6.3 Failure to pull a good vacuum
➢ Be sure the vacuum gauge and all connections are in good
condition and leak-free. You can confirm leakage by monitoring the
vacuum with a thermistor gauge while applying vacuum pump oil at
connections or suspected leak points. The vacuum will improve
briefly while the oil is sealing the leak.
➢ Be sure the pump oil is clean. A badly contaminated pump may
require several oil flushes.
➢ Be sure the oil is at the proper level. For maximum pump operation,
the oil must be even with the OIL LEVEL line on the sight glass
when the pump is running. Do not overfill-operating temperatures
will cause the oil to expand so it will appear at a higher level than
when the pump is not running. To check the oil level, start the pump
with the inlet capped. Check the oil level in the sight glass. Add oil if
necessary.
