How to use

CUT-Carefully cut the two white zip ties securing the hose and pump handle with scissors. Use caution not to cut the white hose.

CONNECT- Unwind the hose. Firmly push the connector at the end of the hose into the spout on the pump until it locks into place.

EXTEND WAND- Lift sprayer wand off bottle. Push the yellow button while pulling out on the wand nozzle tip. Fully extend the wand until the yellow button snaps into the "SPRAY" position. NOTE: white trigger will not function until the wand is fully extended and the yellow button is fully visible in the "SPRAY" position.

PUMP- Make sure the handle is screwed on TIGHTLY or the bottle will not pressurize. Pump the handle 25-30 times to pressurize the bottle. A full bottle requires fewer pumps than a half full bottle. Pumping to the higher range will provide longer sprayer duration. After pumping, push pump down & turn handle clockwise to lock into carrying position. NOTE: This bottle is designed to expand under pressure & cannot be over-pressurized.

SPRAY- Aim wand. Spray by pushing down the white trigger with your thumb. Adjust spray pattern by rotating the white nozzle tip one half rotation. Spray weeds until thoroughly wet.

STORE- When finished spraying, push the yellow button and push wand until the yellow button snaps back into the original storage position. Place the wand back onto the bottle with the nozzle facing down.

DEPRESSURIZE- Push pump handle all the way down and turn pump handle and cap counter-clockwise to relieve pressure, then re-tighten prior to storing.
