I recently purchased a factory refurb Hitachi C12RSH due to the fact i couldnt find one bad thing said about it. Well after entirely having to reconfigure my miter stand due to the size of it i went to work getting it perfectly square/accurate and no surprises there amazingly.

Though theres one thing i cant get accurate, and thats the laser. Those of you who are familiar with this saw know the laser is adjustable to the left or right of the blade which is awesome IMO. But the laser is off kilter in regards to squareness with the fence and im not seeing any blatantly obvious ways to adjust the angle. Before i start tearing into or breaking it any suggestions from people that have used this saw?

Rammstein1224,
I have the same saw and I am moving my shop. I expect to have to deal with the same issue when I set it back up. I realize you posted this back in 2018. Did you ever figure out the problem? BTW I have actually been fairly unimpressed with this saw. After using an old Makita with a cast iron base, it feels kind of light to me. I am not confident with the accuracy of the angles and it just feels under weight for the big cuts. I’m thinking of just keeping it and putting a slider next to it. Probably a Makita again.

I toured you shop on your home page and it is pretty awesome. I guess you have spent some serious time setting it up. My new space is a basement with water problems so I will be fixing that before I can get it set up again.

Thanks for any input.
Best regards,
Tim

I never did find a solution, the idea of a laser that is adjustable to both sides of the blade sounds great but isn’t when there isn’t any adjustablilty angularly. I ended up buying a Laserkerf and while i don’t quite 100% trust it yet it hasn’t given me any reason not to.

The knob on the right adjusts the beam left and right. To adjust square to the fence there is a little rubber plug that covers hole to set screw. Stick 4.5mm Allen key in there and you can adjust the square of the laser. The picture shows the little rubber plug I pulled and where the Allen key goes.

I have a Hitachi miter saw with a laser. I never was able to get it to show on the left or right side of the cut. It was like the adjustment screw ran out before I could get it over the cut so I just gave up. In the end it and the stand took up too much space in my shop so I put it in storage but not because the laser was wonky.

Yes, I’m having the same problem. I have plenty room to put the laser on the right side of the blade, but it runs out of thread or something just short of putting it to the left side. Is there a way to adjust this so that the knob has some leeway on each side? I tried a longer screw, but that didn’t seem to help any. It’s as though the laser is just mounted too far to the right, or the blade is too far to the left – but not much – maybe 1/32 of an inch.
