Sometimes when a stoppage occurs, you will not be able to find anything in the line. When this hap-
pens, it means that the system became airbound instead of plugged. To remedy this, see “Foaming”.
Plugging can occur in any one of four places; the valve and recirculation nozzle, the discharge noz-
zle, the pump area and the sump area. The plugging is caused by either foreign objects or dewatered
fiber.
A. Obstruction in discharge nozzle is determined by a change or stoppage of the spray pattern.
a) Disengage (turn off) the clutch.
b) Remove the nozzle.
c) Clear the nozzle with the nozzle cleaning rod attached to the underside of the
guard rail (platform option only).
DANGER: Severe injury can result from opening clamps when piping is
hot. Before loosening any clamps, determine if the pipe is hot.
If so, let it cool before attempting repair.
B. If recirculation system is not working:
a) Disengage (turn off) lutch and shut down the engine.
b) Remove clamp attaching the recirculation valve.
c) Slide rubber seal back and remove valve assembly.
d) Check valve assembly, recirculation nozzle in discharge pipe, and recirculation
pipe going into the tank. Clear any obstructions.
e) Replace valve assembly and slide seal back into place. Lubricate outside of
seal.
f) Replace the clamp.
3. Obstruction in the pump, which can be determined by a drop in pressure. If drop in pressure is
accompanied by a frothy or whitish discharge stream, blockage is in the suction line or sump area.
To clear the pump:
A Disengage (turn off) clutch and stop engine.
B. Loosen suction pipe clamps. If there is material in tank, stuff a rag into the suction piping.
C. Remove the clamp closest to the pump.
NOTE: If no water comes out, it means the obstruction is in sump area.
E. Reach into pump and remove obstruction. If jammed, pump suction cover may have to be
removed.
F. Reassemble removing pipe “plug” in process.
G. Remove rag plugging the suction piping.
4. Obstruction in sump area, located at bottom of tank on inside where suction pipe is attached:
A. The easiest way to clear sump is to back flush through the discharge plumbing with the
water supply hose.
B. Another method is to remove drain plug and run a long pole through the opening and into
sump area. Remove obstruction and replace drain cap.
C. Use a pipe or pole through the loading hatch opening to dislodge obstruction
