Troubleshooting your HD2000 Battery-Powered Backpack Sprayer

Don't let a malfunctioning sprayer slow you down - use our comprehensive guide to troubleshoot and fix your HD2000 battery-powered backpack sprayer.

Step 1

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.

Step 2

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.

Step 3

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.

Step 4

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.

Step 5

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. 

How To Change your Sprayer Battery?

Your HD2000's lead acid battery uses tried-and-true technology that will give you many years of safe use. With repeated use, you may notice that your battery loses its ability to hold a charge or provides only enough power for short-term jobs. You can purchase brand-new batteries from the PetraTools website. Here's how to remove & replace an existing battery:

Step 1

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

Step 2

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.

Step 3

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.

Step 4

Slide the old battery out. Please recycle!

Step 5

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.

Step 6

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

How To Clean your Sprayer?

Maintaining a clean HD2000 Battery-powered Backpack Sprayer will keep it in good working order. Here's how:

Step 1

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

Step 2

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

Step 3

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

Step 4

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

Step 5

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

Step 6

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

How To Prime the Pump?

Priming your HD2000 Battery-Powered Sprayer is quite easy. Just follow these two steps:

Step 1

Add 2 gallons 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.

Step 2

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.

Nozzle Support Guide

Every HD2000 comes with six versatile nozzles to help you tackle your toughest spraying jobs. You can purchase additional nozzles at our website. Here’s what each of your new HD2000 nozzles can do:

Red Cone Nozzle

Can reach 8-10 feet with a soaking shower. You can also adjust it for a finer mist.

Triple Head Misting Nozzle

Lets you cover a large area with a medium-fine mist. Perfect for watering young or delicate plants.

Single Misting Nozzle

Has a very fine mist, perfect for flower beds or indoor greenhouse plants.

Yellow Flat Tip Nozzle

This delivers a nice, even, and wide fan of liquid which is perfect for green grass paint or mulch paint. If precise application of a solution is required, this nozzle is your best choice.

Black Single Nozzle

Works just like the brass nozzle but is better for caustic solutions. Perfect for a variety of applications, from fine mist up to a straight stream, with a twist of the nozzle.


The battery on your HD2000 is designed to provide up to 3 hours of continuous spray time on a single charge. To ensure the longest battery life possible, make sure to fully charge the battery after each use and store it in a cool, dry place.

How To Prepare your Sprayer for Winter Storage ?

Before you put your sprayer away for the winter, there are a few things you should do to make sure it’s in good shape for next season.

Step 1

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.

Step 2

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

Step 3

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

Step 4

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.
