SAFETY PRECAUTIONS
• User must read and understand entire instruction manual before operating this Sprayer.
• Never use flammable or combustible liquids, caustics, acids, or hot water in this Sprayer.
• Always wear appropriate personal protection equipment as instructed by chemical manufacturer when
using, preparing, handling, spraying, or disposing of chemicals. This includes at least goggles, gloves, and
protective clothing.
• Read and follow all instructions and cautions on label of products used in this Sprayer.
• To reduce risk of battery fire or bursts, use only Fountainhead Group Batteries that are in good condition
and have not been damaged.
• Do not use Batteries that are wet or have been damaged.
• Inspect Sprayer, Hose, Shut-off, and Wand, for damage or loose connections before each use.
• Do not pressurize with any mechanical device such as an air compressor since this can create a dangerous
pressure level and bursting of parts, resulting in serious injury.
• Always use replacement parts from the original manufacturer.
• Never attempt to alter Sprayer from original condition.
• Do not lift or carry the Sprayer by the Hose, Shut-off valve, or Wand. Carry by the Handle only.
• Only spray when the air is calm (no wind or air movement) to prevent chemical spray from drifting into
unintended areas.
• Keep the Sprayer and all chemicals out of the reach of children.
• Remove chemicals and thoroughly clean the Sprayer after each use. Failure to clean the Sprayer may
cause contamination of subsequent applications, will cause premature Sprayer wear, and void the Sprayer
warranty.
ABOUT THIS SPRAYER
WARNING: RISK OF FIRE, BURNS, OR ELECTRICAL SHOCK. To reduce the risk of injury, user must read
and understand entire instruction manual before operating this Sprayer.
This is an electric-powered backpack style Sprayer that is designed to spray water soluble solutions, such as
herbicides, pesticides, and other liquid chemicals typically used for weed prevention, weed remediation, pest
control, fertilizing, and watering.
This Sprayer uses a rechargeable Lithium-Ion Battery to power an electric diaphragm Pump, eliminating the
need for manual hand-pumping. Lithium-Ion Batteries are shipped in a reduced-charge state, and must be
charged prior to initial use. The Pump directly pumps the liquid contents from the Tank, through the Hose,
Shut-off, Wand, and Nozzle to create spray. Because the Pump directly pumps the liquid, it does not create
pressure inside the Tank.
To maintain optimal Pump and Battery life this Sprayer is designed to turn off the Pump when not spraying.
Because of this the Pump will turn on and off periodically during normal use. Typically the pump will turn
on when the Shut-off is opened (Lever depressed) and turn off when the Shut-off is closed (Lever released).
This is acheived via a pressure switch. If no liquid is present in the system then pressure can’t increase so the
pump will not turn off. Ensure that the Power Switch is set to the OFF position whenever the Tank is empty.

Cleaning & Storage.
In cases where after-market ultralow-flow nozzles are used, the Pump may turn on and off more frequently,
even when the Shut-off is open (Lever depressed). This is normal and is due to the use of an ultralow-flow
nozzle with the high-performance pump.
