MAINTENANCE AND SERVICE
Maintenance and service are decisive for ensur-
ing that the compressor can fulfil the requirements
made of it for fault-free operation and running
time. Therefore the adherence to the prescribed
maintenance schedule and the careful execution
of all maintenance and service work are indispens-
able.
Support is available from your responsible Gard-
ner Denver agency. They will create an individual
maintenance plan for you.
