These compressors are not suitable for outdoor use. These compressors have been designed for use in professional applications.

• The compressor must be used in a suitable environment (well ventilated with an ambient temperature between +5°C and +40°C, and relative humidity max 50% at 40°C) and never in places affected by dust, acids, vapors, explosive or ammable gases.

• Always maintain a safety distance of at least 4 meters between the compressor and the work area.

• Any coloring of the belt 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.

• For 3-phase versions, have the plug tted by a qualied electrician according to local regulations. When starting the compressor for the rst time, check the correct direction of rotation and that this matches the direction indicated by the arrow on the belt guard (versions with plastic protection) or on the motor (versions with metal protection).

• 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.

• Never direct the jet of air towards persons, animals or your body. (Always wear safety goggles to protect your eyes from ying 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 inexperienced persons to use the compressor. Keep children and animals away from the work area.

• This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge.

• Children should be supervised to ensure that they do not play with the appliance.

• Never position ammable or nylon or fabric articles close to and/or on the compressor.

• Never clean the compressor with ammable 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 lling the air bottles of scuba divers.

• Never use the compressor without guards (belt guard) and never touch moving parts.

THINGS YOU SHOULD KNOW

• To avoid overheating of the electric motor, this compressor is designed for intermittent operation as indicated on the dataplate (for example, S3- 50 means 5 minutes ON and 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 take-off.

• 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 (gures 1a-1b).

• On single-phase versions, press the reset button on the terminal box of the motor (g. 2).

• On 3-phase versions, operate manually on the button of the pressure switch, returning this to the ON position, or press the button of the thermal cutout inside the box of the electric panel (gures 3a-3b-3c).

• The single-phase versions are tted 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 tted with a safety valve that is activated in the case of failure of the pressure switch (g. 4a-4b).

• All two-stage compressors are equipped with safety valves on the air delivery manifold to the reservoir and on the connection hose between the low and high pressure located on the head. These are activated in the case of malfunctioning (g. 5). The safety valve is set to avoid over-pressurization of the air tanks. This valve is factory pre-set and will not function unless tank pressure reaches this pressure. Do not attempt to adjust or eliminate this safety device. Any adjustments to this valve could cause serious injury. If this device requires service or maintenance, see an Authorized Service Center.

• The red notch on the pressure gauge refers to the maximum operating pressure of the tank. It does not refer to the adjusted pressure.

• When connecting an air-powered tool to a hose of compressed air supplied by the compressor, interruption of the ow of air from the hose is compulsory.

• Use of the compressed air for the various purposes envisaged (ination, air- powered tools, painting, washing with water-based detergents only, etc.) requires knowledge of and compliance with the rules established for each individual use.

• Please check that the air consumption and the maximum working pressure of the pneumatic tool and connection pipes (with the compressor) to be used, are compatible with the pressure set on the pressure regulator and with the amount of air supplied by the compressor.

• Supply hoses at pressures above 7 bar should be equipped with a safety cable (e.g. a wire rope).

• The compressor's performance is guaranteed for operation between 0 and 1000 meters above the sea level.

• The compressor is subject to conditioned connection with maximum impedance (Zmax) shown on the motor data plate.

• Fit the supplied wheels as shown in gures 19 and 20. For versions with xed feet, assemble the vibration-dampers if furnished (g. 21).

• Check for correspondence between the compressor plate data with the actual specications 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 (gures 6a-6b-6c-6d).

• For the 3-phase versions, connect the plug to a panel protected by suitable fuses.

• For the versions tted with electric panel (“Tandem” control units or delta/star starters) have installation and connections (to the motor, to the pressure switch and to the electrovalve if any) carried out by qualied personnel.

• Check the oil level using the sight glass and if necessary unscrew the vent plug and top up. (gures 7a-7b).

• At this point, the compressor is ready for use.

• Operating on the switch of the pressure switch (or the selector for versions with electric panel), (gures 6a-6b-6c-6d), the compressor starts, pumping air in the reservoir through the delivery hose. On 2-stage versions, air is sucked into the so-called low pressure cylinder liner and precompressed. It is then routed, through the recirculation hose, into the so-called high pressure liner and then into the reservoir. With this work cycle, it is possible to reach higher pressure, with availability of air at 11 bar (15 bar for special machines).

• On reaching maximum operating pressure (factory-set during testing), the compressor stops, venting the excess air present in the head and in the delivery hose through a valve located under the pressure switch (in delta/star versions, through an electrovalve that is activated when the motor stops).

• 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 (g. 4a-4b).

• The compressor continues to operate automatically with this work cycle until the position of the switch of the pressure switch (or of the selector of the electric panel) (gures 6a-6b-6c-6d) is modied. To use the compressor again, wait at least 10 seconds after this has been switched off before restarting.

• In the versions with electric panel, the pressure switch must always be aligned with the I (ON) position.

