No water flow from spray gun when trigger is pulled

  1. Check to see if the Safety Lock is engaged/locked position. There’s a black or blue button on the handle of the spray gun. If the trigger lock is engaged, the trigger cannot be pulled in to create water flow.
  2. If trigger lock is OFF, remove the lance from the gun and squeeze the trigger. If water flow occurs, the lance is plugged up. Use the wire cleaner to clear the blockage by inserting the wire into the end of the lance. Tap the end of the lance on a hard surface, to clear the debris out of the lance barrel. Look through both ends of the lance. You should be able to see light through it, which confirms the lance is no longer blocked. Reinstall lance into gun and squeeze the trigger to confirm water flow.
