6.2 Adjustments

6.2.1 Adjustment of compensator air pressure

By introducing pressurised air through the valve, it is
possible to modify the damping of the forces generated
during compression at the end of travel.
By increasing the air pressure, the hydraulic damping is
increased during the fi nal compression phase, vice versa by
reducing the pressure the hydraulic damping is reduced.
• Remove the protection cap.
• Tighten the pump adapter on the valve and infl ate till
reaching the pressure you wish.
• Refi t the protection cap.

ARNING
To keep the pressure inside the rear shock only use the
special MARZOCCHI pump with pressure gauge, which
can be purchased at any Marzocchi authorised centre.
The use of any other type of pump can jeopardise the
infl ating operation and cause malfunction or damage
to the rear shock with consequent accidents, personal
injury and even death.

6.2.2 Spring preload

Spring preload is used to set the SAG or rate of compression
when you sit on the bike and when it is being ridden.
P
• The preloading of the spring can be adjusted by turning
ring nut (P) (clockwise increases and anticlockwise
decreases the preloading).
W !
ARNING
Don't preload the spring more than 5mm (0.2") for any
reason. Preloading over the value can break the spring
preload nut or the spring clip. The spring must be
preloaded at least 1mm, if this is not done the spring
preload nut can unscrew with serious consequences to
the cyclist. If the shock absorber is still too soft after
preloading the spring to a maximum 5mm (0.2"), you will
have to change the spring with a fi rmer one. The same is
to be said for a spring with only 1mm of preload being
too fi rm, it will need to be changed to a softer one.
W !
ARNING
Replacing the spring involves removing the rear shock
from the frame, therefore this must be done by a
specialized technician.
