1. Measure the degree of wear of the chain: - Insert a hook without text into the chain link and observe the end of the hook with text. - If it cannot be inserted at all, the chain is good. - If it is inserted to the value of 0.75, it means that the chain is worn but can still ride for a period of time. - If it is inserted into the value of 1.0, it means that the chain has been severely worn, and it is generally recommended to replace it immediately. 2. Chain maintenance hook: - Use the two hooks on the back of the measuring ruler to secure the chain. - It is more convenient for maintenance and removal of the chain. - Avoid getting oil on your hands and the chain bouncing. 3. Length measurement: - The laser laser scale on the lower part of the measuring ruler can measure the length of 1-10cm/0.39-3.94 inch. 4. Thread diameter measurement: - Insert the screw to be measured into the hole and push it in the direction of the small hole. - When you can not push it, you can know the thread diameter by observing the stop position number.
