- Upon finishing the maintenance work, make sure no tools or other objects are left on or
inside the compressor.
- Before restarting the machine after maintenance, check operating pressures,
temperatures, time settings, and test the switching and control equipment for proper
functioning.
- Protect the motor, air filters, electric components, control equipment etc. from penetration
of moisture.
- Do not perform any welding or any other works generating heat close to the oil system.
- Under no circumstances should the noise absorbing material be removed or relocated.
The manufacturer accepts no responsibility for any damage and personal injuries resulting
from failure to observe the present safety rules or from carelessness during operation, work
and maintenance, even in circumstances not expressly mentioned in this Operating and
Maintenance Manual.
In order to ensure fault-free operation of the compressor, observe the following instructions
relating to periodic inspections and maintenance operations.
8.2. Maintenance and inspections
8.2.1. Maintenance at the beginning of the compressor use and after oil and V-
belts (where applicable) change
After 2 hours of
operation
- Check the oil level in the oil tank and top it up, if
necessary.
- Check and, if necessary, tension the V-belts (where
applicable).
After 2 days of
operation
- Check the oil level in the oil tank and top it up, if
necessary.
- Check and, if necessary, tension the V-belts (where
applicable).
After one week of
operation
- Check and, if necessary, tension the V-belts (where
applicable).
8.2.2 Daily maintenance
- Visually inspect the condition of the pneumatic and oil conduit connections.
- Check the air overpressure gauge and temperature indicator for correct readings.
- Check the compressor behaviour during operation for unusual symptoms such as
excessive noise and vibration.
- Check the oil level.
- Check the condition and tension of the V-belts(where applicable).
- Check fastening of the covers and guards for loose screw joints.
8.2.3 Periodic maintenance
Every 100 hours of the compressor operation or after a longer downtime, you must:
- Check the oil level and top it up, if necessary.
- Check the tank for the presence of condensate and remove condensate, if necessary.
Every 1000 hours, you must:
- Check the air filter for dirt and replace its cartridge, if necessary (in case of dusty
environments it is recommended to clean and replace the filter cartridge more often).
- Check the condition and tension of the V-belts(tension them if necessary) or the condition
of the elastic coupling.
- Clean the air and oil cooler ribs if necessary.
- Check the safety valve for correct operation.
- Clean the condensate drain filter and condenser in the refrigerant dryer.
