TROUBLESHOOTING 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 symptoms, possible
causes, and the corrective actions to take.
1. Foam in tank and air entrainment:
The mixture of dry materials with water will sometimes cause excessive foaming, while
other dry materials with water mixes will cause air entrainment. These situations will reveal
themselves with the occurrences of an erratic slurry discharge, a drop in pressure of the
discharge, and a drop off in distance of slurry discharge.
Some solutions are:
A. As slurry level drops in tank, slow the agitator.
B. Add 2 to 3 oz. (59 to 89 ml) of an anti-foaming agent to tank.
C. If you can determine which additive is causing the air problem, either add it last or
not at all – unless it is the water.
D. Reduce recirculation time as much as possible.
2. Plugging or clogging:
Turn off engine and disconnect battery cables before working on
equipment. Failure to comply could result in death or serious injury.
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. To remedy this, see
FOAMING OF SOLUTION AND LACK OF DISTANCE SECTION. Plugging is caused by
either foreign objects or de-watered fiber. Plugging can occur in any of four places: the
valve and recirculation nozzle, the discharge nozzle, the pump area, and the sump area.
If plugging does occur, perform any of the following tasks to clear the obstruction:
A. Obstruction in discharge nozzle is determined by a change in or stoppage of the spray
pattern. To clear an obstruction, perform the following steps:
1. Disengage (turn off) the slurry pump clutch.
2. Remove
nozzle.
3. Clean the discharge nozzle. To clean the discharge nozzle, use the nozzle cleaning
rod attached to the underside of the guard rail. Insert the nozzle cleaning rod into
nozzle to push and buildup out of the nozzle. Repeat procedure until nozzle is
completely cleaned.
Before loosening any clamps, determine if the pipe is hot. If so, let it
cool before attempting to perform repairs. Failure to comply could
result in death or serious injury.
B. If the recirculation system is not working:
1. Disengage (turn off) the slurry pump clutch and stop engine.
2. Remove clamps attaching recirculation valve.
3. Slide rubber seals back and remove valve assembly.
4. Check valve assembly, recirculation nozzle in discharge pipe, and recirculation
pipe going into tank. Clear any obstructions.
5. Replace valve assembly and slide seal back into place. Lubricate outside of seals.
6. Replace
clamps.
