5.3 AIR RECEIVER
The air receiver is tested according to official standards. Regularly
have inspections carried out in conformity with local regulations.
5.4 SAFETY VALVE
Following checks must be carried out:
– a check of the opening of the lifting gear, twice a year.
This can be done by screwing the cap of the valve anti-clockwise.
– a check of the set pressure once a year according to the local
regulations. This check cannot be done on the machine and must
be carried out on a proper test bench.
The Atlas Copco air filters are specially designed for
the application. The use of non-genuine air filters may
lead to severe damage of engine and/or compressor
element.
Never run the compressor without air filter element.
All adjustments or repairs are to be done by an
authorized representative of the valve supplier.
