If the temperature of the hydraulic oil is not as specified, run the engine at full throttle, hold the blade control lever in the RAISE position and slowly close the pressure valve on the Flowmeter until the pressure gauge indicates 103 bar (1500 psi). Continue to run the engine until the temperature of the oil is as specified.
