dling the shock absorber assemblies.
●
Do not tamper with or attempt to open the
cylinder assemblies.
●
Do not subject the shock absorber assem-
blies to an open flame or other high heat
source. This may cause the unit to explode
due to excessive gas pressure.
●
Do not deform or damage the cylinders in
any way. Cylinder damage will result in poor
damping performance.
