I have a Stihl FS91r that I typically use 45-60 minutes at a time when I trim my yard. Then maybe 3-4 times per year I find myself running it for 2-3 hours in a morning. On this long days, I find the bottom of my forearm near my elbow blisters from heat and rubbing on the top of the trimmers engine cover. The picture below is just something I found on the web, but depicts what I have a problem with. Any decent and economical solutions? I’m not coming up with much on my own. I have the same harness and loop handle shown in the picture. I don’t want the bicycle style handle.

It may not help a lot, but I always wear long sleeves (along with ear and eye protection as pictured) when I use my line trimmer. Mine is a larger T-handle version so the motor (hangs behind my back)...part of the reason I purchased the T-handle vs. 2 hands on the shaft version like yours.

Long sleeves are no fun on 90+ degree summer days, but help with flying debris.

Just a thought

This might solve your problem, I got one a few months ago and love it. Just make sure to loctite the screws

There are a bunch of forearm guards and forearm/elbow guards on the market, designed for various sports. Do you not want to wear something on your arm?

You're probably attached to your Stihl, but maybe replace it with something lighter, that you can one-hand a lot of the time. That was my personal solution. I'm now using the lightest curved Echo I could find. Haven't used the heavy straight shaft trimmer in years and I do 2,800 feet of pasture fence lines every 2 weeks.

Or, are you wanting some sort of insulated insulated shield to add to the engine cover, so your forearms will tan evenly?

A thread from a lawn care site about 20 years ago discussing various options:

Trimmer heats up my forearm!

When I operate my echo 2 cycle trimmer (left hand down) I get an incredible hot spot on my right forearm. You would think that the guys from echo would have figured this out by now and put the muffler on the other side? Am I missing something?

I really don’t know what I want, except my arm to not be blistered. I guess I was thinking there was something like insulation I could use on the trimmer so I wouldn’t have to wear something else in the heat.

Look up “welding sleeves” on Amazon.

I use a Stihl R90 frequently and don't have that issue, however I don't use the harness for that one. I do use a harness for the larger trimmer.

I've got to check but I think the engine position is turned on mine. In any case, I don't have a problem getting exhaust heat on my arm.

Edit- I just went and ran mine for a few minutes to check. My forearm is more to the left on the engine so the exhaust is a bit further away. I do remember that I changed the location of the ring to fit me, not sure if I changed anything else at the same time.

The link Clyde posted has a few folks mentioning using a “wrist band” slide up where contact with the trimmer is made. Almost like one of those tennis elbow sleeves I’ve seen before. That seems pretty simple and won’t be as bad as long sleeves or something like that. I need to find one of those.

Maybe you need a different length trimmer.

Maybe you need a different length trimmer.

Or a lawn service.

My wife has been pushing for me to hire one for many years. But, deep down, I think she really likes me being out of the house and watching me sweat while she sits on the screen porch sipping iced tea.

I have and use these arm protectors from Bailey's regularly.

I have FS110 , for the past 12 yrs I had handle bars , this summer removed them and went to the standard grip like yours. About 2 weeks ago , I was running mine and I didn't end up with blisters on the arm , but it did get hot. I do not use a strap to hold mine, maybe give some more movement or length to your strap. To help keep motor away from your body. When I got close the other day, I was on the creek bank , and working in a awkward position.
I noticed years ago when I used Harley FS55 or 65 curved shaft , I would burn my arm. I contacted Stihl, and a sales rep came to my house and he told me I needed to readjust the way I hold , and to shorten or length my reach, by adjusting the handle grip.
Sounds like both of us need to making some adjustments.

Do this

FSA 85 Lithium-Ion Straight-Shaft Professional Trimmer

The lithium-Ion battery powered STIHL FSA 85 straight-shaft professional grass trimmer is five times quieter than the STIHL gasoline-powered equivalent.

I did it 5-6 years ago and never regretted it

Kyle — just got an FSA 90R 2 weeks ago and really like it. Replaced FS 80 Pro. I don’t miss a 2-cycle trimmer.

Yea the variable speed trigger is the way to go. Love mine. Batteries are expensive but they last forevor. Got the leaf blower too. Things also a beast

I've got the same trimmer and run it about 40-50min when I use it - 4-5 times a year (Hate weed Wacking) and also have a similar problem with heat, however when it starts to get warm, I'll adjust so my forearm isn't on the motor or one arm it. I don't use the strap and about 30% of my "trimming" is the trimmer rotated 90° to edge mulch beds. I usually wear eyess, ears, boots, long pants and a light long sleeve shirt, regardless of temp cause it seems my body is a magnet for crap being thrown at me. (Likely user error... )

 

[MarkEagleUSA]

I always hold a trimmer across my body with the head to my left and engine to the right. That keeps my right arm well away from the heat.

My step dad used to blister his arm the same way. Mom found him some type of neoprene sleeve. Looks like an elbow brace or knee brace material but just covers his forearm. He hasn’t had a problem since. Think she picked it up at a sporting goods store.

 

[Technova]

there are heat sleeves for mechanics or race car guys to work on hot engines. I have one but don't know the brand.

The FIRST thing I'd try is to not use the harness! This will be you most economical and fastest option. If that doesn't work for you, then buy some type are arm shield. Bob
