first,we need Start the electric motor and check the rotating direction; press the pumping button, the piston push of concrete cylinder should match the S pipe reversing action correctly, the push frequency should conform to requirements, and the set value of main oil pressure should meet the requirements.

second,press the piston reversing button, test reversing pumping control, and the piston reverse direction and restitution should be flexible and reliable.

third,check the concrete pump electric indicator light and hydraulic pressure gauge, and the indication should be true and there should be no fault; after 30 minutes of free load running, every rotating part should have no strange sound and violent crack phenomenon; there is no oil leakage for hydraulic system, and the oil level and oil temperature in the oil tank should be normal; there is no apparent decline for water level in water tank.
