The device is a professional high-pressure hot washer, specifically the Clarke KING 200 model (Part No: 7320176). It is designed to clean surfaces using hot or cold water, leveraging the force of a high-pressure water jet and the action of detergents.
Function Description:
The Clarke KING 200 is a versatile pressure washer capable of delivering both hot and cold water for cleaning tasks. Its primary function is to remove dirt, grime, and other contaminants from various surfaces that can withstand high-pressure water and detergents. The machine incorporates an Automatic Stop System, which stops the machine during bypass mode and restarts it automatically when the trigger is pulled. This system enhances energy efficiency and prolongs the life of the pump. The hot wash feature is particularly useful for tackling stubborn grease and oil, offering a more effective cleaning solution than cold water alone.

Usage Features:
The Clarke KING 200 offers several features for ease of use and safety:
- Controls: It includes an On/off Switch for the main power, a Burner On/Off Switch for hot water operation, and a Burner Thermostat to adjust the desired water temperature. A pressure gauge is also integrated for monitoring.
- Spray Pattern Adjustment: The nozzle allows for adjustment between a pencil jet and a fan spray by turning it counter-clockwise through a half-a-turn (180°). This versatility enables users to choose the appropriate spray for different cleaning tasks.
- Pressure Adjustment: Users can adjust the pressure by varying the distance from the surface being cleaned or by adjusting the spray to a wider angle, which lowers the pressure.
- Detergent Application: The machine has a dedicated detergent tank (2.5 litres capacity) for applying cleaning agents. Only approved detergents, such as CLARKE Traffic Film Remover or CLARKE Wash and Wax, should be used.
- Gun Assembly Safety Lock: A safety button on the gun prevents accidental operation of the trigger. The locking lever can be lifted to prevent the trigger from being pulled and folded flat to release it.
- Automatic Stop System: This system automatically stops the machine when the trigger is released (bypass mode) and restarts it when the trigger is pulled, contributing to energy saving and reduced wear. If the machine is not used for more than 5 minutes, it is recommended to set the ON/OFF switch to OFF.
- Fueling: The diesel tank has a capacity of 14 litres, with a minimum fill of 4 litres. Refueling must be done in a well-ventilated area, away from ignition sources, and spillages should be avoided.
- Water Supply: The pressure washer must be connected to a drinking water supply via a system separator (backflow preventer) to comply with local water company regulations. The water supply should deliver at least 10 l/min with an inlet temperature between 5°C and 40°C.
- Hose Connections: The high-pressure hose connects to the machine's outlet and the gun assembly, secured by hand-tightened connectors. The extension lance attaches to the gun assembly.
Maintenance Features:
Regular maintenance is crucial for the longevity and optimal performance of the Clarke KING 200:
- Safety First: Always disconnect the machine from the power source during cleaning or maintenance. Avoid spraying the machine with water or using aggressive solvents, as these can cause damage.
- Exterior Cleaning: The exterior of the machine should be cleaned with a dry cloth.
- Water Inlet Filter Cleaning: The water inlet filter should be checked and cleaned frequently to ensure the pump operates efficiently. This involves rinsing the nozzle, hose connection, and water filter under running water.
- Nozzle Cleaning: A blocked nozzle can impair performance. To clean it, switch off the machine, remove the lance, clean the nozzle with the provided pin, and then rinse the lance under running water.
- Fuel System Maintenance: The troubleshooting guide suggests cleaning the fuel filter and emptying/cleaning the diesel tank if impurities or water are present in the fuel, or if there is too much smoke from the exhaust.
- General Checks: Regular checks for worn-out valves, seals, or a clogged boiler coil (due to limestone) are recommended, with contact to CLARKE service for such issues.
The device is supplied with a pressure washer unit, gun assembly, lance assembly, water inlet hose adaptor, hose assembly, and a high-pressure nozzle. It is important to read the manual thoroughly before use to ensure safety and proper operation. Electrical connections require adherence to specific wiring codes and the use of a BS1363/A approved plug with a 13 Amp fuse. The use of a Residual Current Device (RCD) is strongly recommended for mains supply connection.
