Top 3 Frequently Asked Questions

1. What type of petrol and oil should I use?

   It uses standard unleaded petrol. For the engine oil, always check the manual, but it typically requires a good quality 15W-40 or similar grade engine oil specifically for 4-stroke petrol engines. Using the wrong oil can void the warranty.

2. Can this pressure washer be used with a water tank (bowser)?

   Yes, this industrial-grade unit is generally capable of drawing water from a static source like a water tank (siphoning). However, you must ensure the tank is positioned above the pump for gravity feed and that the intake filter is clean to prevent damage to the pump.

3. Does the unit include a built-in detergent tank?

   No, this model uses a separate detergent suction hose and the dedicated black soap nozzle.17 When the soap nozzle is attached, the system draws detergent from an external container (like a bottle or bucket) through the hose.18 When you switch to a high-pressure nozzle (coloured tips), the suction stops.
