How to Use

  • Step 1: Insure the tool holder is assembled to the tank adapter before mounting the discharge assembly. The Tool Holder snaps into the groove of the tank adapter. Insert the outlet tube portion of the discharge assembly into the tank adapter. Firmly insert the outlet tube portion into the tank adapter leaving no gap between the tank adapter and outlet tube adapter. Firmly tighten the retaining nut to the tank adapter. 
  • Step 2: Attach nozzle to shut-off handle or extension wand per Fig. 2A-2D depending on the style of extension wand included with sprayer.
  • Step 3: The filter helps prevent clogging while spraying. It is located on the end of the outlet tube inside your sprayer tank. To clean filter, remove the discharge assembly from the tank. Make sure the filter is positioned at the bottom of the tank.
  • Step 4: Snap shield onto wand as shown. Using the spray shield will help protect your plants etc. from over spray.

To Use The Pump

  • Step 1: Turn the pump handle counterclockwise and remove the pump. Fill the tank to no more than the proper gallon marker. Check the pump to make sure that no grass or dirt is stuck to the barrel. Replace the pump in the tank and tighten securely.
  • Step 2: Turn the handle clockwise to tighten. Push the handle down, turn 1/4 turn counterclockwise to release. Pump until you feel resistance.
  • Step 3: Push the handle, down, turn 1/4 turn clockwise to lock. Begin spraying. Re-pump sprayer as required to maintain spray force.
