TROUBLESHOOTING YOUR HYDROSEEDER
®
(CONTINUED)
Before loosening any clamps, determine if the pipe is hot. If so, let it
cool before attempting to perform repair. Failure to comply WILL result
in severe personal injury or death.
B. If the recirculation system is not working:
a) Disengage (turn off) the slurry pump clutch and shut down engine.
b) Remove two clamps on each side of the recirculation valve.
c) Slide rubber seals back and remove valve assembly.
d) Check valve assembly, recirculation nozzle in the discharge pipe, and the
recirculation pipe going into tank. Clear any obstructions.
e) Replace valve assembly and slide the seals back into place. Lubricate the outside
of the seals with grease.
f) Re-install the clamps.
3. Obstruction in the pump, which can be determined by a drop in pressure. If the drop in
pressure is accompanied by a frothy or whitish discharge stream, the blockage is in the
suction line or sump area. To clear the pump:
A. Disengage (turn off) the slurry pump clutch and stop the engine.
B. Loosen the suction pipe clamps. If there is material in the tank, shut off the suction
line valve.
C. Remove the clamp closest to the pump.
NOTE:
If no water comes out, obstruction is in sump area.
E. Reach into the pump and remove the obstruction. If jammed, the pump suction
cover may need to be removed.
F. Reassemble all removed components.
G. Open suction line valve.
4. Obstruction in sump area, which is located at the bottom of the tank on the inside
where the suction pipe is attached.
Three methods to remove an obstruction in the sump area are as follows:
A. Clear the sump by backflushing through the discharge plumbing with the water
supply hose.
B. Remove the drain plug and run a long pole through the opening and into the sump
area. Remove the obstruction and replace the drain cap.
C. Use a pipe or pole through the loading hatch opening to dislodge the obstruction.
Do not turn the pump shaft backward with a pipe wrench. This will
unscrew pump impeller from pump shaft. Consequently, when the
slurry pump clutch is engaged (turned on), the pump impeller will screw onto pump shaft
with a force great enough to break pump impeller. Failure to comply could result in minor or
moderate personal injury. Failure to comply could also result in product or property damage.
