seconds from the nozzle tip side, and about
5 seconds from the nozzle mounting side.

Use a commercial oil-blotting paper to check
the residual oil inside nozzle if necessary.

Performing step 5 is usually sufficient to remove oil
remaining in the nozzle. However, if oil still remains, blow
air through the nozzle once again.
