I can't find this saw at Makita; so, generally. Follow all safety precautions. :-)
If the saw is running rough, the first thing I'd check is the brushes for the motor, especially if it has any age. These are fairly inexpensive and will solve a lot of woes. The next thing would be to check the thumb switch, if it has one. This is the switch that allows you to pull the trigger to run the saw, if it's just a button, then check the actual trigger switch to make sure it's working properly as it probably, not always, also engages the brushes to reverse the motor for a second, to slow it down so it stops faster.

So, check the brushes on the motor, if they show any signs of wear, it's probably them. 2nd, check the switch. Please let me know and if I've helped, give me a vote up. Thanks.

You can still find inline switch for cords, but make sure they can handle the amperage. A 15A rating should be fine. Don't use a lamp-cord switch, because they are usually rated for much lower current.
Some people go to the trouble of mounting an electrical junction box on their machine and routing the cord through it with a light switch. Once again, the light switch must have a higher current rating of 10 or 15 amps, depending on the current-draw of your machine.

I don't have table saw but my guess would be power shortage. Maybe try plugging it in different amp circuit and see if that makes difference.

Did you manage to get in contact with the manufacturer of your saw? They would surely help you with your problem.

You almost answered your own question.. As you've already discovered, the blade will slowly move as you're feeding stock to cut, so you can either locate the missing locking nut/screw, or buy a replacement from the nearest Toolshop.. Or dig out a 50-75mm machine bolt from your junk box & use this as a temporary replacement.. You'll have to check for the correct thread size 1st as they may differ from country, but I'm sure that'll solve the problem for now..

take the top cover off where yr blade is, make sure blade is in the highest position, take the 2 wrenches it came with and undo the nut.
