Fuel and Oil
Before starting, ensure the engine has sufficient oil and fuel. Use fresh, unleaded gasoline and the recommended engine oil type as specified in your product manual. The unit features a large fuel tank for extended cleaning time between refills.
Connecting Hoses

Troubleshooting
If you encounter issues with your pressure washer, refer to these common troubleshooting tips:
