be able to use this compressor installation properly, a number of mea- surements 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 designed 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.18

ver 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.

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 (11) and the oil plug (13) 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. Before first use first read chapters 3.2 and 4.0.19

st use for connection of the compressor to an air circuit a flexible hose, to isolate vibrations from the machine. The coupling No 6 is an Orion/Airpress quick coupling.

Check if the instructions mentioned above have been executed.

2. On delivery the compressor is filled with oil. If not, fill about 0,5 litres com-

pressor oil (ref. 36398) until the red circle on the oil inspection glass (12).

3. Install the oil filler cap (13) on the crank case lid (first remove the synthetic plug).

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

use cables of sufficient capacity. Table for extension cable:

Check tension on the V-belt (14). At the right tension the V-belt can easily be turned by hand approximately 45 degrees. If necessary, improve tension. See

chapter 6.0 point 5. For daily operation of the compressor, see chapter 5.0.

6. Install the supplied wheels - with vibration damper- to the tank.

Switch on the compressor by means of pulling the pressure switch (4). The compressor will now operate, unless the air receiver is still under pressure (pressure gauge 8). Switch the machine, during operation, exclusively off by means of pushing the button on the automatic pressure switch (4); the pressure circuit will be vented and the compressor can start again uncharged.

1. Check if the pressure switch is turned off. Connect electricity. Turn on the

pressure switch. If the air pressure in the air tank is lower than the 'switch on pressure', the compressor will turn itself on, until maximum pressure has been reached. Is the pressure in the tank higher than the 'switch on pressure' the machine will not start, but will be stand by to start when the pressure drops to low.

2. When switching of the compressor, first switch the pressure switch to "0" before

turning off the electricity. The pressure switch takes the pressure off the air circuit, so that the compressor can run freely when it starts again. This prevents damage to the motor.

3. The electric motor of your compressor is protected against burning by a thermal

overload device. This device turns off the motor automatically, if the motor should get overloaded, or if one phase should fall out. By pressing the reset button on the thermal overload device after a short time, the compressor will function again.

4. After use shut down the compressor by pushing the button on the automatic

pressure switch and then pull the plug from the power supply.20

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 (11) and also remove the filler cap (13). 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 (12, middle of the glass). 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 36398 (1/2 l) or order No 36380 (2 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 (1) 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.

5. The V-belt should be checked after every 1000 hours. At the right tension, the V-

belt can easily be turned 45 degrees by hand. If tension is too high, strong corrosion will occur or eventually the spindle of motor or pump may break. At too little tension, the efficiency of the compressor decreases considerably. Tightening the V-belt goes as follows: Dismount the belt protector. Unscrew the fastening bolts on the motor sledge. Remove the V-belt. Place the motor at the right distance from the pump. Make sure that the pulley of the motor runs in the same line parallel with the flywheel on the pump (see drawing). Tighten the21

stening bolts and replace the V-belt. Worn V-belts should be replaced by new ones with the same size. Note: Regular maintenance of your compressor will increase durability and reliability. MAI NTENANCE TABLE works daily weekly every every
