Sugino 75 BB tapers come with a light grease film already on them.
You probably want to tighten them to about 80% - 90% of your strength with your hand about 10-15cm down allen key or rachet. I found that this gave about 30nm torque*
I would not 'go for it' on a larger rachet as although it probably won't cause any problems / damage in use it will be harder to get off.
