Ive been using the ts 410 on correct fuel mixture but the pistons are damaged , is there any other cause for this
Dirt coming through the carb. Stihl saws have chrome plated cylinders. Is the cylinder damaged?
Power cutters run in a very dusty enviroment, if concrete dust passes the filter and enters the cylinder it will very quicky remove the plating on the cylinder and wear the piston skirt, once into the bearings it will destroy them, if the rings are badly worn ( remove them from the piston and check the end gap by entering them into the cylinder, if the gap is excessive you have had dust entering the cylinder )
i work for the local council and we use dust supressors ( water bottle) could dust still get through??
Yes, even useing water there is still a great deal of dust about, a classic sign to look for on the cylinder wall is a shaded area just above and below the inlet port, this is where the nicasil liner has worn through to the alloy, it is very important never to blow the paper filter out with an air line this will destroy the filtering capacity

I have owned and use Stihl saws for the past 18 years and I have seen both these problems many times. as for the chain 'getting tight' -- when you go to adjust the chain, make sure you are lifting up on the tip of the bar as you set the tightness -- you should be able to only pull the chain away from the bar about 1/8th of a inch. now, while tightening the bar bolts make sure you still are pulling up on the tip of the bar,, and make sure the bar bolts are nice and tight -- not to tight though, the bolts that Stihl uses are a very weak point on their saws and I have broke more than just one. but make sure after one is tight that you tighten the other one and then give the first nut one more 'little' nudge tighter. new chains do have a break in period and they have been known to tighten up and loosen as they are running,, just keep your eye on it for awhile and thighten or loosen as needed.
now I am kinda confused on your next problem -- you say ' winter mix bar oil ' -- using this oil should not have anything to do with it stalling out, ( enless you are mixing bar oil with your gas ?? ),, make sure you are using Stihl 2-stroke oil to mix with your gas at a ratio of 50:1,, ( you can buy small bottles that mix with 1 gallon or a bottle that will mix with 5 gallons -- use 'em ). one thing that I have had troubles with when my saw wants to stall out is the fuel filter inside the fuel tank in the wrong position and is sucking air. also I have had fuel lines that crack and/or split and they **** air.
now the winter bar oil -- please,, I have been running Stihl saws in temperatures ranging from minus -5 to 100 degrees above and I have always used the SAME bar oil year round and had NO problems. on the side of the saw there is a bar oil delivery speed screw and you can adjust it to flow more or less -- your manual should show you the exact location of this screw,, make sure you clean out any debris that might be blocking the weep hole for the oil delivery. you need to make this adjustment with the bar and chain off the saw and you will see the flow of the oil and you can adjust to a good flow.
I am a firm believer in buying and using Sthil chainsaws,, I will never buy anything else,, they are great and out last any other saw I have used or seen,, and your Farm Boss is a great saw and should give you many years of trouble free use.
one suggestion that I would make real quick is to ' change your saw mechanic ' -- find one that has been ' WORKING ' on chainsaws ( not just selling them ) for along time,, someone that has your interest at heart and is there to help you,, not just to take your money.
(((( I am still laughing at the ' Stihl Winter Mix bar oil :-) )))).
good luck with your saw,, and if you have anymore questions about this please feel free to write me back here and I will do my best to walk you through what it is that you need to know and do. again - I have been using and working on chainsaws for most of my life.
have a great night,

SOURCE: keep burning up piston on
It sounds like you are running lean. Not a lean oil/gas mix but a lean Air/fuel ratio. This engine runs hot as a high performance engine. any air leaks such as crank seals, manifold gaskets or muffler gaskets can give you too much air for the fuel coming in.
Secondly from the fuel side:
Ethanol (curse it) combines with oils that have no nondispersants making a white chalky poweder in the fuel system causing less fuel to mix with air. any blockage or pin hole leak can cause less fuel to be brought into the engine thus less cooling and lubricating.
Your carburetor and fuel filter need to be serviced and adjusted correctly or they will affect the mix.
When done the engine should run no faster than 13,000 rpm top no load speed.
This engine should idle smoothly at 2,500 with no more than 150 rpm change
if the speed is not as listed above when the rebuild is done you need to go back into the machine.
Call up a shop like www.arcolawn.comto get a EDT8 tach. it is well worth the money.
good luck

They will score one side of the piston because of the heat.Its always on the exuast side.It could be the carb is adjusted to lean that makes it run hot.The muffler might need a good cleaning too?If it gets plugged up it will run hot too?It sounds like you gas and oil are mixed right.Thats about the only thing that will do it besides straight gas run in it.Could be the shop tec doesen't know how to adjust the carb?I would ask the to make sure its adjusted right.And not to lean.If its any kind of shop someone there should know how to do it right.When you get it back try running it wide open it should do whats called 4 stroke when not cutting wood then smoothe out while cutting.If you hold it about wide open and it runs fine.Its not right.If it does you need to open the high side of the carb a little.Maby a 1/4 turn at most.Just untill its getting to much gas to run smoothe.I hope they fix it right this time.Thats a very nice saw!
