How do I square the blade? My blade runs out by 2mm .

There are three different "squares" you can check. The vertical square -
i.e. is the tilt 90 degrees to the table surface in the full upright
position. Most saws have adjustment screws on the limits of the tilt
mechanism to set this.

Next thing is to get it parallel to the slots on the table surface. Many
saws will allow the bolts retaining the table to be slackened and the
angle of the table shifted slightly. To check this place a bit of wood
in the slot and slide something about the right width up to it, and
align the blade so it looks parallel to the wood. Then use a dial test
indicator so that you can run it along the blade against something in
the slot. Again tapping the table gently until they are properly parallel.

Last thing it to align the fence. There are usually adjustment screws
for this - you can line that up with a table slot to start with, and do
a final check against the blade. (if you did the previous step right,
then the blade and the slot should be parallel anyway).



I guess the other possible fault that could need "squaring" is swash in
the blade, caused by poor seating in the washers or distortion of the
blade itself.
