5.2 Seals and radial shaft sealing rings
Sealing elements and shaft sealing rings must, for safety rea-
sons, always be replaced after maintenance work involving
opening, removing or otherwise modifying sealing elements.
5.3 Micro-fi lters
The degree of clogging of the fi lter mats must be checked at
regular intervals in dependence on the conditions of use or
ambient conditions and any applicable environmental protec-
tion guidelines. This means that the user is responsible for
ensuring that the fi lters are permeable.
5.4 V-belt (in appliances supplied complete with V-belt
drive)
The minimum service life of the V-belt in use is 25,000 hours.
The V-belt tension must be checked after approximately
5,000 operating hours (refer to label for belt tension values
and setting values). New V-belts must be checked after a
running-in period of 2 hours and retensioned if necessary
(data see chapter 11 technical specifi cations).

plate (59) respectively on the blower base (11).
Replacing/retensioning the V-belt:
• Remove the grating (55) or belt guard (27).
• Undo the hexagon bolt (60) or tensioning bolt on the
motor tensioning rail (43).
• Undo the hexagon bolt (58) or tensioning bolt on the
motor tensioning rail (43).
• Move the motor including support fl ange plate towards the
support fl ange housing.
• Remove the faulty V-belt (26).

5.5 Cleaning
There is a high risk of injury on the inside of the device due to
rotating parts during operation. Decommission the device in
all cases and wait until all moving parts have stopped before
opening, reaching in or inserting tools into the device. Secure
the device reliably against it being accidentally restarted dur-
ing the entire period.
Also make sure that no other dangerous situation can arise
when restarting after a standstill, e.g. as a result of a power
failure or blockages.
Cleaning or maintenance must not lead to damage or modi-
fi cations to the device and its components that would infl u-
ence safety or health protection and, for example, impair the
balanced state of the impeller.
When starting up the blower, make sure that all tools or other
foreign objects have been removed from inside the device
and that all covers and protective grilles have been attached
correctly.
