Maintenance and Care
5.10.1 Cleaning the fine particle filter
Check the coarse particle sieve and
filter hoses daily for accumulations of
dirt, clean as necessary.
1. Switch the suction turbine off.
2. Agitate the filter system. Actuate the
agitating device (automatic agitating
time approx. 20 sec.) several times,
if necessary.
3. Open the fastening device (Fig. 27/
2). Pull out the pivoting lever (Fig. 27/
3) and pivot the filter case (Fig. 27/1)
to the rear. Dry clean the filter hoses
(Fig. 27/6).
4. Pivot the filter case downwards so
that the loose dirt can slide out. If
necessary, switch on the agitating
device.
Do not use liquids to clean the
filter hoses, simply beat clean
or use compressed air.
5. Remove the coarse particle sieve
(Fig. 28/1) and clean it. Reinsert the
coarse particle sieve, pivot the filter
case back in place and close it
properly.

5.10.2 Changing the fine particle
filter
Check the filter hoses every 250
operating hours for signs of wear,
replace if necessary.
1. Open the fastening device (Fig. 27/
2) and pivot the filter case (Fig. 27/1)
out towards the rear.
2. Remove the screws at the corners.
3. Raise the filter package slightly and
unplug the cable in the agitating
motor.
4. Remove the filter package fully.
5. Remove the filter hoses from the
perforated metal plate.
6. Clean the perforated metal plate
(Fig. 27/7) thoroughly, insert new
filter hoses and press on evenly.
Before inserting the new filter
hoses, we recommend heating
the clamping piece a little using
hot air or hot water.
Installation is carried out in the reverse
sequence.
