4000psi Petrol Pressure Washer

The HYW4000P is a petrol powered pressure washer powered by the 420cc 4-stroke Hyundai engine, which provides a maximum output of 4000PSI, and a massive flow rate of 15L/min, built for the toughest of cleaning tasks.

This petrol pressure washer model is favoured by cleaning professionals and used in industrial, agricultural and commercial environments. 

Powerful Pressure Washer

The Hyundai 420cc 4 stroke petrol engine has tremendous mid range torque so the jet washer does not have to be operated at maximum revs while cleaning. This makes for a more pleasant, quieter power washing experience and reduces fuel consumption, whilst promoting long engine life.

Fitted with the heavy-duty, Italian Annovi Reverberi (AR) RSV4G40 pump, this Hyundai power washer is designed to be able to handle constant hard work and provide a reliable performance. It also features a thermal relief valve for regulating the temperature and preventing the Annovi Reverberi pump from overheating.

The engine should be filled with 1.1L of SAE30 or 15w40 engine oil. To protect against the engine for added longevity, there is an engine cut out switch which operates if the engine oil is too low.

Portable Pressure Washer

As the largest Hyundai petrol pressure washer, it's also portable and well balanced, mounted on a solid base. Weighing just 61kg, the HYW4000P is easy to transport from one job to the next, which is essential for professional cleaners.

It’s also fitted with tough puncture proof tyres for easy movement across rough terrain, which makes this a truly portable pressure washer.

Petrol Jet Wash

This petrol jet wash's easy pull-start engine makes it especially convenient for use on jobs where no electricity is available.

A 15m hose and lance, 4 nozzles and a turbo nozzle are included as standard and changing the attachments couldn’t be easier due to the quick release fittings and connections.

Gravity Fed or Mains Supply

This Hyundai petrol pressure washer is able to be both gravity fed and fed by a mains supply. It is recommended that the first time the pressure washer is used, it should be connected it to a mains supply to ensure all valves are free moving. After this, it is fine to use with a water butt or drum. It's not supplied with a suction kit, but is able to draw from a barrel.

If drawing uphill from a water butt, we suggest you use the following tips:

• Ensure that the suction hose is 100% sealed against air leaks – any air drawn into the suction side of pump will prevent the machine from priming.
• Connect the pressure washer to a mains water supply and run for 1 minute to free up any sticking valves.
• Position the pressure washer as close to the water supply as possible.
• On startup, to aid priming, prime the pump before connecting the high pressure hose to the pump outlet.
