Model: HV1/140A 

5. INSPECTION AND MAINTENANCE 

 

IMPORTANT: PERSONAL SAFETY 
Before starting any kind of work on the compressor, the electricity supply must be switched 
off at the starters and also at the main switchboard. Hang a notice on the switch on the main 
switchboard to show that repairs are in progress.

 

5.1 Maintenance schedule 

 

The following maintenance schedule is intended as a guideline for normal maintenance. 
However, compressor operating conditions vary widely from installation to installation and it is 
therefore important to adapt the maintenance schedule to the experience of the individual 
operator. 

 

 

Before ordering replacement parts, please read the instructions for ordering parts.
