screw.
WARNING
EWB02492Suspension components become hot
during operation. Never touch the com-
pression damping force adjusting bolt
and screw, the rebound damping force
adjusting screw or the oil reservoir with
your bare hand or skin until suspension
components have cooled.

fore handling the shock absorber assem-
blies.
Do not tamper with or attempt to open
the cylinder assemblies.
 Do not subject the shock absorber as-
semblies to an open flame or other high

explode due to excessive gas pressure. 
Do not deform or damage the cylinders
in any way. Cylinder damage will result in
