Thank you for purchasing EZ Sprayer™. Please familiarize yourself with the EZ
Sprayer User Manual for proper operation and maintenance of your new sprayer.

Overview
4 Gallon Battery-Powered backpack/oor use
EZ Sprayer™ is designed to withstand the most
demanding spraying needs. This heavy duty
European-designed sprayer is safe, easy-to-
operate & incorporates shoulder straps for use
as a backpack sprayer. This sprayer is ideal
for applying liquid fertilizer, nutrients, insec-
ticides, fungicides, disinfectants, etc. Powered
by a 12V battery, this sprayer is much more
efcient than a manual sprayer. EZ Sprayer can
be operated continuously for up to 10 hours &
spray up to 100 gallons of liquid on a single
battery charge which consumes only 0.3 kwh
of electricity.
cOmpOnents
The EZ Sprayer consists of a holding tank, a base,
a battery, a mini-pump, a charger, a spraying
system (rubber tubes, switch, spraying rod,
nozzle), shoulder straps and rollers.

TROUBLESHOOTING TIP
If the unit functions properly then just stops spraying, you probably have an air bubble in the unit.
This is simple to fix.

Remove the lid and reach your hand inside the unit through the
top 5” mouth. Remove the silver screen filter off of the bottom
of the unit by gently pulling up on it.

Pour a few inches of water into the bottom of the unit.

Take a garden hose and cover the opening where the silver screen was.
Turn on the hose while squeezing the trigger with the unit turned on.

This will push the air out and the unit will function properly.

Replace the silver screen.
