WARNING! BEFORE USING THE COMPRESSOR READ THE INSTRUCTION MANUAL CAREFULLY! FOR QUALIFIED AND SPECIALLY TRAINED PERSONS ONLY AFTER PROPER READING OF THIS MANUAL IS ALLOWED TO USE AND TO MAINTAIN THIS COMPRESSOR.
The detailed description, safety rules and all required information necessary for proper operation and maintenance of FUBAG compressor are provided below. Keep this instruction manual by machine and refer to it by any doubts concerning safety operation, maintenance storage and handling of FUBAG compressor.
1. Safety operation
– The compressor must be used in a suitable environment (well ventilated with
an ambient temperature of between +5°C and +40°C) and never in places affected
by dust, acids, vapors, explosive or flammable gases.
– Always maintain a safety distance of at least 3 meters between the
compressor and the work area.
– Any coloring of the guards of the compressor during painting operations
indicates that the distance is too short.
– Insert the plug of the electric cable in a socket of suitable shape, voltage
and frequency complying with current regulations.
– Use extension cables with a maximum length of 5 meters and of suitable
cross-section.
– The use of extension cables of different length and also of adapters and
multiple sockets should be avoided.
– Always use the switch of the pressure switch to switch off the compressor or
use the switch of the electric panel for models equipped with this. Never
switch off the compressor by pulling out the plug in order to avoid restart
with pressure in the head.
– Always use the handle to move the compressor.
– When operating, the compressor must be placed on a stable, horizontal
surface to guarantee correct lubrication.
– Position the compressor at least 50 cm from the wall to permit optimal
circulation of fresh air and to guarantee correct cooling.
The acoustic pressure’s value measured at 4 m in free field corresponds to the acoustic power’s value stated on the yellow label located on the compressor, minus 20 dB.
Not to do:
– Never direct the jet of air towards persons, animals or your body. (Always
wear safety goggles to protect your eyes from flying objects that may be
lifted by the jet).
– Never direct the jet of liquids sprayed by tools connected to the compressor
towards the compressor.
– Never use the appliance in your bare feet or with wet hands or feet.
– Never pull the power cable to pull the plug out of the socket or to move the
compressor.
– Never leave the appliance exposed to adverse weather conditions (rain, sun,
fog, snow).
– Never transport the compressor with the reservoir pressurized
– Never weld or machine the reservoir. In the case of faults or corrosion,
replace it completely.
– Never allow inexpert persons to use the compressor. Keep children and
animals away from the work area.
– Never position flammable or nylon or fabric articles close to and/or on the
compressor.
– Never clean the compressor with flammable liquids or solvents. Clean with a
damp cloth only, after making sure that you have unplugged the compressor.
– The compressor is designed only to compress air and must not be used for any
other type of gas.
– The compressed air produced by the compressor cannot not be used for
pharmaceutical, food or hospital purposes except after particular treatments.
It is not suitable for filling the air bottles of scuba divers.
Caution:
– To avoid overheating of the electric motor, this compressor is designed for
intermittent operation as indicated on the data plate (for example, S3-25
means 2,5 minutes ON and 7,5 minutes OFF). In the case of overheating, the
thermal cutout of the motor trips, automatically cutting off the power when
the temperature is too high due to excess current takeoff.
– To facilitate machine restart, it is important not only to carry out the
operations indicated but also to set the button of the pressure switch,
returning this to the OFF position and then ON again (fig. 2-3-4).
– Press the reset button on the terminal box of the motor (fig. 3).
– Are fitted with a pressure switch equipped with a delayed closing air vent
valve (or with a valve located on the check valve) that facilitates motor
start-up; therefore a few-second jet of air from this, with the reservoir
empty, is to be considered normal.
– To guarantee machine safety, all the compressors are fitted with a safety
valve that is activated in the case of failure of the pressure switch.
– When connecting an air-powered tool to a hose of compressed air supplied by
the compressor, interruption of the flow of air from the hose is compulsory.
– Use of the compressed air for the various purposes envisaged (inflation,
air-powered tools, painting, washing with water-based detergents only, etc.)
requires knowledge of and compliance with the rules established for each
individual use.

