• Ensure that the pump is properly primed with water. Remove the cap from the
pump prime port and fill the pump as needed (
Figure 2
). If foaming mixtures have
been used in your QTAC recently, ensure that all the foam has been forced from
the pump by continually pouring water into the prime port until all the foam has
been displaced.
• Check the piping on the suction side of the pump to ensure that no air leaks are
present.
• For further troubleshooting information, see the pump Instruction Manual.
Water Will Not Discharge from The Discharge Hose
• Ensure that the pump engine is running and operating at a sufficient speed.
• Ensure that water pressure is available at the discharge hose port. This can be
checked by removing the hose connection at the discharge hose port.
• Check for hose kinking in the discharge hose.
• Ensure that the discharge hose shut-off valve is open.
• Ensure that the discharge hose nozzle is open.
The Pump Engine Runs Erratically
• Ensure that the engine has adequate fuel. Low fuel levels and operation over
rough and/or sloping terrain can cause the engine to momentarily run out of fuel.
• If the fuel has been stored for any length of time (and it has not been stabilized),
drain the fuel system and fill with fresh fuel.
• Proper engine performance is strongly dependent on a clean, lightly oiled air
filter. If the air filter is dirty or lacking oil, remove it from the air cleaner assembly,
clean with soapy warm water, rinse with fresh water and dry thoroughly. Once
dry, lightly saturate the element with clean engine oil and reassemble the air
cleaner assembly.
