Charge Your Sprayer Before Use

Make sure your HD4000 battery-powered backpack sprayer is fully charged before use. To charge, plug the battery charger into an outlet and connect the charger to the sprayer. The red light on the charger will turn green when the sprayer is fully charged.

2

Prime The Sprayer Pump

Before using your sprayer, you must first prime the pump. To do this, pour 2 gallons of warm water into the tank when using your sprayer for the first time. Turn on the sprayer and thoroughly saturate the area with water. Failure to prime the pump in this manner might result in poor pump performance at first.

3

Adjust The Sprayer Pressure Switch

The HD4000 has two pressure settings: high and low. The high setting is used for general spraying, while the low setting is used for more delicate tasks such as spraying flowers or seedlings. To adjust the pressure switch, turn the black knob on the side of the sprayer to the desired setting.

Read The Led Voltmeter

The HD4000 has an LED voltmeter that displays the battery’s voltage level. The LED voltmeter will be in the green zone when completely charged. The red light showing low charge indicates that the battery needs to be charged. Fully charge the battery by connecting it to a 110V outlet for 6 to 8 hours. Fill the tank with water and spray the device for at least 30 minutes to enable the voltmeter if it is not working when you arrive.

5

Pour Your Solution Into The Tank Through The Filter

Remove the cap from the tank and fill it with your desired solution. Be sure to use a funnel to avoid spills. Replace the cap and tighten it securely.

How to Troubleshoot the HD4000 Battery-Powered Backpack Sprayer

Although it rarely happens, there could be times when the HD4000 Battery-Powered Backpack Sprayer won’t turn on. In case this happens, here’s what you have to do:

Watch Now

Check the fuse.

To check the fuse, remove it from the control panel and take a good look at it. The fuse has a filament inside of it. Make sure that there is no burning inside and that the filament is attached correctly.

4

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.

5

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, then the battery will be bypassed already. If it still doesn’t work, then you probably need a new battery.

6

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.

7

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, then inspect if the wires are connected properly.
