How Do I Adjust My Miter Saw Fence?
I have a new Hitachi C10FSH Sliding Compound Miter Saw that needs its fence aligned properly to give me a square cut. The owners manual does not address fence alignment at all (something I find strange). The left and right fences appear to be mounted with two bolts each that offer no adjustment. The fence mounting bolts look like they screw into a hole rather than a slot to allow for some adjustment. I could be wrong on that, but until I get some feedback from the forum here, I don't want to mess around with the bolts. Do have some suggestions for making the necessary adjustments?
The Answers To The Alignment And Ongoing
VERIFICATION & fine tuning apparently are in the user's manual in the vicinity of pp. 15 - 17. Due to the laser setup on this model they are fairly precise and would warrant a little trained direction before proceeding.
If you still have questions after reading these, it would be more beneficial to contact Hitachi Customer Service at:

The user manual, C10FSH_OM.pdf: can be found there also. I tried to upload it here but it is too large a file. :rolleyes: You can view it on line or download it yourself.

It is my understanding/observation that miter saw fences are
not intended to be adjusted - the fence that is - but rather, look to the stop that halts the vertical tilt to/from 90 degrees and the stop or detent that halts it at 90 degrees on rotating. See possibly #8, page 22 that speaks to accuracy of angle.
The stop is adjusted if either is off 90 degrees. Typically it is a lock nut on a threaded vernier scale (a bolt), by adjusting the bolt the stop is aligned and then locked in place.
As you pointed out in one of your own replies, drilling etc. is not appropriate, and would void a warranty.
If the adjustments described here are not found (I'm looking at them on my saw, even though not an Hitachi) Hit. technical support would be able to point them out to you in a flash.
The Correct Way To Adjust The Fence Is
First, I need to correct my own answer below saying to adjust the limits of travel on the arm instead of the fence. (Some other saws - Bosch/Skil for example, adjust the travel, not the fence). :cool:
The correct way to adjust this, per Hitachi Tech Support, 1-800-706-7337 (see posting of full access info in this thread) is to adjust the left side first, 90 deg to blade using a machinist's square or similar, loosening the fence bolts to move it - there is built-in leeway to allow movement. :)
Then adjust the right fence in parallel with the left using an accurate long straight edge.
From time to time with rough treatment etc., the fence might need re adjustment and this is the way to do it. ;)
I have also reviewed this with Jeff via PM.
