15. With the clutch still engaged, open the discharge valve.
CAUTION: To decrease pump wear and increase discharge distance, it
may now be desirable to close the recirculation valve.
However, the recirculation valve must be open BEFORE
closing the discharge valve if the application of slurry is to be
interrupted. Extreme heat, which will cause damage and/or
bodily injury, will occur if both valves are closed.
16. Apply the slurry (see “Application of Slurry” pages 17-18).
17. If another load is to be applied, start again at step “1”. If finished, follow the clean-up procedure.
TROUBLE SHOOTING YOUR HydroSeeder
®
:
Because of the tremendous work load usually placed upon the HydroSeeder
®
, minor malfunctions will
occur from time to time. If these are not remedied immediately, they could lead to poor performance and
damage to the equipment. This section describes possible problems and the action to correct them.
1. Foam in the tank and air entrainment.
The mixture of dry materials with water will sometimes cause excessive foaming while others will
cause air entrainment. This is noticed primarily in the erratic discharge and a drop in pressure and
distance.
Some solutions are:
A. As the slurry level drops in the tank, slow the agitator.
B. Add 2 or 3 ounces (4 to 6 cl) of an antifoaming agent to the tank.
C. If you can determine which additive is causing the air problem, either add it last or not at all -
unless it’s the water.
D. Limit recirculation time as much as possible.
E. Open pump suction bleed valve to exhaust air trapped in the pump or suction line. Close valve
as soon as the air stops.
2. Plugging or clogging:
DANGER: Turn off engine and disconnect battery cables before working
on equipment. Serious injury or death can result from moving
parts or high pressure spray.
Sometimes when a stoppage occurs, you will not be able to find anything in the line. When this
happens, 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 nozzle, the pump area and the sump area. The plugging is caused by either foreign objects
or dewatered fiber.
A. Obstruction in the discharge nozzle is determined by a change or stoppage of the spray pattern.
a) Disengage clutch.
b) Make certain that the pump has stopped rotating.
