@H Sy 😂

I've spent most my childhood around saws and logging since about 5yrs old (giant wood beetles use to be my worst fear😄). Nowa days I just cut trees and limbs out in the yard occasionally. Even out there in my yard I run out of gas and need to refill the saw before it cools down, I'd imagine this isnt just a unique problem isolated to my yard and home use. Who waits for the saw to cool down every time they need to refuel🤔. I bet even Jason Vorhees got a bit of fuel in the eye every now and then💀

I’ve run a landscaping company in arizona for 35 years hundreds of refills a week and know hundreds of companies doing the same thing. If we had to wait for something to cool down or run completely out of fuel nobody would make any money and I’ve never heard of anything catching fire, blowing up when refilling ever.

@@moneyandtimefreedom3352 It's got nothing to do with health and safety, it's about making money. They're creating a problem that doesn't need fixing simply to cash in!

@N A Wow....great tip. Like a hot radiator cap

where is the money in that?

All my Stihl saws do this

The dilithium crystals cannot stand the strain!

I don't know what to say, I've been working with saws forever and neither myself or the hundreds of guys I fall with have ever heard of this. At least I've never heard them talk about this problem. We don't refuel until we're almost empty anyway so that may be why we don't get fuel sprayed on us.

Then you could pull over next to the house and have your wife run out and hand you a cool drink and fill the mower. Great idea!

And one of the kids could make impact noises 😂

I'd like to see you change 4 wheels in 6 seconds.

Cup or Xfinity?

No you are supposed to take it apart and fix it anyways....

That's a good one, maybe that's why a engineer gets paid twice as much...........

Government motto. Find something simple and complicate it.

Hey! This old design worked flawlessly for over half a century and hurt basically no one. Let's change it for fake liability concerns until actual liability lawsuits get too big to deal with!

You know I could take offense at that remark.

good one

So true, Jeff 👍

THAT IS CALIFORNIA FOR YAH...??????

That would make sense as it wasn’t an issue w/ the cap but the fact that the saws used to have an internal vent that would allow the saw to vent pressure and thus when you flew on helicopters w/ the saws they would sometimes leak or they would leak fuel into the saw compartments on the rigs or the ground. Not much of a fire hazard to get burned because of it because it was so slight. Certainly Not like the geysering issue. Thus the anti pollution rule caused Stihl to make the saw a sealed system to meet regulations, plus the new cap can’t be cross threaded and leak fuel that way. This would be great.

Many small engines pressurize the tank to pump fuel

@@heathhunter5306 HP racing 2 cycles pressurize the tank to force more fuel into the combustion chamber, as the tuned pipe also pulls the fuel in.

@@bff1316 pressurized fuel is utilized to eliminate the need for an actual pump. All expansion chambers are tuned to match flow and return pulse delay time, to work within certain rpms. All exhaust has a pulse, though, tuned or not, and that is also a type of diaphragm pump, which can also use crank pulses. My biggest point is that tank pressure is just a fact of life on small engines, and being aware of it is 90%the problem, not just look for the first entity to blame...... that's also not to say that I dont think carb are morons, and EPA, while doing good, does some pretty stupid things as well.

Thats the EPA and OSHA doing what they are made to do: 1 step forward, 50 steps backward

Yeah :D I saw it to but those plastic gas canisters always leak at the cap, not the fault of the Motion Pro thing i think.

I was just about to post the same comment

Same

The problem with threaded caps is they get tight and then you need you’re saw wrench to take it off and I don’t wanna have to go get that every time I wanna fuel up. I personally don’t have problems with the stihl gas caps now

@@romankevin3884 that is because the vapor lock and overfilling the tank..

@@romankevin3884 I carry a saw wrench in the pocket of my chaps all the time. I have two reasons. On my some of my saws I may need to unscrew the cap and second I've never had it happen to me, but it has happened to other guys. While bucking a large pine my buddy got his saw stuck. It was getting late and we were low on gas. So we used my saw wrench to unbolt the saw head from the bar and took it home so no one could steal it. I hate the new caps. I had one on the reservoir of a Stihl poll saw. I though and it looked like it was good. It wasn't and I spilled chain oil on the drive way of a friend. Personally I'd go back to the caps they used on my 031s and 045. They were molded with a tab on the top. If you got in a jam and couldn't unscrew it by hand a pair of pliers worked.

Michael Fresh yeah you do have a point but you will never see me wear Chaps and it would poke me in my pocket

I had this happen on a Stihl weedwacker with the threaded cap

I would say that its a 'plan for any scenario' kind of statement. You never know what kind of whacky things people get up to.

