As long as your model number was good..... You don't need the entire assembly right? Just the guard. $14+ +shipping.

There is an 8mm bolt on the front of the guard. Loosen/remove this and the central guard mount will drop slightly. Behind the metal guard is a slide lock for the blade spindle. Push the lock bar and turn the blade untill it catches and is held solid. Then remove the blade fixing bolt and bobs your uncle. Alternativly, with all mitre saws, you can just pop an old bit of wood on the work base and then use the spannrer/allen key supplied to turn the blade so it bites into the wood as if you are trying to cut it. This will hold the blade steady and you will also be turning the bolt in the right direction.

The spring wraps near the shaft to pull the guard close.

Push the saw down and manually hold the guard while it is the retracted position and let up on saw while holding guard,you should
be able to put in wrench and loosen bolt.

OK first raise the cutting head. Loosen the screw that holds the guard in place and move out of the way. Find the spindle lock on the right hand side of the gearcase and turn blade by hand (UNPLUG SAW FIRST) until it locks. With the wrench supplied with saw put it on the blade bolt and turn it clockwise to loosen, it has left hand threads, remove outer flange and blade. Let me know it you need any more help

Lift the guard up and you will see a nut holding the blade. You should not have to remove guard to change blade. Make sure unit is unplugged before working on it.

Either the blade or the guard is out of alignment. You will have to check and find out which one is the culprit.
