, the piston is not
moving freely within the liner and they must be
cleaned:
1. Remove the control section assembly, top cap
and thermostat.
2. Unthread the liner from the cap (it is glued
together; the o-rings must be removed and heat
should be applied to melt the glue and loosen
the liner).
3. Clean the piston and liner with any cleaner
suitable for brass and stainless steel (400-grit
sandpaper may be used to polish and hone the
piston and liner).
