5. OPERATION & MAINTENANCE
The information contained in this Instruction Manual is designed to assist you in the safe
operation and maintenance of the compressor. Some illustrations in this Instruction Manual may
show details or attachments that differ from those on your own compressor.
5.1 Installation.
5.1.1 Remove the compressor from its packing (fig.1), makes sure it is in perfect
condition, checking if it has been damaged during transport, and carry out the
following operations.
5.1.2 Fit the wheels and rubber tab on the tanks on which they are not already fitted,
observing the instructions in fig.2. In case of inflatable wheels, the maximum inflation
pressure must be of 1.6 bar (24 psi).
5.1.3 Position the compressor on a flat surface or with a maximum permissible
inclination of 10° (fig. 3), in a well aired place, protected against atmospheric agents a
and not in a place subject to explosion hazard.
5.1.4 If the surface is inclined and smooth, check if the compressor moves while in
operation – if it does, secure the wheels with two wedges.
5.1.5 If the surface is a bracket or a shelf top, make sure it cannot fall, securing it in a
suitable way.
5.1.6 To allow for good ventilation and efficient cooling, the compressor's belt guard
must be at least 100 cm from any wall (fig. 4).
5.1.7 Compressors fitted on the tank, with fixed feet, should not be rigidly secured to
the ground. In this case, we advise you to fit 4 anti-vibration supports.
5.2 Instructions for use.
5.2.1 Take care to transport the compressor correctly, do not overturn it or lift it with
hooks or ropes (fig. 5 - 6)
5.2.2 Replace the plastic plug on the guard cover (fig. 7 - 8) with the oil level stick (fig.
9) or with the relevant breather plug (fig. 10), supplied with the instructions booklet.
5.2.3 Check oil level, consulting the reference marks on the stick (fig. 9) or the oil level
inspection window (fig. 11).
5.3 Electrical connections.
5.3.1 Single-phase compressors are supplied with an electrical cable and a three pin
earth plug. The compressor must be connected to a grounded power socket (fig.12).
5.3.2 Three-phase compressors (L1+L2+L3+PE) must be installed by a specialised
technician. Three-phase compressors are supplied without a plug. Connect a plug, with
screw-on grommet and securing collar (fig.13), to the cable, consulting the table below.
