Thanks for watching. I was asked to make a video showing how I would replace a broken trigger on this style of trimmer.
What a savior you are. I just took mine apart today. I was trying to see if the Kombi hedge trimmer would work. I don't think it will. I went ahead and took it all apart and gave it a good cleaning. The trimmer has been setting for about 2 yrs with 100% gas in it. I didn't think it would start but it took right off on the 2nd pull. I was having trouble with the trigger installation but after watching your video, I think I can get it back together. Thanks again.
no problem and good luck
Got a quote from a stihl shop to the replace trigger...$120 to $130...thanks for this...paid $12 for the trigger an done it myself...🤙
Good to hear and thanks!
Getting about that time of year here in MI so I'm bringing on your informative how to video's.
nice, hopefully everything starts for you, thank you Michal Fougerousse.
Perfect. Thanks. Couldn't figure how to set the spring right by the trigger. Works perfect. Even have an extra screw left, so I know I did it right!
no problem
Great video very well presented and helpful advice. Congratulations from Aotearoa New Zealand ❤
Thanks for watching!
My son loves watching your channel. He wanted me to comment "good job" 👍🏼
Thank you Kyla Garner I appreciate the support from your son!
Update on my latest chainsaw cleaning protocol. Exterior with power washer, then disassemble, Super Clean and scrub with parts washer brush and toothbrush, rinse using garden hose with sprayer attachment, then finish up with compressed air. No harsh chemicals, no fuel/oil mix. So far, so good! 👍🔧🧰
Nice work!
INSIDE HOUSE GARAGE Thanks! Little by little I’m figuring it out. 2nd day this year cleaning stuff outside. ☀️
You clean a chainsaw with compressed air, carb cleaner and paper towels. A pressure washer, really?
Mike Spain Absolutely, for the first, exterior stage! Pretty soon I’ll be doing equipment cleaning in batches so I only have to set up and break down the pressure washer once for every few machines. Yesterday I got delivered to me a batch of 3 chainsaws, 3 string trimmers and 1 hedge trimmer - all free and all filthy - that had been sitting in a basement for years. Pressure washing will cut the time down by at least 20 minutes on each piece and then I’ve got much cleaner equipment to start working on. In the case of large pieces like generators, lawnmowers, lawn tractors and snowblowers the time savings are MUCH better and I’ve got a yard full of them to work on as well. I also have an ultrasonic cleaner for carbs, etc. I’ve used carb cleaner, brake clean and gas/oil mix before. Not a fan of breathing in the fumes. Super Clean works just as well with no harmful fumes, etc.
I would like to offer one important tip. When reassembling plastic parts, NEVER start the screws with a power tool! Put the screw in the hole and with a hand tool apply firm pressure and turn the screw BACKWARDS until you feel it drop into the previously cut threads. Make a couple of turns until the screw is fully engaged. Then you can run it most of the way down with a power tool. Tighten by hand and don’t over tighten. Failure to do this can result in the steel screw cutting new threads into the soft plastic. This rips out the original threads and leaves you with a stripped hole that you have to attempt to repair. 30 plus years of working on auto plastic dashboards and 10 years repairing copiers and printers has taught me valuable lessons about plastics. A trick for removing stuck Phillips head screws that have rounded out is to use a pair of diagonal pliers (wire cutters) with the handle in line with the screw. Firmly grip the head of the screw and twist.
thanks for the tip, I'll be sure to do that from now on.
Hey bro great video👍👍. In my opinion this was a simple repair that anyone could do for themselves. Everything you do first you just have to do in reverse while mounting back any piece of equipment.
Very true, thank you Ramadin Sookhoo.
Classic "Do as I say, not as I do" moment. :) Even so, it's a true testament to only using ethanol-free. Unfortunately it's not available to everyone here in the states.
thank you The Lawnmower Lady, and yes that's a real shame.
Being along Lake St Clair, the boating capital of the US, many stations sell ethanol-free recreational fuel. However, after gumming up my own FS 45, I replaced the carb and use premixed 50:1fuel in my two-cycle equipment and Rec gas in my 4-cycle equipment. No carb issues since the switches.
it certainly seem to prove the point about what ethanol can do in gasoline. thank you George Mazich.
awsome my tigger jamed on me last week tryed to fix it.
couldnt, untill i found this video
thank you because you just helped me out big time now i can repair it
Glad it helped
Thank you for that showing of how to replace the handle on one of these Stihl trimmers I have an echo SRM 251 I have to replace the handle on that one soon
I know right, Echo did the same thing, and the trigger is always breaking. thank you Turningwrenches85
@@INSIDEHOUSEGARAGE your welcome sir
Great video!
Thanks!
