2. Safety Information
Always prioritize safety when operating the pressure washer. Failure to follow these instructions could result in serious injury or property damage.
- Read the Manual: Read and understand all instructions before operating the unit.
- Personal Protective Equipment (PPE): Always wear appropriate eye protection (safety glasses or goggles), hearing protection, and protective footwear (e.g., rubber boots) during operation.
- Fuel Safety:
- Use fresh, clean gasoline.
- Never refuel a hot or running engine. Allow the engine to cool before adding fuel.
- Refuel in a well-ventilated area, away from sparks or open flames.
- Do not overfill the fuel tank.
- Engine Safety:
- Operate the pressure washer in a well-ventilated outdoor area to avoid carbon monoxide poisoning.
- Keep hands, feet, and clothing away from moving parts.
- Ensure the engine is off and cooled before performing any maintenance.
- High-Pressure Safety:
- Never point the spray gun at people, pets, or electrical outlets.
- Maintain a firm grip on the spray gun, as the high-pressure spray can cause kickback.
- Do not operate the unit if the hose or connections are damaged.
- Always engage the trigger safety lock when the spray gun is not in use.
- Stability: Ensure the pressure washer is on a stable, level surface during operation to prevent tipping.
- Children and Pets: Keep children and pets away from the operating area.
3. Components and Parts
Your TEANDE Gas Pressure Washer comes with several key components for assembly and operation:
- Main Unit: Engine, pump, and frame with 8-inch wheels.
- High-Pressure Hose: 25-foot flexible, kink, and abrasion-resistant hose.
- Spray Gun: Ergonomic design for comfortable use.
- Quick-Connect Nozzles: 5 different nozzles for various spray patterns (0°, 25°, 40°, 75°, and soap nozzle).
- Foam Bottle: For applying detergent.


4. Setup
Follow these steps to set up your pressure washer for first use:
- Attach Wheels and Handle: The unit comes mostly assembled. Attach the 8-inch wheels to the axle and secure them. Then, attach the portable non-slip handle to the main frame.
- Add Engine Oil:
Before first use, ensure the engine oil reservoir is filled to the appropriate level. Use a funnel to carefully pour the recommended engine oil (refer to the engine manual for specific oil type and capacity) into the oil fill port. Do not overfill.

- Add Fuel:
Fill the fuel tank with fresh, clean gasoline. Refer to the engine manual for the correct fuel type (typically unleaded gasoline). Do not overfill and ensure the fuel cap is securely tightened.

- Connect Inlet and Outlet Pipes:
Connect your garden hose to the pressure washer's water inlet. Ensure the connection is tight to prevent leaks. Then, connect the high-pressure hose to the pump's high-pressure outlet and to the spray gun.

- Attach Detergent Tank (Optional): If using detergent, attach the foam bottle to the designated inlet.
5. Operating the Pressure Washer
Follow these steps for safe and effective operation:
- Start the Engine:
Turn the engine switch to the "ON" position. Locate the choke lever and move it to the "CLOSED" position for a cold start. Pull the start rope firmly until the engine starts. Once the engine is running, gradually move the choke lever to the "OPEN" position.

- Nozzle Selection:
Choose the appropriate quick-connect nozzle for your cleaning task. The 0° (red) nozzle provides a concentrated, powerful stream for tough stains. The 25° (green) nozzle is for general cleaning of hard surfaces. The 40° (white) nozzle is ideal for delicate surfaces like wood or vehicles. The 75° (black) nozzle is a low-pressure nozzle for applying soap. The foam bottle can be used with the black nozzle for detergent application.

- Cleaning Techniques:
Always test the spray on an inconspicuous area first. Hold the spray gun at a consistent distance from the surface, typically 6-12 inches, and use sweeping motions. For stubborn dirt, you may need to get closer, but be cautious not to damage the surface. For large flat areas like driveways, consider using a surface cleaner attachment (sold separately) for more even and efficient cleaning.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your pressure washer. Always disconnect the spark plug wire and allow the engine to cool before performing any maintenance.
- Engine Oil: Check engine oil level before each use. Change oil after the first 5 hours of operation, then every 50 hours or annually, whichever comes first.
- Air Filter: Inspect the air filter regularly and clean or replace it if it's dirty. A clogged air filter can reduce engine performance.
- Spark Plug: Inspect the spark plug annually or every 100 hours. Clean or replace if necessary.
- Fuel System: Drain the fuel tank and carburetor if storing the unit for more than 30 days to prevent fuel degradation. Use a fuel stabilizer if storing with fuel.
- Pump Care:
- Winterization: If storing in freezing temperatures, use a pump protector or RV antifreeze to prevent damage to the pump.
- Storage: Store the pressure washer in a dry, protected area.
- Hose and Nozzles: Inspect the high-pressure hose for kinks, cuts, or leaks before each use. Clean nozzles regularly to prevent clogs.
7. Troubleshooting
If you encounter issues with your pressure washer, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Engine will not start | No fuel or low oil level | Fill fuel tank, check and add oil. |
| Choke in wrong position | Adjust choke lever (closed for cold, open for warm). | |
| Spark plug fouled or loose | Clean or replace spark plug; ensure it's tight. | |
| Low or no pressure | Clogged nozzle | Clean the nozzle with the provided cleaning tool. |
| Kinked or blocked garden hose | Straighten hose or remove obstruction. | |
