Are You Ready for a STIHL?

FS 40 C-E is rated 4.3 out of 5 by 430.
Rated 4 out of 5 by from Good performance. Overall, I found this a fairly reliable tool albeit with a few issues. I mainly use it for edging, rotating the handle so that it trims vertically. This puts the controls in an awkward position forcing me to operate the control lever with my thumb so that I cannot get a solid grip making it hard to control. This is my biggest complaint. I suspect that a stright shaft trimmer would have been a better choice. I intially had a problem with the bump and feed feature of the autocut head. The major problem turned out to be that the string was welding itself to the spool. I found out that there is a problem common in string trimmers of ultrasonic heating. I am not familiar with this phenomena even though I spent a number years as an engineer working with designs involving heat transfer. I wish the user manual had warned me about it. One thing that apparently aggravates this is the strung slapping on a concrete sidewalk or driveway when using it as an edger. I have been carefull that the string hits between the sidewalk and the turf. It has now been working like a charm (being sure that I am running at full throttle while bumping and that the string does not get too short). It has been easy to start and it is fairly easy to replace the string.The worse part of this tool is that it is awkward when used as an edger because it is necessary to turn the motor and control switch upside down.

Rated 5 out of 5 by from Plenty of power This trimmer has more power than I expected. The only con is that I am 6’ and the curved shaft seems a little short, not sure if the straight shaft would be better for someone my height. I haven’t had to respool any line yet, so I can’t comment on that.

Rated 1 out of 5 by from Extremely difficult to fill with line A bunch of engineers got together. They all agreed, "Let's make a great little trimmer but make it an absolute chore to refill the line. Yes. Let's make the human wrap not one, but two strings around the spool." "Great idea" one said to the other, adding, "YES. And even better, when the first line gets wound, let's make it real easy to unwind while we are filling the next one! Oh fun. fun!" And finally, "Let's make the human purchase an entire head instead of just a spare spool or two. That way, in 106 degree weather, standing along the fence line, when they run out of thread, they have to stop and fill the spool instead of just snapping in a pre-wound spool."I absolutely hate this trimmer and this is my second season with it. I am getting rid of it as soon as someone on Craigs list gets sold on the Stihl name.

Rated 5 out of 5 by from Great trimmer Great trimmer. Starts easy. Powerful. Only con is I am 5'7 and I think the shaft is short.

Rated 1 out of 5 by from Very difficult spool wind I love everything about this trimmer except spool wind. Somehow Stihl regressed two decades to a rewind that is so difficult that you cannot do it with gloves and, even bare-handed, it is easy to lose grip on the line. The prior technology is so much better!I’m really disappointed. I hope my dealer will give me credit toward another product.
Date published: 2018-07-03
Rated 5 out of 5 by from Overall great tool I started by asking friends what they recommended and they all said Stihl was their first choice. Checked reviews and reports. So far its been great, easy to start and plenty of power. Next time I need outdoor power tool it will be a Stihl.
Date published: 2018-06-28
Rated 5 out of 5 by from All great features EXCEPT reloading the cord. I’ve had my Stihl for roughly a month and it’s worth every dime. The ONLY problem I have is reloading the cartridge. It’s taking a while to learn how to complete. That slows down the process of completing yard work. So, for now, I am having to buy new cartridges after use. Can you make any recommendations to help resolve my issue?Otherwise, wonderful product.

Rated 5 out of 5 by from This product has great features This is my second Stihl trimmer, and I love the Easy2Start™ technology. I don't consider myself old but at 73 you don't like to crank and crank. This thing fires right up. I also like the kill switch, there's no guessing with a two position toggle switch. This thing is always on and you have to push it to kill it. This is a great addition to the rest of my Stihl power tools.

Rated 4 out of 5 by from Easy to start I have read reviews that were not to good for this trimmer but I have had the FS 40 CE trimmer for approx a month now, use it every week and it has performed to my expectations. It starts easy, runs good and the trimmer line advances with no problems. I run 89 octane fuel with stihl oil mix and I couldn’t ask for a better starting and running trimmer.
Date published: 2018-06-26
Rated 4 out of 5 by from Needs one upgrade to make it better The bump line mechanism has a history of not working right. Change the head to the replaceable string head (the one that takes precut line) and throw the other one in the trash where it belongs.ANY line will work. You DO NOT need Stihl line.

Rated 5 out of 5 by from Perfect lightweight trimmer! Bought this to replace a 15 year old professional model trimmer. As my needs have changed, I didn’t find that I needed to lug around a bigger, bulkier and heavier trimmer, nor do I need the ability to cut heavy brush anymore. This trimmer fits the need perfectly- plenty of power for trimming around the landscaping yet light enough and easy enough to start that the wife can run it if I’m out of commission.

