STIHL HS 82 T/ Everything wrong (and right) Common problems.

Today we cover the HS 82T hedge trimmer and some of its faults. This will also cover the HS 82R as well as they are very similar. These are problems we see on a regular basis during hard commercial use. These hedge trimmers are outstanding units and when properly cared for will give you years of service.

[@joshuaheart2764]

These were questions I had. TY for explaining to someone who never owned a quality hedge trimmer. All my other equipment for the most part is STIHL. Best stuff that I've owned.

[@GoomNguyen]

My HS82T is definitely leaking fuel from the bottom of the Carburetor, but it still runs fine from cold. But after it’s hot for about an hour of use it seems to have fuel delivery issues and shuts off when I gas it.I then Will have to turn it off pump fuel manually to the carburetor via that clear pump thingy under the choke, and hold the throttle full blast to get it running again.

[@tgsgardenmaintenance4627]

Pardon the pun, but Stihl haven't needed to buy an 82, as my 81R Stihl runs perfectly after 10 years of commercial abuse!! ❤️ mine and never though anything could match it, however the Husqvarna 522HDR75X does just that, if not more! Would definitely recommend both!

[@ralphgowan58]

Great job explaining thank you.

Es normal que tire grasa por donde sale la cuchilla de la caja reductora????

[@kyleknight8267]

I have an HS 82 that has difficulty starting, It won't stay running after it starts, I usually start it by squeezing the primer bulb it 3-5 times, and setting the choke to full, then pull until it runs, usually about 2-3 pulls, then I depress the throttle for a while after it starts, but when I let go of the throttle it shuts off

[@b.n.4765]

Ever since I bought my hs82t it has always given me the same problem. Never took it in for servicing. Just used my other machines. The problem is when cutting vertically it will always start to rev really high. I will start with the tip down and when I start to rotate the trimmer to make the cut it just takes off. The few times I've needed to use it, it works okay and will do the job. It's just really annoying and takes more time to do the work.

[@blaablaahi]

Take it to a stihl tech. Sounds like a carb issue.

[@JC-dd5tj]

I just installed two fuel filters and problem resolved

[@Oli4vn]

Hi Wally, thanks for the informative video! One question I still have however, is what is the difference between the HS 81 and the HS 82? They look similar but there must be a reason for the model number to have been updated.

[@ollyjackson8733]

Great video. I've got the older model in this video. Not abused too bad, chainsaw through air filter casing which I've never repaired but still runs fine had it about 6 years I think now though. Trouble is I had a near full time jib last year where I used their electronic stihl and it was phenomenal. Using mine now it's SO loud I'm not sure if there's something wring with it like baffles have gone or something? Also when should I replace the blades? Stupidly i sharpened them with an angle grinder heavy handedly a few years ago so they just don't keep an edge now and there always seems to be slack between blades

[@joshny4766]

I bought an 82t late last summer. I was very impressed with it. It has been working fine this year until a few days ago when it started reving really high sporadically. Today when i was using them the problem got much worse and much more frequent. It didnt matter what angle i was holding them at. They idle fine, but when i hit the throttle even a little bit today, they surge/ rev very high until i let off. Any thoughts or solutions ? Still a carb issue?

[@wallysworkin823]

Sounds like a carb issue, if fuel is leaking around the air filter or exhaust you may need a carb overhaul or a new one.

[@toxicbilco4860]

I have the 82 and recently it hasn’t had full power and it’s sounds like full revs every 1-2 seconds is this a fuel problem

[@michaelmerrifield5914]

My HS82r has a leaky carby. You say that Stihl knows about it.... is it documented anywhere? I am planning on asking the dealer to replace the carby as you suggested, but they might deny there is a known issue. Thanks for the great video.

[@wallysworkin823]

The Stihl dealer should take care of it if it's still under warranty.

[@zarkum100]

Hello! Can you please make a video that shows how to get to the clutch? Mine revs up, but poor motion of the blades. Blades are fressh sharpened and move freely against each other. I guess a clutch problem... Thx in advance!

[@wallysworkin823]

The clutch drum may have broken, that is one thing I didn’t mention in the video, it’s rare. Let me see what I can do about a video.

