General Safety Information
WARNING
• Check that the wheels are fastened securely before riding the bicycle. If the wheels are
loose in any way, they may come off the bicycle and serious injury may result.
• Obtain and read the service instructions carefully prior to installing the parts. Loose,
worn or damaged parts may cause the bicycle to fall over and serious injury may occur as
a result. We strongly recommend only using genuine Shimano replacement parts.
• Read these Technical Service Instructions carefully, and keep them in a safe place for
later reference.
• If the CS-HG61 cassette sprocket (12-36T) is installed onto a mountain bike, a large gear
ratio between front and rear rings can be obtained so that the mountain bike can ride up
steep slopes, but this will also place a heavy load on the rear hub. Shimano provides a
rear hub which can provide enough strength and durability if using this cassette sprocket
in combination with a front chainwheel set (22-32-44T).
If using the cassette sprocket in combination with any hub other than the FH-M629/FH-
M529, the hub may become damaged. Check the Shimano website for the most up-to-
date information regarding compatible Shimano hubs. (http://www.shimano.com)
Note
• The FH-M629/FH-M529 is compatible with the CS-HG61 (12-36T).
• Use the CS-HG61 in combination with 9-speed chains (CN-7701 / HG93 / HG73 / HG53).
• If the wheel becomes stiff and difficult to turn, you should lubricate it with grease.
• Do not apply any oil to the inside of the hub, otherwise the grease will come out.
• 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.
