During operation
The doors must be closed during operation
and may be opened for short periods for
inspection and adjustments only.
Be aware not to touch hot or moving parts
when the door is open.
When the engine is running, the air outlet
valves (ball valves) must always be put in a
fully opened or fully closed position.
Regularly carry out following checks:
1. Ensure that the regulating valve (RV) is correctly
adjusted, i.e. starts decreasing the engine speed when
reaching the preset working pressure in the receiver.
2. Check the air outlet temperature of the compressor
element.
3. Check the engine oil pressure, the coolant tempera-
ture and display of control box.
4. Avoid the engine running out of fuel. Nevertheless, if
this happens, fill the fuel tank and prime the fuel sys-
tem to speed up starting.
