3. Depressurize the main chamber first; then depres-
surize the EVOL chamber next.
NOTE: When depressurizing the chambers, a
"hissing" should be noticed as air is released.
Also, the shock normally contracts slightly due to
the internal negative spring.
4. Using a strap wrench at the very end of the sleeve,
loosen, but do not remove, the air sleeve.
5. Remove the shock from the vise, invert it, and
clamp it in the vise by the reservoir eyelet.
6. Unthread the air sleeve from the EVOL chamber
by hand and slide it down the body.
NOTE: Look for oil in the air chamber which may
be at the top of the bearing head assembly. There
should be a small amount of assembly lube (blue)
present, but any indication of shock oil (red) indi-
cates worn shaft seals.

7. Using a 5/64-in. hex key, remove the button screw
from the nitrogen pellet valve.
8. Using a Fox nitrogen safety needle, press it
through the rubber pellet to depressurize the nitro-
gen charge. When the shock is fully discharged,
pull the needle away in a straight, smooth motion.
NOTE: At this point, inspect the nitrogen valve
for signs of wear such as holes on the face of the
pellet. Replace if necessary.
