• Pull the power supply plug before starting repair, inspection, maintenance, or cleaning work, or before replacing any parts.
• Inadvertent starting. Do not transport the compressor while it is connected to the electric power. Make sure the switch is in OFF position before you plug in the electric cable.
• Store the compressor correctly. When the compressor is not used, it must be stored in a dry place protected from weather conditions.
• Working area. Make sure the work place is clean and well aerated. Put away any tools that are not needed. Do not use the compressor together with inflammable liquids or gases – risk of electric shock. Protect the compressor from rain and do not use it in humid or wet conditions. Since sparks can emanate from the compressor during work, it must be kept away from lacquers, gasoline, chemicals, glues, and other inflammable or explosive materials.
• Keep children away. Children, third persons or animals may not get in touch with the compressor. Unauthorized persons must observe a safety distance from the working zone.
• Working clothes. Wear close fitting clothes. Take off jewels as they could get caught in moving machine parts. Protect long hair by a net or cap.
• Do not misuse the electric cable. Do not remove the plug from the socket by pulling the cable. Keep the cable away from heat, oil and surfaces with sharp edges. Do not step on the cable, and do not squeeze it by putting heavy weights on it.
• Carefully service the compressor.

Regularly check the electric cable. In case of a defect, have it repaired or replaced by an authorized service station. Carefully inspect the compressor from outside and have any defects repaired by a service station.

• Attention. Keep your mind at what you are doing. Use your common sense. Never work with the compressor when you are tired, or under influence of alcohol, drugs, or medicines causing drowsiness.
• Check the compressor for any defective parts or loss of air. Before you use the compressor again, check the correct position of the moving parts, cables, manometer, compressed air connections and all other parts important for the correct operation. Defective components must be

repaired or replaced by an authorized service station, observing the instructions given in this manual. The compressor may not be used with the pressure control valve defective.

• The compressor may only be used for the purposes specified in this operating manual. Do not allow children or inexperienced persons work with the compressor. The compressor is a machine generating compressed air. Use it according to the instructions given in this manual. Any other use exceeds authorization. The manufacturer is not responsible for any damages resulting from unauthorized use; risk is the sole responsibility of the operator.
• Keep the venting grids clean, especially when working in dirty conditions.
• Use the compressor at the rated voltage indicated on the model plate with the electrical data. The admissible tolerance range is +/- 5 %.
• Never use a defective compressor. If, during operation, you note a strange noise, excessive vibrations or any defects, switch it off immediately, check its good working order or contact your authorized service station.
• Only use original spare parts. The use of non-original spare parts renders the warranty invalid, and it can cause a malfunction of the compressor. Do not make any arbitrary modification on the compressor. Have repairs done by an authorized service station.
• Put the switch to OFF position when the compressor is not used. Put the switch to „0“ (OFF) to interrupt the power supply.
• Do not touch the hot parts of the compressor.
• Do not switch off the compressor by pulling the electric cable.
• Compressed air circuit. Use compressed air hoses and tools made for a higher (or identical pressure) than the maximum operating pressure of the compressor.

Additional safety notes for air compressors

Warning: Before connecting the compressor to the electric power (main switch on machine, socket, etc.), make sure the power supply corresponds with the data on the model plate. A higher mains voltage can cause serious injuries and damage the machine. Do not connect the machine in case of doubt. If the mains voltage is too low, the motor can get damaged.

Always pull the power supply plug before doing any maintenance or adjustment work, including changing the oil.

1 Never try to remove a part from the compressor while it is pressurized.
2 Never try to remove an electrical part while the compressor is connected to the mains supply. Switch the machine off and pull the power supply plug.
3 Do not adjust the safety valve.

