Make sure that your line position is two screws, H screw and L screw. H, as the name implies, is the first letter of "Gao" in English words. L that goes without saying, low initials.

Step one, reduce the backswing to the minimum gear.

Second, squat down on the edge of the dental plate and hook the front dial with your hand to make it reach the largest plate. Check whether the height of the front dial and the toothed plate is about 1mm, and ensure that the front dial must be parallel to the toothed plate when viewed from top to bottom. So you finished the preparatory work first.

The third step is to loosen the fastening nut of the front dial and let it naturally receive the smallest plate. From top to bottom, the difference between your chain and the outer guide plate of the front dial is about 0.8 mm If the distance is far, loosen the L screw, which is the two screws I mentioned earlier. Until the distance is right.

Fourth, hang the thread, screw it to death, and air it to the biggest plate. If it can't get up, it proves that your H screw is too tight and needs to be loosened.

Fifth, when the chain reaches the largest disk surface, vigorously wave it again to dry and rotate the disk surface at the same time. The distance between the outer guide plate and the outermost end of the disc should be 0.6 mm. If the distance is too large, your chain will fall off the outside of the disc. At this time, press and blow dry the H screw until the distance I said is reached. Remember not to die too much, there is a moving distance of 0.2, otherwise it will be difficult to shift gears, and the distance will be much longer than before. After the above, if you don't get a ticket, then you are finished. Rest assured to ride.
