Note!
Repairs must be carried out by the manufacturer.
We cannot accept any liability for repairs carried
out by third parties.
5.1
Conveyor blowers are subject to wear and must be
checked at regular intervalls, depending on the type of con-
veyed media. Wear parts such as the impeller should be re-
placed on time as bearings may be damaged by imbalance
due to uneven wearing.
5.2
Replacement of the impeller and cleaning work are car-
ried out by unscrewing of the housing cover. Power supply
must be cut o
ff
during this work. The impeller must be stand-
ing still and be secured against restarting.
5.3
There is no maintenance work necessary on the drive
motor. The lubrication of the enclosed deep-groove ball bear-
ings is su
ffi
cient for their entire service life.
5.4 Ball bearings
Note!
The fans from Elektror are equipped with sealed
deep groove ball bearings, which do not require
relubrication.
Note!
Check the ball bearings during servicing and
prior to recommissioning.
Operation is only permitted with
fl
awless ball
bearings!
Note!
In the event of frequently starting up and shutting
down, premature replacement of the bearings
will be required. Determining the time for repla-
cing the bearings is the sole responsibility of the
maintenance and servicing personnel, who must
make a safety judgement.

5.5 Seals and radial shaft sealing rings
If sealing elements and/or radial shaft seals are included
in the scope of delivery, for safety reasons they should be
replaced at each maintenance, where sealing elements are
opened removed or otherwise altered.
5.6 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 in
fl
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.

ON TAKING OUT OF OPERATION AND
REMOVAL
The disconnection of all electrical connections and any other
