Before any maintenance work is started on the compressor, disconnect it from power supply and
protect from unauthorized and accidental starting.
-
Check if the supply voltage is lacking.
-
Any maintenance and repair work can only be carried out when the compressed air system is
completely unloaded i.e. air pressure in the system is reduced to ambient pressure.
-
Before restarting the machine, make sure that there is nobody working on the compressor and
there are no people in the vicinity.
-
Use appropriate tools for maintenance and repair work.
-
Use only original spare parts.
-
For cleaning purposes never use flammable or corrosive solvents that could damage the machine
components. Take appropriate safety measures against toxic vapours from cleaning agents.

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.