4 Do not use an electrical extension cable.
5 If the drain plug underneath the switch cover (2) does not work while the ON/OFF switch is depressed, switch the power supply off and try to find the cause for the defect.
6 Make sure the lubrication oil is clean and the oil level remains in the centre of the red circle on the oil sight glass (16).
7 Be careful when you vent the tank (from the safety valve, the drain plug, or the air escape). Compressed air can be extremely dangerous. Make sure the air current does not whirl up any dust, stones or other foreign bodies. Be also sure that the air does escape in a safe way.
- In order to reduce the risk of fire or explosions, never spray inflammable fluids in an enclosed room. It is normal that sparks escape from the motor during operation. When these sparks get in touch with gasoline vapours or inflammable liquids, they can ignite and cause fire or explosions.
- Always operate the compressor in a well vented room. Do not smoke during spraying. Do not spray in the presence of sparks or flames. Keep the compressor as far as possible away from the spraying place. The liquids trichlorethane and methylenchloride can cause a chemical reaction with aluminium that is used in some paint spray cartridges and can cause an explosion. If these liquids are used, make sure the spraying is only done with spraying bins made of stainless steel. The compressor is not impaired by these liquids.
- Never inhale directly the compressed air produced by the compressor. Do not use the compressed air for filling breathing tanks.
- Do not use any welding equipment near the compressor. Do not weld anything to the air tank of the compressor: This could dangerously weaken the tank and would render the warranty invalid.
- Do not work with the compressor in the open air while it is raining, or on a wet base. Any of these situations could cause an electric shock.
- Always switch off the compressor after use and before doing any maintenance work. Press the ON/OFF button and wait until the compressed air has escaped from the tank via the drain valve. Then pull the power supply plug.
- Check the maximum admissible pressure of all devices used with the compressor. The output pressure on the compressor must be set in such a way that it never exceeds the prescribed pressure of devices or accessories.
- In order to reduce the risk of injury from moving parts, never operate the compressor without the guard fitted. Let hot components cool down before touching them.
- Read all labels and notes on the paint tank or on other spray materials. Carefully

observe all safety instructions. Wear a breathing mask when there is a risk of inhaling spray materials. Carefully check the function of the breathing mask before putting it on.

• Always wear goggles when handling the compressor. Never direct the nozzle of an accessory towards your body or towards another person.
- Do not try to adjust the pressure switch or the drain valve underneath the pressure switch cover.
- Remove daily the liquid from the tank in order to avoid corrosion.
- Pull the ring on the safety valve to make sure it works well.
- Keep the compressor at least 300 mm away from the wall in order to ensure sufficient venting for the cooling.
- Before you transport the compressor, drain the compressed air from the tank and secure the machine safely.
- Protect the air hose and the cable set from damage. Regularly examine the components for weak and worn spots, and replace them in case of need.
- Do not use an extension cable for this pro-

duct. Use instead an additional air hose in order to avoid a drop in power and a possible motor damage. The use of an extension cable makes the warranty invalid.

• After a long period of work, the outer metal parts can get hot.
- Press the ON/OFF switch to switch off the compressor. Only then cut the mains supply or pull the power supply plug.
- Before working with the compressor, check the oil level. It must be near the red circle as shown on the display. Attention: Oil must be filled in before the initial putting into operation.
- After using the compressor, press the ON/OFF switch, cut off the mains supply, and open the drain valve in order to reduce the pressure.
- Do not try to remove a part from the machine while it is pressurized.
- Make sure the lubrication oil is clean and always available in sufficient quantity. Change the oil according to the instructions given in the chapter „Maintenance“ of this manual.
- Wear safety gears including goggles or a screen, ear protection, breathing mask

and protective clothing.

• After connection to the mains and switching on, the machine starts automatically.
• Air escaping from the compressor may not be inhaled.
- Check the pressure control valve daily before starting work.
- Drain humidity from the tank. Avoid tank corrosion.
- Cut off the mains supply, remove the power supply plug, and relieve the pressure before starting maintenance work.

Wear goggles.

Wear ear protection.

Wear a breathing mask.

Never direct the output air from the compressor towards a part of the body or a person. Never try to block the air escape with your finger or a part of your body.

⚠️ Remaining hazards

The machine has been built using modern technology in accordance with recognized safety rules. Some remaining hazards, however, may still exist.

• Noise can be a health hazard. If the permitted noise level is exceeded when working, be sure to wear ear protection.
• The use of incorrect or damaged mains cables can lead to injuries caused by electricity.
• Even when all safety measures are taken, some remaining hazards which are not yet evident may still exist.
• Remaining hazards can be minimized by following the instructions given in the chapters „Safety notes“ and „Use as authorized“ as well as in the entire operating manual.

Even when all safety measures are taken, it is not possible to exclude all remaining hazards. Due to the construction of the machine, the following risks can occur:

• Injury of the lung when no breathing mask is worn.
• Injury of the ear when no ear protection is worn.
• Injury of the eyes when no efficient goggles (or protective screen) are worn.

Warning:

If an air hose is broken off or damaged, the air input on the compressor must be switched off. A broken air hose that is not supported, is extremely dangerous and can quickly start to rotate, hitting people or blowing foreign bodies

in the air.

