Karcher HD 9/23 G Professional Petrol Pressure Washer 230 Bar
The Kärcher HD 9/23 G is a professional petrol pressure washer delivering 230 bar of cleaning power, designed for demanding work environments where mains electricity is unavailable. Powered by a reliable Honda GX 390 petrol engine, this cold water high-pressure cleaner operates completely independently, making it ideal for remote sites, agricultural work, and outdoor cleaning applications.
Built for the rigours of professional use, the HD 9/23 G features a robust metal frame that protects critical components whilst maintaining excellent manoeuvrability. The ergonomically designed chassis with puncture-proof wheels ensures smooth transport even across uneven terrain, whilst integrated onboard storage keeps accessories secure and readily accessible throughout the working day.
The machine's self-priming capability allows it to draw water from unpressurised sources such as ponds, lakes or water tanks when mains supply isn't available. A large water filter protects the powerful pump from debris, whilst a thermostat valve prevents overheating during recirculation mode. The full ceramic valve construction extends component lifetime, reducing maintenance requirements and downtime.
Operator comfort is enhanced through the innovative Easy!Force high-pressure gun, which uses the recoil force of the jet to reduce holding effort to zero. Easy!Lock quick-release fasteners make assembly and dismantling five times faster than conventional screw connections, saving valuable time on site. With a flow rate ranging from 400 to 930 litres per hour and adjustable operating pressure from 40 to 230 bar, this versatile unit tackles everything from delicate washing to heavy-duty surface preparation.

Petrol Engines
It is important to read all instructions regarding petrol products. 4 Stroke engines require oil and some machines are supplied dry (No oil to start with). Running a 4 stroke petrol machine without oil will result in the engine seizing and is not covered under warranty.
2 Stroke engines will need to have a mix of oil in the petrol this is normally 1 part oil to 50 parts petrol but not always, again please read the instructions supplied with your machine. Petrol engines do require more maintenance than electric engines but if reguarly maintained they will normally give many years of use.
