The handbook of my Makita circular saw goes into detail about changing the blade, with diagrams too. I can't see any mention of whether it it's clockwise or anticlockwise to release the blade. I've tried both and am getting big resistance. I would try much harder but there's a warning about doing such things forcibly. Maybe a bit of a silly question but I don't want to break anything at this stage, or any other come to that.
Simple/silly? Question about my Makita circular saw

Generally the securing thread is chosen such that it tightens in work. I don't know if this applies to your Makita.
Thanks. I vaguely remember this as a general principle. I just wanted to be sure,
Yup - the fixing should tighten in use (a blade spinning off the arbour in use might not be good!)
Most cordless saws have the blade to the left[1], so the blade will exert an anticlockwise torque on the arbour - hence the thread needs to tighten in that directly.
[1] not sure why they switch from the normal right hand sided mains configuration. (some of the twin 18V models are the same way around as the mains ones)
Tightening should be the opposite of the the blade spinning direction, hence to undo you turn in the same direction the blade revolves. Most circular saws rotate anti-clockwise when viewed from the blade side and as far as I can tell so do all Makita saws.

If you clamp the blade, soft jaw vice, I can't see excess spanner torque impacting on the driven side.
Yup.
True for mains, but not usually the cordless.

Probably true for mains ones.
