Safety Information
Always observe the following safety precautions when using high-pressure equipment:
- Eye Protection: Always wear ANSI Z87.1 approved eye protection to shield against high-pressure spray and debris.
- Hand Protection: Wear appropriate gloves to protect hands from chemicals and high-pressure water.
- Foot Protection: Wear closed-toe, non-slip footwear.
- Never Point at People or Animals: High-pressure spray can cause severe injury.
- Check Connections: Ensure all connections are secure before operating the pressure washer.
- Use Correct Nozzle: Always use the correct nozzle for the task to prevent damage to surfaces or injury.
- Read Pressure Washer Manual: Refer to your pressure washer's instruction manual for additional safety guidelines and operating procedures.
Setup
- Ensure Power is Off: Before attaching or detaching any nozzle, ensure your pressure washer is turned off and depressurized.
- Identify Inlet: The Dixon NZ4040S nozzle features a 1/4" male threaded inlet.
- Connect to Wand/Gun: Thread the nozzle securely onto the female 1/4" quick-connect fitting of your pressure washer wand or spray gun. Hand-tighten first, then use a wrench on the hexagonal flats of the nozzle for a snug fit, if necessary, to prevent leaks. Do not overtighten.
- Check for Leaks: Once connected, slowly turn on the water supply and check for any leaks at the connection point before starting the pressure washer.
Operating Instructions
The NZ4040S nozzle is specifically designed for applying soap or detergents at high pressure. Its 40-degree fan spray pattern provides broad coverage suitable for pre-soaking surfaces.
- Prepare Detergent: Ensure your pressure washer's detergent tank is filled with the appropriate cleaning solution, or that your siphon tube is correctly placed in a detergent container.
- Start Pressure Washer: Follow your pressure washer's instructions to start the unit.
- Apply Soap: Point the nozzle at the surface to be cleaned, maintaining a safe distance. Squeeze the trigger on your spray gun to begin applying the soap solution in even, overlapping passes. The 40-degree fan spray will ensure good coverage.
- Allow Dwell Time: Allow the detergent to dwell on the surface for the recommended time as per the detergent manufacturer's instructions, without letting it dry.
- Rinse: After soap application, switch to a rinsing nozzle (e.g., a 25-degree or 0-degree nozzle, depending on the task) to thoroughly rinse the surface.
Maintenance
Proper maintenance ensures the longevity and optimal performance of your nozzle.
- Cleaning: After each use, especially when using detergents, rinse the nozzle thoroughly with clean water to prevent chemical buildup and corrosion.
- Inspect for Clogs: Periodically inspect the nozzle opening for any debris or mineral deposits that may cause clogging or an irregular spray pattern. Use a nozzle cleaning tool or a thin wire to clear any obstructions.
- Storage: Store the nozzle in a clean, dry place when not in use.
- Inspect for Damage: Regularly check the nozzle for any signs of wear, cracks, or damage. Replace the nozzle if it shows significant wear or damage to maintain safe and effective operation.
