The maximum vacuum value in relation to the hose cross-section is specified on the label. The actual value can be read on the pressure gauge. For the values applicable to this device, see chapter Reading the minimum volumetric flow. If this value is not reached, the filter must be replaced, (see chapter Replacing the main filter). The various different hose cross-sections allow adaptation to the various different connection cross-sections of the accessories.

	Micro-fleece (Order no. 9.990-103.0)
	Main filter (Order no. 9.439-542.0)

2. Pull the bow handle up.

   The dirt receptacle is unlocked and lowered.

3. Pull the dirt receptacle out of the device by the bow handle.

---



4. Loosen the clamping straps on the dirt receptacle.

5. Remove the upper part of the dirt receptacle by the bow handle.

6. Fill the inert liquid water or oil into the dirt receptacle until the filling level reaches the mark on the filling level indicator.

7. When fitting the upper part of the dirt receptacle, make sure that the float ball is inserted into the corresponding guide.

WARNING

Improper handling when locking the dirt receptacle

Risk of crushing

Under no circumstances should you hold your hands between the dirt receptacle and filter ring or allow them to come close to the lifting mechanism while locking it.

Lock the dirt receptacle by operating the bow handle with both hands.

---



ATTENTION

Static charge of the dirt receptacle

Ignition of dusts

Make sure that the grounding on the chassis is in contact with the dirt receptacle.

8. Fit the dirt receptacle in the reverse sequence and lock it with the bow handle.

The dirt receptacle must be emptied when filled up to the mark. The device does not switch off automatically when the maximum filling level is exceeded.

1. Check the dirt receptacle filling level regularly.

2. Make sure that no more than 8 litres of material are sucked in during vacuuming.

1. Plug the mains plug into the socket.

2. Switch on the device via the suction turbine power switches.

   Note

   Always switch the suction turbines on and off one after the other. For the correct function of the pressure gauge for monitoring the minimum volume flow, all suction turbines must be switched on.

   Note

   In most application cases it is sufficient that you vacuum with one suction turbine. If necessary, switch on the 2nd suction turbine. However, do not operate the device with both suction turbines for longer than 15 min. This can cause too much humid air to prematurely wet the main filter. If necessary, let the main filter dry afterwards or replace it (see chapter Replacing the main filter).

3. Start the vacuuming process.

1. Regularly check the filling level in the dirt receptacle, since the device does not switch off automatically.

   Note

   The device is equipped with a mechanical monitoring unit. This monitoring unit interrupts the airflow when the inert liquid falls below the minimum filling level. Refill with inert liquid to continue the vacuuming process (see chapter Fill the dirt receptacle with inert liquid).

2. Make sure that no more than 8 litres of material are sucked in during vacuuming.

3. If necessary, empty the dirt receptacle (see chapter Emptying the dirt receptacle).

4. If necessary, replace the main filter (see chapter Replacing the main filter).

   Note

   If the dirt receptacle is filled with an inert liquid, moist air may flow through the main filter during suction and soak it. Check the main filter for moisture after the vacuuming process. If necessary, let the main filter dry or replace it (see chapter Replacing the main filter).

A pressure gauge showing the vacuum inside the device is mounted on the front of the device. The main filter must be cleaned when the maximum vacuum (see table) is reached, see chapter Replacing the main filter). This value depends on the device performance and the suction hose used. If the vacuum is not significantly reduced by replacing the filter, there must be another problem (see chapter Troubleshooting guide).

1. Switch off the device via the suction turbine power switches.

2. Pull out the mains plug.

3. Disconnect the earth terminal from the external equipotential bonding.

1. Remove the accessories.

2. Close the suction connection (see chapter Closing the suction connection).

3. Remove the accessories and, if necessary, flush with water and allow to dry.

4. Empty the dirt receptacle (see chapter Emptying the dirt receptacle).

5. Vacuum the inside and outside of the device and clean with a moist cloth.

The dirt receptacle must be emptied if necessary and after each use.

The inlet opening or the suction hose are closed.

Regularly check the filling level in the dirt receptacle, since the device does not switch off automatically.

1. Switch off the device.

2. Secure the device with the parking brakes.

If the malfunction cannot be corrected, the device must be checked by the Customer Service department.

• Suction turbine does not start up 

• Suction power decreases 

• Suction power not present 

• Escaping dust when vacuuming 

Remedy:

1. Check the socket and the power supply fuse.

2. Check the mains cable and the mains plug of the device.

3. Switch the device on.

Remedy:

1. Close the unsealed suction connection (see chapter Closing the suction connection).

2. Remove the blockages from the suction nozzle, the suction pipe or the suction hose.

3. Check that the suction head and the dirt receptacle are correctly seated.

4. Empty the dirt receptacle (see chapter Emptying the dirt receptacle).

5. Check the seating of the filter and correct if necessary.

6. Replace the main filter (see chapter Replacing the main filter).

7. Replace the micro-fleece (see chapter Replacing the micro-fleece).

8. Check the condition of the inert liquid.

   2. Check the quality of the inert liquid, replace the inert liquid if necessary (see chapter Drain the inert liquid from the dirt receptacle and chapter Fill the dirt receptacle with inert liquid).

Cause:

The mechanical switch-off interrupts the volume flow because there is too little inert liquid in the dirt receptacle.

Remedy:

1. Top up the inert liquid (see chapter Fill the dirt receptacle with inert liquid).

Remedy:

1. Check the seating of the dirt receptacle.

2. Check the seating of the filter and correct if necessary.