Rated 5 out of 5 by from Stihl 40ce Starts easily usually on the third pull on a cold engine. Lightweight, idles quietly.
Date published: 2018-06-12
Rated 5 out of 5 by from Price was great and High Quality Product I was tired of messing around with my old trimmer, so I bought a craftsman since the price was pretty good. Within a couple of months the fuel lines gummed up. So I was shopping for a Stihl trimmer, and decided for a low cost entry model. I choose this model after reading the reviews and have been really impressed. Starts up every-time. Very reliable and engine has plenty of strength to cut through my tough yard. Highly recommend this unit to anyone.

Rated 5 out of 5 by from This is a really great product !! This product is so easy to use. It starts and runs so easily. A pleasure to operate in all ways. I bring it back in the house to my spare room and it has no smells. Was considering going to a battery type but now I'm glad I didn't . You will love this weed eater. Flechers were fantastic also, they stayed open for me and had one ready to go when I arrived very close to closing time. They took the time to make sure I knew how to operate it.

Able to leap tall buildings in a single bound!Seriously, it starts easily, idles well without stalling makes plenty of power for the task intended. You couldn't ask for a better tool for the money

Rated 5 out of 5 by from Gas trimmer that actually starts Always used battery trimmers because gas trimmers were hard to start. This trimmer starts on the first or second pull. Not crazy about string trimmers so I added the plastic blade attachment.

Rated 5 out of 5 by from extremely lightweight, and easy to use for an old man, suggest adding the strap. This tool fit my needs and does the job I expected it to do, very lightweight and easy to use.

Rated 5 out of 5 by from Very Easy to Use Over the past 20 years I have used all the "on sale' cheap brands. The Stihl trimmer is well worth the small difference in price. It starts great, cuts even better. Very easy to refill the line. I love it. I should have bought it 20 years ago when I got my Stihl chainsaw! -KB

Rated 5 out of 5 by from This trimmer is a great value This was purchased to replace an FS 52 curved shaft trimmer that gave me many years of service. I bought a gallon of MotoMix with it and doubled the warranty to 4 years. My local dealer was very helpful in choosing the correct equipment for my needs. This trimmer is easy to start, has plenty of power and works well for my needs as a residential homeowner. I have owned this trimmer for about a month now and am very pleased with every aspect of it. If you are considering another brand such as those sold at a big box store, do yourself a favor and visit your local Stihl dealer. You may spend a little more money but your equipment will last much longer.

Rated 5 out of 5 by from Product is fine, service somewhat lacking. I purchased my FS 40 CE after seeing the rating by Consumers Digest. I chose Big R as my dealer because it was close and convenient. The young man who assisted me said they did not have any assembled so I waited about 30 minutes for the "Free Assembly." Prior to this I always took items home in the box and assembled them myself. I took the trimmer home and starting using it the next day. I immediately noticed the line was not advancing like it should as explained in the manual. I kept using it but would have to stop and unscrew the cap, remove the spool and manually advance the line. After removing the cap and spool and manually advancing the line about fifteen times, I removed all the old line and loaded new line on the spool. It now works as it should. Apparently the "Assembler" wound the line on too tightly preventing it from advancing. It starts easily, is lightweight and cuts well.
Date published: 2018-06-03
Rated 3 out of 5 by from Too short for a tall person, most likely a good product otherwise the vertical length from the throttle handle to the cutting head is too short for anyone taller than 5 feet 10 inches. I am over 6 feet and had to been over at a awkward angle which resulted in severe back pain after 10 -15 minutes of use. The equipment worked fine and would be good for small yards cutting primarily grass. So at the store hold the throttle and it the cutting head rests on the floor and you do not need to bend over it should be ok for you

Rated 5 out of 5 by from Works better than my cheap one I have an older one that still works but would bog down while trying to weedeating some parts of my yard. It might need a little adjustments though as it takes a few pulls for it to start but it stays running unlike my other one that you have to keep giving it gas til its warmed up

Rated 5 out of 5 by from Best Trimmer for Your Money. It’s been about a month since I bought the FS 40 CE. It’s an excellent trimmer. Starts very easy every time, has Good power, handles easily and cuts anything in its path. The trimmer is made well and has a solid feel. I’m very glad I bought it. It has performed well each time I’ve used it. Take care of it and it will last a long time.

Rated 5 out of 5 by from Buy No Other I use to buy a troy built trimmer about every other year from Lowe's and I'm hear to say I will never ever buy troy built ANYTHING again! This Stihl trimmer was 50 dollars cheaper then troy built and more powerful, never balking down. The Stihl never clogs and gets tangled in high grass like the troy built because it maintains power to eat through the job. Trimmer head design, comfort, power, weight, cutting ease, and dependability make me wish I had bought a Stihl years ago. I live in West Virginia and I cut a .7 acre lot with no trouble on a hillside! Buy one today!

Rated 5 out of 5 by from Easy start - Easy use I love the Easy start feature. It starts with very little effort on the pull cord. It also does a great job cutting weeds and grass. Weeds and grass do no wrap around the head as my last weedeater did. So I don’t have to stop periodically to clean a bound up head. I have used the weedeater 4 times so far and have been very pleased with the performance.
