IMPORTANT NOTICE

• This dealer's manual is intended primarily for use by professional bicycle mechanics.

Users who are not professionally trained for bicycle assembly should not attempt to

contained in this dealer's manual.

•All dealer's manuals and instruction manuals can be viewed on-line on our website

(http://si.shimano.com).

•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

and physical damage to equipment and surroundings. The instructions are classiﬁed

according to the degree of danger or damage which may occur if the product is used

TO ENSURE SAFETY

WARNING

• Be sure to follow the instructions provided in the manuals 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:

• Downhill bicycle riding and freeriding are inherently dangerous activities. There is a risk

of being involved in an accident that can result in a serious injury or even death. It is

strongly recommended that riders wear protective head and body gear and perform

thorough safety checks of their bicycles before riding. Please remember that you are

riding at your own risk and that you have to consider your experience and your skills

very carefully.

• Check that there are no cracks in the crank arms before riding the bicycle. If there are

any cracks, the crank arm may break and you may fall off the bicycle.

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

Otherwise you may fall off the bicycle.

CAUTION

For installation to the bicycle, and maintenance:

•There is the danger of injury from the tips of the teeth on the chainrings.

NOTE

For installation to the bicycle, and maintenance:

•Use a neutral detergent to clean the crank arm and the bottom bracket. Using alkaline or

acidic detergents may cause discoloration.

TO ENSURE SAFETY

•If pedaling performance does not feel normal, check the bicycle once more.

•Do not wash the bottom bracket with high-pressure jets of water. Water may enter the

bearing section and cause noise or adhesion.

•The gears should be periodically washed with a neutral detergent. In addition, cleaning

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

the life of the gears and the chain.

•The cuffs of your clothing may get dirty from the chain while riding.

•This product is not warranted against damage resulting from improper use, such as

jumping while riding or if the bicycle falls over, except if such malfunctions are caused by

manufacturing methods.

•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.

The actual product may differ from the illustration because this manual is

intended mainly to explain the procedures for using the product.

About compatibility

INSTALLATION/REMOVAL

For bicycles with rear suspension, make sure in advance that there is no weight applied to the

rear suspension.

NOTE

•When installing parts on a carbon frame, conﬁrm the recommended tightening torque

with the carbon frame or part manufacturer in order to prevent damage to the carbon

material due to overtightening or inadequate securing of the components due to

insufﬁcient tightening torque.

3. Adjust the height of the guide.

(1) Loosen the guide mounting bolt half a turn.

* When the guide mounting bolt is loosened, the guide can be moved up and down.

Be careful not to loosen the bolt excessively, as this will increase the looseness of the

guide and make position alignment difﬁcult to perform.

(2) Adjust the vertical position of the guide.

* Set the guide so that the bottom edge of the chain and the bottom edge of the

guide overlap when viewed from the right crank side.

* Do not tighten the guide mounting bolt at this time.
