TRAP

Remove dust daily.

To remove dust from the dust trap pinch the vacuator valve (6) several 
times.

ECOMMENDATIONS

New elements must also be inspected for tears or punctures before 
installation.

Discard the element (4) when damaged.

In heavy duty applications it is recommended to install a safety 
cartridge which can be ordered with part no.: 2914 9311 00

A dirty safety cartridge (3) is an indication of a mal-functioning air 
filter element. Replace the element and the safety cartridge in this case.

The safety cartridge cannot be cleaned.

RECEIVER

The air receiver is tested according to official standards. Regularly 
have inspections carried out in conformity with local regulations.

AFETY

 

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.
