Front and Rear Shock Adjustment
WARNING
These shock absorber assemblies contain
highly pressurized nitrogen gas, read and
understand the following information
before handling the shock absorber
assemblies.
·
Do not tamper with or attempt to open
the cylinder assemblies.
·
Do not subject the shock absorber
assemblies 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.
·
Do not dispose of a damaged or worn out
shock absorber assembly yourself. Take
the shock absorber assembly to a HSUN
dealer for any service.
The spring preload, rebound damping and
compression damping forces of the front and
rear shock absorber assemblies can be
adjusted to suit the operating conditions.
NOTE:
Never turn an adjusting mechanism
beyond the minimum and maximum
settings.
Spring preload
1. Loosen the locknut.
2. Turn the spring preload adjusting nut in
direction
ⓐ
to increase the spring preload
and thereby harden the suspension, and in
direction
ⓑ
to decrease the spring preload
and
3. thereby soften the suspension.
·
A special wrench can be obtained at a
dealer to make this adjustment.
·
The spring preload setting is determined by
measuring distance A, shown in the illustration.
The shorter distance A is, the lower the spring
preload; the longer distance A is, the higher
the spring preload with each complete turn of
the adjusting nut.
