Control functions
1. Hose connector
TIP
If the shock absorber has no air pressure, the
gauge reading will be zero.
5. To increase the air pressure, operate the
pump a few times. The pressure should
increase slowly. If the pressure increases
rapidly, check to make sure that the
pump is properly connected and tight-
ened onto the air valve. To decrease the
air pressure, push the black bleed valve
button. NOTICE: Do not exceed 1034
kPa (10.3 kgf/cm², 150 psi).

Recommended air pressure:
TIP
To allow pressure to escape from the pump
and the shock absorber, push the button half-
way down and hold it. To allow only a small
amount of pressure to escape, push the but-
ton all the way down and quickly release it.

TIP
When removing the connector, the sound of
air escaping may be heard, but this is from the
pump hose, not the shock absorber.
7.
TIP
If the front shock absorber bottoms too easily
or rolls too much during cornering, increase
the air pressure by 34 kPa (0.3 kgf/cm², 5 psi).
If the shock absorber is too firm and you want
a more compliant ride, decrease the air pres-
sure by 34 kPa (0.3 kgf/cm², 5 psi).
FX10RTRS 345–1034 kPa (3.5–10.3
kgf/cm², 50–150 psi)
FX10RTRS 621 kPa (6.2 kgf/cm², 90
psi)
Remove the hose connector from the air
valve.
Install the air valve cap.
