Karcher HDS 7/10-4 M Professional Hot Water Pressure Washer 100 Bar

The Karcher HDS 7/10-4 M is a single phase hot water pressure washer for professional use. It runs on a normal 230/240V supply. Water heats to between 80 and 155°C from a 12°C feed. That shifts grease and oil in workshops, garages and farm buildings.

Pressure is adjustable from 30 to 100 bar with a 145 bar maximum. Flow runs from 350 to 700 litres per hour. A 3 piston axial pump with ceramic pistons does the pumping. A water-cooled four pole motor drives it. Eco!efficiency mode drops oil use to 3.8kg an hour.

Two detergent tanks with a dosing unit let you swap cleaners fast. Large rubber wheels and a steering roller help you move 182.5kg. An integrated tipping trough helps over obstacles. The EASY!Force Advanced gun has servo control to cut fatigue. A 1050mm stainless steel lance gives reach. Safety valves and water shortage protection guard the machine.

Choose it for busy trade yards that need hot water daily. The 25 litre fuel tank gives long runs. The Soft Damping System takes the shock out of pressure peaks. The set has the gun and a 10m Longlife hose. A hose reel is optional and sold separately.

Hot water washers use a burner to heat the water as it flows. Here the water reaches 80 to 155°C from a 12°C start. Heat softens grease so lower pressure works well. The 3 piston axial pump has ceramic pistons for wear resistance. A water-cooled motor runs cooler in long sessions. The Soft Damping System smooths out pressure peaks and vibration. Eco!efficiency mode uses less heating oil. Safety systems watch for low water and low fuel.

Hot water scalds. Keep the jet away from skin and wear waterproof gloves and eye protection. Use it in a ventilated area because the burner makes exhaust. Check the fuel level and never refuel while it is running. Use a correctly rated 230/240V supply. Lock the trigger when you put the gun down. At 182.5kg the machine needs care on slopes so use the brakes and tipping trough carefully.
