distributor or any of the SHIMANO ofﬁces to obtain a hardcopy of the User's Manual.

•Please observe the appropriate rules and regulations of the country, state or region in

which you conduct your business as a dealer.

For safety, be sure to read this dealer’s manual thoroughly before use, and

follow it for correct use.

The following instructions must be observed at all times in order to prevent personal injury

TO ENSURE SAFETY

WARNING

• Be sure to follow the instructions provided in the owner's manual when installing the

product.

It is recommended to use SHIMANO genuine parts only. If parts such as bolts and nuts

become loose or damaged, the bicycle may suddenly fall over, which may cause serious

injury.

In addition, if adjustments are not carried out correctly, problems may occur, and the

bicycle may suddenly fall over, which may cause serious injury.

•Be sure to wear safety glasses or goggles to protect your eyes while performing

maintenance tasks such as replacing parts.

•After reading the dealer's manual thoroughly, keep it in a safe place for later reference.

Be sure to also inform users of the following:

•Be careful not to let the hemming of your clothes get caught in the chain while riding.

Otherwise, you may fall off the bicycle.

NOTICE

Be sure to also inform users of the following:

•If gear shifting operations cannot be carried out smoothly, clean the derailleur and

lubricate all moving parts.

•When the chain is in any of the positions shown in the ﬁgure, the chain may come into

contact with the front chainring or front derailleur and generate noise. If noise is a

problem, shift the rear sprocket to the next largest gear or the one after.

TO ENSURE SAFETY

•Products are not guaranteed against natural wear and deterioration from normal use

and aging.

•For maximum performance we highly recommend SHIMANO lubricants and maintenance

products.

For Installation to the Bicycle, and Maintenance:

•Use an OT-SP sealed cable and cable guide for smooth operation.

•Grease the inner cable and the sliding portions of the outer casing before use to ensure

that they slide properly.

Do not let dust adhere to the inner cable. If the grease on the inner cable is wiped off,

the application of SIS SP41 grease (Y04180000) is recommended.

•If using a full outer model, the end of the

outer casing with the outer cap (resin type)

should be at the derailleur side.

•If using it in a cold region, use a sealed

outer cap (resin type) to prevent freezing.

•If looseness in the links is so great that gear shifting adjustments cannot be made,

replace the derailleur.

The actual product may differ from the ﬁgure because this manual is intended

mainly to explain the procedures for using the product.
