Warming Up; Warm-Up And Transmission Oil In The Low Temperature Range - Kubota T1880 Operator's Manual

14 OPERATING THE ENGINE

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 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 in the 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 machine under full load condition
until it is sufficiently warmed up.
Warm-up time requirement
