(3) Check the motor oil pump, piping and valves for oil and water leakage.

(4) Check the liquid level of the oil tank.

(5) Check the flow of cooling water and mold cooling medium.

(6) Check whether there is abnormal noise at the motor oil pump, piping, valves, etc.

(7) Check the oil temperature. After the machine starts to run for several hours, the temperature of the hydraulic oil is generally within the range of 35 ℃ - 50 ℃.

(8) Check whether the system pressure is normal.

(9) Check whether the extruder assembly, splitter plate assembly and die head leak glue.

(10) Check whether the guide rod of the closing cutter assembly is worn, whether the clearance between the front cutter and the rear cutter is appropriate, and whether the cooling effect of the cutter is appropriate.

(11) Check the pneumatic system for problems.

(12) Check whether the central lubrication system is sufficient to lubricate each moving element.

(13) Check whether the safety gear door limit switch is in good condition and whether the trigger is normal. If not, the machine cannot be started.

(14) Check whether the on-off valve of the main oil circuit and the feedback input of the valve element are triggered normally. If they are abnormal, they cannot be started.
