CLEAN- 1.0.3 HYDRO BLOCK / HYDRO CHAMBER
Referring to Figure 32 (page 71), is the machine equipped with the Old Style Hydro Block or New Style
Hydro Chamber?
Old Style Hydro Block: See procedure number
New Style Hydro Chamber: See procedure number CLEAN- 2.0.0 (page 72).
CLEAN- 1.0.4 CHECK DEAERATION RESTRICTOR (OLD STYLE HYDROBLOCK)
a) Turn the machine off and clamp the vent tubing.
b) Referring to Figure 32
c) Check or replace BOTH restrictor o-rings (P/N 579070). These rings should be replaced during Annual
Preventative Maintenance. Bad o-rings will cause this problem!
d) Reinstall the restrictor until it is snug. NEVER use an electric screwdriver or over tighten as the threads
may strip. If the restrictor does not tighten snug it may be stripped and this requires replacing the
hydro block.
IMPORTANT!
e) Unclamp the vent tubing.
f) See procedure number CLEAN- 2.0.0 (page 72).
