To Free a Stuck Inlet
Using either a screwdriver or your finger, push where shown in picture at right until inlet moves back and forth freely.
“Force Feeding” Pump
To remove trash that has been caught in the valves, the
unit can be force fed. With pump on and prime/spray knob turned to “prime” position, pour the appropriate solvent into the suction tube and then fold hose as shown. While
firmly squeezing the suction tube, slide hand down toward 
the pump and repeat until pump primes.*
* This procedure will only work if the inlet valve is free.
