3. Check whether the hole class (mold) is used correctly during production and whether it is fixed?


4. Check whether the cutter is tight and whether it can cut in place in a full cycle? After adjusting the angle of the cutter, turn it on and see if the sound is the same as usual?


5. Is the steam supply cylinder of the extruder maintained above 0.6Mpa, and is the "tape measure" valve open for drainage?


6. Before starting the machine, open the oil rod (bearing oil tank) (gear oil tank) and start to see if the oil is circulating?
