Avoid using a sprayer for general cleaning purposes if plant protection or herbicide chemicals have already been used in the sprayer. If a sprayer has been used for plant protection or as an herbicide, clean the sprayer completely (see cleaning section) before using.

Plant Food: Use different spray patterns for optimum foliage feeding or for fungicide and pesticide application.

Herbicides: Reduce weeds and unwanted plants but avoid using the same sprayer for plant feeding or protection without thoroughly cleaning (see cleaning section) the sprayer first.

General Household Use: Apply detergents, cleaning solutions, warm water (do not exceed 120°F/49°C) or nontoxic household cleaning chemicals for carpets, floors, walls, glass, counter tops, and ceilings. DO NOT use the sprayer that has been used with herbicides, pesticides or other toxic chemicals for household applications.

General Outdoor Use: Use the sprayer for cleaning windows or with a detergent for general purpose cleaning.

    This item is garbage

    By Brian on 07/02/2019

    I am now on my third 24 volt backpack sprayer period. They last about a week before they start malfunctioning.. first it starts that the pump doesn't kick off between engaging it to spray.. Followed by a couple days later it starts a streaming liquid out the bottom of the pump and sprayer through the battery and all over the back of whoever is using it period. This last one I exchanged lasted about three days.. I kept exchanging them because I couldn't get a refund but I am on my way to get a refund or I'm going to be thrown in jail. I can't believe they haven't had a recall on these things.. A quick Google search and I found out tons of people have the same exact problem

    Good sprayer, cheap wand

    By Nelson on 06/08/2018

    Overall sprayer is good. I like the fan tip and good pumping volume as it makes job go quickly. Only complaint is that on a sprayer this pricy they put a plastic wand that can get broken easily. Would have been nice to have steel wand but overall I like it and would buy again.

    Don't buy this sprayer

    By Shawn on 06/30/2020

    This is my second 24V Chapin Sprayer I have bought. I have been through 5x batteries and 2x chargers over 24 months. I am not sure what the defect is with this particular design. Others on have similar issues. The 20V model does not appear to be plagued with this many issues.
