Safety Precautions
Always prioritize safety when operating this pressure washer. Wear safety glasses to protect your eyes from debris. Avoid directing the high-pressure spray at people, animals, or electrical connections. Never modify the pressure washer or use incompatible parts. Ensure proper ventilation when operating the engine, and disconnect the spark plug before maintenance.
General Safety Guidelines
Read the entire manual before using the Simpson 3100 PSI pressure washer. Understand all controls and safety features. Keep children and bystanders away from the operating area. Never leave the machine unattended while running. Wear appropriate clothing, including closed-toe shoes, and avoid loose garments. Inspect the equipment before each use.
High-Pressure Spray Safety
Never point the wand at yourself or others. The high-pressure spray can cause serious injury. Avoid spraying electrical components or outlets. Do not attempt to modify the gun or wand. Always release pressure before disconnecting hoses or nozzles. Be mindful of the spray’s recoil force and maintain a firm grip.
Component Identification
The Simpson 3100 PSI unit features a robust engine, high-pressure pump, and durable spray gun. Key components include various quick-connect nozzles, a high-pressure hose, and a detergent tank. Familiarize yourself with the throttle, choke, and on/off switch locations for safe and efficient operation. Understanding each part is crucial.

Nozzle Selection and Usage
Simpson pressure washers utilize quick-connect nozzles, each delivering a different spray pattern. A 0° nozzle provides a concentrated stream for tough stains, while a 40° nozzle offers a wider fan for general cleaning. Always select the appropriate nozzle for the task to avoid damage. Test in an inconspicuous area first!

Hose and Wand Assembly
Proper hose and wand connection is crucial for safe operation. Ensure the high-pressure hose is securely attached to both the pump and the spray gun. The wand then connects to the spray gun, utilizing a quick-connect mechanism. Verify all connections are tight before starting the engine to prevent leaks and potential injury.
Assembly Instructions
Before initial use, careful assembly is required. This includes attaching the high-pressure hose to the pump outlet, ensuring a secure and leak-proof connection. Next, connect the spray wand to the trigger gun, again verifying a firm fit. Finally, select and attach the desired nozzle to the wand, readying the unit for operation.
Attaching the Hose to the Pump
Securely connect the high-pressure hose to the pump outlet, hand-tightening initially. Then, use a wrench to tighten further, ensuring a watertight seal. Avoid over-tightening, which could damage the fittings. Inspect the connection for any leaks before operation; a loose connection can cause pressure loss and potential injury.

Connecting the Wand and Nozzle
Attach the desired nozzle to the spray wand, ensuring it clicks securely into place. Then, connect the wand to the trigger gun, again verifying a firm connection. Always select the appropriate nozzle for the cleaning task to avoid damage. Never attempt to modify or bypass safety features during nozzle installation.
Operating Instructions
Before starting, ensure all connections are secure and the unit has sufficient oil. Begin by turning on the water supply, then pull the starter cord to ignite the engine. Adjust the throttle for desired pressure, referencing the manual for specific nozzle settings. Always maintain a safe distance from surfaces during operation.
Starting the Engine
Ensure the fuel valve is open and the choke is set to the ‘start’ position. Gently pull the starter cord until resistance is felt, then pull briskly. Repeat if necessary, adjusting the choke as the engine warms. Once running, gradually reduce choke and adjust throttle for optimal performance. Refer to the manual for detailed guidance.
Adjusting Pressure Settings
Utilize the unloader valve to regulate pressure, starting with a lower setting for delicate surfaces. Gradually increase pressure as needed, testing on an inconspicuous area first. Different nozzles also affect pressure; wider nozzles deliver lower pressure. Always prioritize safety and consult the manual for specific nozzle recommendations and pressure guidelines.

Maintenance and Care
Regular maintenance ensures longevity. Clean nozzles after each use to prevent clogging, and inspect the hose for damage. Perform oil changes according to the schedule in the manual – typically after every 50 hours of operation. Store the unit in a dry place, protecting it from freezing temperatures to avoid component damage.
Cleaning the Nozzles

Clogged nozzles reduce performance. Remove nozzles and soak them in a nozzle cleaning solution or white vinegar overnight. Use a small wire or pin to gently clear any remaining debris from the nozzle orifice. Always inspect for wear and replace damaged nozzles promptly to maintain optimal spray patterns and pressure.

Oil Change Procedures
Regular oil changes are crucial for engine longevity. Drain the old oil while the engine is warm, but not hot. Replace the oil filter with a new one, and refill with the recommended oil type (check your manual). Dispose of used oil responsibly at a recycling center. Maintain proper oil levels for peak performance.
Troubleshooting Common Issues
Addressing problems promptly ensures continued operation. If the engine won’t start, check fuel levels, spark plug, and air filter. For pressure loss, inspect the nozzle for clogs, verify hose connections, and ensure adequate water supply. Consult the manual for detailed diagnostics and solutions to common malfunctions.
Engine Won’t Start
A non-starting engine requires systematic checks. First, verify sufficient fuel and a clean air filter. Inspect the spark plug for fouling or damage, replacing if necessary. Ensure the choke is properly positioned. If issues persist, consult the Simpson manual for specific troubleshooting steps related to the engine’s starting mechanism.
Pressure Loss Problems
Reduced pressure often indicates a blockage. Check the nozzle for clogs and clean thoroughly. Inspect the high-pressure hose for kinks or damage, and verify proper connections. A worn pump or faulty unloader valve can also cause pressure loss; consult the Simpson manual for detailed diagnostics and potential repair solutions.
