5.10.5 Inserting panel air filters
1. Insert the thoroughly cleaned or new
panel air filter (Fig.
26/5) from the
correct side in the filter support
frame.
Pay attention to the labeling on
the side of the panel air filter
(Fig.
26/5)!
2. Replace the filter cover (Fig.
26/8).
3. Close the bottom filter cover locks:
Pivot the hinged locks (Fig.
26/6)
over the edge of the filter cover
(Fig.
26/8).
4. Close the top filter cover locks:
Screw the knurled screws (Fig.
26/1)
on the threaded pins (Fig.
26/4).
5. Close the hood (Fig.
26/7) so that it
audibly locks.
5.10.6 Checking the suction turbine
1. Switch the machine on,
refer to Section 3.3.1.
2. Clean a dusty surface for test pur-
poses, refer to Section 3.3.4.
3. Switch the machine off,
refer to Section 3.3.5.
4. Remove the dirt hoppers,
refer to Section 5.9.1.
5. Check whether dust has accumulat-
ed on the inner side of the panel air
filter (Fig.
26/5).
6. If you have the impression that the
suction turbine does not work or dust
escapes from the machine, contact a
PowerBoss service center.
Do not open the hood
(Fig.
26/7) when the engine is
running. Risk of injury through
belt drive and rotating
fan(Fig.
26/3)!
5.10.7 Checking the filter system for
leaks
Do not open the hood
(Fig.
26/7) when the engine is
running. Risk of injury through
belt drive and rotating fan
(Fig.
26/3)!
1. When the engine is switched off,
hood (Fig.
26/7) is open and filter
cover (Fig.
26/8) removed, check
whether dust escapes at the edges
of the panel air filter (Fig.
26/5).
2. If this is the case, check the sealing
strips (Fig.
26/2), refer to Section
5.10.4 and replace, if necessary.
3. Check the panel air filter (Fig.
26/5)
and replace, if necessary. The frame
of the panel air filter (Fig.
26/5) must
not be twisted nor show signs of
damage. Ensure that the panel air fil-
ter (Fig.
26/5) has been inserted true
to side, refer to Section 5.10.5.
4. Repeat this test a certain time after
cleaning. If dust continues to escape
at the edges of the panel air filter
(Fig.
26/5), contact a PowerBoss
service center.
