Frequently Asked Questions - HL 36050 Airpress

How to put the Airpress HL 36050 compressor into service?

First ensure that all installation recommendations have been followed. Check the oil level (must reach the red circle) and top up if necessary with about 0.8 L of compressor oil. Mount the air filter and oil filler cap. Plug the unit into a 230 V socket. Use the pressure switch (7) to start. If the compressor does not start, the thermal protection may have tripped: press the red button (11).

What type of oil to use and how to drain?

Use specific compressor oil (ref. Airpress 12491 or 12492). To drain, unscrew the drain plug (9) and remove the filler cap (6). Let the used oil flow into a container. Screw the drain plug back on and add clean oil up to the red circle level on the indicator (8). Change the oil every 250 hours (first change after 50 hours).

How to adjust the output pressure?

The compressor is equipped with a pressure reducer (3). Turn the knob: to the left to decrease pressure, to the right to increase it. Read the resulting pressure on the pressure gauge (4). The maximum tank pressure is 8 bar; most tools operate at about 6 bar.

How to drain condensation water?

Condensation accumulates in the tank. To drain it, open the drain valve (10) located under the tank. Perform this operation preferably under pressure. Condensation water must be disposed of according to local regulations (do not pour into the drain). It is recommended to drain daily.

What to do if the compressor does not start?

First check the mains fuse. If the tank is under pressure, release it. If the motor does not run, the thermal protection (11) may have tripped: press the red reset button. If the problem persists, the pressure switch or motor may be defective; contact an authorized repairer.

How to clean the air filter?

Remove the plastic housing of the filter (1) and take out the element. Clean it by blowing with a compressed air gun. In case of persistent soiling (paint, etc.), replace the filter. The cleaning frequency depends on ambient pollution; clean air is essential for performance.

What is the recommended service pressure?

The service pressure is 6 bar. The compressor automatically stops at 8 bar and restarts at 6 bar. Use the pressure reducer to adjust the pressure to your tools (usually 6 bar or less).

Can I use the compressor continuously?

No, this model has a duty cycle of 30% per 60 minutes. This means it can run for a maximum of 18 minutes per hour; the rest of the time must be used for cooling. Continuous use would damage the unit.

How to change the compressor oil?

Place a container under the drain plug (9). Unscrew the drain plug and the filler cap (6). Let the used oil drain out. Screw the drain plug back on. Pour new oil (0.8 L) up to the red circle on the level indicator (8). Recycle used oil according to local regulations.

What are the essential safety instructions?

Never direct compressed air at people or animals. Do not inhale compressed air. Use the compressor only in a well-ventilated area, away from moisture and flammable liquids. Wear safety goggles. Disconnect the unit before any maintenance. Do not exceed the maximum pressure of 8 bar. Children and untrained persons must not use the unit.

• 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 +5°C and +40°C.
• 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.

Danger 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.

3.0 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 approximately 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.

3.1 ELECTRIC CONNECTION

At 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.

3.2 AIR CONNECTION

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

4.0 FIRST USE

1. 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: 0 - 10 meter: 3 x 2,5 mm ^4

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

7. Switch on the compressor by means of the pressure switch (7).

8. The compressor will now operate, unless the air receiver is still under pressure (pressure gauge 2).
9. 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.

6.0 OPERATION

1. 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).

6.0 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!

1. 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.

1. 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!

1. 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.
