Toro 09802 Operator's Manual page 36

Problem
The engine is running and the unit is not
producing aeration holes (the pump or
water valve will not start).
The unit stops aerating in one direction or
stops aerating in the lowest hole spacing.
The unit is not producing aeration holes
(the pump and valve are operating
correctly).
The unit is not producing aeration holes
(the injection pump stops after the unit
stops moving).
The holes are shallow or the improper
depth.
Possible Cause
1. The supply hose is kinked, there is a
restriction in the line, or the valve at the
water source is only partially opened.
2. There is inadequate water pressure or
flow from the source.
3. Check the water pressure at the gauge
when the pump is engaged if the water
pressure drops to less than 25 psi, but
was initially higher.
4. Low accumulator pre-charge pressure
(low pressure indicator light is on).
5. High accumulator pre-charge pressure
(high pressure indicator light is on).
1. The supply hose is kinked, there is a
restriction in the line, or the valve at the
water source is only partially opened.
2. There is inadequate water pressure or
flow from the source.
3. Check the water pressure at the gauge
when the pump is engaged if the water
pressure drops to less than 25 psi, but
was initially higher.
4. The neutral switch tab is out of
adjustment.
1. There is air in the system.
2. A nozzle(s) is plugged.
3. The soil composition is hard.
1. This is a normal condition of the neutral
interlock system.
1. There is air in the system.
2. If the hole depth was satisfactory
earlier, check the density and moisture
content of the soil.
3. The soil composition is hard.
4. There are too many large nozzles,
causing a loss in pressure which could
damage the accumulator or other water
system components.

Corrective Action
1. Correct the condition.
2. Check the water pressure (from the
water source) at the inlet (8 gpm - 40
psi).
3. Replace the water filter.
4. Have the system serviced by an
Authorized Toro Distributor.
5. Have the system serviced by an
Authorized Toro Distributor.
1. Correct the condition.
2. Check the water pressure (from the
water source) at the inlet (8 gpm - 40
psi).
3. Replace the water filter.
4. Adjust the switch tab until the red
traction light is ON while the traction
bail is actuated in both directions.
The red traction light must be OFF,
when in neutral, to allow the engine
start interlock to function.
1. Open the main bleed valve to purge air
from the system.
2. Inspect the nozzles.
3. A different nozzle configuration
may be required.Have the water
system checked by an Authorized Toro
Distributor.
1. The operator must hold the Engage
(start) button to aerate without moving.
1. Open the main bleed valve to purge air
from the system.
2. A different nozzle configuration may be
required.
3. A different nozzle configuration may be
required.
4. Open the bleed valve and examine the
nozzles. Verify the size and quantity
per the recommendation chart. Have
the water system checked by an
Authorized Toro Distributor.
