TROUBLE SHOOTING GUIDE

Machine will not start when foot switch is depressed.

•  Check the throttle valve, be sure to adjust the valve to the proper speed for the cleaning device 

and the flexshaft size.

•  Check the air supply connection and the quick disconnect hose coupling.
•  Verify air supply connection to main piping is on.
•  Check the foot switch hose for kinks or pinch points.

Machine starts but loses power and/or speed.

•  Check for dirt or blockage in the air supply lines.
•  Check for the proper lubrication flow to the machine from the lubricator.
•  Verify the air supply has sufficient CFM (Liters per minute) to sustain the unit at speed.  For more 

information see “Air Supply” section.

•  If the machine has been in service for many hours, or has been supplied with dirty air, the motor 

may require a “Flush” operation.  See “Maintenance” section.

•  New vanes may be required if the machine has been in service longer than 5,000 hours.  (Ser-

vice Repair Kit 04230 is available.)

•  Remove machine cover and check the muffler for corrosion or restrictions.

Machine rotates but no water is flowing from the end of the flexshafting.

•  Check the flexshaft and machine connection.
•  Check the garden hose entering the machine for kinks or pinch points.
•  Check the water supply valve to verify that it is “on” and that water pressure is sufficient.

Water is leaking from the machine.

•  Check O-ring (part #P8309-25) in the Manifold Assembly (part #04213).  Replace if missing or 

worn.

•  Remove the machine cover and verify that the tube from the water supply to the manifold is in 

place.

•  Seals within the manifold are damaged or worn.  Replace with Manifold Assembly 04213 or call 

an Elliott service facility.

Flexshaft stops rotating.

•  Remove flexshaft from the machine and check the break-away coupling.
•  Check the connection of the flexshaft and the machine, be sure flexshaft manifold cap is se-

cured on manifold.

•  Remove the machine cover and check the coupling between the motor and the manifold for 

proper alignment and tightness of the set screws.
