Daily Operation; Stopping The Compressor - Hertz HGS 2-15 Operator's Handbook Manual

If the value of the air pressure in tank does not drop; compressor will automatically stop at idle
after a short time. After waiting a couple of minutes, by opening the tank outlet vane 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). 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.

4.5 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 5. (MAINTENANCE), 5.2 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.

4.6 STOPPING THE COMPRESSOR

To switch off the compressor press the
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.
By looking at the screw 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 fan side, it
should rotate in counter clockwise direction. (That is
indicated by an arrow)
If the rotation direction is correct, restart it after 1
minute.
By closing the valve at the outlet of the air receiver
allows the tank to fill.
See that the pressure is rising from the pressure gauge
over the control panel.
See that the pressure reaches the adjusted value and
the compressor is at idle.
stop button. Your compressor will first go into idle and stop
