Rear shock adjustment

[Hawkeye]

Hi guys, my mean green machines back shock adjustment does not want to turn. I don't want to force it.
I can take it off and work on it but it means undoing the oil line which means having to put more oil in the shock some how. Can I just hold the pipe higher than the shock maybe. Any ideas anyone.

All sorted, Took the knob off then put a 14mm ring spanner on the shaft and slowly worked it R/L until it moved.
Then just smeared the threed with antiseize. Job done.
I recommend everyone to do the same. It would only take 5 mins.
