OPERATION AND MAINTENANCE NOTE: 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.
INSTALLATION
After having removed the compressor from its packing (fi g. 1) and having checked its perfect integrity, making sure that it has not been
damaged during transport, proceed as follows. Fit the wheels and the rubbers on the tanks where these have not been fi tted, following the
instructions provided in fi g. 2. Also fi t the air fi lter (fi g. 3) in compressors in case this has not been fi tted.
Position the compressor on a fl at surface or one with an inclination of 10° at the most (fi g. 4), in a well-ventilated area away from
atmospheric agents and not in explosive areas. If the surface is sloping and smooth, make sure that the compressor does not move while
running, otherwise block the wheels with two wedges. If the surface consists of a shelf or the ledge of a stand, make sure that it may not
fall off by securing it appropriately. The compressor must be positioned at least 50 cm away from any walls to ensure its ideal ventilation
and effective cooling. (fi g. 5).
THIS COMPRESSOR RUNS WITHOUT OIL (fi g. 6)
OPERATIONAL INSTRUCTIONS
Transport the compressor in the correct manner without tipping it or lifting it with hooks or ropes (fi g. 7-8)
ELECTRICAL CONNECTION
The single-phase compressors are supplied complete with an electrical cable and two-pole + earth power plug. The compressor must be
connected to a power socket provided with earth connection. (fi g. 9)
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. 10), the admitted tolerance range
must remain within ± 5%.
Turn or press, depending on the type of pressure switch fi tted on the equipment, the knob situated in the upper part to «off» (fi g. 11). Put
the plug in the power socket (fi g. 9) and turn the knob to «on». Attach the rubber hose or the spiral type hose to the appropriate fi tting
situated near the pressure switch (fi g. 20). 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 roughly between the maximum and minimum value. I.e.: the compressor
stops when it reaches 10.5 bar (max. running pressure) and is automatically re-started when the pressure inside the tank falls to 8.5 bar.
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.
NOTE: The head/cylinder/delivery hose unit situated beneath the paneling may reach high temperatures therefore be careful when working
near these components and do not touch them to avoid getting burned (fi g. 12).
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. 13)
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 turning the securing ring (fi g. 13).
MAINTENANCE
Before servicing the compressor make sure that:
• the main line ON/OFF switch is on «off».
• the pressure switch or the line switch is on «off».
• there is no pressure in the air 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. 14) underneath the 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. Replace the whole connecting rod unit every 1200 hours of operation. Replace the sliding blocks and
the compression ring every 1200 hours of operation.
CLEANING THE FILTER. It is advisable to dismantle the suction fi lter every 3 months 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. This inconvenience is due to the imperfect seal of the non-return valve;
proceed as follows: (fi g. 15). Release all the pressure from the tank. 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. 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 (fi g.16). This may be due to a breakage of the valve, or a gasket. Replace inlet and exhaust
valve set.
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. 10).
• electrical extension cables with unsuitable cross-section or length are not used.
• the room in which the compressor is running is not too cold (below 0°C)
• the electric line is effi cient (plug connected correctly, magneto thermal switch, fuses not blown)
The compressor fails to stop. If the compressor fails to stop when the maximum pressure is reached, the tank safety valve will trip.
Contact the nearest authorised service center for the repairs.
WARNING
• Do not unscrew any connections with the tank when under pressure for any reason whatsoever. Always make sure that the tank is
depressurised beforehand.
• Do not drill, weld or intentionally deform the compressed air tank.
• Do not carry out any operations on the compressor before it has been unplugged from the power socket.
• The room temperature for its correct effi ciency is: 0°C +25°C (MAX 45°C).
• Do not direct jets of water or fl ammable liquids over the compressor.
• Do not place fl ammable objects near the compressor.
• When stopped temporarily during its use, turn the pressure switch or the ON/OFF switch to Off position.
• Never direct the jet of air towards people or animals (fi g. 24).
• Do not transport the compressor when the tank is pressurised.
• Be aware that some components of the compressor such as the head and delivery hoses may reach high temperatures, therefore do
not touch the to avoid getting burned (fi g. 10).
• Transport the compressor by lifting or pulling it with the appropriate grips or handles (fi g. 5 - 6).
• Children and animals must be kept away from the area in which the machine is running. If the compressor is used for painting: a) Do
not work in closed areas or near free fl ames b) Make sure that the area in which you are working has a good change of air c) Protect
nose and mouth using an appropriate mask (fi g. 18).
• Do not use the compressor if the electric cable or the plug is damaged.
• Contact the nearest authorised service centre for the replacement with an original component.
• If it is placed on a shelf or a surface that is raised off the ground, it must be secured appropriately to prevent it from tipping off when
running.
• Do not insert objects or your hands inside the safety grating to avoid physical damage and also damage to the compressor (fi g. 19).
• Do not use the compressor to threaten people or animals to avoid serious injuries. Always unplug the compressor from the power
socket when you have fi nished using it.
