Ryobi 245EMS Sliding Mitre Saw slightly out of true.

[MikeCushing]

Hi, I saw this saw on offer at B&Q and it looked a decent product so it came home with me. It's my first Ryobi tool, but my son has a good stock of them and swears by them,

 

Out of the box, when et to 0 degrees, a practice cut tested by a T square shows the cut to be around 1 degree short of the expected 90. That's enough to throw a lot of stuff out of sync. 

 

I'm sure there must be a way of adjusting the thing, but I'm blowed if i can make sense of the poor instructions.

 

Just wondered if anyone else might be able to help?

 

Thank you

 

Mike