It could be a west coast thing

Exactly what I thought when he said that. Instantly went to the comment section to find this lol

I climb with fuel bottles as does my whole crew. Time is money. Some days a guy will spend the whole day in the tops, tranfering tree to tree without returning to the ground. I still think this fuel system is lame and unnecessary.

A lot of times i had to refuel at the top of a tree i just sent the chainsaw with a rope down to my co-worker who would send my secondary chainsaw to the top . This way i didnt put a lot of stress on my chaisaws allowing always one to cool down

Perhaps you don’t have a late model still?

@@chrisc9611 I have two late model saws and never had that problem.

My ms211c has this problem

Got an 039 Stihl. Fuel vent line came off. Not fun

I think its a problem specific to firefighting since they are running the saws in high heat environements. The way i understand it, the fuel starts to vaporize in the tanks and builds up a lot of pressure. I dont think its a problem for use outside of high heat environements

If it's under extreme pressure but you can't tell, once you break that seal it's spraying. Doesn't matter how slow you open it. I've been using saws 30 years and was unaware of this potential hazard until 2 weeks ago. Surprise! Recovering from severe burns now. Nothing in the owner's manual about this.

@@class5bodyworks just got my first saw at 24.. I got sick of tasting gas and learned to slowly open the cap after running it hard. I've got the screw type cap too. So it doesn't matter

That's what I was going to say I think they need to line up the inner with the outer lock cap. Exterior male slot to female recess inner.

I thought the exact same thing

exactly

Agreed.

How come we can see that on the vid and he cant? Took a second to figure that out. We will chalk it up to on-the-go video tapeing

I've never filled mine after running a half tank I just know about how many cuts I can get every tank fill equals a bar oil fill run it to empty . I have a ms250 an havent had that issue . The only issue I had was when I cleaned the air filter I put it back together started it an when I was done the cut off switch didnt work. But it's being fixed.

Mr. Anonymous ive had the same issue. Im a stihl tech and ive found some of the air filters/housings for the filters can push the metal piece that contacts the stop switch wire out of place and causes them to not come into contact with each other to complete the circuit and stop the saw. Also with alot of the saws ive worked on i find that when i open the gas caps this happens for me. Not necessarily strong enough pressure to blow off the cap entirely but enough where it gets on me and has blown in my face a few times.

@@nathanlorenz2950 yeah I cleaned the filter an put everything back together its started just couldnt cut it off

Every time you run your saw out of gas you're also running it out of it's lube oil, proper procedure is to refuel, re-oil and sharpen chain at every opportunity on fire line, running out of fuel while falling a burning tree can put crewmembers in danger.

@@explore7151 well I don't run it till it cuts off I just know how many cuts I can get till its damn near empty their is still fuel in it just not bone dry or a half a tank . On good size logs I can make 4 cuts smaller ones I'd say more like 8 then smaller than those it goes up but I dont run it till it cuts off .

That's a good idea. Twist to unlock, then only as you move the cap away from the tank is it allowed to vent.

I have never experienced it even hard about it and I have been running them over 30 years. I would assume the first day of class they told them not to stand at the edge of the fire line and refill your saw and set some kind of like 50-100 yard limit to how close you can have you fuel can to the fire or how close you can be and refill your saw. It doesn't seem to bright for then to be refilling their Saws close enough for it to be a problem. Any fuel spillage from either the guyser effect or plain accident should be far enough away to have evaporated by the time it could cause an issue.

Lol I noticed that

never jinx yourself..... :D

Was about to comment same thing lol

Just a small amount though. I think it would hold 99% of the fuel if tipped over.

Teflon tape teflon tape teflon tape!

Throw a rag over it and open slowly. Idk if wild land guys carry loose rags but the average guy has them and probably doesn't have $100, right?

as a normal user i could see where there would be no issue of a geiser but in my 13 years on a hotshot crew (lead saw for 5 years) i have personally experienced it twice and that was while cutting during 100 degree plus day and ran probably 6 tanks cutting hotline. Its very rare for a geiser to happen but they do.

Yep, used several Stihl with these caps and never ever an issue.

VB just text the same !!! Never had the problem !- Altitude ? I open when empty or near empty ! I do unscrew it n hear a little air suction ! But THEN I remove the cap ! 30+ years !! Wrangler Guy should play w/ it first n try it out ! Then make a vid. ! 👨‍🚀🤠

Sadly some folks aren't smart enough to safely and successfully operate a fuel cap.

Calling guys on the fire line reckless rofl gg sten

@@mathewdasilva4421 some are sadly, to the detriment of others … Don’t be one of them. Serve carefully.

As well as "don't stand next to a fire while refilling your running chainsaw"! Someone needs to ensure the person training these people had not just an education, but the common sense enough to use what they learned. Book sense without common sense is useless.

i am with you; i finish my tank!!!

