(3) Dismantle gear speed reducer box, and bearing cover, to check quality of lubrication oil and metal powder content in the oil, PLS clean lubricated part, change or filter lubrication oil if necessary; 

(4) Check wear-out status of transmission gear and rolling bearing, do surveying for seriously worn-out bearing to prepare for stand-by parts production or purchase plan; 

(5) Check and calibrate heating temperature of barrel and die & temperature displayed on control box instrument by mercurial thermometer. 

(6) Adjust and test each safety alarm device to ensure its working accuracy and reliability. 

(7) Test and check if all the water and gas pipelines are going through, clean or repair leaked or blocked places;
