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/floor use
EZ Sprayer™ is designed to withstand the most
demanding spraying needs. This heavy duty
European-designed sprayer is safe, easy-tooperate & incorporates shoulder straps for use
as a backpack sprayer. This sprayer is ideal
for applying liquid fertilizer, nutrients, insecticides, fungicides, disinfectants, etc. Powered
by a 12V battery, this sprayer is much more
efficient 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.

a battery, a mini-pump, a charger, a spraying
system (rubber tubes, switch, spraying rod,
nozzle), shoulder straps and rollers.

• Includes a compact mini-diaphragm
pump that is light-weight, highly pressurized
featuring a pressure limit protection switch
and made to last repeated uses.

clogging the nozzle. The triple screen can be
easily dismantled and cleaned.
T
• he under-voltage alarm will go
off if the battery power goes below 10.5V.
This protects the battery. The included charging adapter can be used as a 12V power supply
as well as a charging unit.

intelligent charging– constant current/constant voltage/maintenance and short-circuit/
over-current/inverse-connection protection.

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.
