1. The sprocket ought to be installed on the shaft without skew and swing. In the same transmission assembly, the finish faces of both sprockets ought to be in the same plane. When the center range of the sprocket is usually less than 0.5 m, the deviation is 1 mm. When the guts distance of the sprocket can be 0.5 m or more, the deviation is 2 mm. Nevertheless, the side phenomenon of the friction sprocket tooth isn’t allowed, and if the two-wheel knitting can be too big, the chain is quickly damaged and the put on is accelerated. Care should be taken to check and change the offset when changing the sprocket.
2. The tightness of the lifting chain should be suitable, too limited to increase power usage, the bearing is simple to wear; too loose chain is easy to jump and unchain. The tightness of the chain can be: lifting or Motorcycle chain pressing from the center of the chain, the center distance of the two sprockets is approximately 2% – 3%.
3. The new lifting chain is definitely too long or stretched after use. It is difficult to regulate. The chain links can be removed, but they should be even. The links should go through the trunk of the chain, the locking tabs are inserted outside, and the starting of the locking tabs should be in the contrary direction of rotation.
4. Following the sprocket wears significantly, the brand new sprocket and the new chain ought to 
be replaced at the same time to make sure good meshing. It isn’t possible to replace a fresh chain or a fresh sprocket alone. Failure to take action may lead to poor engagement to accelerate the wear of the new or new sprocket. Following the sprocket tooth surface wears to a specific extent, it must be turned over in time (make reference to the sprocket used for the adjustable surface). To increase the use of time.
5. The outdated lifting chain can not be mixed with some new chains, or else it will easily cause influence in the transmission and break the chain.
6. Lift the chain to remember to fill up the lubricant in time. The lubricating essential oil must enter the mating clearance between the roller and the inner sleeve to boost working conditions to lessen wear.
