Press enter key (5), S (S standing for Service)
appears. Use key (12) to scroll to r005 (register 005)
and press enter key (5), the actual reading of the service
timer will be shown in kHrs (hours x 1000) .

4002 hours since previous service.

4. Stop the compressor, switch off the voltage and carry
out the service actions as explained in the maintenance

Important
- The longer interval service actions must include the
shorter interval actions.
In the example above, carry out all service operations
belonging to the 8000 running hours interval as well as
those belonging to the 4000 running hours interval.
- 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.
5. After servicing, reset the service timer (see section 7.5).
7 Scrolling through all screens
Scroll keys (12 and 13) can be used to scroll through all screens.
The screens are divided in register screens (numbered as r001,
r002,...) and parameter screens (numbered as P001,
P002,...).
During scrolling, the numbers of the screens appear consecutively.
For most screens, the unit of measurement and the related
pictograph are shown together with the screen number.
In case of a warning or shut-down, an extra register screen (r000)
is accessible.
