OPERATING THE ENGINE
ENGLISH
B
Hour Meter
This meter gives readings for the hours the machine has
been operated for.
A
As the hour meter works electrically, it starts to work
when the key switch is turned to "ON", regardless of
the engine running or not.
COLD WEATHER STARTING
When the ambient temperature is below -5
(23
) and
the engine is very cold. (If the engine fails to start after 10
seconds, turn off the key for 30 seconds. Then repeat
steps 8, 9 and 10. To protect the battery and the starter,
make sure that the starter is not continuously turned for
more than 30 seconds.)
BLOCK HEATER (OPTION)
A block heater is available as an option from your local
dealer. It will assist you in starting your machine when the
ambient temperature is below freezing.
WARMING UP
To avoid personal injury:
A
Be sure to apply the parking brake during
warm-up.
For 5 minutes after engine start-up, allow the engine to
warm up without applying any load. This is to allow oil to
reach every engine part. If load should be applied to the
engine without this warm-up period, the troubles such as
seizure, breakage or premature wear may develop.
B
Warm-up and Transmission Oil in the Low
Temperature Range
Hydraulic oil serves as transmission oil. In cold weather,
the oil may be cold with increased viscosity. This can
cause delayed oil circulation or abnormally low hydraulic
pressure for some time after engine start-up. This in turn
can result in a trouble in the hydraulic system or a damage
to the hydraulic clutch.
To prevent the above, observe the following instructions:
Warm up the engine at about 50% of rated rpm according
to the table below:
A
Do not operate unless the engine is well warmed up. If
operation is attempted while the engine is still cold, the
hydraulic mechanism will not function properly and its
service life will be shortened.
A
If noises are heard after the hydraulic control lever has
been activated and the implement is lifting, the
hydraulic mechanism is not adjusted properly. Unless
corrected, the unit will be damaged. Contact your local
KUBOTA Dealer for adjustment.