Often times when a chainsaw runs out of gas (dies) there is still a little fuel in the tank just not enough for it to pick up

@@asdasd-ni8eg you should wear safety glasses

@@asdasd-ni8eg in all my years cutting i have never got a drip in the eye i would be more worried about saw dust and wear eye wear

Good to know safety sam. Although you need the ones that have foam to stick to your face. That fog up because I find things generally go in on the rebound when wearing those pos. But in all fairness i think you missed the point.

That would be too smart for the engineers.

hey, they are not paid to come up with simple solutions

To easy has to be engineered to nasa standards.

Tom, time to get with a fabricator for someone with a 3D printer and make you a ton of money.

it would cause the same problem of gas spilling around. The moment you release pressure the air will seep some gas with it. If you would use a pressurereliefvalve with a fine sieve it could work.

Same. Too many gimmicks on Stihl saws, gimme a Husky any day.

That's what i was thinking looks like the saw will lose almost half it's capacity

It will not loose almost anything! Guys, this is not solid product. It's hollow inside... :)

@@pallermo where can you purchase this Im in Australia

As I understand it it wasn't a big problem until they started using those quick open caps. With the old threaded caps the pressure would start leaking out before the cap was entirely unthreaded giving it time to to equalize. The quick open caps are however staying sealed until they are free and the pressure is violently released. Even then it can't happen all that often or it would have been fixed before they were released to the public. But that's just my thoughts on this and I may very well be wrong about it all...

ive had it happen to me multiple times while cutting firewood....saw has to have been running for a while to happen, like running temperature but it does happen.....more often then i like

i just run it till its outta gas that way my saw doesn't experience that and if i let it set the gas won't go rancid on me in the tank.

@@sailplaneFan707 awesome but if your doing it for a living or fighting brush fires or wildfires, u dont have ur jerry can with u....so any chance u get to top up u do. Its just more efficient that way. professionals top off their tanks everytime they get. like i said this doesn't happen to me all the time but its happen more then once.

@@ximer21 i said its good for fire crew and smoke jumpers prison crew stuff like that

It is a defective cap. They get hot from the proximity to the engine and don’t vent to equalize atmospheric pressure from inside the tank. It’s a bad design, they know it and haven’t done anything to improve it, you know like just putting a normal twist fit cap back on there

Happened to me a couple weeks ago except mine lit up. I'm currently recovering from severe burns. No mention of this hazard in the owner's manual

😂

thats a good point! it doesnt ever happen if the saw is empty so the pros totally would think this is made up. this winter i will fill my saw in the cold then take it inside to let it warm and the take it outside and open it. if it happens you will get a gold star

​@@MrGarwood420 I have no idea what your reply to me has to do with my reply to Lance Surgeon's post. Also you should have typed "they're" not "their". Kinda makes me wonder about your IQ level.😉 I have no desire to get into a religious discussion with you so I'll fill you in on a little world history. Jesus of Nazareth was an actual person that existed. Try reading a history book... or two. Now whether you believe in God or believe Jesus is the son of God or isn't is your choice. You have the right to believe in what you want. That being said you really shouldn't base a person's intelligence on whether they believe in God or not. After all Schrödinger, Marconi, Isaac Newton, Louis Pasteur, William Thomson Kelvin, Michael Faraday and many other highly intelligent people believe in God.

If I remember the tank vent has a one way valve, let's air in but nothing out.

Yes you are right my saw floods all the time in heat.No vent on fuel tank.

they are also not allowed to vert those unburnt fumes in to the atmosphere. I would think the EPA and CARB have a bit more pull over the firefighters.

I really have to think it's the no vent plus the 1/4 turn fuel cap. With a normal fuel cap the tank has chance to vent slowly as the fuel cap is unscrewed. I wonder if the solution wouldn't be just to use pressure venting caps like the safety style you can buy for car radiators.

@@allalphazerobeta8643 I have seen tank pop like a can before.

​@@andrewyork3869 Radiator style caps have over pressure releases, of course that could release fuel but better a small controlled release than all the fuel going everywhere. A Hose could also direct the fuel into the carburetor, kind of how Marine carbs do when the floats stick. That Does sound like a problem caused by not leaving any head space in for thermal expansion of fuel in the tank. Maybe, Stihl needs to adopt a head space tank usually within the main tank, a few cars use. (Volvo 240 used this) They have a tank inside the main tank that has a small hole into the main tank. The idea is to make it people almost impossible for people to over fill the tank. It makes it so there will always be a bit of space in the tank for fuel expansion. The primary reason for this is if you fill the fuel tank completely up (By being knotty and topping off) in the morning and then park the car within a few miles. You'll have cold fuel in the tank and it will heat up heat and expand during the day if the tanks was near completely full or put another way the tank doesn't have enough space for thermal expansion of the fuel so when the fuel heats up the tank leaks fuel through the fuel vent system. (Possibly also damaging parts in the EVAP system but definitely a fire hazard) Now, you know one of the reasons cringe when I see people over filling their fuel tank at Costco, Especially in the morning. Having some head space in the tank is also a good idea if the tank gets crushed in a collision.

