Heritage OAZ turns heavily

Goal: ->The OAZ should rotate smoothly during focusing.
Solution: ->Light oiling.
Tools: ->Fine oil (bicycle shop).
Craftsmanship challenge: 1/5 stars.

Procedure:
The OAZ on the Heritages is a plastic part and may therefore be a bit rough due to the burrs. As part of our inspection of ALL astronomical items, the OAZ receives a brief special treatment.
- Screw the OAZ in and out several times.
- Clean the threads with a cleaning rag.
- Screw the OAZ in only one thread.
- Apply a drop of fine oil.
- Screw the OAZ in completely again, spreading the oil.
- And now the OAZ is running smoothly.
