7. Do not fix and use the stroke adjusting unit 

at an intermediate position (MY3B/MY3M).

If the stroke adjusting unit is fixed at an intermediate position, 
an error may result depending on the collision energy. In that 
case, the use of the holder mounting bracket for adjustment is 
recommended. It is provided with the "-X416" or "-X417" 
made-to-order specification.
(Refer to “MY3B/MY3M Stroke Adjusting Unit Tightening Tor-
que for Fixing Bolts.”)
If the stroke adjusting unit is used at an intermediate position, 
the energy absorption capacity may be different. Refer to the 
maximum absorbed energy on page 6 and 21 and operate 
within the allowable absorption energy.

<Stroke adjustment of the adjustment bolt>

Loosen the lock nut for the adjustment bolt, adjust the stroke 
on the head cover side with a hexagon wrench, and secure 
with a lock nut.

<Stroke adjustment of the shock absorber: MY3B> 

Loosen the two unit fixing bolts on the shock absorber side 
and rotate the shock absorber for stroke adjustment. Tighten 
the unit fixing bolts equally to secure the shock absorber. Use 
caution not to overtighten the fixing bolts.
(Refer to “MY3B/MY3M Stroke Adjusting Unit Tightening Tor-
que for Fixing Bolts.”)

<Stroke adjustment of the shock absorber: MY3M> 

Loosen the fixing bolt for the shock absorber. Rotate the shock 
absorber and adjust it. Then, tighten the fixing bolt for the 
shock absorber and secure the shock absorber. Additionally, 
please be careful that the fixing bolt should not be tightened 
excessively.
(Refer to “MY3M Shock Absorber Tightening Torque for Fixing 
Bolts”.)