• In tandem versions, the control unit provided permits use of only one of the two compressor groups (if necessary alternatively) or of both at the same time according to requirements. In this second case, start-up will be differentiated slightly to avoid excessively high current take-off at start-up (timed starting).

• Only the wheel-mounted compressors are tted with a pressure reducer (in the versions with xed feet, it is usually installed on the use line). 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) (g. 8). Once you have set the value required, push the knob down to lock it.

• The value set can be checked on the gauge (for versions equipped with this, g. 9).

• 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 nished working, stop the machine, pull out the plug and empty the reservoir.

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

• PRIOR TO ANY OPERATION SET THE PRESSURE SWITCH TO THE OFF POSITION, PULL OUT THE PLUG AND COMPLETELY DRAIN THE RESERVOIR.

• Check that all screws (in particular those of the head of the unit) are tightly drawn up (g. 10). The control must be performed before the rst start-up of the compressor and subsequently before the rst intensive use in order to restore the correct closing torque value modied as a result of heat expansion.

TABLE 1 – TIGHTENING OF HEAD TENSION RODS

• Clean the suction lter according to the type of environment and in any case at least every 100 hours. If necessary, replace the lter (a clogged lter impairs efciency while an inefcient lter causes harsher wear on the compressor (gures 11a - 11b-11c-11d).

• Change the oil after the rst 100 hours of operation and subsequently every 300 hours. Check the oil level periodically.

• Use SAE 40. (For cold climates, SAE 20 is recommended). Never mix different grade oils. If the oil changes color (whitish = presence of water; dark = overheated), it is good practice to replace the oil immediately.

• After topping up, tighten the plug (g. 12) making sure that there are no leaks during use. Once a week, check the oil level to assure lubrication in time (g. 7a).

• Periodically (or after completing work if for more than an hour), drain the condensate that forms inside the reservoir due to the humidity in the air (g. 13a-13b) in order to protect the reservoir from rust and so as not to restrict its capacity.

• Periodically, check the tension of the belts which must have a exion (f) of around 1 cm (g. 14). TABLE 2 – MAINTENANCE FUNCTION AFTER THE FIRST 100 HOURS EVERY 100 HOURS EVERY 300 HOURS Cleaning of intake filter and/ or substitution of filtering element

Tightening of head tension rods The check must be carried out prior to the rst compressor starting. Draining tank condensate Periodically and at the end of work Checking the tension of the belts Periodically

• Spent oil and condensate MUST BE DISPOSED OF in compliance with protection of the environment and current legislation.

Pull the mains plug out of the socket and vent the appliance and all connected pneumatic tools. Switch off the compressor and make sure that it is secured in such a way that it cannot be started up again by any unauthorized person.

The compressor must be disposed in conformity with the methods provided for by local regulations.

6. WARRANTY AND REPAIR

In the event of defective goods or requirements for spare parts, kindly contact the sales point where you made your purchase.

Request the assistance of a qualied electrician for operations on electric components (cables, motor, pressure switch, electric panel, etc). Fault Cause Remedy Air leak from the valve of the pressure switch. Check valve does not perform its function correctly due to wear or dirt on the seal. Unscrew the hex-shaped head of the check valve, clean the housing and the special rubber disk (replace if worn). Re-assembler and tighten carefully (gures 15a-15b). Condensate drainage cock open. Close the Condensate drainage cock. Rilsan hose not inserted correctly in pressure switch. Insert the Rilsan hose correctly inside the pressure switch (g. 16). Reduction of efciency, frequent start-up. Low pressure values. Excessively high consumption. Decrease the demand of compressed air. Leaks from joints and/or pipes. Change gaskets. Clogging of the suction lter. Clean/replace the suction lter (gures 11a-11b-11c-11d). Slipping of the belt. Check belt tension (g. 14). The motor and/or the compressor overheat irregularly. Insufcient ventilation. Improve ambient conditions. Closing of air ducts. Check and if necessary clean the air lter. Insufcient lubrication. Top up or change oil (gures 17a-17b-17c). After an attempt to start the compressor, it stops due to tripping of the thermal cutout caused by forcing of the motor. Start-up with head of the compressor charged. Release the compressor head by using the pressure switch push button. Low temperature. Improve ambient conditions. Voltage too low. Check that the mains voltage matches that of the dataplate. Eliminate any extensions. Incorrect or insufcient lubrication. Check level, top up and if necessary change the oil. Inefcient electrovalve. Call the Service Center. During operation, the compressor stops for no apparent reason. Tripping of the thermal cutout of the motor. Check level oil. Single-stage, mono-phase versions: operate on the button of the pressure switch returning this to the OFF position (g. 1a). Reset the thermal cutout (g. 2) and restart (gures 1b). If the fault persists, call the Service Center. Versions with delta-star starter: operate on the button of the thermal cutout located inside the box of the electric panel (g. 3c) and restart (g. 6d).
