Follow these steps to prepare your pressure washer for first use.

4.1. Assembly

1. Attach Handle: Secure the aluminum handle to the main unit. Ensure it is firmly locked in place.
2. Connect High-Pressure Hose: Connect one end of the 19-foot high-pressure hose to the pressure outlet on the unit and the other end to the spray gun. Ensure all connections are hand-tightened securely to prevent leaks.
3. Install Detergent Tank: If using detergent, attach the removable detergent tank to its designated port on the unit.

4.2. Water Supply Connection

1. Connect a standard garden hose (not included) to the water inlet on the pressure washer. The unit features a brass hose coupling.
2. Ensure the garden hose is free of kinks and obstructions.
3. Turn on the water supply completely.
4. Before plugging in the unit, press the trigger on the spray gun to purge air from the system until a steady stream of water flows out. This prevents air bubbles from causing issues during operation.

4.3. Electrical Connection

1. Plug the GFCI manual reset plug into a grounded 120-Volt outlet.
2. Press the "RESET" button on the GFCI plug. The indicator light should illuminate. If it does not, do not proceed and consult the troubleshooting section.

5. Operating Instructions

This section details how to operate your pressure washer effectively and safely.

5.1. Starting the Pressure Washer

1. Ensure the water supply is fully open and the GFCI is reset.
2. Turn the pressure washer's power switch to the "ON" position. The motor will run briefly to build pressure and then shut off. This is normal operation for the auto shut-off feature.
3. Point the spray gun at the surface to be cleaned, ensuring it is clear of people and objects.
4. Squeeze the trigger on the spray gun to begin spraying. The motor will restart automatically.

5.2. Using Spray Nozzles and Attachments

Your pressure washer comes with various attachments for different cleaning tasks:

• Narrow to Wide Spray Nozzle: This adjustable nozzle allows you to change the spray pattern from a concentrated stream for tough spots to a wider fan for general cleaning. Rotate the nozzle head to adjust.
• Turbo Lance with Orbital Spray: Provides a powerful, oscillating stream for aggressive cleaning of stubborn dirt and grime on hard surfaces like concrete.
• Turbine Driven Rotary Cleaning Brush: Ideal for scrubbing surfaces with less risk of damage, such as vehicle exteriors or delicate patio furniture.

To change attachments, ensure the pressure washer is off and the trigger is released to relieve pressure. Twist and pull the current attachment off the wand, then push and twist the desired attachment into place until it clicks securely.

5.3. Using Detergent

1. Fill the removable detergent tank with a pressure washer-safe detergent. Do not use harsh chemicals or solvents.
2. Ensure the detergent tank is securely attached to the unit.
3. For detergent application, typically a low-pressure nozzle or a specific detergent application setting on the adjustable nozzle is required. Refer to the nozzle instructions for specific detergent application modes.
4. Apply detergent to the surface, allowing it to soak for a few minutes (refer to detergent instructions), then rinse thoroughly with high-pressure water.

5.4. Shutting Down

1. Turn the power switch to the "OFF" position.
2. Turn off the water supply.
3. Squeeze the spray gun trigger to release any remaining pressure in the system.
4. Disconnect the garden hose and the high-pressure hose.
5. Unplug the GFCI from the electrical outlet.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your pressure washer.

• Cleaning Nozzles: Periodically clean the nozzle openings to remove any blockages. A small wire or nozzle cleaning tool can be used.
• Water Inlet Filter: Check and clean the water inlet filter regularly to prevent debris from entering the pump.
• Hose and Connections: Inspect the high-pressure hose and all connections for wear, cracks, or leaks before each use. Replace damaged parts immediately.
