WARNING:

The earth connection must be achieved according to the industrial safety
standards (EN 60204).
The plug of the power supply cable must not be used as a switch but
must be plugged into a power socket that is controlled by a suitable
differential switch (magneto thermal switch).

STARTING

Make sure that the mains voltage corresponds to that indicated on the
electrical data nameplate (fi g. 8), the admitted tolerance range must
remain within ± 5%.

COMPRESSOR WITH TANK (Fig. 20):

Turn or press, depending on the

type of pressure switch fi tted on the equipment, the knob situated in the
upper part to «0» (fi g. 9).
Put the plug in the power socket (fi g. 7) and turn the knob to «I». Attach
the rubber hose or the spiral type hose to the appropriate fi tting situated
near the pressure switch (fi g.25).
The compressor runs in a completely automatic manner and is controlled
by the pressure switch that stops it when the pressure inside the tank
reaches the maximum pressure and starts it again when the pressure
falls back down to the minimum level.
The difference in pressure is usually 2 bar (29 psi) roughly between the
maximum and minimum value.
I.e.: the compressor stops when it reaches 8 bar (116 psi) (max. running
pressure) and is automatically re-started when the pressure inside the
tank falls to 6 bar (87 psi).
After having connected the compressor to the electrical power supply
line, load to the maximum pressure and check the correct effi ciency of
the machine.

COMPRESSOR WITHOUT TANK (Fig. 21)

: Put the plug in the power

socket (fi g. 7). Press the starting push button situated at the side of the
compressor (fi g. 9A). This type of compressor is provided with a device
that automatically controls the maximum working pressure even if the
user is not using compressed air. The compressor automatically releases
the excess air from a valve situated on the head. The compressor
does not stop automatically. Use the ON/OFF push button to stop the
compressor.
Attach the rubber hose or the spiral type hose to the appropriate fi tting
situated at the top of the compressor, near the gear motor (fi g. 25).

NOTE:

The head/cylinder/delivery hose unit situated beneath the panelling may
reach high temperatures therefore be careful when working near these
components and do not touch them to avoid getting burned (fi g. 10).

WARNING

The electric compressors must be connected to a power socket that is
safeguarded by a suitable differential switch (magneto thermal switch).

ADJUSTING THE WORKING PRESSURE

(fi g. 11)

It is not always necessary to use the maximum working pressure, on the
contrary the pneumatic tool usually requires less pressure.
Adjust the working pressure accurately in compressors provided with
pressure regulators.
Release the knob of the pressure regulator by pulling it outwards,
adjust the pressure to the desired value by turning the knob clockwise
to increase it and anti-clockwise to decrease it. Once the ideal pressure
has been reached, block the knob by pushing it downwards (fi g. 11). In
the case of pressure regulators supplied without a gauge, the calibration
pressure may be seen on the graduated scale situated on the casing
of the actual regulator.
In the case of pressure regulators supplied with a gauge, the calibration
pressure may be seen on the actual gauge.
WARNING: Some pressure regulators do not have “push to lock”,
therefore simply turn the knob to adjust the pressure.

MAINTENANCE

Before servicing the compressor make sure that:
-  the main line ON/OFF switch is on «0».
-  the pressure switch or the line switch is on «0».
-  there is no pressure in the air tank (only for model with tank).
The compressor generates condensate that accumulates in the tank.
The condensate must be drained from the tank at least once a week
by opening the discharge tap (fi g. 12) underneath the tank (only for
model with tank).
Be careful if there is any compressed air within the cylinder as the
water could burst out with some force. Recommended pressure 1 ÷
2 bar max.

RECOMMENDED MAINTENANCE

In units F with 2 poles, replace the whole connecting rod unit every 700
hours of operation.
In units F with 4 poles, replace the whole connecting rod unit every
1500 hours of operation.
In units GMS and VS, replace the sliding blocks and the compression
ring every 1500 hours of operation.

LUBRICATING THE BEARINGS

All the bearings are lubricated with grease for life with the exception of
the roller casing fi tted on the connecting rod side of the GMS and VS
units which is to be washed with solvent and re-lubricated with “Kluber
Barrierta L 55/2” grease every 1500 hours of operation (white grease).
The grease must completely fi ll the spaces between the rollers; excess
lubricant will be expelled during the initial hours of operation.

CLEANING THE FILTER (F-ECU-GMS-VS Series-AIRCLIK-F 1)

It is advisable to dismantle the suction fi lter every 50 hours of use and to
clean the fi ltering element by blowing it with compressed air, or replace
it if the element pointed out by the arrow is clogged.

HOW TO PROCEED WHEN TRIVIAL ANOMALIES

ARE ENCOUNTERED

Loss of air from the valve underneath the pressure switch (only
model with tank)

This inconvenience is due to the imperfect seal of the non-return valve;
proceed as follows: (fi g. 13).
Release all the pressure from the tank.
Remove the panelling by unscrewing the four securing screws and lift
it. (fi g. 13-14)

(

F 1 and AIRCLIK

) .

Unscrew the hexagonal head of the valve (A)(fi g.15).
Carefully clean the small rubber disk (B) and also its seat (fi g.15).
Re-fi t everything accurately.

Loss of air (F-GMS-VS Series)

This may be due to the poor seal of one of the fi ttings. Check all the
fi ttings by wetting them with soapy water.

The compressor runs but fails to load

F-GMS-VS series compressors: (fi g.16)
- This may be due to a breakage of the valve, or a gasket (B1-B2).

Replace the damaged component.

- This may be due to a breakage of the valves (C1-C2), or a gasket

(B1-B2). Replace the damaged component (fi g.16B).

AirClik-F 1 series (fi g. 16A):
- This may be due to the breakage of the valves (C1 - C2) or of the

gasket (B1). Replace the damaged part (fi g. 16A).

The compressor fails to start

If the compressor has diffi culty in starting, make sure that:
- the mains voltage corresponds to that indicated on the data nameplate

(fi g. 8)
