Choke and Throttle Operation
The choke controls the air-fuel mixture for starting a cold engine. When set to ‘FULL’, it restricts airflow, enriching the mixture for easier ignition. Gradually move it to ‘RUN’ as the engine warms.
The throttle regulates engine speed and power. Increasing the throttle increases engine RPMs and water pressure. Locate the throttle trigger on top of the unit, near the choke. Use it to adjust performance based on the cleaning task.
Proper choke and throttle adjustment is vital for smooth starting and efficient operation. Refer to the full manual for detailed guidance and safety precautions regarding these controls.
Starting Procedure – Cold Engine
Ensure the pressure washer is on a level surface with the water supply connected. Turn the fuel valve to the ‘ON’ position. Set the choke to ‘FULL’. Slowly pull the starter cord until resistance is felt, then pull briskly. Repeat if necessary, but avoid continuous pulling.
Once the engine starts, gradually move the choke to the ‘RUN’ position as it warms up. Adjust the throttle to control engine speed. Allow the engine to run for a few minutes to stabilize before engaging the spray gun.
Always follow safety guidelines and consult the complete manual for detailed instructions and troubleshooting tips.
Starting Procedure – Warm Engine
If the engine is warm, the starting procedure is simplified. Ensure the fuel valve is in the ‘ON’ position. The choke may not be necessary; attempt to start the engine without engaging it initially. Slowly pull the starter cord until resistance is felt, then pull with a firm, brisk motion.
If the engine doesn’t start, engage the choke partially and repeat the starting process. Adjust the throttle as needed to maintain a stable idle. Allow the engine to warm up briefly before using the pressure washer.
Refer to the full manual for comprehensive safety instructions and detailed troubleshooting guidance.
Adjusting Pressure Settings
The Simpson 3100 PSI pressure washer allows for adjustable pressure settings to suit various cleaning tasks. Locate the pressure adjustment knob, typically found near the trigger gun or pump. Turning the knob clockwise increases the pressure, while turning it counterclockwise decreases it.
Start with the lowest pressure setting and gradually increase it until the desired cleaning power is achieved. Always test the pressure on an inconspicuous area first to avoid damage. Be mindful of the surface you are cleaning and select an appropriate pressure level.
Refer to the nozzle guide for recommended pressure settings for different applications.
Using Different Nozzles
Your Simpson 3100 PSI pressure washer includes multiple nozzles for diverse cleaning needs. The 0-degree nozzle delivers a concentrated, powerful stream ideal for stubborn dirt and small areas, use with caution.

It’s excellent for general cleaning tasks around the home, including washing decks, patios, siding, and outdoor furniture. This nozzle effectively removes dirt, mildew, and algae without causing excessive damage.
It’s a safe choice for most surfaces, but testing in an unseen area is still recommended. Maintain a consistent distance for even cleaning. The 25-degree nozzle is a great all-purpose option for routine maintenance and revitalizing exterior surfaces, providing effective results with minimal risk.
40-Degree Nozzle Applications
The 40-degree nozzle delivers a wider, lower-pressure spray pattern, making it ideal for delicate cleaning tasks with your Simpson 3100 PSI pressure washer. This nozzle is perfect for washing cars, boats, and other vehicles, as it minimizes the risk of paint damage. It’s also suitable for cleaning windows, screens, and more sensitive siding materials.
Because of its gentler spray, the 40-degree nozzle is excellent for rinsing away soap and detergents after cleaning. It provides a broad coverage area, reducing cleaning time. Always test on an inconspicuous spot first to ensure compatibility with the surface being cleaned, maximizing safety and effectiveness.
Soap Nozzle Applications
The soap nozzle, typically black in color, is specifically designed for applying detergents and soaps with your Simpson 3100 PSI pressure washer. This nozzle creates a low-pressure, high-volume spray that effectively mixes soap with water for optimal cleaning power. It’s ideal for washing cars, decks, patios, and siding.
Ensure you use detergents specifically formulated for pressure washers to avoid damage to the unit or the surface being cleaned. Adjust the detergent dial on the pressure washer to control the soap-to-water ratio. Always rinse thoroughly after applying soap to prevent residue buildup, ensuring a clean and professional finish.

Maintenance and Troubleshooting

Reinstall the clean filter and close the housing securely.
Nozzle Cleaning and Maintenance
Maintaining clean nozzles ensures optimal spray patterns and pressure. Over time, nozzles can become clogged with mineral deposits or debris. To clean, first disconnect the nozzle from the spray wand. Inspect the nozzle orifice for any obstructions.
Use a nozzle cleaning tool or a thin wire to carefully clear any blockages – avoid enlarging the orifice. For stubborn clogs, soak the nozzle in vinegar or a nozzle cleaner solution. Rinse thoroughly with water before reattaching. Regularly inspect nozzles for wear and tear; damaged nozzles should be replaced to maintain performance and safety.
Troubleshooting Common Issues
Engine Won’t Start: Check fuel levels, ensure the spark plug is clean and properly connected, and verify the choke is in the correct position. Low Pressure Output: Inspect the water supply connection, check for kinks in the hose, and clean the nozzles. A clogged nozzle significantly reduces pressure.

Check the throttle position; it should be set appropriately for starting; If problems continue, consult the full instruction manual for detailed diagrams and troubleshooting steps. Contact Simpson’s customer service at 1-877-362-4271 if needed.
Low Pressure Output
Experiencing low pressure? First, inspect the nozzle for clogs or obstructions and clean it thoroughly. Verify the water supply is fully open and provides adequate volume. Check the high-pressure hose for kinks, damage, or leaks, as these restrict water flow. Ensure the pump is primed correctly, following the instructions in the manual.
Confirm you’ve selected the appropriate nozzle for the task. A partially clogged fuel filter or a malfunctioning pressure regulator can also cause low pressure. If issues persist, consult the manual or contact Simpson’s customer service at 1-877-362-4271.
Leaking Water
Water leaks can originate from several areas. Inspect all hose connections – the water inlet, high-pressure hose to the pump, and nozzle connection – ensuring they are tight and properly secured. Examine the pump itself for any visible cracks or damage. Check the o-rings and seals around these connections; replacement may be necessary;
A leaking nozzle often indicates a worn or damaged seal. If the leak is from the engine area, it could signify a more serious issue requiring professional attention. Always disconnect the power source before inspecting for leaks. Contact Simpson’s customer service at 1-877-362-4271 for assistance.
