Topic tags/keywords: hitachi c12rsh miter saw adjustment

Greetings!

Based partly on the outstanding reviews of this miter saw, I recently took delivery of a reconditioned one from Big Sky Tools. I finished making a stand for it last evening, got it mounted securely and, began working with it today.

I am a bit disappointed in its accuracy. When I cross cut a board, it is out of square by about 1/16 inch over 4 inches. By following the directions on p. 31 of the User’s Guide, “Miter angle fine adjustment”, I was able to get it to cut much more accurately. However it is out of its 0-degree detent. When I put it back in the detent, the error returns.

Is there any way, once the correct angle is found, to permanently adjust the 0-degree detent to match?

Many thanks,

George

I bought a router from BST 4 years ago. The first one had a problem with too much runout. I returned it for exchange and the 2nd one was fine.

I’d hate to have to do that for something as large as a miter saw, but it was a relatively painless exchange for me.

I rarely remember model numbers, but I might have the same saw – but got it news at Lowes on a screaming deal.

[EDITED to say] No. Yours is a slider while mine in the non-slider. I just looked it up

Sad to say I’ve never used it – just bought it on impulse when I walked through the store one night. I’m still using my Dad’s old Craftsman RAS. Mine is a 12” double bevel non-sliding saw.

I have the same saw.

There are no instructions in the manual on how to square the saw to the table and to the fence.
The adjustment you are talking about is how to fine tune an angle cut.

To adjust the blade square to the fence, you have to adjust the fence. See this video.

If the blade is not perpendicular to the table then you have to adjust the stop or the rails.

Here is another video on making 0 clearance slots.
