2. Safety Information
Operating a pressure washer requires adherence to safety guidelines to prevent injury or damage. Please read and understand all safety instructions before use.
- Personal Protective Equipment: Always wear appropriate personal protective equipment, including eye protection (safety glasses or goggles), hearing protection, and sturdy footwear, when operating the pressure washer.
- Electrical Safety: Ensure the power cord is plugged into a grounded electrical outlet. Keep all electrical connections dry and away from water. Do not operate the pressure washer with wet hands or while standing in water.
- High Pressure Hazard: The water stream from the pressure washer is very powerful. Never point the spray gun at people, pets, or electrical outlets. Maintain a safe distance from the cleaning surface to avoid damage.
- Stability: Ensure the pressure washer unit is placed on a stable, level surface during operation to prevent tipping. The unit features an anti-tipping design for enhanced stability.
- Water Supply: Always ensure a continuous and adequate water supply to the unit before turning it on. Running the pump dry can cause damage.
- Purging Air: It is critical to purge all air from the system before starting the motor. Running the machine before purging air will damage it.
- Residual Water Drainage: Before turning off the machine for storage, especially in cold weather, purge all residual water from the pump, hose, and spray gun. Disconnect the water source, turn off the machine switch, and then press the pressure washer gun switch until all water drains.

5. Operation
Your LWQ Electric Pressure Washer is equipped with four quick-connect nozzles and a foam cannon for various cleaning applications.
5.1 Nozzle Selection and Use
Choose the appropriate nozzle for your cleaning task. To change nozzles, pull back the collar on the spray gun's quick-connect fitting, insert the desired nozzle, and release the collar to secure it. Ensure the machine is off and the trigger is not engaged when changing nozzles.
- 0° (Red Nozzle): Produces a concentrated, powerful jet stream. Ideal for tough, stubborn stains, cracks, and hard-to-reach areas. Use with extreme caution as it can damage surfaces if not used properly.
- 15° (Yellow Nozzle): Creates a focused, fan-shaped spray. Best for intense cleaning on hard surfaces like concrete, brick, and asphalt.
- 25° (Green Nozzle): Provides a wider, fan-shaped spray. Suitable for general cleaning on wood decks, fences, siding, and patios.
- 40° (White Nozzle): Delivers the widest, most gentle fan spray. Ideal for delicate surfaces such as windows, vehicles, and outdoor furniture.
- Foam Cannon (Black Nozzle): Used for applying detergent or soap. Fill the detergent bottle with appropriate pressure washer detergent. The cleaner will not pass through the pump, ensuring the pump's longevity.

5.2 Starting and Cleaning
- Turn On: Once the water supply is connected and air is purged, turn on the power switch on the pressure washer unit.
- Engage Trigger: Point the spray gun at the surface to be cleaned and press the trigger to begin spraying.
- Cleaning Technique: Start cleaning from top to bottom, maintaining a consistent distance from the surface. Use sweeping motions to ensure even coverage. For stubborn dirt, you may need to get closer, but always test on an inconspicuous area first.
- Safety Lock: When not actively spraying, engage the safety lock on the spray gun to prevent accidental discharge.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your pressure washer.
- Inlet Filter Cleaning: Periodically check the inlet filter for debris and clean it regularly to ensure maximum performance and prevent pump damage.
- Hose and Attachment Inspection: Regularly inspect all hoses, nozzles, and connections for signs of wear, cracks, or breakage. Replace any damaged parts immediately.
- Winterization/Storage: If storing the pressure washer in an area where temperatures may drop below freezing, it is essential to completely drain all water from the pump, hose, and spray gun. Disconnect the water source, turn off the machine, and then press the spray gun trigger until no more water comes out. This prevents internal damage from freezing water.
- General Cleaning: Wipe down the exterior of the unit with a damp cloth after each use to remove dirt and grime.
