Karcher HD 6/15 G Classic Professional Petrol Pressure Washer 150 Bar

The Karcher HD 6/15 G Classic is the entry model in the Karcher Professional cold water petrol range. It is made for outdoor work where mains power is hard to find. Builders, farmers and council cleaning teams are the target users.

Working pressure is 150 bar. Maximum pressure is 200 bar. Flow reaches 600 litres an hour. That is enough to strip dried mud and dirt from plant and yards. A power nozzle is supplied for the job.

A G200FA petrol engine starts with a manual pull. The crankshaft pump has ceramic pistons. A thermostat valve protects it from overheating in recirculation mode. You get a 10m hose and a standard trigger gun. The machine needs a water feed of at least 1 bar. It cannot draw from unpressurised tanks.

The steel frame is tubular and tough. Pneumatic tyres and a push handle make it easy to wheel across site. Hose hooks and holders give tidy built-in storage. At 42.5kg with accessories it is heavy but still fits in a standard car. Karcher guarantees it for commercial use.

A crankshaft pump with ceramic pistons is a step up from the axial pumps in home washers. It copes better with long daily use. Working pressure of 150 bar and 600 litres an hour clears heavy dirt. The peak of 200 bar is brief. In recirculation mode the water heats up. The thermostat valve opens to dump hot water and protect the pump. Always connect a mains water feed.

Use outdoors only as petrol engines give off exhaust fumes. Check engine oil before starting. Let the engine cool before refuelling. Connect a water supply before you start the engine. Never run the pump dry. Never aim the jet at people. Wear ear and eye protection. Lift with help as the unit weighs 42.5kg.
