the wall reaches the minimum value indicated in the tank certification (part of the documentation provided with the unit).
• The life-span of the air tank depends mainly on the operating environment. Avoid installing the compressor in a dirty and corrosive environment as this can
greatly reduce the life-span of the tank.
G
• Do not anchor the tank or its components directly onto the ground or onto rigid structures. Assemble anti-vibration pads on the tank to prevent faults due to
excessive stress caused by vibration of the tank during use.
B
• Use the tank observing the temperature and pressure limits on the data plate and in the test report.
• Do not carry out welding, drilling or machining to modify the machine in any way.
MAINTENANCE
4
• BEFORE CARRYING OUT ANY MAINTENANCE, UNPLUG THE MACHINE, EMPTY THE ENTIRE TANK AND ALLOW THE MACHINE TO COOL DOWN
