There are many reasons for the case where the handle gourd can rise or fall, which is caused by incorrect operations and improper maintenance. There are several reasons for the pouring gourd to rise or not: the brake pads are not separated: This is one of the main reasons for the pour gourd only. According to the inertia, you can pull down the zipper down and pull it a few times. When you feel the chain rolled down, that is, the brake pads are successfully separated. Knock in the counterclockwise direction to separate the brake pads and the spiny wheel set. Card chain: The operator will have a break -off or card chain when driving the chain too much, so that the hand -pulling gourd can no longer continue to work. At this time, just restore the chain in place, and then pay attention not to the hand pulling power too much. Miscellaneous stuck: Most of the hand -stretched gourds are operating outside the open -air outdoors, and it is easy to have debris to enter the interior. This will cause the resistance of gears and bearing to excessive resistance, which will cause problems such as lifting and not flexibility. Use immediately to check whether there are debris inside, especially gears, bearing and other parts to clean up the debris. Damage to spiny paws: If the dilated paw is damaged, the spiny wheel will be killed, causing the hand to stract the gourd to be reduced. At this time, you only need to replace the thorns. The screw is too tight: If the internal screw is twisted too tightly, the five -foot long shaft cannot rotate flexibly, which will cause this problem. Just check the screws a little after checking. Excessive friction: The friction of the hand -stracting parts of the hand can cause the bearing operation when the operation is not flexible, and the long -term long -term will cause problems such as rising or falling. If it is caused by too much friction, you can use butter to increase lubrication. In daily use, especially the hot season, you should pay more attention to the problems caused by too much friction. There are six reasons for the above six reasons. In the case of this situation, as long as you encounter this situation, you can check them one by one according to the above six cases.
