Instructions for use
Thank you for purchasing your new SHOEI helmet. This manual contains valuable information to help you understand how to
operate and maintain your helmet. Please read this manual carefully before use and keep it for future reference. Your SHOEI
dealer can provide a replacement if this manual is lost.

Read This First
This product is a motorcycle helmet.
Do not use it for any purposes other than riding a
motorcycle. If you use the helmet for any other
purpose, it may not provide sufficient protection in
case of an accident.
No helmet can protect the wearer against
all foreseeable high speed and low speed
impacts.
For maximum head protection, the helmet must fit
properly and the retention system must be
securely fastened under the chin. The helmet
should allow sufficient peripheral vision when
secure on your head. If your helmet is too large, it
may slip or move on your head while riding. This
could cause your helmet to come off in an
accident or obstruct your vision while riding
resulting in personal injury or death. To learn to
properly wear and secure your helmet, see the
booklet “How to Use Your Helmet Properly” that
was packed with the helmet.
The contents of this manual are subject to change
without notice.

Service Tool

*PINLOCK® is a registered trademark of PINLOCK
SYSTEMS B.V.
Service tool is the tool to be used in following
cases.
・Removing sun visor
(Refer to „Removing the QSV-2 Sun visor“)
・Removing intercom base cover
(Refer to „When Installing the Intercom“)
・Adjusting PINLOCK® EVO lens
(Refer to the Drawing)
When adjusting PINLOCK®EVO
lens, read the instruction manual
that comes packed with it.
Service Tool
If you are using the PINLOCK®* EVO lens,
read the instruction manual that comes
packed with it.
PINLOCK®EVO lens
1. Daytime use only. Never use PINLOCK®
EVO lens at night. If the PINLOCK®EVO
lens is used with a clear shield/visor, its
light transmission ratio will be approximately
80%. This value does not meet the light
transmission standards in the U.S. (VESC-8,
85%), or Europe (ECE R22, 80%), so this
accessory is for „daytime use only“ in these
jurisdictions.
2. The PINLOCK®EVO lens is made of a material
that is easier to scratch than the outer
shield/visor. It should be treated with great care.
3. The PINLOCK®EVO lens may obstruct the
rider’s view in some riding positions.
4. Remove the protective film before using the
PINLOCK® EVO lens.
5. The PINLOCK®EVO lens demonstrates high
effectiveness in stopping fog by absorbing
moisture. However, if the helmet is used
continuously with the lower vent in the closed
position in low-temperature, high-humidity
conditions, the lens can become saturated with
water vapor causing streaks and fog to appear.
If streaks or fog appears, it may obstruct your
view and be very dangerous! In this case, open
the lower air intake and/or open the shield/visor
to circulate air within the helmet to remove the
streaks and fog from the helmet.
6. Purchase DKS301 for CNS-1 for replacement of
PINLOCK® EVO lens.

Important Notice about
Handling Interior Parts
1. When fastening or unfastening the snaps, you
should hold near the snaps and treat carefully.
Fasten the snaps firmily until they click in place.
2. You can clean the inner parts by hand washing
them or by washing them in a washing machine
after placing them in a laundry net. Please treat
them carefully when washing. Use lukewarm
water. Gently squeeze the parts with a dry towel
and dry them in the shade. To prevent damage
to the plastic areas of the interior parts, do not
wring them strongly and do not fold or bend the
plastic areas. Take special care if you are using
a washing machine. Do not dry the interior parts
with a clothes dryer, blow dryer, or any other
type of mechanical dryer, as heat can damage
the material. The impact absorbing liner
(polystyrene foam section) should be wet with a
soft cloth dipped in a solution of mild neutral
soap and water and then wiped. Allow time for
the impact absorbing liner to dry in the shade.
Do not dry the impact absorbing liner in the
sunlight or use any type of mechanical dryer, as
the impact absorbing liner is extremely sensitive
to heat. If the impact absorbing liner is exposed
to high heat of any kind, contact your dealer or
SHOEI directly for a safety evaluation. To
prevent damage, do not use any of the
following cleaning materials: hot water over
40°C; salt water; any acidic or alkali
detergent; benzine, thinner, gasoline, or
other organic solvents; glass cleaner; or any
cleaner containing organic solvents.

WARNING
1. Before use, check that the shield/visor hooks
and gears are fit firmly.
2. Be sure to always wear the center pad, cheek
pads, chinstrap covers when using the helmet.
3. When cleaning and caring for the helmet and
shield/visor, do not use any of the following
cleaning materials: hot water over 40℃; salt
water; any acidic or alkali detergent;
benzine, thinner, gasoline, or other organic
solvents; glass cleaner; or any cleaner
containing organic solvents. If any of these
cleaners are used, the helmet’s chemical nature
may be altered and safety may be hindered.
4. If insects become stuck to the helmet during
riding and are left in place, the helmet surface
may be corroded. They should be removed
promptly.
5. Be sure to use SHOEI genuine parts when
replacing the shield/visor, sun visor, or inner
parts.
E.Q.R.S. (Emergency Quick Release System) is a mechanism for
emergency personnel to remove the cheek pads.
To remove a cheek pad in an emergency, cut or undo a chinstrap
first. While holding the helmet firmly so that the rider’s head may
not move, take emergency tab (Drawing 1) and pull it to a direction
indicated in the drawing 2. (If the chin curtain is installed, it must be
removed before using the emergency tab.)
Pulling the emergency tab will release snaps and allow a cheek
pad to be pulled out through the bottom of the helmet while it is still
on the rider’s head. Repeat the same procedure to remove the
other side.
Be sure to hold the helmet firmly and pay full attention not to move
the rider’s head while removing the cheek pads.
