Doosan DX210 and DX225LCB Manual Instruction Extract:

START-UP PROCEDURES
1. Before operating machine, make sure that oil passages and hydraulic oil are clean.
2. Hydraulic oil of which annealing point is 82 – 113C (180 – 235F) should be used in the hydraulic system.
3. Relief valve pressure should not be raised above specified pressure setting.
4. The difference between main relief valve setting pressure and overload relief valve setting pressure should not be over 2.0 MPa [20.39 kg/cm2 (290 psi)].
5. Before operating machine, the hydraulic system should be fully warmed up. If machine is operated with cold hydraulic oil and valve, be careful of the following, to prevent spool sticking due to heat shock.

NOTE: Do not operate main relief valve or overload relief valve suddenly and continuously. Cycle oil through all actuators and warmed up cold hydraulic oil in the lines and components uniformly.
NOTE: Slight or compound work should not be suddenly operated at cold weather because heat is developed partly at all the orifices.
