Regular maintenance is important for keeping a pressure washer in good working condition and prolonging its lifespan. Here are some steps you can take to maintain your pressure washer on an annual basis:
- Change the oil: Check the oil level and change the oil if necessary. Use the recommended oil type for your specific pressure washer model.
- Replace the air filter: A dirty air filter can reduce the performance of the engine and cause it to overheat. Replace the air filter with a new one.
- Clean the spark plug: Use a wire brush to clean the spark plug and make sure it’s tight in the socket.
- Check the hoses: Inspect the hoses for any signs of wear or damage, such as cracks or leaks. Replace any damaged hoses.
- Check the nozzle: Clean or replace the nozzle if it is clogged or worn.
- Check the pump: Inspect the pump for any leaks or damage. If the pump is damaged, it should be replaced (more common will residential-grade aluminum pumps or pumps left to freeze over winter).
- Check the unloader valve: The unloader valve regulates the water pressure. Make sure it’s working properly.
- Check the spray gun: Inspect the spray gun for any damage, and make sure the trigger and safety lock function properly.
- Check the electrical connections: Make sure all electrical connections are tight and secure, and check for any frayed or damaged wires.
- Winterize: If you live in an area with cold winters, it’s important to winterize your pressure washer to prevent freezing and damage (pink RV anti-freeze found at local hardware). This can include draining the water from the pump and hoses and adding a winterizing solution to the pump to protect it from freezing.
It’s important to consult the manual of the specific pressure washer you own to check the specific instructions and precautions. Many manuals will contain maintenance schedules you can easily follow. Always wear protective gear while doing any type of maintenance.
