Top 3 Frequently Asked Questions
-
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.
-
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.
-
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.
