HANDLING THE REAR SHOCK ABSORBER
AND GAS CYLINDER
WARNINGWARNING
This rear shock absorber and gas cylin-
der contain highly compressed nitro-
gen gas. Before handling the rear shock
absorber or gas cylinder, read and make
sure you understand the following
information. The manufacturer cannot
be held responsible for property dam-
age or personal injury that may result
from improper handling of the rear
shock absorber and gas cylinder.
• Do not tamper or attempt to open the
rear shock absorber or gas cylinder.
• Do not subject the rear shock absorber
or gas cylinder to an open flame or
any other source of high heat. High
heat can cause an explosion due to
excessive gas pressure.
• Do not deform or damage the rear
shock absorber or gas cylinder in any
way. If the rear shock absorber, gas
cylinder or both are damaged, damp-
ing performance will suffer.
EB706111
DISPOSING OF A REAR SHOCK ABSORBER
AND GAS CYLINDER
Gas pressure must be released before dis-
posing of a rear shock absorber and gas cyl-
inder. To release the gas pressure, press on
the gas valve needle with a suitable tool as
shown, until all of the gas is released (the
hissing has stopped).
WARNINGWARNING
Wear eye protection to prevent eye
damage from released gas or metal
chips.
