4 MAINTENANCE

Before carrying out any maintenance or repair:

1.Stop the compressor, switch off the voltage and open the isolating switch.

2.Close the air outlet valve (2-Figs. 1.2/1.4 or 3-Figs. 1.5/1.6) and open the manual drain valve: valve (1- Fig. 1.9) on Multi or the valve underneath the air receiver, if provided.

4.1 Compressor drive motors

The motor bearings are greased for life.

4.2 Preventive maintenance schedule for the compressor

The schedule comprises a summary of the maintenance instructions. Read the respective section before taking maintenance measures. The "longer interval" checks must also include the "shorter interval" checks.

Carry out the service operations at the period or running hours mentioned below, whichever interval comes first.

When servicing, replace all disengaged packings, e.g. gaskets, O-rings, washers.

Important

Use only authorized parts. Any damage or malfunction by the use of unauthorized parts is not covered by Warranty or Product Liability.

Service plans on SF Multi

A number of service operations are grouped in plans, called Service plans I, A, B or D; see the schedule below.

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 section 8.3.

Important

Always consult Atlas Copco in case any timer setting should be changed.
