Default Circular saw fix

I've had this Makita saw for probably 30+ years. The lever that locks the cut depth adjustment in place won't tighten down unless I rotate it 180 degrees clockwise from where it is sitting now. That doesn't do any good, because then the cut depth is zero.

Anyone have a clue how to fix this?

Hi John - I'm guessing that the locking mechanism has been goofed up since you've owned it?

A buddy of mine who does woodworking has the following to say:

Quote:
"It’s an older mechanism, can’t really compare to my saw… I’ve seen some things about “re-clocking” the locking mechanism, but not sure how that would become a problem after 30 years. That fix is tied to bad assembly [at the factory] in the first place.

"So the re-clocking is that you remove the e-clip, remove the handle, rotate the mechanism then re-attach the handle. Can’t tell in the picture if an e-clip is used. "

John,
Is there a grommet or bushing that may have deteriorated and fallen out that may have been what allowed tightening of the lever, without the bolt going all the way down.

Ive had to swap bases on my old skil saw when the mag base broke. The thumb lock on mine is just captive to the nut that tightens the adjustment. You should be able to pull it apart reclock the thumb lock to where you you like. I would agree that a bushing/washer that rides along the rail may have been lost as the lock should move 90 Deg before it tightens.

Lol, I ran into this same problem on my Mikita saw yesterday. It locks fine with higher angles, just not when at “0”. I’m going to put in a shimming washer (if I can get the nut off!) we’ll let you know if that works.

It looks like you are missing the guide? See my saw - 810 mm Makita

Remove the small screw that holds the tear drop shaped plate. Turn the nut 1/6 rotation tighter. Reinstall the teardrop plate and screw.

Run upstairs, fix my saw, eat some lunch, back to work. All in 15 minutes.
