Hi @Marsbar54,
A warm welcome to the Bunnings Workshop community and thank you for your question.
Looking at the Ozito TBS-2000 Instruction Manual and Ozito 2000W Table Saw Assembly, there doesn't appear to be an adjustment screw for the blade, which assuming the blade was installed correctly, makes me think the issue lies elsewhere.
Unfortunately, I don't have a definitive answer, but I'll try to help troubleshoot by asking you some questions. If you can answer them, I think we can narrow things down and come up with a plan.
For safety, please remember to unplug the table saw when troubleshooting and follow the instruction manual closely when removing and reinstalling parts.
If you measure from the front and back of the blade to the rip fence, is there a consistent measurement, implying they are parallel to each other? If not, can you adjust the rip fence, so they align better?
Is the blade new?
Is the riving knife in place?
If you take the blade off and place it on a flat surface, is it perfectly flat? If you remove the blade and reinstall it, ensuring all the washers are in place, does the issue continue?
How quickly are you pushing material through the saw? Does the cut start out fine and then bog down further into the timber?
If you can answer these questions, I will happily assist further and make recommendations.
Also, allow me to tag @Nailbag who has a wealth of experience in the power tools industry. He may be able to assist with possible reasons for your issues that I may have missed
Jacob
