10.4) COOLING RADIATOR CLEANING --
The cooling liquids of the compressor and motor are cooled by a radiator which
must therefore be kept clean to ensure that the ventilation air can easily pass through its
honeycomb flaps.
Should the flaps become clogged with dust of other particles, there is a risk of
harmful overheating of the mechanical parts of the screw compressor, seriously
jeopardizing its function and duration. It is therefore advisable to check it regularly and
clean it using compressed air or wash it using a pressurized water jet.

10.5) OIL RECOVERY NOZZLE CHECKING AND CLEANING
--
This must be undertaken in the event of any leakage of nebulized oil mixed with
compressed air, as follows (fig. 20)
:
Unscrew
the
connection
(Z)
positioned at the centre
of the tank.
Inside the connection
(Z) is a nozzle (U);
ensure that its gauged
hole is not clogged
(blow with a jet of
compressed air).
Re-assemble.
FIG. 17
WARNING:
During the regular function of the compressor it is normal to note a
certain amount of oil flow out of the transparent piping which starts from the
connection (Z), towards the compressor head.
