At the end of the service life of the compressor, proceed as
follows:
1. Stop the compressor and close the air outlet valve.
2. Switch off the voltage and disconnect the compressor from
the mains.
3. Depressurize the compressor by opening plug (5-Fig. 3.3)
one turn and by opening valve (1-Fig. 3.2).
4. Shut off and depressurize the part of the air net which is
connected to the outlet valve. Disconnect the compressor
air outlet pipe from the air net.
5. Drain the oil and condensate circuits.

4 Maintenance
Attention
Apply all relevant safety precautions, including those mentioned
in this book.
Before starting any maintenance or repairs:
1. For GA Workplace/Workplace FF, press stop button (1-
Fig. 3.5), wait until the compressor has stopped (approx.
30 seconds), press emergency stop button (S3-Fig. 3.4) and
switch off the voltage.
For Pack/Pack FF, press stop button (1-Fig. 3.7), wait until
the compressor has stopped (approx. 30 seconds), press
emergency stop button (S3-Fig. 3.6) and switch off the
voltage.
2. Close air outlet valve (1-Figs. 3.4/3.6) and depressurize by
opening plug (5-Fig. 3.3) one turn and by opening valve (1-
Fig. 3.2) (not provided on GA Pack).

The motor bearings are greased for life
4.2 Service actions for GA Pack/Pack FF
GA Pack and Pack FF are provided with the Elektronikon I
regulator (Fig. 3.7).
Besides the daily and 3-monthly checks, the service operations
are grouped in time intervals (running hours); see section 4.4.
The regulator has a programmable service timer. When the
timer reaches the programmed interval, LED (8-Fig. 3.7) will
light up. Press key (12-Fig. 3.7), r000 appears. Press key
(5-Fig. 3.7), S (S standing for Service) appears. In this
case, check the running hours. Carry out the service operations
corresponding to the running hours as specified in the schedule
of section 4.4.
Reset the service timer after servicing. For detailed information,
consult the User manual for Elektronikon I and II regulators,
Part 1, section 6.
Important
If using mineral oil instead of Atlas Copco Roto-injectfluid,
the service timer interval has to be decreased: 500 running hours
for 13 bar (175 psi) units and 1000 running hours for 7.5-10
bar (100-150 psi) units.
4.3 Service plans for GA Workplace/
Workplace FF
GA Workplace and Workplace FF are provided with the
Elektronikon II regulator (Fig. 3.5).
Besides the daily and 3-monthly checks, the service operations
are grouped in plans, called Service plans A, B or C; see section
4.4.
Each plan has a programmed time interval at which all service
actions belonging to that plan are to be carried out.
When reaching the interval, a message will appear on the screen
indicating which Service plans are to be carried out. After
servicing, the intervals are to be reset. For detailed information,
consult the User manual for Elektronikon I and II regulators,
Part 2, sections 5, 12 and 15.
Important
Always consult Atlas Copco in case any timer setting should
be changed.
