Question about Hitachi C12RSH 12" Sliding Compound Miter Saw withLaser

Open Question

I have a Hitachi C12RSH. Its new. I'm setting it up and testing blade movement. When I lower the blade, the side of the blade rubs against an insert on the turntable. I need to understand how to adjust the blade so that I can move it a small amount so I can get smooth clearance between the side of the blade and the insert on the table.

    I have the same problem: When I slide the saw from rear to front it catches the edge of the plastic insert on the table so I'm wondering how to go about adjusting the blade on horizontal axis so I don't hit the plastic insert when the slider is fully extended.

Hitachi c12rsh brake

There are a few things that can cause this:
1) Check the brushes - make sure they are not severely worn and make sure they travel freely down the brush tube & contact the armature well.
2) If the brushes are OK the problem is most likely the switch. Tools with a brake have a 2 pole switch - one set will be normally open and one set will be normally closed (Most switches have a diagram printed on them) Disconnect the leads (keeping track of where you removed them) and using a continuity tester check the switch - you should get a reading between the normally closed contacts and lose it when you pull the trigger. Most likely you will find you are not getting a reading on the normally closed side and that would be your culprit. Hitachi C12RSH 12 Sliding Dual Compound Miter Saw Parts

Brand new out of box but the blade touches the insert but also seems to touch the metal base at the dust funnel. Is there an adjustment somewhere? None obvious in manual.

Check the size of the blade as it is probably 1/2 too big for the saw
The correct size blade will have a diameter that will give sufficient clearance for that machine.

Is there a way to adjust the set pin to get a true 90 degree bevel?

set the blade at the built in 90 degree lock, now use a square and adjust the fence (usually two bolts visible on top of the fence) to the blade at 90 degrees....there are some shops which offer this service under a "tune-up" or calibration.

Staple jams by driver blade in gun and I have to dismantle nose to get it out. Empire Rainco 7-16.

The problem is wear on the sides of the driver blade. With the constant up/down movement of the driver against either side of the nose plate, it eventually narrows enough to allow part of the fine wire 71 series staple to find it's way between the driver blade and the inside wall of the nose plate. A new driver blade cures this completely. Rainco tackers have become a bit rare but the good news is, they're actually manufactured by Fasco and the Fasco driver fits into the Rainco piston by the removal of a single pin to allow the old blade out, replace with the new Fasco blade, re-insert the pin into the piston, then re-assemble the gun and you're away.

My saw was received with the saw blade not tracking parallel to bottom guide. It appears to be shipping damage. Is there an adjustment to correct this problem?

I noticed your post after I just posted the same problem (you worded it better). Did any magic answer other than returning the saw (presumably damaged in shipping) ever materialize?

How to change the saw blade

See Figures 43 - 45.
 Unplug the saw.
 Lower the saw blade, raise the blade guard, and remove the throat plate.
 Make sure the bevel locking lever is securely pushed to the left. Raise the saw blade to its full height by turning the height/bevel adjusting handwheel clockwise.
 Using the smaller hex wrench, insert the flat open end into the flats on the arbor shaft.
 Insert the closed end of the larger hex wrench over the hex nut. Holding both wrenches firmly, pull the larger wrench forward to the front of the machine. Make sure the blade nut is securely tightened. Do not overtighten.
Check all clearances for free blade rotation. See To Set the Scale to the Blade. In cutting operations, the scale will be set to the side of the blade where the cut will be measured and made.
To replace the blade with an accessory blade, follow the instructions provided with the accessory.
To install a standard blade:
 Place the new blade on the arbor shaft (the teeth must point down toward the front of the saw to work properly).
 Place the blade washer and the blade nut over the blade arbor. Be sure the dome side of the blade washer faces out from the blade and that all items are snug against the arbor housing. Tighten securely.

Fig. 4535
 Rotate the blade by hand to make sure it turns freely.
 Lower the saw blade and reinstall the throat plate.
NOTE: Securely tighten throat plate screws. Do not allow the throat plate to bow up above the table surface.

Noisey fan

In my case noise was coming from the plastic blade rubbing against the sheet metal housing. I removed the motor and added 2 washers to the mounting screws. The washers acted as spacers and lifted up the motor/blade assembly with respect to the sheet metal housing. The blade no longer rubbed against the housing and the noise stopped.
