The correct amount of sag is 10~20mm (observed at the bottom of the unloading point during positive operation). During adjustment of the scraper chain, loosen the adjustment nut on the adjusting bolt. Note that the adjustment amount of the two sides shall be the same basically. After the sag amount of chain is 10~20mm, the adjustment nut is locked. If the adjustment amount is not enough, two sections of the chain can be removed.
