the following information before
handling the shock absorber. The
manufacturer cannot be held re-
sponsible for property damage or
personal injury that may result from
improper handling.
● Do not tamper with or attempt to
open the gas cylinder.
● Do not subject the shock ab-
sorber to an open flame or other
high heat sources, otherwise it
may explode due to excessive
gas pressure.
● Do not deform or damage the
gas cylinder in any way, as this
will result in poor damping per-
formance.
● Always have a Yamaha dealer
service the shock absorber.
