This powerful and efficient machine is designed for heavy-duty cleaning tasks, utilizing both gas power and a propane burner to deliver hot water for superior cleaning performance. This manual provides essential information for the safe and effective operation, maintenance, and troubleshooting of your pressure washer. Please read this manual thoroughly before operating the unit and keep it for future reference.
Safety Information
Operating a pressure washer requires adherence to strict safety guidelines to prevent injury or damage. Always wear appropriate personal protective equipment (PPE), including eye protection, hearing protection, and sturdy footwear. Never point the spray gun at people, animals, or electrical outlets. Ensure the work area is clear of obstructions and well-ventilated, especially when operating the propane burner. Disconnect the spark plug wire before performing any maintenance. Keep children and pets away from the operating unit.
Setup
Before first use, ensure all components are present and undamaged. Refer to the packing list provided with your unit. Assembly is required for certain parts.
1. Unpacking and Assembly
Carefully remove all components from the packaging. Attach the wheels, handle, and any other accessories as per the assembly diagrams in your quick start guide. Ensure all bolts and fasteners are securely tightened.

2. Connecting Water Supply
Connect a garden hose (minimum 5/8 inch diameter) to the water inlet on the pressure washer pump. Ensure the water source provides sufficient flow (at least 4 GPM) and pressure. Use a clean water source to prevent damage to the pump. Turn on the water supply fully before starting the engine to purge air from the system.
3. Connecting Propane Tank
Place a standard 20 lb (or larger) propane tank onto the designated platform on the pressure washer. Connect the propane hose from the burner unit to the propane tank valve. Ensure all connections are tight and check for leaks using a soapy water solution before operation.

4. Adding Engine Oil and Fuel
Fill the engine crankcase with the recommended type and amount of engine oil (refer to the engine manual for specifics). Fill the fuel tank with fresh, unleaded gasoline. Do not overfill. Always use a fuel stabilizer if storing the unit for extended periods.
Operating Instructions
Follow these steps for safe and effective operation of your pressure washer.
1. Starting the Engine
- Ensure the water supply is fully open and the garden hose is connected.
- Squeeze the spray gun trigger to purge air from the pump and high-pressure hose until a steady stream of water emerges.
- Set the engine switch to 'ON'.
- Open the fuel valve.
- Apply choke if the engine is cold.
- Pull the recoil starter handle firmly until the engine starts. Once started, gradually open the choke.
2. Using the Hot Water Function
The propane burner heats water up to 150°F for enhanced cleaning of grease and grime.

Maintenance
Regular maintenance is crucial for the longevity and optimal performance of your pressure washer.
