    Reduced-Emission Engine Technology - Caring for Nature
    The STIHL Inc. “Caring for Nature” seal identifies its powered products that are more environmentally conscious, producing zero or low exhaust emissions. STIHL Inc. defines “low exhaust emissions” as being cleaner than EPA and/or CARB exhaust emission standards.

    IntelliCarb™ Compensating Carburetor
    The IntelliCarb™ Compensating Carburetor is designed to automatically adjust the air/fuel ratio when the air filter becomes restricted or partially clogged and maintains the engine’s correct RPM. IntelliCarb™ uses air from the clean side of the air filter to control the diaphragm and flow of fuel. As the air filter becomes dirty and less air is available for the carburetor, the IntelliCarb™ system adjusts the fuel flow to compensate for the decrease in air flow. This is in contrast to typical carburetors that utilize this air from the “dirty” side of the air box.

    X2 Air Filtration System
    The X2 Air Filtration System revolutionizes the cut-off machine industry by allowing air filters to last up to a year, based on cutting conditions. Outside air enters the system in a swirling motion, removing 80% of dust particles. This pre-cleaned air is then routed through the primary and secondary air filters before being sent into the engine. The X2 Air Filtration System is virtually maintenance free and maintains an incredible 99.96% cleaning efficiency.

    STIHL ElastoStart™
    The ElastoStart™ starter handle is a feature of STIHL. It is a starting grip with a built-in shock absorber that helps reduce the effort when pulling on the starter cord. The ElastoStart™ starter grip noticeably reduces the sudden peak forces (compression) normally felt during cranking. The forces which occur at the grip after the first compression stroke are smoothed out.

Rated 5 out of 5 by Best saw on the market Best saw for the money. Great power to weight ratio July 16, 2016
Rated 5 out of 5 by Great saw Muffler screws becoming loose all the time, aluminum gasket gets ruined. I do own 5 of them, ALL have same problem, even better tread gets damaged, ripped out from cylinder.(I do retread and put 1mm bigger screw with high heat and vibration resistant tread lock) and think will have to put tread lock on new saw muffler screws before first use.Other ways it's a GREAT saw, compare to TS400(I had around 20) it's holding up really great. All of them still runs, no mechanical breaks like TS400 had with piston rings, axle bearings.We do masonry and it gets its beating dry or wet cutting. April 26, 2016
Rated 5 out of 5 by saws work well we have 8 ts400+7 ts420s i freshen them up in the winter all very good saws.the last one we got does not use a decompression valve! I question that. but i trust stihl.they are the best we can find February 23, 2016
Rated 3 out of 5 by Muffler issues I own a few of these 420 saws, i have had problems with all of them. mufflers come off within a matter of a month or two. I have tried Loctite on the bolts, also had them worked on by stihl dealers and they break off again. I have been using stihl equip for years but am more than likely done buying these cut-off saws if this flaw continues to be a problem. January 17, 2016
Rated 5 out of 5 by Two thumbs up. This is a great tool. We wish we would have bought it years ago. Starts easy, runs great, has lots of power, blades last a long time. We are cutting a lot of 2 7/8 inch pipe and some 4 inch makes quick work of it. If you are thinking about one get one you will not be sorry. December 16, 2015
Rated 3 out of 5 by Good Saw Except for exhaust problems I have had my 420 cut of saw for 4 years now and the past year i have had problems with the muffler coming off. Bolts come loose from the head. Im not sure if this is new or what. But it cost me money for the down time. Really like the saw except for this. I hope they can fix this issue. September 24, 2015
Rated 3 out of 5 by problem with the TS 420 i own about 15 TS 420 chop saws . i have been having issues of the exhaust coming lose and doing damage to our saws . love the saws but hate the problem costing my company extra money and time while the saw is down. all i say is if you buy a TS 420 take the screws out of the muffler and locktite them . September 16, 2015
Rated 5 out of 5 by champ I am a demolition contractor and I have many chop saws and I by far can say this ts420 I a good move the only down fall is if you do not know haw to start it you will faile I put all my men thru training and we have no problems.....
