WARMING-UP OPERATION FOR STEERING HYDRAULIC CIRCUIT IN COLD
WEATHER
3
WARNING
When the oil temperature is low, if the AJSS lever is oper-
ated or any operation to stop in a certain position is car-
ried out, there may be a time lag before the machine turns
and stops.
In this case, to ensure safety, use the frame lock lever and
carry out the warming-up operation in a wide space.
When doing this, do not relieve the pressure in the hydrau-
lic circuit continuously for more than 5 seconds.
When the temperature is low, do not start the operation of the machine immediately after starting the engine.
Warming up steering hydraulic circuit
Slowly operate the AJSS lever to the left and right to warm up the oil in the steering valve.
(Repeat this operation for about 10 minutes to warm up the oil.)
NOTICE
Operate the AJSS lever a little and stop in that position. Then confirm that the machine is being steered by
an angle equivalent to the amount that the AJSS lever is operated.
RECOMMENDED OIL
Select the oil from the table below according to the ambient temperature.
