[. . . ] · Use the reinforced connecting pin only for connecting the narrow type of chain. · There are two different types of reinforced connecting pins available. If connecting pins other than reinforced connecting pins are used, or if a reinforced connecting pin or tool which is not suitable for the type of chain is used, sufficient connection force may not be obtained, which could cause the chain to break or fall off.

Reinforced Connecting Pin · If it is necessary to adjust the length of the chain due to a change in the number of sprocket teeth, make the cut at some other place than the place where the chain has been joined using a reinforced connecting pin or an end pin. [. . . ] · Use an outer casing which still has some length to spare even when the handlebars are turned all the way to both sides. Furthermore, check that the shifting lever does not touch the bicycle frame when the handlebars are turned all the way. · Grease the inner cable and the inside of the outer casing before use to ensure that they slide properly. · Operation of the levers related to gear shifting should be made only when the front chainwheel is turning.

Gear shifting operation
Both lever (A) and lever (B) always return to the initial position when they are released after shifting. When operating one of the levers, always be sure to turn the crank arm at the same time.
To shift from a small sprocket to a larger sprocket (Lever A)
To shift one step only, press lever (A) to the (1) position. To shift two steps at one time, press to the (2) position.

Installation of the sprockets
For each sprocket, the surface that has the group mark should face outward and be positioned so that the triangle (U) mark on each sprocket and the A part (where the groove width is wide) of the freewheel body are aligned.
