E07 [Insufficient flow rate for oil removal]
<When this error is supposed to occur>
Circulation mode
Same amount of oil replacement check
<Error detecting condition>
The flow rate is approximately 200 mL/minute or less.
<Why should the machine detect this error?>
When the flow rate is low, the precision of the flow meter becomes lower, and a margin of error may become substantial
after oil replacement.
<Display and sound>
Digital display:
“E07”
Error buzzer:
Sounds.
Warm the oil.
Check the connection of the coupler.
Signal light, Red:
Flashes.
START LED:
Flashes.
<Causes>
1.
Since the temperature of the wasted oil is low and its viscosity is high, the flow rate is low.
2.
Since the automatic valve filter is clogged with dust or any other thing, the oil cannot flow easily.
3.
Since the automatic valve and the connection hose for circulating oil are not set correctly, oil leaks.
<How to recover this error>
1.
Idle the engine sufficiently to raise the oil temperature.
2.
Clean the filter to remove the dust or any other thing.
3.
Set the automatic valve and the connection hose for circulating oil correctly again.
When you press the START key, the machine restarts removing the wasted oil. When the machine confirms that
the flow rate is more than the regulated value (approximately 200 mL/minute), it resumes the operation that had been
performed before the error occurred.
If the flow rate does not increase for any other reason, the machine detects the E07 error again. Contact our
Service.
