Ortho Lawn Sprayer Instructions

By Sommer Leigh ; Updated September 21, 2017

Ortho's 2-gallon lawn spray can be used for a variety of chemical application uses including weed control, insect control, deck or patio applications, removing wallpaper, sealing concrete and appling cleaners and disinfectants. Basic instructions for using the device are similar no matter what chemical is being applied, but you should always follow the specific instructions for the chemical you are using, including proper safety precautions.

Pour clean water through the Ortho lawn sprayer's wide-mouth funnel at the top of the sprayer until the sprayer is about half full.

Tighten the lid on the Ortho lawn sprayer.

Pressurize the Ortho lawn sprayer by pulling the pump on the top of the lid up and down until the pressure feels consistent.

Test the Ortho lawn sprayer's output on a hard, flat area such as a driveway. Release the spray by pressing the lever on the wand. Walk at the same pace you will be walking when applying the chemical.

Rotate the Ortho lawn sprayer's nozzle tip to adjust the spray pattern until it feels comfortable to you and sprays in a consistent pattern.

Pour out the water from the Ortho sprayer on the lawn and fill with the chemical you choose to use.

Adjust the Ortho lawn sprayer nozzle as necessary when you are applying the chemical if it does not spray evenly or at a consistent, easily controlled pace.