Do not try to catch the hose. Instead, immediately remove all spectators from the dangerous area, cut off the air input, and switch the machine off by pressing the ON/OFF switch. Then remove the hose from the compressor.

Unpacking

Due to modern series production it is improbable that your compressor has any defects or that a part is missing. Should you note a fault, however, do not switch the machine on before the parts are replaced or the fault has been remedied. Not observing this instruction can lead to serious injuries.

2 Make sure that the oil level is correct and that the air filters are installed.

3 Start the compressor as described in the chapter „Switching on and off the compressor“. At switching on for the first time, let the compressor run for ten minutes at no load with the drain valve open, so that all the parts get well lubricated.

Warning: As compressed air comes off the output, the output may not be directed towards the operator or people in the vicinity. The air coming off the exit may not be inhaled. Daily check the pressure control valve.

Switching on and off the compressor

Fig.9-10

1 Check the model plate on the compressor: 230 - 240 V (or 110 - 120 V).

2 Plug the compressor cable into a standard socket (240 V or 120 V) and switch the compressor on.

3 For switching the compressor on, lift the ON/OFF switch (3) on the pressure switch cover (2).

4 For switching the compressor off, depress the ON/OFF switch.

Operation

Fig. 11

1. The pressure in the tank is regulated with the pressure switch under the pressure switch cover (2). The pressure switch is activated and the motor is switched off when the set maximum pressure is reached. The pressure comes down as the air is consumed by the connected tool, until the set minimum pressure is reached. The pressure switch then activates the motor again. The operator at the compressor must pay attention that the motor is switched on and off under the influence of the increasing and decreasing pressure in the tank. The motor starts without any pre-warning.

2 The maximum and minimum pressures are set in the factory. These settings are not to be altered.

3 All the accessory parts are connected to an adjustable discharge valve (6).

4 The pressure of the adjustable outlet can, as is evident from the work pressure mano meter (4), be changed by turning the pressure reducer (5).

Note: To be able to read the correct output at the output measuring unit, the air must flow through the outlet.

The adjustable valve must be set and the measuring unit must be read from the open valve while the air flows from the adjustable outlet through the accessories.

To increase the air pressure, turn the valve in the clockwise direction. To decrease the air pressure, turn the valve in the counter-clockwise direction.

Note: If you do not allow any air to flow during the settings, you will get a wrong display. Air must flow for a correct display.

After completing your work, or if you leave the compressor without any supervision, please switch the machine off as follows

• Hold the ON/OFF switch (3) down.
• Wait till the compressed air is released via the discharge valve under the switch cover (2).

Note: On holding the button down, you should hear a short air discharge (approx. for half-a-second).

Fig. 12

• Switch the machine off and disconnect the power plug.
• Pull the ring on the over-pressure valve (8), to ensure that the compressed air has been released from the tank, or open the discharge cock of the tank to release the pressure.

Maintenance

Warning: For any and all maintenance and cleaning, please shut the engine off and unplug the device.

Fig. 13

1. After the first ten hours of operation, drain the oil in the crank casing and refill with clean oil. To do this, remove the oil plug on the crank casing (at the bottom left of the crank casing). Note: SAE 30 or L-DAB 100 above 10 °C SAE 10 or L-DAB 68 below 10 °C

2. Always discharge the oil after 500 hours of operation and refill oil in the crank casing with clean oil.

3 After every day of machine operation, loosen the discharge screw (9) at the bottom of the tank to release the condensate.

4 Check the air filter cartridge in the air filter unit (12) regularly and replace the cartridge if necessary.

5 Check the function of the safety valve every day. During the check, the pressure in the tank should approximate the maximum pressure.

To check the valve, put the tank under pressure and pull the ring on the safety valve in the outward direction.

Air should be discharged by the valve.

Release the ring on the safety valve and the air discharge should stop.

Warnings

A pair of protective glasses must be worn while performing this test.

Do not hold your face near the safety valve during this test, because air is released there at high pressure.

If the safety valve is not working properly, as described above, switch the compressor off immediately and ask your dealer to check the valve.

Do not work with the compressor if the safety valve is not working properly, as described above.

Cleaning

1. Always keep the air inlets and outlets clear and clean.

2. Remove dust and dirt regularly with a soft brush or a soft cloth.

3 Lubricate all moveable parts at regular intervals.

4 If the compressor body must be cleaned, wipe it with a soft wet cloth. A mild washing agent may be used, but no alcohol, petrol or other cleaners.

1. Never use corrosive substances to clean the plastic parts.

Caution: The machine should never come in contact with water..
