Troubleshooting your HD-PRO Battery-Powered Backpack Sprayer

If you've tried turning the HD-PRO 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 red rocker switch is turned off. Leaving them turned on, especially when charging, will drain the battery.

Step 2

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 3

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 4

Check if there's any leak.

Leaking commonly occurs when the nozzle pieces have not been fully tightened. Connections can come loose over time, so check your nozzle connections and re-tighten them.

How To Change your Sprayer Battery?

The HD-PRO 2.0 battery uses a lithium battery. If your battery loses its charge or stops working altogether, replace it by following these steps:

Step 1

Open the clear cover at the front of the unit. 

Step 2

Press the eject button for the battery to slide out quickly.

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 do 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 HD-PRO2.0 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 HD-PRO 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.
