PART 4 MAINTENANCE
ANNUAL INSPECTION:
1. Inspect cutting mechanism for wear. The blade
edges should be free of nicks and gouges. If
impeller blades are dull, damaged, or missing,
rotate them if there is a sharp edge available;
otherwise replace blades.
2. Inspect condition of solenoid valve seats and
diaphragms according to valve disassembly di-
rections below.
3. Inspect pump and pump motor including pump
impeller for damage or broken vanes according
to disassembly directions below.
Solenoid Valve Disassembly
1. Disconnect power supply to machine at main
electrical panel and lock-out. Turn off water
supply.
2. Remove cap on top of coil. Remove coil.
3. Remove 4 hex bolts and lift bonnet from valve
body. Note positioning of spring and plunger.
4. Remove main piston.
5. Inspect for dirt, wear or lime build-up. Clean or
replace as required.
6. Reassemble in reverse of disassembly
Pump Disassembly
1. Before disassembling pump ensure there are
no obstructions in the pump intake.
2. The pump discharge has a union connection for
easy disassembly. Loosen the union connec-
tion to separate the pump from the discharge
piping.
3. Remove the pump impeller housing and impel-
ler by removing the 4 hex bolts attaching them
to the pump motor.
4. Inspect impeller for damage or excessive wear.
5. Repair or replace the pump parts as required.
6. Reassemble in reverse of disassembly.

NOTE:
LOCK-OUT of electrical power is
required prior to any maintenance proce-
dures. Shut-down the pulper according to
normal operation procedures and LOCK-OUT
electrical power at the electrical panel.
ANNUAL INSPECTION AUGER BRUSH:
1. Unbolt the 8 allen head screws at the top
of the extractor housing.
2. Remove the discharge chamber and
chute.
3. With gloves on, lift the screw and screen
out of the extractor.
4. Clean screw and screen with detergent
and hot water spray down.
5. Inspect both items for wear: The brush
attached to the screw should extend past
the screw approximately 1/8”. The screen
should be consistent thickness with a
consistent small hole pattern and no obvi-
ous wear points. If brush replacement is
required due to wear or damage follow the
directions in procedures section below.
Auger Brush Replacement
1. Unbolt Auger brush clamps.
2. Remove old brush.
3. Install new brush by rotating onto the screw and
aligning under the clamps.
4. Set brush to outside diameter 6 1/8”, which is
1/8” overlap with stainless screw flights outside
diameter.
5. Tighten bolts as you work down the screw.
6.
Reassemble in reverse of disassembly.
