be able to use this compressor installation properly, a number of measurements must be taken. The following points will contribute to making you a satisfied user of this installation.

ying your Airpress compressor installation, you have become the owner of a compressor installation with a high performance and reliability level. Correct use and regular maintenance will increase the life of the compressor. In this manual you will find operation and maintenance instructions. Read it carefully and keep it as a guide to your compressor. The compressor has been built to supply compressed air. In particular the appliance cannot be used to produce air to be breathed by humans or used on direct contact with foodstuffs. The appliance must be used only for the purpose for which it was specifically designed. All other uses are to be considered incorrect and therefore unreasonable. The manufacturer cannot be held responsible for any damage resulting from improper, incorrect or unreasonable use. This machine is not suitable for external installation.

portant: please read and observe the following safety instructions before

ing the machine. Nobody must be allowed to use the compressor unless they have read the instruction manual and have been instructed in the regulations to follow for correct and safe use. The machine must be used by adults only. Use of the compressor by apprentices of not less than 16 years of age must be supervised by an adult authorised to use the machine. Keep children and visitors away from the working area. Be cautious when using compressed air. Never aim the air flow at people or animals. Do not use compressed air to clean clothing. Compressed air is not suitable to inhale. Do not wear loose clothing or neckties that can get caught in moving parts. Preferably wear safety goggles, nonslip footwear and Wear protective hair covering to contain long hair. Only use the machine outside in dry, well-ventilated surroundings and do not expose the machine to rain. The compressor should be placed in such way that all points, destined to carry it will really do so. Take also care of a horizontal position. This machine is not fit for continuous running, but service for 30% per 60 minutes. Keep your work area clean and well lighted. Do not use the machine in areas where fumes from paint, solvents or flammable liquids pose a potential hazard. Do not exceed the maximum operating pressure and only use the machine in an ambient temperature between +5ºC and +40ºC. Never attempt to tamper with the protections of the log splitter or to operate the machine without these. The working parts of the machine can become hot during operation. Let the machine cool down after use. After each use the tank must be vented and the moisture collected in the tank must be bled. Not bleeding the tank can lead to leakage and may cause a dangerous situation. Check that the electric circuit is adequately protected and that it corresponds with the power, voltage and frequency of the motor. Check that there is a ground connection and a regulation differential switch upstream. Use cables with an adequate section and avoid use of free and inadequately insulated connections. Never open the pushbutton box on the motor. Should this be necessary, contact a qualified electrician. Make sure that the machine and the cable never come in contact with water. Treat the power cable with care. Do not attempt to move the machine by pulling the cable. Do not yank the cable to unplug it; keep the cable away from excessive heat, oil and sharp objects.16 Never leave the machine unattended with the power supply "on". Also disconnect the power cable when: - you leave the machine, even for a short time - not in use - carrying out maintenance work - changing attachment or moving the machine.

WARNING: the warnings, cautions and instructions discussed in this

instruction manual cannot cover all possible conditions and situations that may occur. It must be understood by the operator that common sense and caution are factors which cannot be built into this product, but must be supplied by the operator. Only those persons who are aware of how to use the compressor by having read this manual, should use the machine. Injudicious use may cause danger.

nger plates (page 30) The plates fitted on the compressor unit are part of the machine; they have been applied for safety purposes and must not be removed or spoiled for any reason.

PLACING The compressor should be placed in such way that all points, destined to carry it will really do so. Take also care of a horizontal position. The engine should get sufficient cooling air; so never cover the ventilating openings. Place the compressor in a cool dustfree space. Never place the compressor in a room where will be sprayed. Paint spray will clog the air filter and will also deposit on the compressor. Mind that the draintap for condensation water (10), the oil drain plug (9) and the oil plug (6) will always remain attainable. We suggest to leave a space of aproximately 30 cm for ventilation and maintenance. Notice: Insufficient air supply, too high temperature and fouling of the air filter reduce the efficiency of the compressor considerably.

the factory the machine is already fully equipped with cables. The machine now has to be connected to your own electricity supply. Connect the machine to a separate group. Beware that voltage and amperage of your electric circuit meet the needs of the motor. Use only cables with the right diameter. The factory suggests to use cables of at least 2.5 qmm and a maximum length of 10 meter. The compressor is equipped with a thermic overload (no. 11, page 1), to protect against overload and undertension. Before first use first read chapters 3.2 and 4.0.

AIR CONNECTION17 Best use for connection of the compressor to an air circuit a flexible hose, to isolate fibrations from the machine.

Check if the instructions mentioned above have been executed.

2. On delivery the compressor mostly is filled with oil. Fill about 0,8 litres

compressor oil until the red circle on the oil leveler.

3. Install the air filter (1) in the cylinder head (first remove the synthetic plug).

4. Install the oil filler cap (6) on the crank case lid (first remove the synthetic plug).

5. Avoid the use of extension cables. If you use them, unroll them completely and

use cables of sufficient capacity. Table for extension cables:

When the compressor does not function, it is possible that it has fallen out thermically. Use the thermic overload (pos. 11) to reset.

Switch on the compressor by means of the pressure switch (7). The compressor will now operate, unless the air receiver is still under pressure (pressure gauge 2). Switch the machine, during operation, exclusively off by means of the button on the automatic pressure switch (7); the pressure circuit will be vented and the compressor can start again uncharged.

The automatically operating compressor will stop at a pressure of 8 bar. When air is used again and the pressure in the tank falls to 6 bar, the compressor will start again.

2. Most pneumatic machines are suitable for an operating pressure of about 6 bar.

For some applications this pressure is even lower. To be able to set the right pressure, the compressor is provided with a reducing valve (3). This valve can set the pressure of the air receiver (of course never higher than the pressure in the air receiver).

3. The setting of the reducing valve is done as follows: switch the button to set the

right pressure (to the left to lower the pressure, to the right to increase it). The set pressure can be read on the pressure gauge (4).18

MAINTENANCE Before carrying out any maintenance jobs it is obligatory to stop the machine, disconnect it from the power mains and make sure that the tank is pressure free by opening the condensation draintap (10).

1. After the first 50 operating hours and then every 250 operation hours the oil

should be refreshed. Turn off the oil drain plug (90) and also remove the filler cap (6). Collect the oil. If the oil does not come out any longer, switch on the drainplug again and refill the oil (through fillercap) until the oil has reached the correct level. The right oil level is on the red circle on the oil leveler (8). Always respect the regulations in force for disposing of old oil!

2. Regularly drain condensation water. The draintap is situated at the bottom of the

tank (10). Draining with pressure in the tank is the easiest way. Some compressors have an aftercooler with its own drainplug. Also from this device the condensationwater should be drained regularly. Condensate must be disposed of in conformity with the local regulations in force (not in the sewer!). As an alternative you can place an oil/water separator.

3. The oil level should also be checked regularly. For the right oil level see point 1. If

necessary refill with compressor oil, order No 12491 (0,6 l) or order No 12492 (1 l). Checking daily can prevent a lot of troubles! Use oil of the same type as that already in the machine; do not mix different types of oil!

4. The air filter element (3) should be cleaned or changed regularly. This change

depends on the amount of fouling and should be done more often in dusty situations and less often in a clean situation. For cleaning the filterelement, take out the filtercontainer with the filter. Then clean the filter by blowing off the dust. Note: Regular maintenance of your compressor will increase durability and reliability. MAINTENANCE TABLE works daily weekly every every

refresh oil (first time after 50 hours) ▀19