Great video, changing the on off switch would be similar. T27 screwdriver
A large issue is the exhaust screen blocking with carbon, easily cleaned buy burning off the carbon build up. 15mm Socket
you are absolutely correct about that.
I had an FS38, and did replace the trigger at one point. That trimmer was a real pos!
I've heard that about them, did you ever have to service to get it working right?
Thank you
You're welcome
That little Spring in there is a tricky So B.
yes it is.
Isn’t it amazing after all we preach, we are just as guilty haha. Thank you for the upload. Seems like with a little run time and idle increase it’s ready to rock again!
you are absolutely right, And yes, after a bit more running, it did seem to improve, even on the old Fuel. Thank you Freedom mowers.
Best part was the view from the side that shows how the safety bar and throttle trigger connect.
thank you, I appreciate the insight,.
Was that youtube’s auto reply? You didn’t actually show how the safety bar and trigger connect.

I love sthil, my grandpa has had one of their blowers and it starts first pull and I never had a problem with it
I know right, their stuff is pretty good, when compared to other brands.
What about Husqvarna ? 🤔 my family has and lives with husqvarna equipment 😅
Maybe comparing stihl equipment to husqvarna equipment would be a thing to see the pros and cons on both 🤔
@@lucasbergfors9446 I love husqvarna once I save my money I'm going to buy a husqvarna trimmer and edger
@@warrensoutdoors5964 dad and i got a 1970 Norlett mulching mower, Husqvarna LC 247 SP self propelled mower, Husqvarna 345FR and 1999 Husqvarna 252RX trimmer 😄
So I’ve followed the installation process but on start up my STIHL won’t idle. Somehow the cable is not going fullback to the idle extension and for the life of me I can’t see what I’ve done wrong. Any suggestions? My unit is an FS 55 but the identical trigger set up
sure, look at where the cable wraps around a half arc piece of plastic and see if it's not on it.
I also noticed the trigger assembly on the cheaper stihl's does appear to be pretty fragile.
that was my thought too, It would be interesting to just buy one, and see how it stacks up to the OEM one.
Yes, it is cheaply made. I was setting the trigger back into the notches and 1 little plastic peg broke and now I'm at a loss on what to do. Is it fixable or must I replace the whole bottom shroud? 😢
parts like a trigger or any other plastic parts, i'd not mind using the cheap parts but for the essential parts like carb, i'd consider using the oems
that makes sense to me Adam the Lawn Guy.
I work at a hardware store that is a Stihl dealer and they recommend their tools to use a 50:1 fuel ratio. I'm not knowledgeable enough to know whether or not 40:1 would be harmful to the engine but I just thought I'd drop this info in a comment.
Nope, 40:1 being used in a 50:1 engine isn't harmful at all, You just have to examine the spark arrestor screen more often, and most people never do. I never realized it, but the difference in the amount of OIL between 50 and 40:1, is a tiny amount. Besides, if you use what they recommend, 50:1, it's meant last X amount of time And to run at 40:1, just means it's going to get last a little bit longer. They just want you to buy their stuff every few years, not every decade.
you are absolutely right about that.
thank you mine just broke under warranty lucky 4 years ,,,,,its a cheaply made trigger if you ask me for a good brand like STIHL ,,,,plastic in some areas is not very good always ,,,,,,thanks for viewing this to us ,,,,,,,
no problem bug Den.
On an item like that my first consideration given the price is similar is which one can I get quickly which one is in stock which one can I have in the next two or three days versus which one is the cheapest
that makes sense.
How can I align the plastic cover? It’s still somewhat loose on mine
that I'm not sure about
How do you clean dirt and grease off things like this? Ive had yard equipment that is entirely covered in the stuff.
It depends on how bad it is, But I use either an orange based cleaner, old gasoline, or a store bought degreaser.
👍😎
thank you Robert Mailhos
@@INSIDEHOUSEGARAGE you are welcome young man 😎
The notches the trigger sets in, 1 broke, anything on how to fix it or do I have to replace the bottom plastic shroud?
unfortunately my best advice would be to replace the broken piece. However I don't ever use the notches since I hold the trigger to start it.
@@INSIDEHOUSEGARAGE the trigger won't stay stationary without being in those notches.
Wish I had seen this video a year ago before I removed all the trigger safeties as it was bear to reassemble.
I think I might have done the same thing years ago as well and yes it was pain to deal with.
Just worked on one. Had to do some cleaning in the kill switch connections.
Now the safety lever does not engage. It does not affect the trigger working and the weedeater running.
Why at do you think happened to the safety lever?
Piece break off that the shaft hits to raise it?
Not locked in somewhere?
I hate to say it, But I'd have to see it in person to figure out why.
