Because the Chapin 63985 battery operated backpack sprayer is a general use sprayer, you have the option to use it for many different applications, BUT… you should never mix the applications.

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.




Plant Food

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.

Fungicide and Pesticides

You can spray both fungicide and pesticides with this sprayer outdoors.


Reduce weeds and any other unwanted plants in your yard, garden or field by spraying herbicides.

Indoor Household Use

You can use detergents and warm water in the sprayer to clean counters, carpets, floors, glass and ceilings.  Once again, ensure that the unit is well cleaned of any other chemicals before using it for general cleaning.

Outdoor Household Use

Great for cleaning windows, fences and siding.

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.
