Common Task Force air compressor parts that you may need to replace
Pressure switch. The pressure switch turns the compressor on and off to regulate the tank air pressure.
Safety valve. Attached to the manifold, the safety valve pops open to relieve excessive air pressure when the pressure switch fails to shut off the pump at the cut-out pressure setting.
Unloader. The unloader is a valve installed between the pump and tank that opens to release pump head pressure when the compressor stops, enabling the compressor to restart easier.
Valve plate. Fixed above the cylinder, the valve plate controls air movement into and out of the cylinder to compress the air.
Check valve. Attached to the air tank inlet, the check valve prevents air from back flowing to the pump from the tank when the pump stops.
Troubleshooting your Task Force air compressor when it won't start with a full air tank
If the compressor won't restart after it fills the air tank, the check valve is likely stuck open. The check valve prevents tank air from back flowing to the pump. The stuck-open check valve causes high pump head pressure, preventing the compressor from restarting. Test the check valve by shutting off the compressor and pulling the ring on the safety valve to bleed the air from the air tank until it's empty. Turn on the compressor to fill the air tank. Bleed air out of the tank to reach the cut-in pressure so the pressure switch attempts to restart the motor to refill the air tank. If the compressor won't start with air in the tank, replace the check valve.
