Shimano SH-M310 Service Instructions

General Safety Information

SI-0070A-002

WARNING

Understand how the locking mechanism works before you ride.

Before riding, place one foot on the ground and practice engaging
and disengaging from the pedal a number of times until you get used
to it.

Practice riding on smooth ground first.

Before riding, adjust the retention force of the pedal to your liking.
(Refer to the adjustment instructions for the pedal set.)

Make sure that mud, dirt, and foreign objects don't build up in the
pedal-cleat interface area.

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.

These shoes are highly rigid and extremely lightweight and have been
designed to be used only as racing shoes. The surfaces of the soles
of these shoes are much slipperier than for conventional SPD shoes,
and so you should find a safe place where you can get used to
wearing the shoes before using them fully.
Use extreme caution when pedaling without fitting the cleats into the
pedals and when walking on wet and/ or smooth surfaces in order to
avoid a serious injury.

Select the right-sized shoes for your feet, and be sure to fasten the
loop & hook fasteners and/ or shoe laces when using.

Refer to the instructions supplied with your SPD pedals.

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.

Heat molding of the shoes must only be carried out by a properly­authorized Shimano footwear dealer. If the heat molding is carried out
incorrectly, burns or fire may result.

Check that there is no adhesive peeling off from around the soles
before using them.

If you have any questions regarding methods of installation,
adjustment, maintenance or operation, please contact a professional
bicycle 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.

– To avoid serious injuries:

NOTE:

These SPD shoes cannot be used with SPD/ SPD-R/SPD-SL pedals for
road riding.

Do not use washing machines or dryers to clean the shoes.

Allow your shoes to air-dry in a shaded area. Do not expose your shoes to
strong direct sunlight.
Do not apply heat with a dryer or similar appliance.

Do not leave the SPD shoes exposed to temperatures of 50°C or higher,
otherwise the shoes may become warped by heat.

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

SPD Custom-Fit Shoes

Type 1

These heat-molded custom-fit shoes can be used as they are without heat
molding, but any heat molding of the upper and inner sole must only be carried
out by a properly-authorized Shimano footwear dealer.
