NOTICE:
Pull the rod of the shock absorber out gently to avoid spilling oil
or damaging the top cap and seal with the threads on the body
of the shock absorber. Wrap it in a cloth when removing the
shock absorber piston to soak up any oil that might run down the
sides.
Store the old oil in a container. Never re-use this old oil when
rebuilding a shock.
Remove the needle-type valve. Using compressed air, carefully
extract the floating piston from the body of the shock absorber.
Cover the opening of the shock absorber with a cloth to catch
the floating piston. Make sure there is enough space in the cloth
for the piston when it comes out.

WARNING
Always wear safety glasses and use a compressed air
gun approved by the O.H.S.A when working with
compressed air.
Clean the body of the shock absorber thoroughly using an
appropriate solvent. Dry it using compressed air and inspect it
carefully to detect any imperfections or marks indicating wear in
the bore. Replace the shock absorber in case of wear.
Put the shock absorber rod in a vise, then remove the piston
and the shims.
