[. . . ] If the wheels are loose in any way, they may come off the bicycle and serious injury may result. Before use, check the wheels to make sure that there are no bent or loose spokes, dents, scratches or cracks on the rim surface. Do not use the wheel if any of these problems are found. [. . . ] After inserting the spoke into the hole in the hub flange, tighten the nut. When installing, use the spoke stopper to secure the spoke so that it does not turn, and then insert a screwdriver or similar tool into the groove in the nut to screw in the nut. Turn the plug clockwise to screw it into the screw hole in the rim. At this time, use the spoke stopper to stop the spoke from turning. Note: If the washer is not installed, it will not be possible to adjust the spoke tension, so be sure to include the washer. Tighten the nut as far as the edges of the thread.

Rim tape may make it difficult to remove and install the tire, and the tire or tube may become damaged or the tires may suddenly puncture and come off, and severe injury may result. Burn-in period Disc brakes have a burn-in period, and the braking force will gradually increase as the burnin period progresses. Make sure that you are aware of any such increases in braking force when using the brakes during the burn-in period. The same thing will happen when the brake pads or rotor are replaced. Maintenance These units can be disassembled as shown in the illustrations. Grease should be applied to each part at periodic intervals.
