Operation - Airpress H Manuel D'instructions

5.0 OPERATION

Compressor with direct drive:
1. The automatically operating compressor will stop at a pressure of 8 - 10 bar.
When air is used again and the pressure in the tank falls to 6 - 8 bar, the
compressor will start again.
2. Most pneumatic machines are suitable for an operating pressure of about 7 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 (b). 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:
a. Pull up the button (b) of the pressure switch.
b. Switch the button to set the right pressure (to the left to lower the pressure, to
the right to increase it).
c. Press button down again after setting to lock the button.
4. Two extra plugs (j) are fitted to the tank, which can be used to get an extra
pressure connection.
The points mentioned above are not valid for the H 85. The compressor H 85 is
executed with an adjustable safety valve and runs continuously.
Compressor with V-belt drive:
1. Check if the pressure switch (a) 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.
Checking the oil level and refreshing the oil does not apply to the oil free
models HLO 110/6, HLO 200/25, HLO 215/25, HLO 300/50 and HLO 300/100.
