Karcher HD 9/25 G Classic Professional Petrol Pressure Washer 250 Bar
The Kärcher HD 9/25 G Classic is a professional petrol pressure washer delivering 250 bar working pressure for demanding cold water cleaning applications. As the most powerful machine in the Kärcher Classic petrol range, this unit combines a robust crankshaft pump with ceramic pistons and a 900 litres per hour flow rate to tackle heavy-duty cleaning tasks on construction sites, agricultural facilities, and other challenging environments where mains electricity isn't available.
Powered by an EU STAGE V compliant petrol engine with manual pull start, the HD 9/25 G Classic eliminates dependence on external power supplies whilst meeting current emissions standards. The machine features a robust tubular steel frame for protection against accidental impacts, complemented by puncture-proof wheels that provide reliable mobility across rough terrain. At just 56.8kg and with compact dimensions of 878 x 538 x 702mm, the unit fits easily in small vehicles and includes an ergonomic push handle for comfortable manoeuvring.
Practical design features include integrated accessory storage and a hose hook for tidy transport, whilst important components remain easily accessible for routine servicing. Machine protection is provided through thermo and safety valves, alongside a large water filter. The unit's maximum pressure capability extends to 300 bar when required for particularly stubborn cleaning challenges.
Please Note: This machine requires a pressurised water feed of at least 1 bar and is not designed to draw water from unpressurised sources such as water tanks.

Petrol Engines
It is important to read all instructions regarding petrol products. 4 Stroke engines require oil and some machines are supplied dry (No oil to start with). Running a 4 stroke petrol machine without oil will result in the engine seizing and is not covered under warranty.
2 Stroke engines will need to have a mix of oil in the petrol this is normally 1 part oil to 50 parts petrol but not always, again please read the instructions supplied with your machine. Petrol engines do require more maintenance than electric engines but if reguarly maintained they will normally give many years of use.
Pressure Washer Help
To help determine the type of pressure washer required it is important to consider the size of your cleaning task and level of duty, i.e. how big is the cleaning object and how often will you need to clean it? Below is an explanation of the two main types of pressure washer. Whilst bar pressure is important the overriding factor in cleaning power is the water flow rate. More water = better cleaning.
Jargon Buster:
• Bar or PSI: Bar is the most common measure of pressure. PSI = bar x 14.5.
• Bar (max): This is the pressure achieved when the machine is first turned on
• Bar (rated) pressure: This is the operating water pressure of the machine.
• Motor size (kW): Motor size indicates power providing the machine runs efficiently.
• Flow Rate (l/h): Higher flow rates enable you to clean large areas or objects faster
Did You Know:
Pressure Washers use up to 80% less water than garden hosepipes.
Pressure Washers are not subject to hosepipe bans if used for safety reasons, or if a suction hose is used to pull water from a harvested source. i.e. not the water mains. They are also not subject to a ban if used for commercial reasons, for example to maintain cleanliness, hygiene or company image.
Important things to remember when using your pressure washer:
• Always use an RCD when using electrical products in connection with water.
• Never use a non-return valve at the pressure washer connection to a hose pipe.
• Never drive over or lay items on high pressure hoses to avoid damage.
• Your water supply hose should be a min of several meters long and unwound from its reel.
• If you are using an extension lead, check that it is rated at min of 13 amps and fully unwound from its reel.
