INSPECTION DURING OPERATION
A:
Check the oil manometer before every start -up. The oil pressure must not drop
below the minimum value of 0.3 bar, (normally 1-3 bar). When outside temperature
is low it may take a few seconds before the oil pressure is visible.
B:
Check the air filter indicator.
If the red mark is visible, the air intake filter is soiled and poses a risk of overheating
and damages.
C:
The safety valve must open at maximum air pressure.
This valve must NOT be used as blow -off valve. To prevent overheating in the
enclosure the valve at the silo tank must blow off before the compressor valve
does. (blow -off pressure 2.5 bar)
D:
Pay attention to any unusual sounds or peculiarities near the installation.
E:
The fan must rotate to a sw itched-on PTO
Check the functioning of the fan.
This check may only be carried out by skilled mechanics. Observe the safety very
carefully, the enclosure must be removed and rotating parts will be accessible.
F:
If the installation is equipped w ith an external oil-cooler check if the control light is
on (image 3.1.2). You w ill find the safety fuse in the sw itch box.
