4. Piping System Cleanout Procedure (Purging Line):
A. Remove discharge nozzle and gasket from discharge boom.
B. Aim discharge boom assembly into an open area away from any persons,
obstructions, or high voltage power lines.
C. Open discharge valve and close recirculation valve.
D. With the engine at low idle, engage (turn on) the slurry pump clutch with a firm
snap. Do NOT allow clutch to slip.
Do NOT engage the slurry pump clutch above 1000 RPMs or damage
to the slurry pump clutch will occur.
E. Increase engine speed to approximately 1/2 to 3/4 throttle.
F. When discharge stream is clear, open recirculation valve and close discharge
valve. After recirculation stream is clear disengage (turn off) the slurry pump clutch.
G. Replace gasket in discharge boom.
5. Continue filling tank with water.
6. Increase engine speed to full RPM.
7. Start loading dry material, loading the lightest material first. Agitator control should be in
full REVERSE for mixing.
A. Seed – Cut open the seed bag and dump contents into slurry tank. When using
inoculant, add it in the tank along with the seed. When using quick-swelling
seeds, load them just prior to application.
B. Wood Fiber Mulch – Empty the entire bag in or cut bag open and drop in the
sections of fiber. The amount of mulch to be used should be loaded by the time
the water level is at 3/4 full. If agitator stalls or a high pitch squeal comes from
the hydraulic system, reverse agitation to FORWARD for a moment to clear the
obstruction, then return agitation to REVERSE.
Hydraulic system will overheat if agitator shaft is jammed for extended
period. This will damage hydraulic oil and system components.
Keep hands and arms away from tank interior and agitator. Failure to
comply will result in death or serious injury.
C. Fertilizer – Stand over hatch opening and drop the bag onto the bagcutter. Grasp
both ends of the bag and dump material into slurry tank.
D. All other additives – Consult with manufacturer for proper loading technique.
8. When all materials are loaded and in suspension, and the tank is full, move the agitator to
NEUTRAL then full speed FORWARD to ensure all material is mixed. It may be necessary
to change the agitator direction more than once to ensure a thorough mixture.
9. Once the material is thoroughly mixed, place the agitator control lever in forward direction
to 1/4 speed, or just enough to create movement in all of the corners of the tank. Do
NOT over-agitate the slurry. Always discharge the material with the agitator control in the
FORWARD position and at slow speed.
10. Close hatch lid on slurry tank.
NOTE:
The slurry should not be recirculated for more than 15 minutes prior to
discharge to reduce wear and keep seed from swelling.
NOTE:
If foaming occurs, reduce agitator speed.
