Changing times for the filter mat
The operating modes and the quality of the suctioned
air (e.g. dust content) has a strong influence on the filter
service life.
The filter should be checked on a weekly basis,
eventually daily basis, for dust build-up. In these cases
the intervals between changes may be shorter.

10.15 Maintenance notes and lubricant
recommendations for stationary
compressors
Lubricant recommendations
Please note that proper lubrication can significantly
increase the lifespan of your compressor system.
In accordance with valid accident prevention
regulations, lubricating oils should be used whose
characteristics correspond to the expected operating
conditions.
Avoid mixing different lubricating oils, i.e. when
changing the oil type, first completely drain the old oil
from the oil circuit.
If seal temperatures are constantly above 195 °F divide
the oil change intervals given in Section 10.3
(Maintenance schedule) by half.
The exact oil change schedule according to the actual
operating conditions should be set by performing oil
tests.
Material Safety Data Sheets (MSDS) are available for
all Gardner Denver lubricants from your authorized
