start by cleaning the air filter, blow it out realy good, alot of times the carb gets dirty spray some carb cleaner in it just a little at a time, if you haven't changed the plug i would do that too.

There is no one gauge that is common to all new Stihl saws. Gauge is completely dependent on the bar chosen.

The standards are 0.043, 0.050, 0.053. 0.058, 0.063, 0.080.

You should be able to find your chain gauge on the bar. Even if the paint is worn away, you should see the impression from the stamping. If all else fails, take the chain into a Stihl shop and they will have no problem finding what you need.

The centrifical clutch is probably rusted (or has a broken spring). You can try a small amount of WD-40 inside the clutch to see it that will break it loose.
Also, be sure that the chain tension adjustment is not too tight!!

28866.png This is the only diagram that is offered for this model but on the multifuntion switch (#33) The wire is layed through the upper part of it with the metal connector sticking out of the left side and once there you will pull the wire to the right until the metal connector is seated in the switch. After this reinstall the switch into the handle houseing and make sure that the contact spring (#24) is sitting on top of the switch and when in the off possition making contact with the metal conector of the wire on the switch.

This isn't a 100% solution, but a saw only runs as clean as the air filter, and they get dirty quick. I give my air filters a quick wash about 5-7 times with just soap / water.

If that doesn't do the trick, your probably looking at some kind of carburetor issue.

Use a volt meter to see if the battery is depleted or not. If you replace the battery and the alarm stops then it was a weak battery, If it keeps on then there something setting it off. You can use the information in the owners manual Oregon Scientific BAR629HGU Manuals to troubleshoot it.
