I'm kinda like that trimmer after 5-10 minutes when its really really hot I just quit, like I'm out of fuel.

 

Check the spark arrestor screen. If it is clogged take it out and leave it out.

My Echo has 2 air vents on both sides that sometimes clog up. Might be your problem. Can cause it to overheat.

 

Check the fuel lines for pinholes. I pulled my hair out over a stalling trimmer to find the cheap black fuel line had decomposed. If I have a problem with any echo the first thing I do is replace the black lines with the good clear yellow fuel line

 

you can clean the exhaust screen or leave it out like nosmo mentioned. I will be a little louder, but you'll usually get a little more power:weightlifter:

 

How old is it and is it 2 or 4 cycle and how much use does it get???

It 'could' be any # of things such as bad seals, bad coil pack, dirty carb etc...

 

Fuel cap vent is probably plugged. Next time it does this unscrew the cap some and then try to restart. What kind of trimmer?

 

Next time it happens check for spark. My fs100rx was doing about the same thing, turned out to be ignition coil.

 

bad coils very common to sthil. another reason to avoid them

Bingo!!!

Anyone ever checked how high their Husqvarna/Redmax trimmers operating temp reaches? I can't find any operating Temps posted for these trimmers?
Since any engine can run so lean it heats up to the point it melts a hole in the piston you'd think an operating range would be in the owners manual but I don't see it listed in my 525LST Husqvarnas manual? Mine dont act up like OP, never dies nor is it hard starting I just like to keep my engines around so if it runs cooler it will indeed last longer for sure. Brand new unit, more curiosity at this point?
Thanks all!

 

17 year old thread.......should start a new one......

 

I'll just ask this on a Husqvarna/RedMax site where more pros have the answer. More electric trimmer owners here now & those who clearly should be..lol.
Seens this OP got their help so these subjects no longer matter to others, Fluuu**** Hal so we can post same thing again on next page! Thanks anyway!

 

Don't cuss the farmer on a full stomach.
