6.2 Empty Dust Drawer
After reaching the set time interval (see chapter 5.4.2), the dust drawer is requested to be emptied:
♦ An acoustic signal sounds 3 x�
♦ The symbol "dust drawer full" is shown�
♦ In the display "FULL" is shown�
Before removing the dust drawer, a filter cleaning function should
be performed:
⇒ Press Enter key (30) for 2 seconds�
♦ The filter cleaning function is performed.
Once the filter has been cleaned:
⇒ Release the clamp fastener (4A) of the dust drawer�
⇒ Pull the dust drawer (4) out towards the front�
⇒ Remove the retaining ring (16, Fig� 1)�
⇒ Seal the waste bag tightly to prevent dust escaping, remove it,
and ensure disposal�
During disposal, observe local provisions and accident pre-
vention regulations!
Personal protective equipment must be worn depending on
the extracted material.
⇒ Place a new waste bag through the retaining ring and fold the ends over the
retaining ring�
⇒ Place the waste bag with the retaining ring in the dust drawer� The retaining
ring is held in the dust drawer using magnets. Ensure that the waste bag:
- Fits against the side walls of the dust drawer;
- Does not cover the sealing surface�
⇒ Insert the dust drawer again and push it all the way in�
⇒ Close the clamp fastener (4A)�
⇒ Press the Enter key (30) (counter for recording the time interval is reset)�
♦ Acoustic signal acknowledges the information�
♦ Dust drawer display (23) is deleted�
If the dust drawer is not emptied, the "Dust drawer full" and "FULL" symbols are still shown in the
display. After switching the device off and on again, a 3 x acoustic signal is used to indicate the
emptying of the dust drawer.
6.3 Change Fine Filter
The effectiveness of the filter cleaning is determined by monitoring the flow rate (internal pressure sen-
sor)�
If a filter cleaning is required several times in succession after less than 2 hours, this means that the fine
filter is so highly clogged that the filter cleaning does not show sufficient effect and the fine filter has to be
changed�
This is indicated as follows:
♦ The display shows "FILt"
♦ For a period of 15 min�, 2 long beeps are sounded for 3 min at a time�
The error message can be switched off by switching off the suction�
If requested to change the fine filter or the suction performance does not improve substantially or
only for a short period, the fine filter must be changed soon.
Further operation can lead to damage to the device.
► In general, the fine filter should be changed every 2 years.
Do not clean the fine filter manually under any circumstances (e.g., using compressed air, brush-
es, water, etc.). This damages the filter material.
Do not use compressed air!
Using compressed air to blow off deposits of dust is generally not permitted.
