TROUBLESHOOTING YOUR HYDROSEEDER
®
Because of the tremendous work load usually placed upon the HydroSeeder
®
, minor
malfunctions will occur from time to time. If 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 occurences of an erratic slurry discharge, a drop in discharge
pressure and a drop off in slurry discharge distance.
Some solutions are:
A. As slurry level drops in tank, slow the agitator speed.
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 will 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 of the Troubleshooting
Chart. Plugging is caused by either foreign objects or dewatered fiber mulch. Plugging
can occur in any of four places: the valve and recirculation nozzle, the discharge nozzle,
the slurry 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 and shut down the engine.
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 the nozzle to push any buildup out of the nozzle. Repeat
procedure until nozzle is completely cleaned.
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 to perform repairs. Failure to comply will result in severe personal
injury or death.
