TROUBLE SHOOTING NOTES
CHECKING THE WIRE CONNECTIONS:
- Make sure that your tank is empty and not pressurized.
- Loosen the bolt in the front of the sprayer.
- Slowly pull down the switch housing.
- You will see wires and you will want to make sure that the wires are connected near the pump and at the switch.
- Once you have verified that the wires are properly connected you will reattach the housing to the tank in the same manner you removed the housing.
PRIMING THE PUMP ( First time use or after long storage)
- Fill your tank at least ¾ of the way full with water. Make sure that the pump cylinder is completely submerged in water.
- Let the water sit in the tank for a few hours.
- Once your unit has sat for a period of time you can turn the switch to the on position. The l indicates the on position, the 0 indicates the off position.
- With the switch turned on, place a rubber band around the trigger of the shut off assembly to hold the trigger open, as if you were spraying.
- Let your unit run for @12-15 minutes. You may not receive a spray right away as your pump may run but may not build pressure. This is acceptable and part of the priming steps.
- You should receive a strong stream at the 12-15 minute mark.
- Your unit is now cleaned and primed and ready for use.
