Usage Features:

Nozzle Selection: The pressure washer comes with five different nozzles for various applications:
- Red: 0° Pencil - Intense cleaning for stubborn stains and dirt on hard surfaces.
- Yellow: 15° Narrow - Heavy cleaning for decks and siding.
- Green: 25° Medium - Standard cleaning for driveways and paint removal.
- White: 40° Wide - Moderate cleaning for autos and boats.
- Black: Detergent - Used with pressure washer detergent for low-pressure application.
Detergent Dispensing: The unit has a detergent tank. Detergent dispensing works only when the spray wand is in the low-pressure position (using the Black nozzle). The pressure washer draws one gallon of detergent for every seven gallons of water.
Starting the Engine: The manual details a manual start procedure involving choke adjustment (START for cold engine, RUN for warm engine), opening the fuel valve, turning on the engine switch, and pulling the starter handle.
Break-in Period: The engine requires a break-in period of approximately 20 hours of use, after which the engine oil should be changed.
Safety Features: Includes a trigger lock on the spray gun to prevent accidental discharge. The engine will shut off if the engine oil level is too low.
High Altitude Operation: For altitudes above 3000 ft, an altitude kit may be required to ensure efficient operation and prevent damage, as the fuel system can be influenced by higher elevations.
Folding and Storing: The handle can be folded forward for compact storage.

Maintenance Features:

Regular Maintenance Schedule: The manual provides a detailed maintenance schedule, including checks for engine oil, air cleaner, sediment cup, spark plug, valve clearance, fuel tank, and carburetor.
Engine Oil Change: Instructions are provided for draining and refilling engine oil, with recommendations for SAE 10W-30 oil and a viscosity grade chart based on outdoor temperature.
Fuel System Maintenance: Emphasizes using fresh, stabilizer-treated unleaded gasoline and cleaning the fuel cap and strainer. Warnings against using gasoline with high ethanol content are prominent.

Air Filter Maintenance: Details on removing, cleaning (for paper and foam filters), and reinstalling the air filter.
Pump Maintenance: The pressure washer pump is described as maintenance-free, but any sign of oil leakage requires professional service.
Long-Term Storage: Comprehensive instructions for preparing the engine and pump for storage longer than 20 days, including cleaning, fuel stabilization, lubrication, and RV antifreeze application for the pump. Regular checks every 3 months during storage are also recommended.
Troubleshooting Guide: A section dedicated to common problems like the engine not starting, misfiring, stopping suddenly, knocking, backfiring, or issues with pressure and detergent intake, along with probable causes and solutions.
Warranty: The emissions control system is warranted by the U.S. Environmental Protection Agency and California Air Resources Board. Warranty information is provided at the end of the manual.
