tenance of the individual components or sub-

agreement / with the knowledge and release of
the operator.

resulting from the operating manual for the com-
ponents are to be complied with.
4. Appropriate special tools approved for the poten-
tially explosive atmosphere must be used.
5. Only original spare parts may be used. Other-
wise, any claim of warranty is void or, in case of
damage, the operator is liable for this.

book) must also include the checking of the
secure fit of the threaded connections for the
coupling safety hood.

The screw compressor package must be serviced by
appropriately trained operating staff only. For all
maintenance work, the maintenance instructions

A maintenance checklist is part of the product docu-
mentation. The maintenance certificates in the main-

During the guarantee period, these confirmed main-
tenance certificates are a prerequisite for any claims
under the guarantee.
The responsible certified specialist company must be
informed if any repairs are required.
All maintenance and service tasks have to be carried
out with care to preserve the functionality of the
screw compressor package. Guarantee claims will
not be valid if the customer failed to follow the main-
tenance instructions.
