Fubag Operator's Manual

Important Safety Information

WARNING! BEFORE USING THE COMPRESSOR, READ THIS INSTRUCTION MANUAL CAREFULLY. This manual is intended for QUALIFIED AND SPECIALLY TRAINED PERSONS ONLY. Proper reading of this manual is required for use and maintenance.

This manual provides a description, safety rules, and all necessary information for the proper operation and maintenance of your FUBAG compressor. Keep this manual with the machine and refer to it for any questions concerning safe operation, maintenance, storage, and handling.

1. Safety Operation

• The compressor must be operated in a well-ventilated environment with an ambient temperature between +5°C and +40°C. Avoid areas with dust, acids, vapors, or explosive/flammable gases.
• Maintain a safety distance of at least 3 meters from the work area.
• If paint spray splashes onto the compressor guards, it indicates the compressor is too close to the work area.
• Ensure the electrical plug and socket match in shape, voltage, and frequency, complying with current regulations.
• Use extension cables with a maximum length of 5 meters and suitable cross-section. Avoid longer cables, multiple sockets, or adapters.
• Always switch off the compressor using the pressure switch button or the electric panel switch (if equipped). Never pull the plug to switch off to prevent automatic restart with pressure in the head.
• Always use the designated handle to move the compressor.
• Place the compressor on a stable, horizontal surface for correct lubrication.
• Position the compressor at least 50 cm from walls to ensure optimal fresh air circulation and cooling.

The acoustic pressure value measured at 4 meters in free field corresponds to the acoustic power value stated on the yellow label, minus 20 dB.

Prohibitions (Not to Do)

• Never direct the air jet towards people, animals, or yourself. Always wear safety goggles ? to protect your eyes from flying objects.
• Never direct sprayed liquids from connected tools towards the compressor.
• Never operate the appliance barefoot or with wet hands or feet.
• Never pull the power cable to unplug or move the compressor.
• Never expose the appliance to adverse weather conditions (rain, sun, fog, snow).
• Never transport the compressor with the reservoir pressurized.
• Never weld or machine the reservoir. Replace it if defects or corrosion are found.
• Never allow inexpert persons to use the compressor. Keep children and animals away from the work area.
• Never place flammable or nylon/fabric articles near or on the compressor.
• Never clean the compressor with flammable liquids or solvents. Use only a damp cloth after unplugging the unit.
• The compressor is designed only for compressing air. Do not use it for other gases.
• Compressed air is not suitable for pharmaceutical, food, or hospital purposes without specific treatments. It is not suitable for filling scuba diving air bottles.

Cautionary Notes

• To prevent electric motor overheating, this compressor is designed for intermittent operation (e.g., S3-25 means 2.5 minutes ON and 7.5 minutes OFF). Thermal cutout will automatically shut off power if overheating occurs.
• For easier restart, after operations, set the pressure switch button to OFF, then ON again (see figures 2-3-4).
• Press the reset button on the motor's terminal box (see figure 3).
• The pressure switch may have a delayed closing air vent valve for easier start-up. A brief air jet from this valve when the reservoir is empty is normal.
• A safety valve is fitted for protection against pressure switch failure.
• When connecting air-powered tools, ensure the air flow from the hose is interrupted.
• Using compressed air for inflation, tools, painting, or washing requires knowledge of and compliance with relevant safety rules for each application.

2. Technical Specifications

The manufacturer reserves the right to change the manual's content or function without prior notification.

3. Start-up and Use

1. Fit the wheels and foot (or caster wheel) as per packaging instructions. For fixed feet, assemble the front bracket or vibration-dampers. Verify that the rating data match the electrical system's characteristics (voltage and power).
2. Check that the compressor plate data correspond with the actual electrical system specifications. A variation of ±10% from the rated value is permissible.
3. Insert the power plug into a suitable socket, ensuring the pressure switch button is in the "O" (OFF) position (see figure 6: Electrical socket and plug insertion).
4. Check the oil level using the dipstick (see figures 7a-7b-7c: Oil dipstick and level markings) or the sight glass (see figure 7d: Oil level sight glass). Top up if necessary.
5. The compressor is now ready for use.
6. Turn the pressure switch to the "ON" position (see figure 3: Hand operating a switch). The compressor will start and pump air into the reservoir via the delivery hose.
7. The absence of pressure in the head facilitates subsequent restart. When air is used, the compressor automatically restarts when the lower calibration value is reached (approx. 2 bar difference between upper and lower). The reservoir pressure can be checked on the gauge (see figure 8: Compressor gauges).
8. The compressor operates automatically in this work cycle until the pressure switch is modified. To restart after switching off, wait at least 10 seconds.
9. Air pressure can be regulated using the knob on the pressure regulator. Pull the knob up, turn clockwise to increase pressure, and counterclockwise to decrease it (see figures 9a-9d: Pressure regulator adjustment). Push the knob down to lock the set value.
10. Ensure the air consumption and maximum working pressure of the pneumatic tool are compatible with the set pressure and the compressor's air supply.
11. When finished, stop the machine, unplug it (see figure 10: Unplugging the compressor), and empty the reservoir (see figure 11: Draining condensate).

4. Maintenance

The service life of the machine depends on the quality of maintenance.

• BEFORE ANY OPERATION: ALWAYS PULL OUT THE PLUG AND COMPLETELY DRAIN THE RECEIVER (see figures 10-11).
• Tighten the head tie-bolts at start-up and after the first hour of work (torque 10 Nm = 1.02 Kgm).
• After loosening safety screws (see figure 12a: Loosening safety screws), clean the intake filter based on the working environment, at least every 100 hours (see figures 12b-12c: Cleaning/replacing intake filter). Replace the filter element if necessary (a clogged filter reduces performance and increases wear).
• Replace the oil after the first 100 hours of operation and every 300 hours thereafter (see figures 13a-13c: Oil replacement). Check the oil level regularly.
• Periodically (or after more than one hour of operation), drain the condensate that forms inside the receiver (see figure 11: Draining condensate) due to air humidity. This prevents receiver corrosion and maintains capacity.

Maintenance Schedule

* The check must be performed before the first compressor start-up.

Spent oil and condensate must be disposed of in compliance with environmental protection regulations.

5. Troubleshooting

For issues with electrical components (cables, motor, pressure switch, electric panel, etc.), request assistance from a qualified electrician.

For all other issues, repairs must be carried out by authorized Service Centers using original parts. Tampering with the machine may compromise safety and void the warranty.

6. Warranty

The warranty covers defects in materials and components, not natural wear and tear or maintenance work.

Warranty is valid only for machines returned in original factory packaging, complete, with the instruction manual, warranty card (with fixed sales date, shop stamp, factory serial number), and original sales/cash receipts. Within the warranty period, the service center will repair detected production defects free of charge.

The manufacturer disclaims warranty and legal responsibility for issues arising from non-observance of the instruction manual, unqualified disassembly, repair, or maintenance. The manufacturer is not responsible for any injuries or damages caused.
