Troubleshooting

Check the following:

• Ensure that the ON/OFF valve on valve block is in the “ON” position.
• Check that Speed Control Knob is turned to a full open position.
• Make sure screen/filter is free from rust, corrosion , or any restrictions
• Make sure the pilot valve stem has made contact with the shut off rod. The valve stem has to be shifted to the far right in order for the bellows to fill.
• With the stem in the far right position there should be no pressure in the line running from the top of the pilot valve to the front port of the valve block. To check for pressure turn water supply off. Remove plastic line that runs from top of pilot valve at the point where it is connected to the front of the valve block. Carefully turn the water back on and with the pilot valve stem shifted to the far right, there should be no water coming through the line. If line is pressurized the pilot valve is bad or is plumbed incorrectly.
• Carefully open the drain valve in the tee coming from the Bellows. If there is a good flow of pressurized water coming out of this drain, then the line to the bellows is clogged.
• If your unit is equipped with a quick exhaust valve, check to see if water is running through it. If water is running through the quick exhaust valve and not filling the bellows, the quick exhaust valve needs to be replaced.

Check the following:

• Carefully remove the tube from the elbow beside the high low valve. If pressurized water is coming from this line, valve block is faulty and should be repaired or replaced.
• If your unit is equipped with a quick exhaust valve, check to see if water is running through it. If water is running through the quick exhaust valve and not filling the bellows the quick exhaust valve needs to be replaced.

Check the following:

• Is the auto shut off valve at the sprinkler cart set in the run configuration
• Is the water supply pump and/or valves turned on
• Check for kinks or obstructions in the supply hose and lines
• The gauge could be faulty

What to do if the turbine will not run
Check the following:

• Check that the speed control linkage is working properly
• Check turbine filter for debris
• If you are trying to run the machine on a slower setting; make sure the drive belt on the turbine is on the smaller pulley and on the larger pulley on the gearbox.
• With water supply OFF, check to see if the turbine pulley spins freely by hand.
• Check to see if the sprinkler is operating correctly and if the correct nozzle size is being use.

Check the following:

• Ensure that the clutch pin is engaged into the clutch sprocket
• Check all pulleys and sprockets on machine

What to do if the booster pump generates low or no pressure boost:
Check the following:

• Pump impeller may be plugged.
• Suction line might be plugged.
• Check to see if there is enough flow – check the inlet gauge.

Check the following:

• The sprinkler has to shut off at the end of the run to activate the flow switch
• Faulty flow switch

What to do if the tube will not pull out:
Check the following:

• Is clutch pin disengaged on clutch sprocket?
• Spool brake adjusted too tight?
• Tube has become crossed or tangled from coasting