3. Start-up and use
– Fit the wheels and foot (or the caster wheel for models that are fitted with
this) according to the instructions provided in the packaging. For versions
with fixed feet, assemble the front bracket kit or the vibration-dampers if
furnished. Check that the rating data match the effective characteristics of
the system (voltage and power).
– Check for correspondence between the compressor plate data with the actual
specifications of the electrical system. A variation of ± 10% with respect of
the rated value is allowed.
– Insert the power plug in a suitable socket checking that the button of the
pressure switch located on the compressor is in the “O” (OFF) position
(fig.6).
– Check the oil level using the rod included in the oil fuel plug (fig. 7a-7b-
7c) or the sight glass (fig. 7d), and if necessary top up.
– At this point, the compressor is ready for use.
– Operating on the switch of the pressure switch (fig. 3), the compressor
starts, pumping air in the
reservoir through the delivery hose.
– The absence of pressure in the head facilitates subsequent restart. When air
is used, the compressor restarts automatically when the lower calibration
value is reached (approx. 2 bar between upper and lower). The pressure inside
the reservoir can be checked on the gauge provided (fig. 8).
– The compressor continues to operate automatically with this work cycle until
the position of the switch of the pressure switch is modified. To use the
compressor again, wait at least 10 seconds after this has been switched off
before restarting.
– Air pressure can be regulated in order to optimize use of air-powered tools
operating on the knob with the valve open (pulling it up and turning it in a
clockwise direction to increase pressure and counterclockwise to reduce this)
(fig. 9a-9b-9c-9d). Once you have set the value required, push the knob down
to lock it.
– Please check that the air consumption and the maximum working pressure of
the pneumatic tool to be used are compatible with the pressure set on the
pressure regulator and with the amount of air supplied by the compressor.
– When you have finished working, stop the machine, pull out the plug and
empty the reservoir (fig. 10-11).
4. Maintenance
– The service life of the machine depends on maintenance quality.
– BEFORE CARRYING OUT ANY OPERATION, ALWAYS PULL OUT THE PLUG AND DRAIN THE
RECEIVER COMPLETELY (fig. 10-11)
– Tighten the tie-bolts of the head at start-up and after the first hour of
work (torque 10 Nm = 1.02 Kgm).
– After loosening any safety screws (fig. 12a), clean the intake filter
according to the type of working environment and at least every 100 hours
(fig. 12b-12c). If necessary, replace the filter element (clogging of the
filter reduces compressor performance and an inefficient filter causes
increased wear).
– Replace the oil after the first 100 hours of operation and every 300 hours
subsequently (fig. 13a13b-13c). Remember to check the oil level at regular
intervals.
– Periodically (or after working with the compressor for more than an hour),
drain the condensate that forms inside the receiver (fig. 11) due to the
humidity in the air. This protects the receiver from corrosion and does not
restrict its capacity.

5. Troubleshooting
Request the assistance of a qualified electrician for operations on electric components (cables, motor, pressure switch, electric panel, etc).
FAULT | CAUSE | REMEDY |
---|---|---|
Leakage of air from the valve of the pressure switch with the compressor off. |
Check valve that, due to wear or dirt on the seal, does not perform its
function correctly.| Unscrew the hexagonal head of the check valve, clean the
valve seat and the special rubber disk (replace if worn). Reassemble and
tighten carefully (figures 14a-14b ).
Reduction of performance. Frequent start-up. Low pressure values.| Excessive
performance request, check for any leaks from the couplings and/or pipes.
Intake filter may be clogged.| Replace the seals of the fitting, clean or
replace the filter.
The compressor stops and restarts automatically after a few minutes.| Tripping
of the thermal cutout due to overheating of the motor.| Clean the air ducts in
the conveyor. Ventilate the work area. Reset the thermal cutout. On lubricated
check oil level and quality.
After a few attempts to restart, the compressor.| Tripping of the thermal
cutout due to overheating of the motor.| Activate the on/off switch. Ventilate
the work area. Wait a few minutes. The compressor will restart independently.
Remove any power cable extensions.
The compressor does not stop and the safety valve is tripped.| Irregular functioning of the compressor or breakage of the pressure switch.| Remove the plug and contact the Service Center.
Any other type of operation must be carried out by authorized Service Centers, requesting original parts. Tampering with the machine may impair its safety and in any case make the warranty null and void.
