3. Air filtration (picture
���
)
The capacity of the compressor can be reduced
if the air inlet filters are not maintained correctly.
The filter cartridges (f
1
) have to be cleaned depending on
the amount of contamination. Cleaning can be carried out
by blowing out with compressed air. Replace filters if
contaminated completely.
Wash cartridges soiled by oil or grease in lukewarm water
with a non-foaming detergent. Under no circumstances
are petrol, leaching solutions or hot liquids to be used.
Re-insert filters only in dry condition.
Replace damaged cartridges without fail.
The filter cartridges (f
1
) can be removed from the filter
housing by unscrewing the fixing knobs (g) and removing
the filter housing cover (h) with gasket. Cleaning or
replacing the filter cartridges (f). Re-assemble in reverse
order.
Filter Cartridge (Optional Extras): The suction filter (ZAF)
should be cleaned every 250 operating hours and changed
every 3000 operating hours. Changing the filter: unscrew
wing nut. Remove filter cover and filter cartridge. The filter
cartridge can be cleaned by knocking out by hand or by
using compressed air. Replace the filter cartridge if nec-
essary.
Reassemble in reverse order.
4. Coupling (picture
���
)
The coupling rubbers (k) are wearing parts and should be
checked regularly. When the coupling rubbers are worn
this can be detected by a knocking sound when the
compressor pump is started.
Defective coupling rubbers can cause extensive
damage and even in some extreme cases break
the rotor shaft.
To check the coupling stop the motor (m) and isolate.
Remove the screws (s
5
). Pull off the motor together with
the motor side coupling half (q). If the coupling rubbers (k)
are damaged remove the circlips (l) from the coupling
bolt (r) and exchange the coupling rubbers (k). Leave the
spacer (p) in place, check the coupling bolts (r) for any
wear and replace if necessary. To replace, remove the
screws (s
6
) on the motor flange (n), remove the circlip (l
1
),
pull off the coupling (q
1
) and fan (v) complete from the
shaft, remove the nut (w) with washer (u) and exchange
the coupling bolts.
Re-assemble in reverse order.
5. Cooling (pictures
���
and
���
)
Should the compressor be mounted in a position subject dust and dirt it is to expected that this will get in between the cooling pipes. We therefore,
recommend that all dust and dirt be removed approximately every 6 months by blowing air into the exhaust parts (F
1
) of the cooling fans and into
the spaces between the cooling segment (E
1
). This should be carried out when the compressor is operating so that any loosened dust may escape
through the exhaust parts (F
1
) of the cooling fans.
