7. Priming the System
Sometimes the pump will pick up air in the line from emptying the
tank. To achieve full pressure and volume the air must be
displaced out of the pump. After refilling this may be achieved by
following these steps:
1) Be sure the pump is on, using the on/off switch.
2) With the spray adjustment lever in the upper position (pin
stream), squeeze trigger to start liquid flow.
3) Using the spray adjustment lever, turn downward to a light
fan spray. You will hear a "spitting" noise as the air is
being discharged out of the end of the spray gun. Then
move the spray adjustment lever back to the upper position
on full pin stream, the pump should begin to build full
pressure. While pump is running, turn red priming valve on
top of the tank, in the cross line position (+) for
approximately one second then back to the in-line position.
This will also usually displace any remaining air in the line
and reacquire full pressure.
4) If needed, repeat steps 2 and 3. Also see the
TROUBLESHOOTING tips on page 16 of this manual.
