1.3 Attaching Backpack Straps and Cart

The sprayer can be used as a backpack or with the included cart for easy mobility. The backpack straps are double-padded and fully adjustable for comfort, even when the tank is full. Ensure the straps are securely attached and adjusted for a comfortable fit before filling the tank.

The 4-gallon tank is custom molded to lock perfectly into the commercial-grade cart. To transition from cart to backpack, remove the two thumb-turn screws and lift the cart off the frame.

1.4 Connecting the Hose and Wand

Connect the hose to the sprayer's outlet near the bottom of the tank. Screw the wing-nut end of the hose clockwise until it is securely tightened. Then, attach the black squeeze handle to the other end of the hose, ensuring it is also securely tightened. Finally, screw the extendable wand onto the squeeze handle until it is secure. The wand reaches up to 34.5 inches, useful for hard-to-reach areas.

2. Operating Instructions

2.1 Priming the Sprayer

Before adding your solution, fill the tank with a small amount of water. Turn the sprayer on using the red switch. Squeeze the handle for a few seconds to ensure all parts function correctly and remove any air from the system. Empty the water after priming.

2.2 Adding Solution

The sprayer features a wide-mouth lid with a built-in filter to prevent debris from entering the tank. The secondary lid includes a built-in measuring cup for precise mixing. Fill the tank with your desired solution, following any specific mixing instructions provided with the solution.

2.3 Nozzle Selection and Pressure Adjustment

The PetraTools HD4000 comes with 6 different PetraFlow nozzles to suit various spraying needs:

• Shower Head Nozzle: High-volume release.
• 2-in-1 Mist to Stream Nozzle: Adjustable by twisting.
• Double Head Mist Nozzle: Dual mist for large area coverage.
• Single Head Mist Nozzle: Produces a very fine mist.
• Fan-Flat Nozzle: Creates a flat fan spray pattern for even coverage.
• Brass Nozzle: Adjustable from fine mist to long-distance spray. Not suitable for acid or bleach solutions.

The sprayer features a variable PSI adjuster, allowing you to effortlessly adjust pressure between 40 and 90 PSI with a simple turn of the dial. For maximum PSI, turn the sprayer on with the red switch. The manual recommends using either the dial or the red switch, but not both simultaneously.

3. Maintenance

Regular maintenance ensures the longevity and optimal performance of your PetraTools HD4000 sprayer.

After each use, especially when spraying chemicals, thoroughly rinse the tank, hose, and wand with clean water. Operate the sprayer with clean water for a few minutes to flush out any residual chemicals from the pump and nozzles. This prevents clogging and corrosion.
