1. Before starting the machine, generally check the following items:
   1) Whether the vibrating screen bolts are tightened, whether there is any jamming, and whether there are obstacles around the vibrating screen.
   2) Is the screen surface damaged?
   3) Whether the water spray device is unblocked and whether there is fine grain impurities in the feed water.
   2. When turning on the power, first turn on the power, then rotate the start switch to the running position.
   3. When working, always check whether the screen vibrating cap is tightly pressed against the screen, and whether the vibration at each vibrating cap is significantly different.
   4. shaker if abnormal noise, especially those with metal crash, should be immediately shut down, power-off, the interior of the electromagnetic exciter air gap adjustment Electrical notification size, generally the smaller the better, as far as possible using a small current, small amplitude.
   5. The angle of the screen surface should be adjusted in time according to the nature of the screen material and the screening effect.
   6. According to the size of the feed, the current of each vibrator should be adjusted in time to change the amplitude.
   7. The screen should be strictly protected to prevent trampling. Non beat screen surface with a wooden stick, and other hard objects iron. When the sieve surface is clogged, use a soft brush to clean or rinse with water.
   8. If the screen surface is damaged, it should be replaced in time. The screen should be tiled and properly tensioned to avoid twisting and wrinkling on the screen surface. When the sealing strip is installed, the lower plane should be pressed against the screen. Do not open or enclose foreign objects, tighten the nut and put on the bolt protective cap.
   9. When the vibrating screen stops, the feeding should be stopped first, and all the materials on the sieve surface should be removed. Continue to vibrate and clean the screen surface before stopping.
   10. Check the bolts connecting the vibrating rod and the vibration shaft after stopping to prevent loosening.
