HD2000 Battery-Powered Backpack Sprayer

Unpack your sprayer and the various parts & accessories from the box.

Charge your HD2000 before using it.

Prime your sprayer pump before the first use.

Add the liquid of your choice through the mesh strainer in the lid.

Dial in the pressure.

Squeeze the valve handle and spray continuously.

Turn off the pressure adjustment knob when you’re finished.

Check your knob.

Ensure that the pressure control knob is turned clockwise. The pump may be heard running as you increase pressure, but it may not make sound as it’s already built up enough pressure.

Check your voltmeter.

During normal operation, the green AND red lights of the voltmeter should stay on. If there are no lights and the unit is turned on, your battery may be discharged.

Check your pump.

Remember, the HD2000 uses a demand-style pump. This means it does not always run and make sound while the unit is on. It is possible to leave the unit on inadvertently and run the battery down. Priming also solves many pump issues.

Check your tank.

To do this, try plugging the charger into the unit. If the unit is charging, the charger light will turn red. When doing so, make sure that you are plugging the charger into a working outlet.

Check Your Battery.

Plug the charger firmly into the battery charger port on the base of the unit, then plug into a 110v outlet. Your battery will last many years but may need to be replaced eventually. 

Make sure the pressure gauge is turned counterclockwise to the OFF position, and that the battery charger is not plugged into the unit.

On the back of the unit, at the bottom, there’s a small battery compartment door under the back pad. Press the button to open this door.

There will be a red wire & a black wire attached to the battery. You can either remove the wires at the terminal or cut the wire close to the terminal with wire cutters. Make note of which wire was attached to the + and – terminals.

Slide the old battery out. Please recycle!

Place the new battery with the terminals oriented the same way as the old battery. Reattach the red & black wires as they were on the old battery.

Slide the new battery back in to the battery compartment & close the black plastic door until the button clicks.

Empty any remaining solution from the tank and rinse it thoroughly with clean water.

Fill the tank with a cleaning solution, such as water and vinegar or soap and water.

Pump the sprayer to circulate the cleaning solution through the hose and nozzle.

Let the cleaning solution sit in the tank, hose, and nozzle for 15-20 minutes.

Rinse the tank, hose, and nozzle with clean water and pump the sprayer to flush out any remaining residue.

Let the sprayer air-dry, and store it in a cool, dry place.

Add 1 gallon of warm soapy water into the tank.

Make sure that you use warm water and that you are adding the right amount of soap. Ideally, you should add around 2-3 scoops of liquid soap.

For optimal performance, we recommend priming the sprayer by running it for no more than 10 minutes. This ensures proper function without putting unnecessary strain on the pump.

Close the lid and turn on the unit.

Make sure that you have tightly closed the lid. Depending on what's causing the issue, you could have flow coming out of your hose within a few seconds to a few minutes.

Run 2 gallons of warm water mixed with 2 teaspoons of liquid dish soap through the unit to clean all internal parts, then run 1 more gallon of warm water only through. Spray until the unit, wand & hose are fully empty.

You may plug your HD2000 unit in for constant battery maintenance, or if this is not possible, simply charge fully before storage.

Place the unit right-side-up in the warmest storage possible. Do not store long-term in temps below 32°F.

Storage in its original closed box is ideal, but if that’s not an option, you can cover it with a canvas or plastic tarp to protect it.