@@INSIDEHOUSEGARAGE Thanks for your reply.
I watched another video snd noticed it is supposed to have a spring on the safety lever. This one does not have the spring. I thought the shaft had pushed it up. I don’t know what happened to it. The lever was up before I dissembled to clean the switch connection. I don’t remember seeing one when I removed the lever to see if maybe I had reinstalled something wrong.
Thanks again.
Evidently I also need the spring that goes in the trimmer head, so U cam bump it to let the line out. It does not have one. I have to pull line out by hand after working the head.
Have a few more weedeaters.
Think I can remove a spring from a Fs45 Stihl and use it in the Echo? May very well be basically the same heads with a few different parts for installing. I would think the heads are very possibly the same.
Even, if they are not, I wouldn’t think that spring would have to be the exact same.
This trimmer looks brand new
I know right, it's in really good shape.
Having difficulty getting the piece with the switch lig
ned up with the trigger.
patience is the only thing I could say. The other thing , is are you sure, it lined up, like it's supposed to, and not where you think, it goes.
I would have sprayed some Amsoil silicone spray on that trigger before replacing the cover.
awesome video, I have an fs36 Stihl trimmer do you know anything about them?
thanks Will's Small Engine's, from what I've seen, they are pretty much the same as this FS45 but with a little less power.
Which one is better? Echo or Stihl. I've used my echo weed eater (pas 225) I love it. But never really used a stihl I've used my granfathers but it was a short time. I just want to hear your opinion.
thanks for the question, I'm going to compare them by price first. In the $200 USD price range I like the echo straight shaft, But for the larger and more powerful trimmers, I like stihl.
@@INSIDEHOUSEGARAGE Thank you
My existing trigger didn't have that spring in the housing. It appears to rely on the carb spring to reset.
interesting, it's the same model as the one in the video then?
@@INSIDEHOUSEGARAGE Yes, same.
I’ve said it before and I’ll say it again. You get what you pay for. I would pay the extra money for the better OEM part.
thank you William Snow.
do you think you can make a void on how to retap a cylinder head on a mower and how to put new self propelled cables in i have a .masport president 6000 and can get parts but don't know how to fix if thanks
probably but I don't have the same model available in my area
@@INSIDEHOUSEGARAGE maybe something similar?
possibly
What would you do if you realized that the clips holding the trigger in are broken? Try to find a new lower plastic cover?
for a customer yes, for my own, I'd redneck it. Plastic welding, or using some super glue and baking soda
@@INSIDEHOUSEGARAGE Ohh ok thanks. The two on the engine side are super weak. Long story short picked up a fs38 today that wasn't running. Accidently dropped it moving it, I believe that's what ruined the clips. Couldn't figure out how to get the trigger spring back in (watched your video) then realized the clips were broken. It was free so I'm going to wait until another fs38 becomes available or find parts for cheap.
Thanks
just ran into a adjustment limiter problem on a 455 rancher i removed the limiters and its back to normal
where was the limiter located at?
@@INSIDEHOUSEGARAGE on the carburator adjustment screws there was a metal shim causing the screws to bottom out prematurely and after removing them i was able to fuly adjust the carb
Oh yes, I forget they're there. thanks for the update.
Show a video of you converting that into a straight shaft
Please
if I have the stuff I need to do it, I would but I don't at the moment.
when ready.
On my fs45 sorry forgot to add that
Or during transport if you don't want it to break just put the cruise control lock on
that's also a very good choice to keep it from breaking, thank you Small Engines 101
5:06 having same problem plus one of the clips is broken on bottom of throttle bracket
that'll make it a bit more challenging
Come to think of it, it was the safety lever I replaced.
that makes sense to me, the trigger design is definitely a weak point.
Greetings 🙋♂️🙋♂️🙋♂️
Hello 👋
How about fs38 please
should be the same
Well i don't think it really matters all though usually a oem one is usally a good choice etc.
that makes perfect sense, IF the price difference is small enough then, I'll choose the OEM part, But If it's a 50% difference, I might go cheap
@@INSIDEHOUSEGARAGE yep as long as it works out for us etc.
I'd get OEM and that way if it died I could go back to the dealer and see what was what. I've got a 440 magnum and went back up with an OEM top end. $350+. Blessings!
thanks Lewie McNeely
@@INSIDEHOUSEGARAGE Sure!
Stihl ms250 and most clippers take 50:1 not 40:1 fuel mix
sure do.
I legit thaught the fs35 is the same thing as thefs45
they are so close, I really can't tell, I don't they sell the 35 anymore
cheap, specially thinking that the original oem one is the one that broke in the first place.
you make an absolutely great point.
Shame on you, lol.
