(Using the block of wood) That is probably safer than how it's own manual describes how to do it. It describes trying to hold the blade with your fingers of the opposite hand! Axminster TS-200 User Manual (Page 26 of 32)
Not a good design safety wise. You would think that there might be a cutout for a spanner on the arbor shaft, but there isn't.
By design, if you don't use anything for a spanner to lock the arbor shaft, then other designs do that by drilling a hole through somewhere... into the arbor shaft, so you can lock it with an arbor locking pin.
That type of design on your saw (even if it is a lack of) goes back to the old sidewinder hand-held circular saws, where you used the same technique. But that design evolved with progress and insight on safety right? Just IMHO.
One thing your manual notes, is to not tighten the arbor nut too much. It's arbor washer uses pins to lock it in place, so the arbor nut is not going to spin off... But if you tighten it too much, since the arbor does not lock, it's going to be difficult to get off. The drawback to that design, was that if it was tight and you keep using blocks of wood to stop the blade, that it tweaks the blade so it is no longer true. Then you get blade wobble. Just take care with it and keep things in mind... understanding how it works and what to look out for.
