Tuscan timing chain
Discussion
It is described in Graham V's Sagaris guide
Top one is basically slacken lock nut, rotate til "tight" (anit clock) with engine running, then allow to just slacken off naturally (just under tension from shaft), then lock with nut. Lower one is similar but remove M6 lock screw, then loosen large lock nut, tighten shaft until tight (anit clock iirc) (you can hear chain hum when tight) then loosen by one whole hole on the round locking plate (flip plate to get 1/2 hole). Use big lock nut to hold in place and refit M6 with threadlock.

Important:
But do it only when engine is in fully warmed up situation, otherwise when you do it when engine is cold the chain will be too tight when engine has expanded!
