Fix for 480 CFM Blower( trigger safety)

  • Not a Problem
People often or have talked how they wish the trigger didn't have a safety.. After all, what could be the worst scenario... You blow someone accidentally?

I've done this with the bail for my old mower.... A strip of good velcro you can buy at the home depot cut and wrapped around the trigger release.

This way it holds it so you don't have to! It really stays put.

On the 480 cfm blower, ok, I see your point, though the safety never really crossed my mind. But on a lawn mower? Dude, you're living dangerously!

Dangerously, I think not...

I used it on the gas lawn mower when I needed the engine to run when doing some repairs, when warming it up a little before an oil change so the oil would drain better, when wanting to run the fuel lines dry for long term storage, etc.

So no I never used the velcro when mowing the grass.

On, so you held it down so you would not be wearing out your hands?

Also, for the 480CFM blower, you could just take it apart and remove the safety lever entirely.

I sat across from the corporate safety manager at a company during an internship—he spent all day every day reviewing what led up to serious accidents. There was almost always a safety mechanism that had been overridden.

Do all safety overrides lead to injury or death? No. But if you get seriously hurt then there's a good chance you bypassed something that would have kept you from getting hurt.

Hindsight is 20-20... unless you lose an eye.

Removing it would be a hassle. But on your prior comment...

It wasn't to keep me from wearing out my hands, it was because I couldn't work on the mower with my hands while my hands were up on the end of the handle.

I've learned to be fairly efficient and think outside of the box when working on mechanical Things.. In my past I've been a driveability technician at a dealership, a mechanic at Sears Automotive Center, support on servers, workstations, networks at a large datacenter.

Technicians have to disable things all the time when working under the hood.

Sometimes I'd be driving around with the foreman while one of us at our bodies hanging out the side door trying to locate squeaks and rattles are new cars under warranties.

How about driving down the road with the engine Hood unlatched because you had hoses hanging out of it for test equipment?

The list goes on and on.

This is weird, a mechanic being advised on how to fix an engine. Really?

All I did was give a good idea on how to work around something that Ego has subsequently removed from their blowers. And complained about my other customers and professional reviewers online. Geez.

hm. I've done a lot of work on the EGO and Kobalt blowers, I've taken both of them apart before, I've adjusted the harmonics of the Kobalt, I tried while lacking the proper parts to add a second fan to the EGO (without success), I've done a lot of work on these blowers. Because the Kobalt is so much easier to take apart, I'm going to put a Scorpion 1770W motor into the Kobalt and modify its circuitry to accommodate it. It will go from a blower rated at 750W to rated at over twice that with a 2 second turbo boost of 2200W.  That might make it blow 200mph instead of the normal 140 with its blower tube. The only reason I don't do that with EGO blowers is because they have higher tolerances and are extremely difficult to disassemble.

KR, apologies, I read your initial post as using Velcro to defeat the bail switch on your mower while actually mowing. I didn't realize you were doing so just to facilitate repairs and maintenance.

David I suppose you should add a safety switch to your 530 CFM Blower ( if you have one). Doesn't it run even faster and more Dangerously? After all, you wouldn't want to lose and eye.. as you said.

Obviously Ego does not consider it a safety issue. But yes people should not mess with safety features in general.

Hey Kid Rock, my comments are directed more toward others who may be reading that at you. It's easy to get in over your head without realizing it when you start bypassing things—that's all.

Reading about or seeing things on the internet makes us all think we know more than we really do, just enough to be dangerous.

We ain't advising you on how to fix an engine. Then again, we also are not actually seeing with our own eyes what you're actually doing.  Blue and I just notice something along the lines of "disabled safety on a lawn mower" and got concerned. We haven't said jack squat about how you should do your job. I'm pretty sure I said "as long as you know what you're doing", and you apparently do.  I've just been stating facts.

Oh come on... I was trying my best not to be drawn into another 100 page thread.  rofl.

About the 480 safety trigger?  I love my 530.  Does that answer it?

Atom, you had to say edger.  I was using my string trimmer to completely destroy the edges of my lawn yesterday  :-(.  I'm not buying an edger because my gut feeling is that by this time next year I will be plugging my 7.5AH battery into that bad boy.

Yeah, I'd bet a hundred bucks that EGO's gonna come out with one next year... and a pole saw.  And maybe a brush cutter later, maybe 2018. And maybe a riding mower in 2019. And maybe a car in 2033.

