Stopping The Engine; Warming Up; Warm-Up And Transmission Oil At Low Temperature Range - Kubota M5N-091 Operator's Manual

32 OPERATING THE ENGINE

STOPPING THE ENGINE

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.
IMPORTANT [M5N-091, M5N-111]
A When the engine is stopped-shutdown, DEF/AdBlue®
flow is reversed in the DEF/AdBlue® lines and related
piping and returned back into the DEF/AdBlue® tank
after cooling the DEF/AdBlue® injector.
The SCR system continues working several minutes
after engine shutdown to complete this purge process.
A Do not turn the machine main battery power off to the
engine until the DEF/AdBlue® return cycle purge
process is completed. Turning off the main battery
power to the engine and aftertreatment system prior to
completion may damage the system or cause it to
malfunction.
A If key does not stop the engine, consult your local
KUBOTA Dealer.

WARMING UP

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.
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:
Ambient temperature
Higher than 0 (32
0 to -10 (32 to 14
-10 to -20 (14 to -4
Below -20 (-4 )
A Do not operate the tractor under full load condition until
it is sufficiently warmed up.
Warm-up time requirement
