4. Open the venting screw at the filter until all air has escaped from the filter. 5. Close the venting screw. 6. Start the engine (see "Operation"). 7. Pull the breather hose away from the device. Water escapes here during the venting process. 8. Open the pump venting lever until an even flow of water escapes from the breather hose; do this for at least 90 seconds. 9. Close the pump venting lever. The water shortage safeguard switches the device off in the case of insufficient advance pressure. 10. In this case, turn the key-operated switch to "0" to reset the water shortage safeguard. 11. Restart the engine to continue the venting process. 12. Keep switching the device Off/On until it runs faultfree in depressurised circulation/idle mode. Venting the high-pressure system (Advanced variant only) 1. Vent the low-pressure system as described above. 2. Remove the high-pressure nozzle. 3. Pull and hold the trigger of the high-pressure gun with the motor at a standstill. 4. Wait until an even flow of water escapes from the spray lance (wait at least 90 seconds). 5. Release the trigger of the high-pressure gun. 6. Turn the trigger to 1/ON. ƽ DANGER A high-pressure water jet is emitted from the spray lance, even when operating without a high-pressure nozzle. The high-pressure jet can cause injuries. Do not point the spray lance at people. 7. Pull the trigger of the high-pressure gun and hold it until an even water stream is emitted. 8. If the device exhibits pulsing behaviour for a longer period of time when the high-pressure gun is open, turn the trigger to 0/OFF. 9. Turn the trigger to 1/ON to continue venting. 10. Keep switching the device Off/On until an even water stream is emitted. Positioning the control panel The control panel can be positioned at 5 locations on the frame of the device. This allows the most favourable position to be selected for every application. 1. Slide the control panel upwards and pull it away from the frame of the device. 2. Align the bolts at the rear of the control panel with the holes of the selected mounting position. 3. Press the control panel onto the tubular frame and engage it in position. Operation Routing the high-pressure hose 1. Route the high-pressure hose so that it cannot be damaged by mechanical influences or vibrations. a Do not route the hose under tension because pressure changes can alter the length of the hose. b Do not bend it beyond the smallest permissible ´bending radius. c Do not twist the hose (torsion). d Avoid abrasion on other hoses, moving parts, edges rough surfaces. e Protect loosely routed hoses against damage, abrasion and deformation by using hose bridges. f Connect the hose end with and inner thread first if the other hose end has a union nut. g Do not use sealants (e.g. hemp, sealing tape). h Adhere to the design specifications of the valve when connecting to a valve (e.g. multiple-consumer valve). i Protect hoses from sunlight and heat. 2. Secure the high-pressure hose to the device and high-pressure gun suing hose safety catches. Function test ƽ DANGER Risk of injury due to uncontrolled emission of a maximum-pressure water stream. A maximum-pressure water stream can cause fatal injuries. Perform the following checks each tie before starting operation. 1. Check that the high-pressure gun is correctly in- stalled. 2. Check that the high-pressure gun is correctly con- nected to the high-pressure cleaner. 3. Check that the water supply satisfies the require- ments in the "Technical data" section and is correctly implemented. 4. Vent the high-pressure cleaner as described in the "Water connection" section. 5. Rinse the high-pressure cleaner, hose and highpressure gun with fresh water while depressurised. 6. Check that the device corresponds to the as-delivered state and that no impermissible modifications have been made. Functional test of the high-pressure gun (dump gun) 1. Check to ensure the trigger and safety latch move freely: a The trigger must independently return to the initial position and engage in the safety latch when released. b It should only be possible to actuate the trigger when the safety latch is actuated. 2. With the device switched off, check that the water stream is immediately emitted at the bypass pipe when the trigger is released. 3. Repeat step 2 while the device is running. Operation The working pressure is shown on the pressure gauge. 1. Always initially direct the high-pressure jet at the ob- ject to be cleaned from a distance to avoid damage due to excessive pressure. Switching on the device 1. Open the water inlet. 2. Vent the device (see chapter "Venting the device"). 3. Turn the fuel cock to the "ON" position. 4. Raise the engine speed lever as far as possible (to the lowest speed). 5. Turn the key-operated switch to position "1". 6. Wait until the engine preheating indicator lamp goes out. ATTENTION Risk of damage The starter can overheat. Interrupt the start-up attempt if the engine does not start after 15 seconds. Wait at least 30 seconds between 2 start-up attempts. 7. Turn the key-operated switch beyond position "1" until the engine starts. 8. Release the key-operated switch; it will automatical- ly return to position "1". 9. Unlock the high-pressure gun. a Dump gun: Press the safety latch of the highpressure gun downward. b Dry shut: Pivot the safety latch of the high-pressure gun upward. ƽ DANGER Risk of injury due to forces at the high-pressure hose during pressure changes The user can loose balance and fall due to movement of the high-pressure hose. Assume a stable posture before using the device. 10. Pull the trigger. 11. Adjust the working pressure by adjusting the engine speed lever. Do not exceed 100 MPa (1000 bar). ● Increase speed - Lower the engine speed lever. ● Decrease speed - Raise the engine speed lever. Note If the EU version is operated at a lower engine speed or in an idle mode for a prolonged period, the diesel particulate filter will need to be regenerated more frequently. The risk of damage to the diesel particulate filter also increases. Interrupting operation 1. Release the trigger. The safety latch secures the trigger against unintentional operation. 2. Turn the key-operated switch to position "0". ƽ DANGER Risk of injury due to an uncontrolled high-pressure water jet. A high-pressure water jet can cause fatal injuries. Never hang up the high-pressure gun by the trigger but rather by the gun housing. Functionality check be restarting ƽ DANGER Risk of injury due to uncontrolled emission of a maximum-pressure water stream. A maximum-pressure water stream can cause fatal injuries. Perform the following checks each time before resuming work. 1. Check that the high-pressure gun is correctly in- stalled. 2. Check that the high-pressure gun is correctly con- nected to the high-pressure cleaner. 3. Check that the system is vented. 4. With the device switched off, check that the water stream is immediately emitted at the bypass pipe when the trigger is released. 5. Repeat step 4 while the device is running. 6. Actuate the high-pressure gun several times in a safe location with the device switched on and check the valves at the bypass and leakage bores for leaks. 7. Check to ensure the trigger and safety latch move freely: a The trigger must independently return to the ini- tial position and engage in the safety latch when released. b It should only be possible to actuate the trigger when the safety latch is actuated.