When in doubt blame the government.

@@Deere2154D The government did cause the problem when they mandated non-vented fuel tanks on everything. When they expanded a regulation that addressed a large problem with vehicles (where the fuel tank is separated from the heat producing engine) to include the almost inconsequential impact of lawn hand equipment (where the tank is nestled with the engine) they created this mess, as well as created a safety problem. Another case of government over reach. Like most things, there is a limit to where something is beneficial. After that it can become toxic.

@@Deere2154D The government is who made the current bullshit permeation and evaporative emission requirements. So yeah it is their fault.

#defundthealphebetagencies

It's some sort of regulation for sealed systems now.

gabriel ethier the vent only allows air in, not out. You need slight pressure in the tank to maintain proper fuel flow.

@@jacobforrest7894 tanks need to vent out of the tank as pressure builds up and needs to release.

I’m a certified STIHL Tech and have repaired/replaced likely hundreds of vents. Every one of them is a one way valve allowing air in, but not out.

@@jacobforrest7894 When the gas inside your Stihl chain saw fuel tank heats up it creates pressure inside the tank. ... The tank vent cap sits on top of the fuel tank and allows these heated gasses to escape. The tank vent cap needs to be cleaned occasionally for the carburetor to work properly.

The only problem isn't just the venting gas. The system is also easier, don't have to worry about losing the cap in the grass, don't have to worry about the cap getting dirty when it falls and getting dirt in the system, don't have to worry about the ¼ turn cap breaking as they often do, and it's faster to refuel.

That's what I thought. If you've got to refuel, back way out of the danger area! Oops that would require common sense!

Fire fighters hear burning trees.

Thank you haha. This guy is something else. Used to like his videos but hes got some douchery content now. Also arborist dont refuel while hanging in a tree.

Very Westcoast

exactly!

Because sometimes you need to just top off.

Because guys will top off the saw before its empty. And even saws that are low enough to bow longer run will have a few ounces of fuel left. Does not seam like much but under pressure and in thr wrong environment it would make a heck of a fire ball.

rushrule1 out gas meaning there is not enough for it to run. Depending on the angle your cutting and how the fuel siphon hose is oriented within the fuel container. Kind of like a car when low on fuel. You turn fast or parked inclined at a certain angle it will trip the low fuel light. Well in this case with the saw the angle will make the engine sputter or shut off. Tupac is still alive 🤫 WestSiiiiiiiiiiiiiiiiiiiiiide!🤘+🤞=🖕

It's a solution to a very niche problem. Very few of us are wildland firefighters, but those guys being able to work properly is a lifesaver for hundreds or thousands of us. The same system is used in NASCAR for the same reason.

You can't it's a 1/4 turn cap and the pressure is pretty intense.

@@mattvonbargen7653 I've got two of them and after taking the cap off too quick, I learned to do it slowly. And not remove the cap when there's too much hot gas inside.

@@ArcolaBridge are you doing this slowly everytime including during you 18 hour shifts as a wildland firefighter, refueling dozens of times a day? That's the entire point you can't remotely have this happen, at all, especially on a fire.

@@mattvonbargen7653 it's a chain saw, there are many things you Have to do all the time the same way or the saw is down or worst case you are hamburger.

Matt Von Bargen yes no matter the situation,you follow the safety rules on a chainsaw or you will see a doctor.

My concern with a pressure release idea would be you would have no control of when the pressure cap blows meaning it could blow a fuel air mix out at a very bad time!

In a vehicle coolant system the pressure cap is at the highest point in the system, and usually diverts the excess pressure/fluid back into the system, or diverts it safely towards the ground. With a chainsaw the filler cap is on the side, so it would just let fuel squirt out!

@@danwhite268 Exactly. Due to the fact that chainsaws are used in every possible orientation, a pressure relief valve is not a practical solution, no matter where on the tank it is mounted, for the reason you stated.

jimsiggy Stihl would never change to this design. I promise.

I feel like it's not really a problem with the saw so much as it seems more to be a problem with the environment the saw is in. I'm not engineer anything like that but it seems like "the heat from the fire" is making the gas turn into a pressurized vapor and that is causing the gas to come out the way it is, but I'm only presuming this from listening to what is happening. (I could be wrong also, I'm just saying what I think.)

It's happened to me but only when the saw is hot and it still has fuel in the tank when you open it. Ive never had it happen after the saw ran out of gas.
