3）As shown in Figure 3 above, hold the damper with the left hand and lift it slowly. Adjust the position of
the screw hole of the cylindrical movable pin with the right hand, and then align the mouth of the adjusting
screw with the screw hole of the cylindrical movable pin. Slightly lift the left hand to make the mouth of the
adjusting screw completely align with the screw hole. Then screw the adjusting screw with the right hand
clockwise, and the screw thread goes more than 5mm out of the cylindrical movable pin.
Note: In this process, the left hand shall always lift the damper upward with a little force to prevent
the damper from falling and hurting the hand!

damper slide from the slot C on the iron stand to the slot D, so that it can be adjusted during riding training.
Note: during operation, hold the damper with one hand gently, and hold the cylindrical movable pin
with the other hand to slide it from slot C to slot D. Pay attention to prevent hand injury during
sliding!
