Compressor
Oil level (Only on older units)
The oil level must always be visible in the oil level glass.
Max. level is at the middle of the glass. An oil level that exceeds maximum results in higher oil consumption.
The safety valve is set and sealed at the factory at the highest permissible pressure. The pre-set pressure must not be changed.
If the safety valve has been opened, either through manual testing or in the event of excess pressure, the compressor must be stopped in order to close the safety valve again.
The pump head and valve must be removed and cleaned from internal carbon deposits every 1000 hours (at least once a year). New valves and head gaskets must be installed.
Service intervals
| Check oil level | Weekly |
| Oil change* | 300 hours |
| Replace valve | 1000 hours |
| Suction filter** | 1000 hours |
| Complete overhaul | 4000 hours |
| * During the commissioning phase, the oil must be changed after the first 30 hours. ** Foam rubber filters can be cleaned in detergent water - rinse afterwards with clean water. |

| Total quantity of oil 0.12 l. Quantity of oil in l. between min./max.: 0.025 l. The reciprocating piston compressor's max. oil consumption must be 0.02-0.1 g/m3 emitted air. The oil consumption can vary, however, depending on the operating conditions (the specific gravity of the compressor oil is approx. 880 g/l.). |
