When the oil temperature is the pressure shall be adjusted to
5. 40 ℃ 1.5 ~ 2. 0 psig (PRESS)
6. 45 ℃ 2.0 ~ 2. 5 psig (PRESS)
7. 50 ℃ 2.5 ~ 3.0 psig (PRESS)
During operation, if it is found that the pressure gauge always shows "0", it must check
whether there is air leakage in the tank or the pressure gauge damaged. And timely repair it.
