This document describes the CLARKE Power Washer, Model No: JET 9500 (Part No: 7333520), an electric-powered pressure washer designed for cleaning various items and surfaces using a high-pressure water jet, with the option of adding cleaning agents.
Function Description:
The CLARKE Power Washer is designed to clean machines, vehicles, buildings, boats, facades, terraces, and gardening tools. It operates by generating a high-pressure water jet, which can be combined with approved cleaning agents for enhanced cleaning performance. The machine features an integral detergent tank for this purpose.

Usage Features:
The pressure washer is designed for user convenience and safety.
- Assembly: The handle pushes into the hose reel until it clicks. Storage brackets slide into position and click. The high-pressure hose unwinds from the reel and connects securely to the gun, requiring tightening with a spanner. The lance then fits to the gun.
- Water Supply Connection: The inlet adaptor screws onto the water inlet. A standard garden hose (or reinforced hose with at least 10 mm inner diameter) connects to the inlet adaptor and then to the water supply. The water supply must provide a minimum of 7 litres per minute at a maximum of 40°C. It is crucial to turn the water supply on fully before operating the machine to prevent damage.
- Operation: After connecting the water supply and plugging the mains power cable into an electrical supply, the ON/OFF switch is set to the ON position. The trigger lock is released, and the machine is ready for use. Users must maintain a firm footing and grip the gun and spray lance firmly, as the spray gun will "kick" upon starting. Pulling the trigger initiates water flow. Releasing the trigger switches the device off, but the system remains under high pressure. For breaks longer than 5 minutes, the pressure washer should be turned off.
- Spray Pattern Adjustment: The spray pattern can be adjusted between narrow jet and wide spray by holding the lance shaft and twisting the nozzle counter-clockwise through a half-turn (180°).
- Pressure Adjustment: Pressure can be adjusted by sliding the front of the nozzle forwards for low pressure and backwards for high pressure. Increasing the distance from the cleaning surface or adjusting to a wider spray angle also lowers the pressure.
- Detergent Application: The machine includes an integral detergent tank. To apply cleaning agents, the detergent filler cap is removed, the tank is filled with approved detergents (such as CLARKE Traffic Film Remover or CLARKE Wash & Wax), and the cap is replaced. The nozzle is then slid forwards to the low-pressure setting, and the pressure washer is used as normal.
- Shutting Down: To shut down, the ON/OFF switch is set to OFF, the water supply is turned off at the tap, and residual pressure in the pump and hose is released by squeezing the trigger until no more water comes out. The trigger lock is engaged, and the machine is disconnected from the mains power supply. The hose is wound onto the reel, and the spray gun/lance is stored in its holder.
Maintenance Features:
Regular maintenance is essential for the longevity and safe operation of the pressure washer.
- Safety Precaution: Always disconnect the machine from the power supply by removing the plug during cleaning, maintenance, or when replacing parts.
- Nozzle Cleaning: If the nozzle becomes partially clogged, leading to excessive pressure or pulsating pump pressure, it needs cleaning. First, turn off the power washer and water supply, then pull the trigger to relieve pressure. Disconnect the lance from the spray gun. Backflush loose particles by directing water into the end of the lance for 30 seconds. If the obstruction persists, use the supplied nozzle cleaning tool to clear it carefully. Reconnect the lance and turn on the water supply.
- Water Inlet Filter Cleaning: The water inlet filter should be checked and cleaned periodically. Remove the inlet filter from the pressure washer, clean it by flushing both sides with water, and then replace it, ensuring the tapered side faces in. The pressure washer must not be operated without the filter installed.
- Storage: After use, the pressure washer should be thoroughly cleaned and stored in a clean, dry place. It is crucial to avoid storing the machine at freezing temperatures, as residual water in the high-pressure pump or hose assembly can cause permanent damage if it freezes.
- Never direct the spray towards any person, animal, electrical wiring, or equipment, or the machine itself.
- Never hold a finger over the high-pressure nozzle.
- Only allow trained personnel familiar with safety precautions to operate the machine.
- Do not operate with covers removed or attempt repairs; refer to a Clarke dealer.
- Only supply water to the water inlet; never use flammable liquids/solvents in the detergent bottle.
- Always release residual pressure before disconnecting hoses or accessories.
- Keep the machine dry and clear of water spray.
- Wear protective clothing and safety glasses.
- Grip the gun firmly, anticipating kickback.
- Respect local water company requirements; a system separator (backflow preventer) is required for connection to mains drinking water supply.
- Disconnect from water supply and drain completely when not in use.
- Use only manufacturer-recommended accessories, replacement parts, cleaning agents, hoses, fittings, and couplings.
- Water that has flowed through a system separator is non-drinkable.
- The machine is recommended to be connected to the mains supply via a Residual Current Device (RCD).
This comprehensive overview highlights the essential aspects of the CLARKE Power Washer, JET 9500, ensuring users can operate and maintain it effectively and safely.
