Operating Instructions

1. Powering On/Off

Once the battery is installed and the tank is filled, you can power on the sprayer.

• To power on, locate the main power switch (usually green) on the control panel and flip it to the 'ON' position.
• The digital voltage display will show the real-time battery power. The system includes a 2.3V over-discharge auto shut-off to protect battery life.
• To power off, flip the main power switch to the 'OFF' position.

2. Adjusting Pressure

The sprayer offers dual-mode pressure control:

• The green switch defaults to 100 PSI for maximum pressure.
• To adjust pressure between 0-100 PSI, rotate the dedicated knob on the control panel. This allows you to fine-tune the spray from a fine mist to a powerful jet, depending on your needs.

3. Using the Auto Mixing Function

The exclusive one-touch auto-mixing button ensures consistent solution concentration.

• Press the mixing button (usually red) on the control panel to activate the internal mixer.
• This function instantly blends powders, liquids, and concentrates evenly, preventing sediment buildup and ensuring uniform application.
• Deactivate the mixer when not needed to conserve battery power.
