23OPERATING THE ENGINE
COLD WEATHER STARTING
If the ambient temperature is below 0 (32 ) and the
engine is very cold, follow the procedure below after
taking the step 1 through 5 in the previous pages.
Heater indicator comes on when the key is turned to "ON"
position and engine coolant temperature is below 0
(32 ), and goes off automatically when preheat is
completed.
(If the engine fails to start after 10 seconds, turn off the
key for 30 seconds. Then repeat steps 6 through 8. To
protect the battery and the starter, make sure that the
starter is not continuously turned for more than 10
seconds.)
BBlock Heater (if equipped)
A block heater is available as an option from your dealer.
It will assist you in starting your tractor when the ambient
temperature is below -20 (-4 ).
STOPPING THE ENGINE
A If key does not stop the engine, consult your local
KUBOTA Dealer.
WARMING UP
[F8/R8 model]
To avoid personal injury or death:
A Be sure to set the parking brake during warm-
up.
A Be sure to set all shift levers to the "NEUTRAL"
positions and to place PTO switch in "OFF"
position during warm-up.
[F12/R12 model]
To avoid personal injury or death:
A Be sure to set the main gear shift lever to
"PARK" position and set the shuttle shift lever
to the "NEUTRAL" position and place the PTO
switch in the "OFF" position during warm-up.
For 5 minutes after engine start-up, allow 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, trouble such as seizure,
breakage or premature wear may develop.
BWarm-up and Transmission Oil at Low
Temperature Range
Hydraulic oil serves as transmission fluid. 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 trouble in the hydraulic system.
To prevent the above, observe the following instructions:
Warm up the engine at about 50 % of rated rpm according
to the table below:
6. Turn the key to "ON" position and hold
it until the heater indicator turns off.
(1) Heater indicator
7. Fully depress the clutch pedal.
8. Turn the key to the "START" position
and the engine should start.
1. After slowing the engine to idle, wait 3 to
5 minutes for turbo to slow down and
then turn the key to "OFF".
2. Remove the key.
