The compressor does not generate sufficient pressure. The ”working pressure” and ”tank
pressure” gauges display the same pressure.
Cause

Wait until the tank pressure has increased again.
The ”tank pressure” gauge displays a higher pressure than the
”working pressure” gauge.
Resume operation.
Stop operation.
Reduce the working pressure.
Resume operation.
Air consumption is excessive.
Maximum output is insufficient.
Use a more powerful compressor.
