Instruction
1. Clean the switch, rollers of the natyazhitel and the chain from dirt. Grease the last. Pay attention that screws on back switches can be located depending on model, differently. Restrictive screws most often are sideways, but not behind.
2. Establish the chain on the smallest asterisks behind and in front. On the switch find adjusting screw L and screw H. Weaken the cable of the back switch. For this purpose clockwise rotate against the stop the drum of adjustment of the tension. Make the same actions with the drum on the coin.
3. Remove the cable. By means of the internal hexagon weaken the attachment screw of the cable and take it from the binding. You can not take out it from the switch, however check in what it the state. Replace the untwined or worn-out cable, and dirty – clean and grease. Put in order, it will provide gear shifting clearness.
4. Establish big passes. For this purpose get up behind the bicycle and level the smallest asterisk and rollers of the natyazhitel, turning screw H. Track that rollers appeared on one straight line with the asterisk.
5. If rollers of the natyazhitel remain shifted to the right, the chain will pass to big asterisks hardly. In this case twist screw H clockwise. If rollers are shifted to the left, the chain won't be able freely to pass to smaller asterisks. Here it is necessary to twist the same screw against the course of the hour hand. At correctly adjusted big passes the chain will silently work at the smallest asterisk also without jumps aside.
6. Establish the cable. Fill it under the attachment screw. One hand strongly pull it, and another at this moment tighten the attachment screw. If the flute for the cable is provided, then be convinced that the cable got to it, but didn't lay down nearby. Tightening the screw, show care and don't strip the thread.
7. Establish small passes. For this purpose turn out screw L almost up to the end so that it didn't limit movement of the switch. Begin to rotate pedals and at the same time transfer the coin to the first pass. Do it carefully as before adjustment the chain can get to needles, having slipped more to the left of the greatest asterisk.
8. Adjust small passes. Having risen behind the bicycle, turn screw L and level the biggest asterisk and rollers of the natyazhitel until they appear on one straight line. Usually the screw needs to be tightened prior to its hard spin.
9. Adjust the natyazhitel of the chain. Having put it on the smallest lobby and the greatest back asterisks, twist pedals back. If the top roller of the natyazhitel concerns asterisk teeths, twist the screw, having achieved discharge of the roller from teeths on 5 mm. Then transfer the chain to the smallest asterisk and check the chain tension there.
