Unit must be unplugged
before servicing
Inspect the leaf valves for damage or wear.
NOTE: There is one intentionally “bent”
leaf valve per set. If leaf valves need to be
replaced, a complete leaf valve plate can be
ordered. The screws holding the leaf valves
are susceptible to breaking which makes in-
dividual leaf valve replacement very dicult.
Remove the cylinder o-ring(s) from the bot-
tom of valve plate(s) and install new o-rings.
