User manual RYOBI RYAN-B280

[. . . ] Do not touch the plug and/or socket with wet hands. According to DIN 1988, power-jet cleaners may only be connected to the mains drinking water supply if a backflow preventer valve with drain facility is installed in the supply hose. CONTAMINATION HAZARD Maintenance and/or repair of electrical components must be carried out by qualified staff. Do not use the cleaner if the high pressure hose is dama- 10 Check that the data plates are affixed to the cleaner, if not, inform your dealer. [. . . ] 11 The cleaner must be used standing on a secure, stable surface, positioned as shown. Not for professional use (for three-phase or industrial motors only), and only for operation at temperatures above 0°C. 2 When using chemical detergents, use only highly 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 and rotate it 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 intake water temperature must not exceed 60°C (122°F). 6E Discharge residual pressure by pressing the trigger until no more water comes out of the adjustable nozzle. Operate the cleaner with noncorrosive/non-toxic antifreeze before storing for the winter. - Continuous pressure regulation from min. - Motor power supply cut-out in case of power failure. prevents inopportune motor restart (IEC 335-2 regulation). - Time delay device on motor ~ 8 seconds after release of the gun trigger. Do not use the appliance for prolonged periods at zero pressure (bypass recycling) or allow the water to overheat since these could damage the sealing system. - User-friendly , long-life ON-OFF switches. The controls on the control panel of the appliance are of the TOUCH-PAD PUSHBUTTON type, thus ensuring easy operation and optimum protection against water CAUTION: with THREE-PHASE motor (~ 3) on first use the plug must be connected with the polarity set so that the motor fan turns clockwise. Ensure that this is the case by checking that the motor fan turns in the correct direction. Before working on the cleaner, disconnect the plug from the power supply socket. [. . . ] 3 For optimum service from the TRONIC appliance, the gun should NOT be opened and closed at intervals of less than 4-5 seconds. 5H 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. For correct operation of the TSS, once the trigger has been released it must not be pressed again for at least 4÷ 5 seconds. [. . . ]
