Nip it up......
And if not "Nipped up correctly then take it back to us and we will fix it"..... And charge!!!!!
As kempy said torque it up to the correct tension.
Don't take the risk do it right, pay a professional or get a manual and do it as per manufacturers specs.

yep
just found it in manual
tighten with hand till no play in prop then nip up to next notch so you can get pin through
"tightening torque 1 Nm - upper limit 44.1 Nm"
seems quite open between upper and lower limits though i don't have torque wrench to check feel
