1. Check whether there is a gas injection device in the grease adding pipeline. (Suggestion: Spray device should be installed near the mixer as far as possible).

2. Check whether the fuel injection nozzle is blocked. (Suggestion: add oil after heating in the use can prevent nozzle blocking).

3. Check whether the screen in the oil filter tank is damaged. Adjust the Angle of the nozzle to prevent oil from spraying onto the wall panels and blades at both ends of the mixer. Properly control the heating temperature of oil to prevent oil from being sprayed into the material. In the process, add the finished product inspection screen after mixing, break up the mixed oil group and remove it.
