• Use adequate equipment and procedures to disconnect and handle the system piping.
• Use adequate equipment to disassemble the blower components.
• Use adequate equipment and procedures to hoist the blower and its main parts.
10.1 Oil type
10.2 Oil viscosity
10.3 Recommended oils
10.4 Minimum working temperature
Check that the pour point of the oil is less than the minimum temperature that can be reached in
the ambient. If this is not the case, select an oil with a lower viscosity (a g.: ISO VG-100), or use
an oil specially made for low temperatures according to recommendations of oil producers.
