Cleaning and Servicing Inlet or Check Valves
If either the inlet or check valve seems plugged or
damaged:
Remove the actuating lever. Remove and disassemble
the plugged valve. Clean all parts and inspect for wear
or damage, replacing parts as necessary. Lubricate
parts with a light grease and reassemble the valve. Align
the hole in the ball
with the hole through the body
Refer to the Parts Drawing.
Unscrew the swivel
from the check valve and screw
the check valve seat (15) out of the mixer head
Disassemble the valve and clean all parts. Also clean the
passageway in the head. Check the valve seat
for
nicks and replace parts as necessary. Replace the
gasket (26) reassemble and screw into the mixer. Refer
to mixing assembly.
Tap on the mixing chamber
with a piece of wood
or a plastic hammer to break it loose, then pry it off.
Knock out the mixing shaft, if possible, and place parts
in a pail of compatible solvent. If the mixing shaft
will not come out, and there is no solvent available that
will dissolve the material without damaging the parts,
install a complete new mixing assembly. Refer to mixing
assembly .
Completely disassemble the mixer and clean it
thoroughly. Reassemble, using new packings, glands
and any other parts, as necessary. Be sure that no
hardened material remains on any part of the mixer.
Be sure to check and then observe the mixed
pot
to prevent
from harden-
ing in the mixer and resulting in costly damage.
Install the swivel and actuating lever.
If Material Hardens in the Mixing Chamber
Shut off air to the solvent and material supply pumps.
Close the mixer inlet valves and
loosen the
material inlet hoses to relieve pressure. Then remove
the mixing assembly retaining nut and disconnect the
dispensing hose.
