Hi Katchin.
What I suggest is this.With the blade removed temporarily remove the guide assembly,this is probably held on with 2 6mm bolts or cap screws and fixed to the aluminium blade guard. If your machine is 2 speed, choose which speed you want it on (I normally leave mine on fast).Clean the drive belt pulley and position the belt.Tension the belt,once tensioned, you should be able to give it about a quarter twist between finger and thumb, this should indicate the correct tension. Replace the blade and tension it as normal and see where in relation to the bed the blade ends up. Remember that the blade should run on the crown of the wheel.
If it is still too far to the left try tweaking the position of the bed. Once you are happy drop the blade guard down and run up the machine, once the blade is running true reposition the blade guides. Fit the guard with all the bearings positioned away from the blade. Move the thrust bearing, the one behind the blade, until it is no more than 1mm away from the back of the blade. This is there to stop you stressing the blade during a cut,if you are constantly rubbing it during use your blade may need a sharpen. Next adjust the guide bearings, 1 either side of the blade. They should just be off touching the blade and should be positioned behind the tooth gullet.
I hope this helps, watch you fingers and don't sue me if it doesn't work.
