Daily Operation; Stopping - Hertz HSC serie Bedienungshandbuch

When the energy and air lines of your compressor are completed, inform your service for
commissioning. Our service will perform the general inspections, start up the compressor and supply
you beneficial information related to your compressor and its maintenance. If you want to start up the
compressor by yourself read this handbook very carefully. Performing an erroneous process may be
hazardous for your compressor facility or the personnel working in this region.
Check the oil level. On the separator tank body there is a transparent hose for easily seeing the oil
level. Check the oil level when compressor is stop position. During operation the oil level may vary.
If the oil level is missing, complete it. Information related to oil is described in chapter 6.
(MAINTENANCE), item "COMPRESSOR OIL".
Check the internal components and connections of the compressor. Make sure that during
transportation it has not been damaged.
Apply energy to the compressor and check whether the compressor motor is running in correct
direction. The running direction control of compressor: should be made during commissioning.
For this, remove necessary covers.
By looking at the airend pulley of the compressor; press the "Start "button and run the compressor for a
short while (1-2 seconds) and stop it by pressing emergency stop button. When looked from airend
pulley side, it should rotate to air end shaft direction. (That is indicated by an arrow on top of the pulley
and embossed at the airend body).
If the rotation direction is correct wait for one minute and restart the compressor. Be sure to outlet valve
of compressor is fully open.
By closing the valve at the outlet of the air receiver allows the tank to fill.
See that the pressure is rising from the compressor control unit screen or from the pressure gauge over
the control panel.
See that the pressure reaches the adjusted value and the compressor is getting idle.
If the value of the air pressure in tank does not decrease to load level; compressor will automatically
stop at idle after a short time. After waiting a couple of minutes, by opening the tank outlet valve
observe that the compressor is loading at demanded pressure level.
After 10-15 minutes, check the operating temperature of your compressor and see that it is normal 80-
90 °C (depends on the ambient temperature). Switch off the energy of compressor by stopping and
check internal accessory of compressor by eye. This is very important against the probability of oil leak
or loosening
All the functions and reliability of your compressor has been tested after manufacture. The above
mentioned information of commissioning is against the probability of your compressor being damaged
during transportation. If you can not see a failure status after all controls you can start up the
compressor.

5.4 DAILY OPERATION

At normal days before running your compressor you may perform some simple checks and afterwards run it.
The maintenance activities are explained in the section 6. (Maintenance) "Daily Maintenance" part.
Observe that there is no failure warning signal on compressor panel.
Observe that there is no oil leak or damage by looking at the internal accessory.
Run the compressor and observe how it works for short time.
Look at the front panel and observe that operating pressure and temperature values are normal.
While the compressor running on load, observe the oil flow at oil return line.
These simple checks may cause you to early detection of failures and save you from loss of time from
unnecessary stopping.
5.5 STOPPING THE COMPRESSOR
To switch off the compressor press the stop button. Your compressor will first go into idle and stop within 20-30
seconds. After the compressor stops observe that whether or not there is any damage, oil leakage etc in the
inside by opening the covers.
