1. SAFETY RULES

This symbol indicates warnings to be read before using the product so as to prevent injury to the user.

Compressed air is a potentially dangerous form of energy; always take great care when using the compressor and its accessories.

Warning: the compressor may restart when power is restored following a blackout.

An ACOUSTIC PRESSURE value of 4 m. corresponds to the ACOUSTIC POWER value stated on the yellow label located on the compressor, minus 20 dB.

THINGS TO DO

• 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 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.
• Use extension cables with a maximum length of 5 meters and with crosssection of at least 2,5 mm2.
• The use of extension cables of different length and also of adapters and multiple sockets should be avoided.
• Always use the switch I/O to switch off the compressor.
• Always use the handle to move the compressor.
• When operating, the compressor must be placed on a stable, horizontal surface.

THINGS NOT TO DO

• Never direct the jet of air towards persons, animals or your body. (Always wear safety goggles to protect your eyes against flying objects that may be lifted by the jet of air).
• Never direct the jet of liquids sprayed by tools connected to the compressor towards the compressor.
• Never use the appliance with bare feet or wet hands or feet.
• Never pull the power cable to disconnect the plug from the socket or to move the compressor.
• Never leave the appliance exposed to adverse weather conditions.
• Never transport the compressor with the receiver under pressure.
• Do not weld or machine the receiver. In the case of faults or rusting, replace the entire receiver.
• Never allow inexpert persons to use the compressor. Keep children and animals at a distance 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, unless they have been given supervision or instruction concerning the use of the appliance by a person responsible for their safety.
• Children should be supervised to ensure that they do not play with the appliance.
• Do not position flammable or nylon/fabric objects closed to and/or on the compressor.
• Never clean the compressor with flammable liquids or solvents. Check that you have unplugged the compressor and clean with a damp cloth only.
• The compressor must be used only for air compression. Do not use the compressor for any other type of gas.
• The compressed air produced by the compressor cannot not be used for pharmaceutical, food or medical purposes except after particular treatments and cannot be used to fill the air bottles of scuba divers.
• Pay attention to the work being carried out. Use your common sense. Do not stand on the compressor. Do not allow the compressor to operate unattended.

THINGS YOU SHOULD KNOW

•  All the compressors are fitted with a safety valve that is tripped in the case of malfunctioning of the pressure switch in order to assure machine safety. 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.

• When fitting a tool, the flow of air in output must be switched off.
• When using compressed air, you must know and comply with the safety precautions to be adopted for each type of application (inflation, pneumatic tools, painting, washing with water-based detergents only, etc.).
• 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.
• Do not cover the air inlets on the compressor.
• Do not open or tamper with any part of the compressor. Contact an authorized Service Center.
• The compressor’s performance is guaranteed for operation between 0 and 1000 meters above the sea level.

3. START-UP AND USE

• 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 plug of the power cable in a suitable socket checking that the I/O switch located on the compressor is in the OFF «O» position.
• At this point, the compressor is ready for use.
• Operating on the I/O switch, the compressor starts, pumping air into the receiver through the delivery pipe.
• When the upper calibration value (set by the manufacturer) has been reached, the compressor stops. When air is used, the compressor restarts automatically when the lower calibration value is reached (2 bar between upper and lower).
• The pressure in the receiver can be checked on the gauge provided.
• The compressor continues to operate according to this automatic cycle until the I/O switch is turned.
• Always wait at least 10 seconds from when the compressor has been switched off before restarting this.
• All compressors are fitted with a pressure reducer (ref. 7). Operating on the knob with the tap open (turning it in a clockwise direction to increase the pressure and in a counterclockwise direction to reduce it), air pressure can be regulated so as to optimize use of pneumatic tools.
• The value set can be checked on the gauge (ref. 6).
• The set pressure can be taken from the quicklock coupling (ref. 5).
• 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.
• Always pull out the plug and drain the receiver once you have completed your work.
• This compressor has a 20 to 80 work cycle. This means that active work of compressor (pumping air into the air tank up to desired pressure level) should be 20% of total time of compressor exploatation. For example – If pumping of air tank lasts two minutes, then next pumping should take place at least 8 minutes later.

4. CLEANING AND MAINTENANCE

WARNING!

• Pull the power plug before doing any cleaning and maintenance work on
  the appliance.

WARNING!

• Wait until the compressor has completely cooled down. Risk of burns!

WARNING!

• Always depressurize the tank before carrying out any cleaning and maintenance work.

Never clean the machine and its components with solvents, flammable or toxic liquids. Us only a damp cloth making sure you have unplugged the compressor from the current outlet.
After approx. 2 hours of use, the condensate that has formed must be drained from the receiver. First of all, vent all the air using the accessory connected, as described above.
The condensation water must be drained off each day by opening the drain valve (ref. 11 – Fig. 7-9 depending on the compressor model) (on the bottom of the pressure vessel).

WARNING!

• If the water that condenses is not drained, it may corrode the receiver, reducing its capacity and impairing safety.
• As it is a contaminating product, condensate must be DISPOSED of in accordance with laws on protection of the environment and current legislation.
