working temperature for oil is 50
℃
~80
℃
, if it is below 25
℃
, warm-up running should be done so
that the oil temperature can be raised to the required one for the operation.
While the machine is transferred out of factory, there has been long-term rustproof and anti-freeze
fluid in the radiator, which should be drained out totally to protect the machine from rust if the
machine is stopped for a long time.
