Karcher HD 7/15 G Professional Petrol Pressure Washer 150 Bar

The Karcher HD 7/15 G is a professional petrol pressure washer. A Honda GX 160 engine drives it. So it needs no mains socket. That suits farms, building sites and any job a long way from power. It sits in Karcher's Petrol Advanced range.

It gives 150 bar of operating pressure. Flow rate is 650 litres per hour. That is plenty for washing vehicles, machinery, walls and hard surfaces. Is it a patio toy? No. It is built for daily trade use.

The frame is heavy duty with puncture-proof tyres. The machine weighs 39.5kg with accessories. A large filter protects the pump. A thermostat valve guards against overheating. It is self-priming too. So it can draw water from a pond or tank. The Easy!Force gun cancels the recoil so your hands stay relaxed. Easy!Lock fittings cut set up time by five times.

Buy it if you need strong cold water cleaning with no cable. The box holds the gun, a 10m hose, an 840mm lance and a power nozzle. Onboard storage keeps the bits together. Karcher Pro covers it with a manufacturer warranty. An optional cage with crane eyelets is sold separately.

Pressure is the force of the jet. Flow is how much water arrives each hour. At 150 bar and 650 l/h this machine cleans fast without being fierce. The Honda GX 160 engine turns the pump. The EasyForce gun uses the jet recoil to cancel the push back, so you hold it with almost no effort. The pump is self-priming. That means it can pull water from a tank or pond. The filter stops grit reaching the pump. The thermostat valve stops it overheating.

Petrol engines need care. Check the oil level before every start. Never run it without oil. Refuel only when the engine is cool and outdoors. Use it in open air only because exhaust fumes are dangerous. Wear eye protection and sturdy boots. Never point the jet at people or animals. Keep the trigger latch on when you put the gun down.
