In order to maintain proper performance, it is recommended that you lubricate the internal unit after riding

1,000 km from the start of use, then after about once every year (or once about every 2,000 km if the bicycle is

used very frequently). If the bicycle is used under harsh conditions, more frequent maintenance is required.

Also, for carrying out maintenance, the use of SHIMANO internal geared hub grease or a lubrication kit is

recommended. If SHIMANO grease or a SHIMANO lubrication kit is not used, problems such as a malfunction

in the shifting unit may occur.

If the wheel becomes stiff and difficult to turn, perform an inspection.

The gears should be periodically washed with a neutral detergent then lubricated. In addition, cleaning the

chain with a neutral detergent and lubricating it can be an effective way of extending the life of the gears

and chain.

If the chain keeps coming off the gears during use, replace the sprockets and chain.

If using a chain tensioner, use the special CS-S500 18T or 20T sprocket with chain guard. Do not use any other

types of sprocket, otherwise the chain may come off the sprockets.
