Engine Oil Filling & Checking
Maintaining the correct engine oil level is vital for longevity․ Before initial use, and regularly thereafter, check the oil level using the dipstick․ Ensure the pressure washer is on a level surface․ Add oil as needed, using the manufacturer’s recommended type – typically SAE 30․
Do not overfill․ Overfilling can cause engine damage․ Always wipe the dipstick clean before reinserting it for an accurate reading․ Regularly check the oil level, especially before extended use․ Proper oil maintenance ensures smooth engine operation and prevents premature wear․

Operation & Maintenance
Proper use and care extend your pressure washer’s life․ This section details starting, spraying techniques, cleaning, and winterizing procedures for optimal performance․
Starting & Stopping the Engine
Before starting, ensure the unit is on a level surface and the water supply is connected․ Check the engine oil level – maintaining proper lubrication is crucial․ Turn the fuel valve to the ‘ON’ position and, if equipped, set the choke․
To start, pull the starter cord firmly and steadily․ Avoid rapid, jerky pulls․ Once the engine starts, gradually adjust the choke for smooth operation․ To stop, turn the fuel valve to the ‘OFF’ position․
Allow the engine to cool before refueling․ Never attempt to start or run the pressure washer indoors or in poorly ventilated areas․ Regular engine maintenance, as outlined in the Simpson engine manual, is essential for reliable performance and longevity․
Proper Spraying Techniques
Always begin with a wider nozzle (lower pressure) and test on an inconspicuous area․ Maintain a consistent distance from the surface – typically 8-12 inches – for even cleaning․ Use sweeping motions, overlapping each pass slightly to avoid streaking․
For stubborn dirt, gradually increase pressure by switching to a narrower nozzle․ Avoid directing the spray at electrical outlets, windows, or delicate surfaces․ When using detergents, follow the manufacturer’s instructions and utilize the detergent injection system correctly․
Remember safety glasses are crucial․ Proper technique maximizes cleaning efficiency and minimizes potential damage to surfaces․
Cleaning & Flushing the System
After each use, disconnect the water supply and trigger the gun to relieve remaining pressure․ Flush the pump with clean water by running the pressure washer for a short period with only water flowing through it․ This removes detergent residue and prevents corrosion․
Inspect the nozzles for clogs and clean them as needed․ Wipe down the exterior of the pressure washer with a damp cloth․ Store the unit in a dry, protected area, preventing freezing temperatures․
Regular flushing extends the life of your Simpson pressure washer․
Winterizing Your Pressure Washer
Before storing your Simpson pressure washer for winter, thoroughly drain all water from the pump, hose, and wand․ Use a pump saver kit, adding antifreeze to protect internal components from freezing damage․ Disconnect and store the hose in a frost-free location․
Empty any remaining detergent from the tank and run the engine briefly to clear the lines․ Change the engine oil according to the Simpson engine manual’s recommendations․ Store the unit indoors, covered, to shield it from the elements․

Troubleshooting Common Issues
This section addresses frequent problems like engine failure, low pressure, leaks, and pump pulsation, offering solutions for optimal performance and longevity․
Engine Won’t Start
If the engine fails to start, first verify the fuel level and ensure fresh gasoline is present․ Check the spark plug for fouling or damage, replacing it if necessary․ Confirm the engine switch is in the ‘on’ position and the choke is appropriately set for cold starts – typically fully engaged initially, then gradually reduced as the engine warms․
Inspect the air filter for obstructions, cleaning or replacing it as needed to ensure proper airflow․ A clogged air filter restricts combustion․ Also, examine the fuel line for kinks or blockages preventing fuel delivery․ If equipped, test the safety switch functionality; ensure it’s properly engaged․ Finally, a low oil level can trigger a safety shutdown – verify and top up if required․
Low Pressure Output
Reduced pressure often stems from a partially clogged nozzle; remove and thoroughly clean all nozzles with a nozzle cleaning tool․ Inspect the high-pressure hose for kinks, cuts, or damage, as these restrict water flow․ Verify the water supply is fully open and provides adequate volume – a restricted inlet diminishes output․
Check the pump inlet filter for debris, cleaning it to ensure unrestricted water intake․ A worn or damaged pump can also cause low pressure, potentially requiring professional repair or replacement․ Ensure the pressure regulator (if equipped) isn’t set too low․ Finally, air in the system can reduce pressure; trigger the gun to bleed out any trapped air․
Leaking Water
Water leaks commonly originate from hose connections; ensure all connections are tight and the quick-connect fittings are properly seated․ Inspect the high-pressure hose itself for cracks or damage, replacing it if necessary․ Check the pump connections for tightness, but avoid over-tightening, which can damage the pump․
Examine the spray gun and wand for leaks around the trigger or handle, potentially requiring O-ring replacement․ A leaking pump seal indicates internal pump damage, necessitating professional repair․ Verify the garden hose connection to the pressure washer is secure and free of leaks․ Finally, ensure proper winterization prevents freezing and subsequent cracking․
Pump Pulsation
Noticeable pump pulsation, an uneven spray, often indicates air entering the pump system․ This can stem from loose inlet connections on the water supply hose, requiring tightening․ Check the inlet filter for debris blockage, cleaning or replacing it as needed․ A worn or damaged pump valve can also cause pulsation, necessitating professional pump repair or replacement․
Low water supply pressure contributes to pulsation; ensure adequate water flow to the pressure washer․ Inspect the pump’s unloader valve for proper function, as a faulty valve can induce pulsing․ Consistent pulsation despite these checks suggests internal pump wear, demanding expert attention․
