Shimano CAPREO DRIVE SYSTEM - TECHNICAL サービス手順

General Safety Information

WARNING

• Use neutral detergent to clean the chain. Do not use alkali-based or acid based

detergent such as rust cleaners as it may result in damage and/or failure of the chain.

• Use the reinforced connecting pin only for connecting the narrow type of chain.

• There are two different types of reinforced connecting pin available. Be sure to check

the table below before selecting which pin to use. 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.

• 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. The chain will be

damaged if it is cut at a place where it has

been joined with a reinforced connecting

pin or an end pin.

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

otherwise you may fall off the bicycle.

• Check that the tension of the chain is correct and that the chain is not damaged. If

the tension is too weak or the chain is damaged, the chain should be replaced. If this

is not done, the chain may break and you may fall off the bicycle.

• 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.

• 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, read and carefully service instructions when installing parts. A loose, worn,

or damaged parts may cause injury to the rider.

We strongly recommend that only genuine Shimano replacement parts be used.

• Read these Technical Service Instructions carefully, and keep them in a safe place for

later reference.

CAUTION

• The components of the F700 Capreo drive system are designed for use with

collapsible-type bicycles with small wheel diameters that are intended for riding on

sealed surfaces.

If they are used with bicycles that are to be ridden on unsealed surfaces or bicycles

with wheels that are larger than 20 inches, the components may become bent or

damaged.

Note

• In addition, if pedaling performance does not feel normal, check this once more.

• Check that there is no looseness in any joints or connections before riding the

bicycle. (BB-FC, FC-PD)

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

• If you feel any looseness in the bottom bracket axle, the bottom bracket should be

replaced.

• If gear shifting operations do not feel smooth, wash the derailleur and lubricate all

moving parts.

• If the amount of looseness in the links is so great that adjustment is not possible, you

should replace the derailleur.

• You should periodically clean the derailleur and lubricate all moving parts

(mechanism and pulleys).

• If gear shifting adjustment cannot be carried out, check the degree of parallelism at

the rear end of the bicycle. Also check if the cable is lubricated and if the outer casing

is too long or too short.

• If you hear abnormal noise as a result of looseness in a pulley, you should replace

the pulley.

• If the wheel becomes stiff and difficult to turn, you should lubricate it with grease.

• Do not apply any grease to the inside of the hub, otherwise the grease will come out

again.

• 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.

• 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.

• Parts are not guaranteed against natural wear or deterioration resulting from normal

use.

• For maximum performance we highly recommend Shimano lubricants and

maintenance products.

• For any questions regarding methods of installation, adjustment, maintenance or

operation, please contact a professional bicycle dealer.

Gear shifting operation

Both lever and button return to the initial lever or button position when they

are released after shifting. When operating lever or button, always be sure

to turn the crank arm at the same time.

To shift from a smaller sprocket to a larger sprocket

close to the sprocket as possible but not so close that it

touches. Next, set the chain to the smallest sprocket and

repeat the above to make sure that the pulley does not

touch the sprocket.
