Safety First

Before you begin learning how to use a Westinghouse pressure washer, safety must always be your top priority. Pressure washers deliver water at extremely high pressures that can cause serious injury or property damage if mishandled. Always wear protective gear including safety glasses, work gloves, and closed-toe shoes with good traction. Never point the nozzle at people, pets, or electrical outlets. Keep bystanders at least 50 feet away during operation. Make sure the area around the washer is dry before starting, and never operate the machine indoors or in enclosed spaces due to carbon monoxide risk from gas-powered models.

Personal Protective Equipment

The right protective equipment prevents injuries when using a pressure washer. Safety glasses protect your eyes from debris and chemicals. Hearing protection may be needed for extended use since pressure washers can be loud. Work gloves improve grip and protect hands from scratches. Long pants and closed-toe shoes prevent cuts and burns. Some users prefer earplugs and dust masks depending on the cleaning chemicals being used.

Tools and Supplies You Will Need

Having the right tools and supplies ready makes the setup process smoother. Here is what you typically need:

• Water source with adequate flow rate
• Garden hose or dedicated pressure washer inlet hose
• Appropriate nozzles for different cleaning tasks
• Cleaning detergent compatible with your washer
• Protective gear as mentioned above
• Flat head and Phillips head screwdrivers for adjustments
• Towel or rag for drying connections
• Fuel container if using a gas model
• Engine oil appropriate for your climate

Initial Inspection and Unpacking

When you first bring your Westinghouse pressure washer home, take time to inspect all components carefully. Remove all packaging materials and verify that every part listed in the manual is present. Check the pump, engine, hoses, and nozzles for any signs of damage that may have occurred during shipping. Look for dents, cracks, or loose connections. If you find any issues, contact the manufacturer or retailer before proceeding with setup.

Checking Serial Number and Warranty

Locate the serial number on your unit, usually found on a metal plate near the engine or pump. Register your product online with Westinghouse to activate the warranty. Keep a copy of your receipt and the serial number in a safe place for future reference. Registration often provides access to customer support and updates about your specific model.

Connecting the Water Supply

Connecting the water supply correctly is crucial for proper operation. Most residential pressure washers require a standard garden hose connection. Attach the provided inlet hose to a water spigot, ensuring the water pressure is adequate—typically at least 20 PSI. Turn on the water fully and check for leaks at all connection points. Before connecting to the pressure washer, run the water for a minute to flush out any debris or sediment that might be in the hose.

Water Temperature Considerations

Most consumer-grade Westinghouse pressure washers are designed for cold water use only. Using hot water can damage internal seals and void your warranty. If you need hot water cleaning capabilities, look for a model specifically rated for warm or hot water operation. Always follow the manufacturer’s specifications regarding maximum water temperature.

Adding Fuel and Checking Oil

For gas-powered Westinghouse pressure washers, proper fuel mixture and oil levels are essential. Use fresh unleaded gasoline with no more than 10% ethanol content. Mix oil according to the manual’s specifications—typically a 50:1 ratio for two-stroke engines. For four-stroke engines, check the oil level using the dipstick and top up with the recommended oil type. Never overfill the crankcase, as excess oil can cause engine damage.

Storing Fuel Properly

Gasoline degrades over time, especially when stored for long periods. Add a fuel stabilizer if you plan to store the washer for more than 30 days. Run the engine until it stops to drain fuel from the carburetor, or use a siphon pump to remove excess fuel before storage. Always store fuel in approved containers away from heat sources and open flames.

Priming the Pump

Many Westinghouse pressure washers come equipped with a priming system to ensure water reaches the pump before startup. To prime the pump, turn on the water supply and open the trigger gun until a steady stream flows freely. Some models have a primer button—press it several times until water appears at the nozzle. This step prevents air locks that could damage the pump during operation.

Starting the Engine

Starting your Westinghouse pressure washer follows a specific sequence to ensure safe and reliable operation:

1. Ensure the water supply is fully open and the trigger gun is in the open position.
2. Set the choke to the proper starting position—usually full choke for cold starts.
3. Turn the ignition switch to the “on” position.
4. Pull the starter cord firmly and smoothly until the engine fires.
5. Once running, gradually move the choke to the “run” position as the engine warms up.
6. Allow the engine to idle for a minute before applying pressure.

Electric Start Models

Some Westinghouse models feature electric start capability. For these units, simply turn the key or press the start button after completing the pre-start checklist. Electric start eliminates the physical effort of pulling a cord but requires access to a power outlet or fully charged battery.

Attaching Nozzles and Hoses

Westinghouse pressure washers typically come with multiple nozzles color-coded for different spray patterns and pressures. The red nozzle delivers the highest pressure for tough stains, while green and white nozzles provide medium pressure for general cleaning. The black nozzle offers the widest fan pattern for rinsing large areas. Always install nozzles by hand-tightening them onto the wand—using tools can damage the threads.

Understanding Spray Patterns

Each nozzle creates a different spray pattern suited to specific tasks:

• Red (0-degree): Concentrated pinpoint spray for removing stubborn stains like rust or paint.
• Yellow (15-degree): Narrow fan pattern ideal for stripping paint or cleaning brick.
• Green (25-degree): Medium fan pattern perfect for general surface cleaning.
• White (40-degree): Wide fan pattern excellent for rinsing soap and delicate surfaces.
• Black (65-degree): Very wide fan pattern for applying detergent or gentle rinsing.

Operating the Pressure Washer

Once the engine is running and warmed up, you can begin operating the pressure washer safely. Hold the wand with both hands and maintain a firm grip. Keep the nozzle perpendicular to the surface you are cleaning and maintain a consistent distance—typically 12 inches for most tasks. Move the wand in smooth, overlapping passes rather than stopping in one spot, which can cause etching or damage to surfaces.

Using Detergent Effectively

Most Westinghouse pressure washers have a detergent injection system. Connect the detergent hose to a container of appropriate cleaner, ensuring the solution matches your cleaning task. Use the low-pressure detergent nozzle (usually black) and apply detergent from bottom to top. Allow the detergent to dwell for 5–10 minutes before rinsing thoroughly with clean water.

Effective Cleaning Techniques

Mastering proper cleaning techniques maximizes efficiency and prevents damage to surfaces. Start with the lowest effective pressure setting and work your way up only if necessary. Always keep the nozzle moving to avoid concentrating pressure in one area. Work systematically across the surface, overlapping each pass slightly. For vertical surfaces like siding, start from the bottom and work upward to prevent streaking.

Surface-Specific Tips

Different materials require different approaches:

• Wood Decks: Use a 40-degree nozzle at moderate distance to avoid splintering the wood grain.
• Concrete Driveways: A 25-degree nozzle works well for general cleaning; use 15-degree for oil stains.
• Vinyl Siding: Stick to 40-degree settings and keep the wand moving to prevent gouging.
• Automotive Paint: Maintain at least 18 inches distance and use wide fan patterns to avoid paint damage.

Proper Shut Down Procedure

Shutting down your pressure washer correctly extends its lifespan and prevents damage. Follow these steps after each use:

1. Turn off the detergent supply and disconnect the detergent hose.
2. Release pressure from the system by squeezing the trigger gun until water stops flowing.
3. Turn off the water supply and disconnect the inlet hose.
4. Shut off the engine and allow it to cool completely before storing.
5. Drain any remaining water from the pump by removing the outlet hose and triggering the gun until dry.
6. Store all components in a dry location away from direct sunlight.
