8HDS 1000 DEIII. Operation1. Initial operation (cold-water mode)– Open water inlet.– Unit switch to position “SYMBOL Burner off”.– Start engine according to operating instructions.– Retract lever of handgun.The pump first extracts air out of the unit. After a short time water will come out of the nozzle.Caution! The water jet being emitted effects a recoil force or torque on the handgun,so grip the handgun firmly.– If during operation you release the lever of the handgun, the overflow valve will open and a watercirculation will take place inside the pump. At the same time, the revolutions per minute of the enginewill be reduced from operating speed to idling speed by the speed regulator fitted to the cylinder head.– The switch-over pressure of approx. 240 bar remains in the system between overflow valve andhandgun.– A further retraction of the lever releases this pressure, the overflow valve closes, the engineaccelerates to operating speed and the spraying pressure is reasserted.2. Hot water mode– Set the temperature regulator to the desired working temperature, the maximum being 98 °C. Theburner is thereby switched on. At a maximum demand on the pump, the water temperature rises inaccordance with the setting on the thermostat, but not above 98 °C.3. Regulate pressure and water flowThe unit is fitted with a servopress device. Operating pressure and rate of flow can be infinitely adjustedby the regulator wheel on the handgun. The temperature regulator may be set to a maximum of 98 °C.4. Steam stage modeIf the temperature regulator is to be set higher than 98 °C, the nozzle on the spray lance should beexchanged for a steam nozzle.– Set the temperature regulator to 150 °C.– Set the regulator wheel on the handgun to MIN stop position.5. Spraying with cleaning agent– Hang the cleaning agent hose with filter into container of cleaning agent.– The proportion of cleaning agent in the water flow can be adjusted infinitely up to a rate ofapprox. 5 %.Cleaning methodsa) Single-step methodSpray on the cleaning agent with high pressure.b) Two-step methodSpray on the cleaning agent with low pressure and leave it to take effect (1 – 5 minutes).Spray away the dirt with the high-pressure water jet (without cleaning agent).