What makes you think that you won't have a 20Ah backpack battery by then? or a 9Ah battery that looks just like your 7.5Ah? by the time you get that edger at this time next year?

You are killing me Atom... My wallet is going to disintegrate.  BTW, I'm trying to take more of a back seat to a lot of these threads, because it seems that once the point is made and EGO responds, there isn't a need to put fuel on the fire. 

Guess I'm just looking to be more helpful than argumentative.  I enjoy your posts.

Speaking of battery packs.  I don't know how much bigger they can get before the size causes a problem.  I'm thinking the 7.5AH battery is sort of the sweet spot.

I think Ego has a prototype for a backpack battery that is more than 20Ah—it's not announced for the US yet and I'm not sure if it's actually in production for any markets yet. But marketing photos exist if you dig around.

Edger, pole saw... almost like Ego just needs to come out with a power head with interchangeable tools!

Pretty soon 3Ah cells are going to be mass produceable, so a 9Ah pack will be the same size as a 7.5Ah pack. Plus I think Jennifer is watching this, and what worries me is that when she responds, this thread will be closed :-(.

Hey David, I hear that Greenworks did that with their string trimmer, that it can be converted into a bladed edger. I don't know if that is true or not, but EGO should definitely do something like that, and I know that I'm not the first person to suggest that.

9 Ah? I'm pretty sure they could do that anything. Right now it looks like they are using 2.5 Ah cells (2.5, 5.0 and 7.5 Ah batteries).

Check what cells are on the market... If they switched to the 3 or 5 Ah cells... Wow!

2.5 Ah battery becomes 5 Ah.
7.5 Ah battery becomes 15 Ah! And the same size cases!

Oh this is my thread... Oops. I don't know about high drain or low drain cells. I didn't really think of the existence of one vs. The other. But I do know different chemistries have different abilities for high drain. I assume that's what you meant by the acronyms that you gave.

Are you saying that the cells in the current ego batteries are some kind of special high drain cells compared to most of the 18650 s out there?

High drain 3Ah 18650 cells are already in production. Bosch has announced a 6Ah 18v Lithium pack that uses ten of them. Milwaukee has also announced an 18v 9Ah pack that uses 15 of them.

You need to keep in mind also, the more parallel strings of cells you have in a pack the less load per cell there is for a given pack output. For example, the 7.5Ah pack uses three strings of 14 cells in parallel (14s3p) so for an 18 Amp load each string of cells (each cell actually) will see 1/3 of that, or 6A. To produce that same amount of output, the 2.5Ah pack would draw the full 18A from each cell as it only has one string of 14 cells (14s1p).

Therefore it is less critical to have higher drain cells in larger packs with multiple strings.

Now in the case of increasing the capacity of an existing pack design, like going from the 4Ah to the 5Ah Ego pack, the cell arrangement doesn't change. In this case, the 2.5Ah cells in the 5Ah pack need to have similar discharge characteristics compared to the 2Ah cells in the 4Ah pack if performance is to stay the same.

This is the case with 18v power tool batteries... fixed form, increased cell capacity.

I know, that's why I suggested a future 9Ah pack that looks just like a 7.5Ah pack.

That is also why I designed a backpack battery that actually uses ICRs, 10 strings.

Yeah, I have to agree (as I usually do) with Blue on this one, as long as you know what you're doing. EGO isn't liable for injuries caused as a result of safety features disabled by you :), but I assume you know that because that's just common sense.

I've just seen it mentioned in reviews too. But for me, I think I'm going to grow to like not having it.

Even Ego removed it on the 530 CFM Blower...

Recommendations from customers, reviewers and seeing the light I assume!

It worked. I get into things like battery tech, light bulb technology, motor tech and it always feels good to read up or talk about cool lighting design...

4 lighting layers :

¬ Focal
¬ Task
¬ Decorative
¬ ambient

Well, you and I should have a blast. I've designed laser diodes that have adjustable wavelength before, I decorate my room with Christmas lights and am extremely particular about the reds, blues, and greens, I'll use the sun to fade the colors to very specific shades, I mess with motors pretty frequently... yep, it is definitely stuff I mess with.

Lasers, now that's something that has always interested me. I did concert light shows and designed club lasers, many years ago. It was a pain back then
