[. . . ] This indicates tips and instructions to simplify work and to ensure safe operation. This symbol is used to mark safety instructions that must be observed to prevent damage to the machine and its performance. Do not direct the jet towards live animals. During operation of the cleaner, recoil forces are produced at the spraying device and, when the spray lance is held at an angle, a torque is also created. [. . . ] The pressure-bearing parts of this high-pressure cleaner have been manufactured in accordance with § 9 of the German Pressure Vessels Ordinance and successfully subjected to a pressure test. Safety devices Unacceptably high pressure is fed back without residual pressure via a bypass line into the intake line of the pump when the safety device is tripped. If the conveying capacity falls below a fixed value, the builtin flow monitor automatically switches off the oil burner. The safety devices are factory set and leaded, and must not be adjusted. It can be used for cleaning agricultural and construction equipment, stables, vehicles, rusty surfaces, etc. The cleaner has not been approved for cleaning surfaces which comes into contact with food. chapter 5 describes the use of the high-pressure cleaner for various cleaning jobs. Always use the cleaner as described in these operating instructions. Any other use may damage the cleaner or the surface to be cleaned or may result in severe injury to persons. See fold-out page at front of these operating instructions.

Catch the liquid discharging at first (approx. Move the main switch into position 'Cold Water' (A) The control electronics system performs a self-test, all the LEDs light up once. Always remove any dirt from the nipple before connecting the spray lance to the spray gun. When the water flow is even, continue with the following steps 1. Pull the blue quick-release grip (A) of the spray gun backwards. Insert the nipple of the spray lance (B) into the quickrelease connection and release it. Pull the spray lance (or other accessory) forwards to check that it is securely attached to the spray gun. In the case of appliances with a hose reel: In hot water mode, unwind the high-pressure hose fully from the hose reel, as otherwise the hose reel may become warped due to the effects of the heat. Move main switch into the position 'Hot Water' (B) and select the required temperature on the temperature control 2. unlock the spray gun and actuate it The burner switches on. In case of interruptions in work: Also be sure to insert the safety catch even during short interruptions in work (see Fig. [. . . ] During suction operate the spray gun two or three times. The machine is protected against frost when antifreeze solution emerges from the spray gun. To avoid any risks, store the cleaner temporarily in a heated room in upright position. When the machine is put into service again, the antifreeze solution can be collected and stored for future use. [. . . ]
