WARNING: MANUAL CAREFULLY! QUALIFIED AND SPECIALLY TRAINED PERSONS ONLY AFTER PROPER READING OF THIS MANUAL IS ALLOWED TO USE AND MAINTAIN THIS COMPRESSOR. BEFORE USING THE COMPRESSOR READ THE INSTRUCTION.
The detailed description, safety rules and all required information necessary for the proper operation and maintenance of the 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 the FUBAG compressor.
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.
WARNING: 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 can 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 (forexample, S3-25 means 2,5 minutesONand\ 7,5 minutes OFF). In the case of overheating, the thermal cutout of the motor trips automatically cuts 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.1- 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 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 user.
Technical specifications
The manufacturer reserves the right to make the manual’s content or function change without any preliminary notification of the users.
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 ), 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 switches is modified. lo 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)
Maintenance
- The service life of the machine depends on maintaining 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. 13a- 13b-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 due to the humidity in the air. This protects the receiver from corrosion and does not restrict its capacity.
Spent oil and condensate must be disposed of in compliance with the protection of the environment and current legislation.
Troubleshooting
Request the assistance of a qualified electrician for operations on electric components (cables, motor, pressure switch, electric panel, etc).
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.
Warranty
Warranty refers to defects of materials and components and does not refer to components subject to natural wear and maintenance work. Only machines cleaned from dust and dirt in original factory packing fully completed, provided with an instruction manual, warranty card with fixed sales date with a shop stamp factory serial number, and originals of sales and ware receipt issued by salesman are subjects of warranty. Within the warranty period the service center eliminates free of charge all detected production defects. The manufacturer disclaims warranty and legal responsibilities if nonobservance of the instruction manual by the user, unqualified disassembling repair or maintenance of the machine as well does not bear responsibility for caused injury to persons or damages.
