In this manual and/or on the machine the following symbols are used:

2 GENERAL POWER TOOL SAFETY WARNINGS

Read all safety warnings and all instructions. Failure to follow all warnings and instructions may result in electric shock, fire and/or serious injury. Save all warnings and instructions for future reference. The term "power tool" in the warnings refers to your mains operated (corded) power tool or battery operated (cordless) power tool.

2.1 Work area

 Keep work area clean and well lit. Cluttered and dark areas invite accidents.  Do not operate power tools in explosive atmospheres, such as in the presence of

flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.

 Keep children and bystanders away while operating a power tool. Distractions can cause

you to lose control.

2.2 Electrical safety

Always check that the power supply corresponds to the voltage on the rating plate.

 Power tool plugs must match the outlet. Never modify the plug in any way. Do not use

any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.

 Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges

and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.

 Do not expose power tools to rain or wet conditions. Water entering a power tool will

increase the risk of electric shock.

 Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power

POWXQ8125 EN

tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.

 When operating a power tool outdoors, use an extension cord suitable for outdoor use.

Use of a cord suitable for outdoor use reduces the risk of electric shock.

 If operating a power tool in a damp location is unavoidable, use a residual current device

(RCD) protected supply. Use of an RCD reduces the risk of electric shock.

2.3 Personal safety

 Stay alert, watch what you are doing and use common sense when operating a power

tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.

 Use safety equipment. Always wear eye protection. Safety equipment such as dust mask,

non-skid safety shoes, hard hat, or hearing protection used whenever conditions require will reduce personal injuries.

 Avoid accidental starting. Ensure the switch is in the off position before plugging in.

Carrying power tools with your finger on the switch or plugging in power tools that have the switch on invites accidents.

 Remove any adjusting key or wrench before turning the power tool on. A wrench or a key

left attached to a rotating part of the power tool may result in personal injury.

 Do not overreach. Keep proper footing and balance at all times. This enables better

control of the power tool in unexpected situations.

 Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and

gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.

 If devices are provided for the connection of dust extraction and collection facilities,

ensure these are connected and properly used. Use of these devices can reduce dust related hazards.

2.4 Power tool use and care

 Do not force the power tool. Use the correct power tool for your application. The correct

power tool will do the job better and safer at the rate for which it was designed.

 Do not use the power tool if the switch does not turn it on and off. Any power tool that

cannot be controlled with the switch is dangerous and must be repaired.

 Disconnect the plug from the power source before making any adjustments, changing

accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.

 Store idle power tools out of the reach of children and do not allow persons unfamiliar with

the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.

 Maintain power tools. Check for misalignment or sticking of moving parts, breakage of

parts and any other condition that may affect the power tool’s operation. If damaged, have

the power tool repaired before use. Many accidents are caused by poorly maintained power tools.

 Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting

edges are less likely to stick and are easier to control.

 Use the power tool, accessories and tool bits etc., in accordance with these instructions

and in the manner intended for the particular type of power tool, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from intended could lead to a hazardous situation.

POWXQ8125 EN

2.5 Service

 Have your power tool serviced by a qualified repair person using only identical

replacement parts. This will ensure that the safety of the power tool is maintained.

3 PRECAUTIONS

3.1 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.

 For three-phase versions have the plug fitted by a qualified electrician according to local

regulations. The first time you start the compressor, check that the direction of rotation is correct and matches that indicated by the arrow on the conveyor (Fig. 1, the air must be conveyed towards the head of the compressor).

 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  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.

3.2 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.

 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.

3.3 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 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 (figures 1a-1b).

 On single-phase versions, press the reset button on the terminal box of the motor (fig. 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 (figures 3a-3b-3c).

 The single-phase versions 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 (fig. 4).

 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.

4 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 (figures 5a-5b-5c-5d).

 For the 3-phase versions, connect the plug to a panel protected by suitable fuses.  For the versions fitted 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 qualified personnel.

 Check the oil level using the sight glass and if necessary unscrew the vent plug and top

up. (figures 6a-6b).

 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, (figures 5a-5b-5c-5d), the compressor starts, pumping air in the reservoir through the delivery hose.

 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 (fig. 4).

of the switch of the pressure switch (or of the selector of the electric panel) figures 5a-5b5c-5d) is modified. 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 fitted with a pressure reducer (in the versions

with fixed 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) (fig. 7). 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, fig. 8).  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.

6 MAINTENANCE

 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 (fig.

9). The check must be carried out prior to the first compressor starting.

 Clean the suction filter according to the type of environment and in any case at least every

100 hours. If necessary, replace the filter (a clogged filter impairs efficiency while an inefficient filter causes harsher wear on the compressor (figures 10a - 10b).

 Change the oil after the first 100 hours of operation and subsequently every 300 hours.

Fault

Top up or change oil (figures 16a16b-16c).

Check the oil level periodically.

 Use API CC/SC SAE 40. (For cold climates, API CC/SC 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 (fig. 11) making sure that there are no leaks during use.

Once a week, check the oil level to assure lubrication in time (fig. 6a).

 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 (fig. 12) 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 flexion (f) of around 1 cm

(fig. 13).
