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.

    Amazing machine

    Posted by Jamie on 22nd Apr 2024

    Brought this as as a replacement to my trusty Honda gx200pressure washer and I can honestly say this is so much better. The power is amazing and the stylish looks really top off this machine. Delivery was prompt and set up was simple. The engine is supplied dry with no oil but the pump comes already filled with pump oil so make sure you have the correct engine oil to hand. The turbo nozzle makes light work of moss and stubborn grime. Highly recommend this machine for the price *****

    Pressure washer 4000psi

    Posted by Mark Byrne on 8th Aug 2022

    I agonised over buying this for weeks, but glad I finally did. The power is immense, and when teamed up with the whirlaway cuts work time by half. The machine arrived promptly and was easy to set up, but please maybe include some oil as I had to wait another day to get some !

    Excellent piece of equipment. I searched the inter net looking for the right machine at an affordable price. Honda is the first brand that pops in to your head but at £1250 for an equivalent machine I thought I would have a go at this beast. My god it's good, I have been blown away with the results. Excellent piece of equipment

    A beast

    Posted by Rm Nairn on 9th Jan 2020

    Just purchased one of these end of the year, what a power, my original pump from unionmarts ltd was supposedly 4800 psi the tx850, falls to bits and breaks down all the time, this pump is pure quality and is a little bit pricey, but the power more than make up for that, Customer service is first class and with a 3 year warranty what more can I first try out was near a phone box accross from my house with the pavement looking real dirty, the ideal testing area, shame I couldn’t upload a video to show the power
