3. Assembly

Follow these steps to assemble your pressure washer. Refer to the image for visual guidance.

1. Attach the Handle: Slide the upper handle assembly onto the lower frame until the spring buttons lock into place. Secure with provided bolts and knobs if applicable.
2. Install the Wheels: Attach the wheels to the axle using the provided washers and cotter pins.
3. Connect the High-Pressure Hose: Securely attach one end of the high-pressure hose to the pump outlet and the other end to the spray gun. Ensure connections are tight to prevent leaks.
4. Attach the Spray Wand: Thread the spray wand onto the spray gun until it is hand-tight.
5. Insert Nozzles: Select the desired quick-connect nozzle and insert it into the end of the spray wand until it clicks into place.

4. Setup

Before starting the engine, ensure proper fluid levels and connections.

1. Add Engine Oil: Remove the oil fill cap/dipstick and add the provided engine oil until it reaches the 'FULL' mark on the dipstick. Do not overfill.
2. Add Fuel: Fill the fuel tank with fresh, unleaded gasoline (minimum 87 octane). Do not use E85 or mixed fuels. Leave a small space for expansion. Securely replace the fuel cap.
3. Connect Water Supply: Attach a standard garden hose (minimum 5/8 inch diameter) to the water inlet on the pressure washer pump. Ensure the garden hose is free of kinks and has a steady water flow.
4. Purge Air from Pump: With the water supply turned ON, squeeze the trigger on the spray gun to allow water to flow through the pump and hose, expelling any trapped air. Continue until a steady stream of water emerges from the nozzle. This prevents damage to the pump.

5. Operating Instructions

Follow these steps for safe and effective operation of your pressure washer.

Starting the Engine:

1. Ensure the water supply is connected and turned on, and the pump has been purged of air.
2. Set the engine switch to 'ON'.
3. Move the choke lever to the 'FULL CHOKE' position (cold engine) or 'HALF CHOKE' (warm engine).
4. Set the throttle lever to the 'FAST' position.
5. Grip the starter handle firmly and pull the rope slowly until resistance is felt, then pull quickly and smoothly. Repeat until the engine starts.
6. Once the engine starts, gradually move the choke lever to the 'RUN' position.

Using the Pressure Washer:

• Select the appropriate quick-connect nozzle for your task. Different nozzles provide different spray patterns and pressures.
• Hold the spray gun firmly with both hands.
• Maintain a safe distance from the surface being cleaned. Start with a wider spray pattern and move closer as needed.
• Always keep the spray moving to avoid damaging the surface.

Stopping the Engine:

1. Release the spray gun trigger.
2. Turn the engine switch to 'OFF'.
3. Turn off the water supply.
