A This idling is usually called "Warm-up".
2. Once the engine has warmed up, check:
A the alarm lamp "Engine oil pressure" has
gone out.
A the alarm lamp "Battery charge" goes out
when accelerating the engine.
A the colour of the exhaust gas 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 arise,
stop the engine immediately.
A The engine revolution increases or
decreases suddenly.
A Sudden abnormal noises.
A Exhaust gas is black.
A Alarm lamp for engine oil lights up during
operation.
A In these cases, the excavator must be
checked and serviced according to the
directions of the KUBOTA dealer.
STARTING THE ENGINE UNDER
COLD CONDITIONS
To avoid personal injury:
A Make sure that the lock lever is in the
lock position during warm up.
Start the engine in the following manner;
1. Pull the throttle lever completely all the way
back.
2. Turn the key to the "PREHEAT" position.
(approx. 10 sec.)
3. Turn the key to the "START" position; the
engine will start.
4. Release the key after the engine has
started; it will automatically return to the
"ON" position.
A Let the engine warm up after start-up.
A Let the engine warm up after start-up for
approx. 10 minutes under no load
conditions. If the hydraulic fluid temperature
is too low, the operation will be affected.
Do not operate the excavator under full load
before the engine is warmed up enough.
