[. . . ] The high pressure may cause materials to bounce off surfaces at speed; therefore protective clothing and safety goggles MUST BE WORN. DO NOT touch the plug and/or socket with wet hands. DO NOT use the cleaner if the high pressure hose is dam- 10 Check that the data plates are affixed to the cleaner, if not, inform your dealer. [. . . ] 2 When using chemical detergents, only use biodegradable types. 3 Only clean vehicle engines in areas in which suitable oil traps are installed. 1 The safety valve also functions as a pressure limiting valve. When the gun trigger is released, the safety valve opens and the water recirculates through the pump inlet. 1 Fit the lance into the gun by rotating and pushing until the two parts are completely locked. 2 Connect the gun to the high pressure hose. The supply hose must have an internal diameter of at least 13 mm (1/2 in. The water supply must be at least equal to the cleaner delivery capacity. The cleaner must only be used with clean water; use of unfiltered water or corrosive chemicals will damage the cleaner. 3B If the power supply is correct, you may The electric supply connection shall be made by a qualified electrician and comply with IEC 364. It is recommended that the electric supply to this appliance should include either a residual current device that will interrupt the supply if the leakage current to earth exceeds 30 mA for 30 ms or a device which will prove the earth circuit. The machine may cause electrical disturbances when starting. If the motor stops and fails to restart, wait 2-3 minutes before restarting. 5A, then press the trigger for a few seconds to allow air to escape and to discharge residual pressure in the pipes. 5C) with automatic delivery flow cut-off: when the trigger is released, the dynamic pressure automatically cuts out the motor. When the trigger is pressed the pressure drop automatically starts the motor and the pressure is restored with a very slight delay. [. . . ] The pump does not operate at the prescribed pressure Sudden changes in pump pressure The motor buzzes but fails to start Motor does not start Water leakages Excess noise Oil leaks For TSS MODELS ONLY: Motor starts even though the trigger is released For TSS MODELS ONLY: No water when lever is operated (when supply hose is connected) Power cable damaged Nozzle worn Water filter fouled Water supply pressure low Air being sucked into the system Air in pump Replace nozzle Clean filter Turn on the water supply tap fully Check that hose fittings are tight Switch off the cleaner and operate the gun until a steady flow of water is obtained. Then switch cleaner back on Pull adjustable nozzle back (+) Connect cleaner to mains water supply Reduce temperature Disconnect power supply, discharge pressure and clean with tool provided Have seals replaced by an authorised service centre Check that the plug is firmly in the socket and that mains power is present.
