I got three Shindwaw 4 mix and had the guard off for two years. The only thing is the drive pads wear a lot faster. But I think yours is steel so that shouldn't be a problem.

They can only get so hot...it's air cooled. Don't listen to people who know nothing about engines.

Are you saying air cooled engines can't overheat?

No, but as long as the fins are clean and it's not running lean it will be fine.

Because air cooled engines definitely can overheat and be over worked. They can only move so much air over the fins and on a 100 degree day can overheat. I have personally done it.

Never "overheated" one in even 105 degree temps...whats ypu definition of overheated?

Was the engine detonating? Locked up?

The engine will start to loose power and rpm's. It takes a lot but I have done it a couple times trimming a hill side for 3-4 hours wide open. Let it cool down for 10 minutes and it's fine. It will seize if not allowed to cool or even scuff the exhaust port side of the piston.

i know its a risk when its 1 100 degress but i have a graveyard that takes 4 hrs to trim would this wear it out without a guard

No...it will be fine. No guard is like running the engine under a load...it just makes engine work harder.

In field experience in Texas with 3 months over 100F and some weeks over 110F and no failures. But these were not stihl and we all know they are homeowner product right?:laugh: Just kidding stihl is a fine product. Many of our units might go 30-40 minutes at a time on commericial. Take em off.

Oh, that must be that little thing we take off and throw away as soon as we pick up a new trimmer. :laugh:

I don't buy the overheating thing either...we use our stuff for miles of edging and trimming at a time, only shutting down to refill or change string and blades.

Have you tried using one of those edgers instead of trimmer on those long runs? I know the shortcomings in that you can end up walking half mile to get another tool to finish the job but was thinking it might be easier to use an edger? I tried one of the add on edgers and I thought I was going to have a muscle spasm.

I have 3 FS110 run no guard since they was new 3 yrs ago
But I run poly cut 40 heads fix string heads

If you run a bumper feed head then might want keep the guard on so dont over feed andwrap around ur leg
