Operational Checks, 3000
1. Check red light on the control module.
•
The red light is on whenever the unit is moving, or the traction control linkage is not in neutral.
•
The red light is on while the unit is aerating.
If the red light is not on, check the transport switch, and the switch wiring. This is the bottom switch on the
hydrostatic pump control lever. Repair or replace the switch or wiring as needed. If the switch and wiring is OK,
contact your distributor.
2. Check the yellow light on the control module.
•
The yellow light is on whenever the following conditions are met.
•
Water supply pressure over 20 psi.
•
Wheels up.
•
Accumulator pressure over 1800 psi.
If the yellow light is not on, check the water inlet pressure at the pressure gauge. If pressure is inadequate,
check the pre-filter, main water filter, and supply hose. If the water pressure is adequate check the pump start
limit switch, this is the switch on the transport axle. The switch should be closed when the wheels are up, (unit
down).
Replace switch as needed.
The final check is the accumulator pressure. If accumulator pressure is below 1800 psi the accumulator switch
will be open and the light will not be on. Contact your distributor to have accumulators checked or serviced.
3. Check the Green light on the control module.
•
The green light is on when the aerate switch is pressed.
•
This light stays on while the unit is aerating.
If this light does not light when the aerate switch is depressed check the switch and wiring. Repair or replace as
necessary.
