8.13 Checking the compressed air
regulator
Damaging of the machine
NOTICE
when compressed air is
contaminated
Compressed air that does not fulfill the guidelines for
purity according to ISO 8573-1 can damage the
machine.
Check the water separator of the compressed air reg-
ulator daily for contamination.
Never use the machine if there is water, oil or solid
particles in the water separator.
8.13.1 Checking the w ater separator for con-
densate
Condensate in the separator usually points to
compressed air not being dry enough.
1. Check if water, oil or solid particles piled up in the
water separator.
2. If this is the case, switch the machine off imme-
diately and proceed as follows.
3. Disconnect the machine from the compressed air
supply.
4. Check the compressed air supply and make sure
that the compressed air fulfills the requirements for
air purity according to ISO 8573-1. Do not use the
machine until the compressed air fulfills this require-
ment.
5. Drain the water separator by turning the discharge
screw counter-clockwise.
The condensate is blown out downwards under
pressure.
6. Close the discharge screw again by turning it clock-
wise.

8.13.2 Exchanging / cleaning the con-
taminated filter cartridge
You have to clean or exchange the filter cartridge in
the water separator in case of strong contamination.
If the compressed air fulfills the requirements for air
purity according to ISO 8573-1, the filter cartridge
usually does not have to be changed.
You exchange or clean the filter cartridge as follows:

N4+ – Maintenance and do-it-yourself
A strongly contaminated cartridge can lead to a
pressure loss.
If the filter cartridge is contaminated, check the pur-
ity of your compressed air.
1. Disconnect the machine from the compressed air
supply.
2. To remove the bowl of the water separator, do the
following:
a. Press the release and turn the bowl coun-
terclockwise as far as it will go.
b. Pull the bowl off the housing.

3. Unscrew the filter screw below the filter cartridge.
4. Pull out the filter cartridge and clean it if necessary.
A new filter cartridge is available as spare
part from customer service.
5. Insert the new or cleaned filter cartridge and reas-
semble the water separator. While doing so, insert
the release into the recess in the housing and turn
the bowl until it locks into place.
