Internal inspection of the pressure vessel by a competent individual
Inspection every 10 years:
Strength test of the pressure vessel by appointed body
Notes
Operating parameters:
The current settings, e.g. maximum line pressure [Line Pressure max.] and
minimum line pressure [Line Pressure min.] should be documented in the customer operations log. The
operating log should also contain records and results of maintenance work and inspections. This will
enable Gardner Denver to determine the specific service that your compressor needs.
Maintenance work:
The individual maintenance tasks that the service personnel can carry out, are
detailed in the following chapter. All other maintenance work must be performed by trained service
personnel using the repair manual.
Service cycles:
The earliest date always applies; i.e. if the operating hours are reached before the
calendar date, then the service in question must be carried out.
Servicing kits:
To identify the correct servicing kit, see the following table "Part numbers for servicing
kits".

Replacement times for the filter pad
The operating modes and the quality of the suction
air (e.g. dust content) have a significant impact on
the service life of the filter pad.
The filter pad should be inspected for dust
accumulation at least weekly; daily if possible.
In these usage scenarios, shorter replacement
intervals are possible.
As soon as one of the filter pads shows a defect, it
must be replaced.
