Troubleshooting your HD3000 Battery-Powered Backpack Sprayer

If you've tried turning the HD3000 Battery-Powered Backpack Sprayer on and it doesn't work, do this:

Step 1

Check the switch.

When not in use, make sure that the adjustable pressure power switch is turned off. Leaving them turned on, especially when charging, will drain the battery.

Step 2

Check if the lights in front of the unit are turning on.

There are two light colors on the front of the unit - green and red. The red light shows that the unit is on and green means that the battery is charged.

Step 3

Check if the battery is charged.

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 4

Bypass the battery.

To know if the battery is working or not, all you have to do is plug the charger into the unit. Then turn it on, bypassing the battery. If it still doesn’t work, then you may need a new battery or pump.

Step 5

Check the battery terminal connections.

There could be times that the battery terminals aren’t connected to the wires. To check such things, open the compartment at the back of the unit and take off the velcro strap. Check that both wires are connected properly to the battery & ensure that moisture hasn’t made its way into the compartment.

Step 6

Access the internal wiring.

If all of the above doesn’t work, you might want to check the wiring inside the base of the unit. To do this, separate the unit and the tank by removing the Phillips screws from the base, then inspect if the wires are connected properly.

Step 7

Check the internal wiring.

Checking the internal wiring is very important to ensure that all connections are in good condition. Find out if there are hanging or exposed wires, then fix them right away.

How To Change your Sprayer Battery?

The lead-acid battery found in your HD3000 is a durable, reliable technology that will provide many years of safe use. If your battery loses its charge or stops working altogether, replace it by following these steps:

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 into the battery compartment & close the black plastic door until the button clicks.

How To Clean your Sprayer?

It is necessary to keep your sprayer clean, especially after use. When your sprayer is clean, it will last longer and work more efficiently. To clean your sprayer, follow these steps:

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?

To prime the pump, follow these steps:

Step 1

Add 2 gallons of warm soapy water into the tank.

Add 2 gallons of warm tap water to the tank. To this add 2 teaspoons of liquid dish soap. Shake gently to mix.

Step 2

Tighten 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.

How To Prepare your Sprayer for Winter Storage?

Here are some things you should do with your HD3000 before winter comes:

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 HD3000 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.
