You have to have a spanner wrench. One you have that, remove the safety ring, use your spanner wrench, and it comes right off.
I'm not sure what you are actually asking. But, spanner is simply the British term for what we call a wrench. Haynes manuals use British terms like boot/trunk, bonnet/hood, etc. Hope this helps. PreachJohn -- If you're asking what I was asking (and figured out) you're referring to that odd hooked "pin spanner". The trick for me was to figure out what I was supposed to hook the spanner onto and then twist like a normal wrench. I was trying to adjust the shocks on my motorcycle and it became much easier when I noticed the gear-like ring below the springs that worked admirably for getting a decent grip with the spanner to twist the adjustment ring.
u can use a spanner if u need to fix something like a screw on the door

Because a spanner provides extra leverage - and is much tougher than our fingers !
Usually made of steel.
