How to put together a Stihl TS 510 concrete saw

SOURCE: 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.

SOURCE: I have a concrete cutoff saw made by stilht it

clean carb and tune up

SOURCE: need to know belt size fo the stihl ts400 concrete

You should go to a Stihl dealer and ask for the belt for a TS 400 Cut Off Saw. The belt is ribbed, you should only put on a Stihl part to replace the belt and make sure the belt is under the correct tension. When you go to the Stihl dealer you can ask them to show you how to make sure the belt is under the correct amount of tension.

There could be a few problems. Check the air filters and make sure that no holes are present in them. Then check to make sure the unit has compression. A general check of the compression for a Stihl unit is to hold the unit up by the rope and it should hold itself up. If it slips down really quick or if it does not hold itself for more than a couple of seconds before the rope starts coming out, then the unit is low on compression and will need a new piston and cylinder.
Also another thing to check is the carburetor. With the new fuel with ethanol/methanol in it, it can damage parts in the carburetor. The sealant that went over the welch plugs will come off and it will flood the unit out because there is no regulation of the fuel going into the engine. You can try putting new sealant, such as clear fingernail polish over them, and see if it holds and will regulate the fuel correctly. If the air filters have holes in them then the low compression could be caused from dirt ingestion and it could have caused wear on the main bearings. You can check for bearing wear by seeing if the flywheel or the clutch will move up and down and sided to side. If this is the case then you will need to purchase a new unit.

SOURCE: not getting spark when starting

[email protected] HI GRYDERT your problem could be your on, off switch. This might sound funny, but switch the on off switch real fast several times, then see if you havee fire. If not check your spark plug. If you have a n
ew one try it. If that don't work check the connection at the plug to be sure it is makiong contact with the plug. If all this does't work you will have to go inside to the coil. They don't usually go ba d but it could. But first check to be sure it isn't grounded at the small wire from the switch. Good Luck.
