User manual DAHON ALFINE CJ-8S20 TECHNICAL SERVICE INSTRUCTIONS

[. . . ] General Safety Information WARNING ­ To avoid serious injuries: When installing the hub to the frame, be sure to install the correct non-turn washers to the left and right sides, and securely tighten the hub nuts to the specified torques. If the non-turn washers are installed to one side only, or if the hub nuts are not tightened sufficiently, the non-turn washer may fall out, which could cause the hub axle to rotate and the cassette joint to turn. [. . . ] The CJ-8S20 cassette joint should only be used with sprockets from 16T to 23T. If using a chain tensioner, use the special CS-S500 18T or 20T sprocket with chain guard. Do not use any other types of sprockets, otherwise the chain may come off the sprockets. If the wheel becomes stiff and difficult to turn, you should lubricate it with grease. You should periodically wash the sprockets in a neutral detergent and then lubricate them again. In addition, cleaning the chain with neutral detergent and lubricating it can be a effective way of extending the useful life of the sprockets and the chain. If the chain keeps coming off the sprockets during use, replace the sprockets and the chain. Parts are not guaranteed against natural wear or deterioration resulting from normal use. For maximum performance we highly recommend Shimano lubricants and maintenance products. For any questions regarding methods of handling or adjustment, please contact the place of purchase.
