OPERATION OF THE ENGINE
4. Check if all warning indicators except parking-
brake-indicator have gone out. If a warning indicator
still should be lit up, stop the engine then remove
the starter key and check for the cause.
IMPORTANT :
• The starter motor consumes large current.
Avoid running the starter motor longer than
10 seconds continuously.
If the engine fails to start within 10 seconds,
once set the starter key to the [STOP]
position, wait for 20 seconds or longer, and
repeat the same steps.
• If the battery is dead and must be connected
to another battery with jumper cable, be sure
to use a 12V battery. Never use any
24V batteries.
NOTE :
• When the auxiliary-port-lever or the shuttle-
change-lever is not in the neutral position,
or the parking-brake-switch not in the
parked position, the engine does not start.
1. Checkpoints after starting the
engine
After starting the engine, but before starting operation,
check the following points:
1. The engine idle allows the engine lubricant to warm
up and penetrate every part of the engine.
NOTE :
• This idling is usually called "Warm-up".
2. Once the engine has warmed up, check:
• The engine-oil-pressure-warning-indicator has
gone out.
• The battery-charge-indicator goes out when
engine speed is increased.
• The color of the exhaust is normal and no
abnormal noises or vibrations are heard or felt.
• No fluid is leaking from pipes or hoses.

Conditions to stop the engine immediately
If any following conditions should occur, stop the
engine immediately.
• The engine rpm increases or decreases suddenly.
• Sudden abnormal noises are heard.
• Exhaust is black.
• Warning indicator for engine oil lights up during
operation.
IMPORTANT :
• In the preceding cases, check the machine and
ask your local KUBOTA dealer to service.
STARTING THE ENGINE UNDER
COLD CONDITIONS
Start the engine in the manner in this section in cold
weather.
1. Turn the starter switch to the [RUN] position (glow
position) and hold until the indicator lamp has gone
out.
2. Move the starter switch to the [START] position to
crank and start engine.
3. Release the starter switch after the engine has
started.
Starter switch will automatically return to the [RUN]
position.
IMPORTANT :
• Let the engine warm up after start-up for
approx. 10 minutes under no load conditions. If
the temperature of hydraulic fluid is too low, the
operations or the function of the pressure
sensors will be affected.
Do not operate the machine under full load
before the engine has warmed up enough.
STOPPING THE ENGINE
WARNING
To avoid personal injury or death:
• Do not keep the bucket or attachments in the
lifted
position,
because
accidentally touch the levers and cause serious
accidents.
• Place the machine on the flat ground.
IMPORTANT :
• Do not stop the engine before it cools
sufficiently, or the service life of the engine
parts may be shortened.
• If the engine overheats, do not stop it
immediately but cool it gradually by running it
at medium speed before stopping.
