SOURCE: hi,my stihl ts 410 saw

Sounds like an overheating problem.
Are you working in a well-ventilated area or in direct sunlight?
Check, if you can, the temperature of the motor case.
You might have to take a break more often.
This hot summer has stressed a lot of motors and electronics.
When it shuts off you know it is trying to save itself from burnout.

SOURCE: I have a stihl ts-410 cut off saw. it will start and idle but when i squeeze the throttle it dies. how do i adjust the carb?

if this machine ran ok before this problem,and no one has adjusted the carb,then i would check the crank seals.i have just had this problem.and it was the seal on the puller side,though i replaced both whilst i was at it.hope this helps my freind.

SOURCE: stihl ts 350 super cut saw died in the middle of cutting a brick

i am doing one right now (ts350). I had no spark. 2 problems there. I had to replace on/off switch do to dust making it malfunction. still no spark so I had to replace the Ign. module. got great spark now. It's not cheap either ($226.00 canadian) had to order it from a dealer. Now I have no fuel getting to the cylinder so I have more work ahead of me. I hope this helps if you only have a no spark problem. It's about a 6 on the skill level.

Ts410 stihl saw stopped working

Starting procedure for Stihl.
(cold starting)

Place cutoff saw on floor (flat clear surface).
Hold throttle in, while pushing on switch all the way down.
Hold cutoff saw firmly.
Pull starter handle until saw fires, it should then cut out.
Click the starter switch up 1 click to half choke.
Pull starter handle again until cutoff saw fires up. note: it will be reving because the trigger is loched on, (blip the throttle once) and it should go to tick over.

There should be np need to keep playing with the choke when the saw is warm. No need to lock the trigger when starting warm..

Apart from using the wrong mixture of 2 stroke engine oil and petrol what causes the pistons to be dameged on a ts410 stihl saw

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 )

Hello, i have had my ts410 in a local repair shop ( TSH in Bury) because it stopped working. They changed a spark plug and cleaned the filter and returned it saying it was fixed and kindly took...

It is hard to cause damage to a unit and be in business long. =) If you don't believe the shop that it is in, then I would take it to another shop that is a Stihl dealer with a Gold Certified Technician. I would also like to say that I would blow the fuel tank completely dry and then check the fuel filter. The filter should be dried after it is taken off of the fuel line and it might have some dis coloration since the fuel is mixed with oil. A new fuel filter should not cost very much in either case. Re attach the fuel filter to the fuel line, and add fresh fuel mix. There could have been some water in the fuel tank that would not be removed when the unit was tipped over. Test run the saw and see when it stops running. Is the unit hot? Did it bog down and die? These are things that should be noted and told to anyone that is working on the unit. I hope this helps you.

Hi there; my stihl ts 420 does not start easily

replace the decompression valve. also check for carbon buildup on top of piston. usually when a saw stops on its own after 5 min or so.... the piston and jug are scored and need to be replaced.
