Meaning…if you have used plant or herbicide chemicals already in the sprayer you should not then use it for general household cleaning purposes unless you have thoroughly cleaned the tank, hose and wand to ensure that there are no plant chemicals remaining.
You can use different spraying patterns for spraying plant food outdoors. If you have used your sprayer to for herbicides or pesticides, make sure that it has been well cleaned before you use it for plant food.

Chapin 63985 Features
This is a 4 gallon translucent poly tank which allows you to see the line of liquid in the tank so you know how much solution you have remaining for the job.
The tank opening is one of the widest in the industry with a 6″ cap for easy pouring.
Wand, Hose, Spray
The wand length is 20″ with a hose length of 4 feet (48″) to provide flexibility and easy mobility while you are spraying. The unit comes with three different spray nozzles: adjustable brass cone, ploy fan and poly-cone.
Provides a consistent 30 foot horizontal spray stream.
The PSI is a constant 35-40 psi as the battery power keeps the unit going. No up and down pressure fluctuations like you would have in a manual pump sprayer. Being battery powered, you will have consistent spraying for 1.75 hours.
Comes with padded shoulder straps, but no padding for the back.
Black & Decker 20 Volt Lithiun Battery
The batteries need to be charged for 3-4 hours before using and once they are fully charged you can work with a continuous spray for nearly 2 hours.
To charge the battery, plug in the charger and insert the battery pack. The green LED light will flash indicating that the battery is being charged. Once the battery is completely charged, the green light will stop flashing and will remain constantly on. You can now use the battery in your sprayer or leave it in the charger.
It is recommended that you recharge your battery immediately after use.

The Chapin battery powered backpack sprayer is well designed and they have partnered with Black and Decker to get a long lasting 20 volt battery.
This backpack sprayer will be working harder than you. Spraying weeds, plants, trees and pest just go easier.
They are using Black and Decker’s lightweight 20 volt rechargeable battery system which allows you to use 50 gallons in one single charge (roughly 1.75 hours of work).
The battery is small (and light) and has a compact, easy to carry charger.
You can also buy additional Black & Decker chargers from your local store if you feel the need to have an extra on hand.
The mouth has a wide 6″ opening which makes for less spills and splashes while pouring in your solutions. The mouth is also wide enough to fit a man’s hand so that you can reach inside and easily remove the intake filter for easier cleaning.
This system comes with three nozzles (distance, width or direct range). The battery provides a a 35-40 psi pressure.
I should mention that Chapin have built in a carry handle right into the cap, which is a really simple, but great feature.
1.75 hours of continuous spraying, that’s up to 50 gallons.
Offers 35-40 PSI with a 35-foot maximum horizontal spray stream.
6-inch wide mouth funnel for easy filling and cleaning with a carrying handle built right into the cap.
Weighs 39% less than competitive units. Santoprene seals in the pump for maximum chemical resistance.
Cushion grip shut-off with built-in, serviceable filter to assure that no debris can clog the nozzle tip.
Deluxe padded straps with waist/chest strap for prolonged use.
Additional batteries available through Black & Decker.
Probably the biggest comment when reading reviews about the Solo 417 battery backpack sprayer is the weight. Because it is a 6.6 gallon tank, it is going to be much heavier than those comparing it to a 4 gallon tank.
Many people have had issues with the battery not holding it’s charge, but you must give it 9-10 hours to charge for the first time before using it. Once you have done that, you should be good to go for 5-7 hours of work on a single charge.
Uses: Spraying pesticides, herbicides, and for general spraying. Do not use with bleach, chlorine or any disinfectants. If you need a backpack sprayer for bleach, click here.
When researching the Solo 417, I noticed that most of the negative comments were made in 2011 and 2012. Since then, Solo seems to have resolved the complaints (battery life, leaking, etc) as you will find that the more current customer comments are very positive.
Nozzles: This sprayer comes with three nozzles: a flat spray nozzle, a hollow cone nozzle and a jet stream nozzle. These three nozzles should cover your needs so you do not need to buy other nozzles.
Padded Straps: The sprayer comes with padded, adjustable straps.
PSI: Toggle switch to give you 36 psi or 62 psi provided through a 12 volt battery.
