5.11.4 On pressure reducers equipped with a pressure gauge, pressure can be seen on
the gauge itself.
Some pressure regulators do not have "push to lock", therefore simply turn the knob to adjust
the pressure.
5.12 Maintenance.
Before attempting any maintenance jobs on the compressor, make sure of the following:
Master power switch in position “0”.
Pressure switch and the control unit switches all off, in position “0”.
No pressure in the air tank.
5.12.1 Every 50 hours of duty: we advise you to dismantle the suction filter and clean the
filtering element by blowing compressed air on it (fig. 24).
5.12.2 It is recommended to replace the filter element at least once if the compressor
operates in a clean environment, but more frequently if in a dusty environment.
In the “red-head” models (fig. 25) (TR200 – TR255), the suction filter is located internally
under the conveying cover (read-head). Unscrew the three cover securing screws,
remove the cover from the guard joint, remove the filter from its seat, and begin
cleaning, blowing compressed air in opposite to normal flow direction.
In the Silent model, the filtering element can be replaced by taking off the soundproofing
cabinet and proceeding in the same way as for the AB models (fig.29A).
5.12.3 The compressor generates condensate water which accumulates in the tank.
5.12.4 The condensate in the tank must be drained at least once a week, by opening
the drain tap (fig. 26) under the tank.
5.12.5 Take care if there is compressed air inside the cylinder, and water could flow out
with considerable force. Recommended pressure: 1 – 2 bar max.
5.12.6 Condensate of compressors that are oil lubricated must not be drained into the
sewer or dispersed in the environment as it contains oil.
5.13 Oil changes and Topping up with oil.
5.13.1 The compressor is filled with synthetic oil “FIAC Oil Synthesis”.
5.13.2 We recommend a full change of oil in the pumping element within the first 100
hours of duty.
5.13.3 The soundproofing cabinet is to be taken off first in the Silent model (fig.29A).
5.13.4 Unscrew the oil drain plug on the housing cover, allow all the oil to flow out, and
re-screw the plug (fig. 27 - 28).
5.13.5 Pour oil into the upper hole of the housing cover (fig. 29 - 30) until it reaches
the level indicated on the stick (fig. 9) or indicator (fig. 11)
5.13.6 Pour oil into the upper hole of the head (fig. 30) in belt assisted units designed for
topping up in that area.
5.13.7 For the GM203 series, take the cap off and pour in 85 grams of oil directly from
the bottle (see fig. 30a).
5.13.8 Once a week: check oil level of the pumping element (fig. 11) and see if it needs
topping up.
5.13.9 For operation at ambient temperature in the range -5°C to +40°C, use synthetic
oil. The advantage of this oil is that is does not lose its characteristics either in winter or
summer.
5.13.10 DO NOT drain used oil into the sewer or dispose of it in the environment.
