Substance is too thick for the sprayer. These sprayers are not designed to spray liquids with thicker viscosities (i.e., paint, stains, some sealers, etc.). They are ideal for herbicides, insecticides, pesticides, fungicides, fertilizers, and other chemicals with the consistency of water (Caution: Never use flammable liquids, caustics, acids, or hot water in these sprayers.) Please contact our customer service if you have a question regarding a specific chemical.
Flat seal (for flat fan tips) is missing or damaged. Remove the nozzle from the wand and then remove the flat fan tip from the cap nut. Make sure there is a flat seal at the bottom of the cap nut. If it is missing or damaged, it can be ordered with the poly nozzle kit or the brass nozzle kit.*
Sprayer wand or nozzle is clogged. Remove the nozzle from the wand. Flush wand, shut-off and nozzle with clean, cold water.
Dirt or debris in the shut-off valve. The valve is located inside the handle, so the first step is to depressurize the sprayer and release all liquid from the wand. Then unscrew and remove the shut-off assembly from the black rubber grip and hose (See Figure 7). It will come apart right above the section that reads “FILTER”. Remove the white filter inside the handle and flush with clean, cold water to remove any debris. Then flush cold water through the shut-off poppet (metal rod located within yellow nut). Press the shut-off lever (like you would as if you were spraying) for the poppet to open and allow the water to flow through. Lastly run cold water through the handle and hose.
