What Maintenance Tips Can Help Extend the Life of Your Simpson Pressure Washer?

To extend the life of your Simpson pressure washer, perform regular maintenance and follow key care tips.

  1. Regular oil changes
  2. Clean or replace air filters
  3. Winterize the unit in colder months
  4. Inspect hoses and connections
  5. Use appropriate fuel
  6. Clean the spray nozzle
  7. Check the spark plug
  8. Maintain proper pump oil levels

Regular maintenance ensures optimal performance.

  1. Regular Oil Changes: Regular oil changes are crucial for maintaining a pressure washer’s engine. Engine oil lubricates moving parts, reducing friction and preventing wear. Simpson recommends changing the oil after the first 5 hours of use and every 50 hours thereafter. Using the right oil type, such as SAE 30 for warm conditions or synthetic oil for colder climates, enhances engine life.

  2. Clean or Replace Air Filters: Cleaning or replacing air filters allows for better airflow to the engine, which optimizes combustion. A dirty filter can restrict airflow, leading to decreased performance. Simpson suggests inspecting the air filter after every 10 hours of operation and replacing it as needed to maintain efficiency.

  3. Winterize the Unit in Colder Months: Winterizing your pressure washer prevents damage from freezing temperatures. This involves draining water from the unit and storing it in a warm environment. Simpson offers a winterizing kit that includes antifreeze options to further protect the pump and components from frost damage.

  4. Inspect Hoses and Connections: Regular inspection of hoses and connections for leaks or wear is important for safety and efficiency. Simpson advises checking hoses before each use, as damaged hoses can lead to decreased pressure and performance.

  5. Use Appropriate Fuel: Using the right fuel, such as unleaded gasoline with an octane rating of 87 or higher, prevents engine issues. Simpson also recommends avoiding fuel with more than 10% ethanol, as it can damage small engines. Proper fuel management extends engine life and ensures reliability.

  6. Clean the Spray Nozzle: Keeping the spray nozzle clean allows for proper water flow and pressure. Clogs can reduce performance and cause strain on the unit. Simpson recommends cleaning the nozzle with a warm, soapy solution or using a nozzle cleaning tool to clear any blockages.

  7. Check the Spark Plug: Regularly checking the spark plug ensures proper ignition and engine operation. Simpson suggests inspecting and cleaning the spark plug every 50 hours of use and replacing it if the electrode is worn. A well-maintained spark plug contributes to smooth engine performance.

  8. Maintain Proper Pump Oil Levels: Proper pump oil levels lubricate the pump, ensuring it operates correctly and efficiently. Simpson recommends checking the pump oil level before each use and changing the oil after the first 50 hours of operation. Using the correct type of pump oil is vital to prevent pump failure.
