General Safety Information

WARNING

– To avoid serious injuries:

SPD-SL pedals are designed so that you release them

only when you intend to release. They are not designed

to release automatically at times such as when falling

off the bicycle. This is a safety measure to prevent you

from losing balance and falling off the bicycle as a

result of your feet becoming accidentally released from

the pedals.

Use only SPD-SL shoes with this product. Other types

of shoes may not release from the pedals, or may

release unexpectedly.

Use only Shimano cleats (SM-SH10 / SM-SH11) and

tighten the mounting bolts securely to the shoes.

Before attempting to ride with these pedals and shoes,

make sure you understand the operation of the

engagement / release mechanism for the pedals and

cleats (shoes).

Before you attempt to ride with these pedals and shoes,

apply the brakes, then place one foot on the ground and

practice engaging and releasing each shoe from its

pedal until you can do so naturally and with minimal

effort.

Ride on level ground first until you become adept at

engaging and releasing your shoes from the pedals.

Before riding, adjust the spring tension of the pedals to

your liking.

When riding at low speed or when there is a possibility

that you might need to stop riding, (for example, when

doing a U-turn, nearing an intersection, riding uphill or

turning a blind curve), release your shoes from the

pedal beforehand so that you can quickly put your feet

onto the ground at any time.

Use a lighter spring tension for attaching the pedal

cleats when riding in adverse conditions.

Keep cleats and bindings clear of dirt and debris to

ensure engagement and release.

Remember to check the cleats periodically for wear.

When the cleats are worn, replace them. Always check

the spring tension after replacing the pedal cleats and

before riding. If you do not maintain both your shoes

and cleats in good condition, release and engagement

to the pedals could become unpredictable or difficult,

which could result in severe injury.

Be sure to attach reflectors to the bicycle when riding at

night. Do not continue riding the bicycle if the reflectors

are dirty or damaged, otherwise it becomes more

difficult for oncoming vehicles to see you.

Obtain and read the service instructions carefully prior

to installing the parts. Loose, worn, or damaged parts

may cause serious injury to the rider.

We strongly recommend only using genuine Shimano

replacement parts.

If you have any questions concerning your pedals,

contact a professional dealer.

Read these Technical Service Instructions carefully, and

keep them in a safe place for later reference.

BE SURE TO READ AND FOLLOW THE ABOVE

WARNINGS CAREFULLY.

If the warnings are not followed, your shoes may

not come out of the pedals when you intend or they

may come out unexpectedly or accidentally, and

severe injury may result.

NOTE:

Check that there is no looseness in any joints or

connections before riding the bicycle. (BB-FC, FC-PD)

In addition, if pedaling performance does not feel normal,

check this once more.

Parts are not guaranteed against natural wear or

deterioration resulting from normal use.

For maximum performance we highly recommend

Shimano lubricants and maintenance products.

Engaging the cleats with the pedals

Press the cleats into the pedals with a forward and downward motion.

Releasing the cleats from the pedals

Release the cleats from the pedals by twisting your heels outward.

Note:

Place one foot on the ground, apply the brakes, and practice

engaging and releasing the cleat from the pedal several times to

determine the spring tension you prefer.

Attaching the cleats

Set the cleat on the bottom of each shoe as shown in the

illustration, and then provisionally tighten the cleat mounting bolts.

Refer to the service instructions provided with your shoes for

further details.

Note:

When installing the cleats, use the cleat mounting bolts and

the cleat washers that are provided with the cleats. If you use

any other cleat mounting bolts, it may damage the cleats and

cause problems with correct installation.

The spring force is adjusted by means of adjustment bolts at the

rear of the pedals. Face the cleats in the direction of release when

making this adjustment.

Equalize the spring tensions for both pedals by referring to the

tension indicators and by counting the number of turns of the

adjustment bolts.

The spring tensions can be adjusted in four steps for each turn of

the adjustment bolts, and each adjustment bolt can be turned up to

Use an 8 mm Allen key (for PD-7810 pedals) or a 15 mm spanner

(for PD-6620 / PD-5610 pedals) to mount the pedals on the crank

arms.

The right pedal has a right-hand thread; the left pedal has a left-

hand thread.
