I was looking at that but when holding it up to the saw, the guard opening is centered when it's on the outside, plus there's less places to deflect sparks and collect dust so I assumed it might go on the outside.
Was wondering how long it would take the factory correct police to catch me! Not long, I'm a horrible criminal
Amazingly the extra guard piece is not shown in either the parts list or brochure leaflet, I only have pictures of three other Orline Circular Saws, it's only visible in this one (where it's fitted to the outside of the guard) link below;
It's hidden by the blade in the pictures of the other two saws I have.
Also the brochure confirms the blade size as 8" (same size as used on the Comet C/Saw), both an abrasive wheel and saw blade were available for the Orline Saw.