[@mattchem6344]

Hi there, this is a great video thank you. On mine the engine revs, but the blades are not moving. What could this be? Many thanks, Matt

[@wallysworkin823]

Does it rev up normally or does it bog? If it revs up normally with no blade movement you could have a broken clutch drum.

[@user-jy9rn5yj7s]

My hedge cutter is over - accelerating every now and again, any ideas why this is?

[@wallysworkin823]

Could be a carburetor problem. They will lean out and rev up at angles. An adjustment may fix it, try turning the high side screw “H” counter clockwise a quarter turn.

[@thelandscapecompanyca]

Did adjusting the H screw solve your problem? Mines doing the same thing now

[@harleyhoracio1]

My HS 82t is going on its 3rd season (homeowner with 1/4 mile of 7’ tall hedge) I started experiencing lack of fuel delivery and the unit would die out. The fuel bulb was nearly empty. I removed the carb several times to see if anything was going on there. I replaced the fuel lines as well. Unit would run good for 30 or so minutes and start to die again. Broke out the unit for this season and got a couple hours out of it before it starved for fuel again. I noticed the vent was wet. Would this be causing my starving for fuel issue and if so why? Thanks in advance!

[@blakefox476]

try removing the gas cap next time it dies out. if it releases pressure your vent is the issue.

[@AeriaGamerz]

Where can I buy a tune up kit for these trimmer? Mine stopped working and need to know where to buy parts

[@wallysworkin823]

Go to Stihlusa (if you are in the US) and you can find a list of dealers near you. I recommend getting Stihl parts, we have been seeing some pretty poor aftermarket parts from Amazon and others.

[@gloooopo]

Got the newer model, 2 years aold and it's started pouring fuel out the exhaust pipe. Dodgy carb ??? Also difficult to start unless I hold the trigger same time as the pulling the starter rope

[@wallysworkin823]

Yes carburetor needs to be replaced. Check your warranty info, Stihl has beed good about replacing them as long as the unit is under warranty.

[@gloooopo]

@@wallysworkin823 Thanks for the reply. Now I can get it running again

[@gailsegal7769]

Hello, I can’t seem to find an answer anywhere, so I hope you can help. I have an 82R and while running it sounds like the motor is winding up. If there is a way for me to send you a video with sound that might help to understand what I am trying to explain. Hope to hear back from you . Tu Gail. (Gail’s Gardening)

My hedge cutter is hard to pull for starting

[@blakefox476]

If it hasn’t locked up, it probably will soon. You probably have a bearing going bad

[@raymondscholz4061]

HS 81T Runs find when level, cuts off when I roll over 90 degrees, one way its not as bad

[@wallysworkin823]

May need a carb replacement or overhaul but check the basics first, filters mainly.

Thank You!

[@oscarsalas3200]

Mine runs by itself when I start it without pushing the trigger what do you think it is. Thank You.

[@wallysworkin823]

What do you mean “runs by itself”? The blades are moving at idle?

[@oscarsalas3200]

@@wallysworkin823 yes full speed I allready adjusted the Throttle cable and it doesn't help

[@wallysworkin823]

@@oscarsalas3200 make sure the throttle is closing all the way, disconnect the cable from the carb if necessary. If it is make sure the plastic intake manifold is tight, they will loosen up. Also make sure your gaskets are good as well.

Hs82r owner here, best hedge cutter by far. Does the hard cut backs and the finer trims perfectly. I recommend the long bars 30". Never had an issue in 8 years of professional use

I've been working with outdoor power equipment nearly my whole life, and i recently started a property maintenance business in PA where I use hedge trimmers quite often. I've been getting by with the home depot special for the past season, and I'm planning on investing in the HS82R model. I really appreciate the attention to detail, the experience, and the knowledge that was put into making this review, and it was beyond helpful to me. It's becoming harder to find content that is geared towards people that understand how to maintenance and repair stuff like this, and I'm glad you're presenting the information in this manner. Very professional.

[@wallysworkin823]

Thanks for the kind words, I’m glad I can help people. Good luck with the maintenance business!

[@mc_scott]

Hello, great video. Whats the fix for the common leaking carburettor issue? Many thanks.

[@wallysworkin823]

Either a carb replacement or replacing the fuel pump diaphragm in the carb. There has been issues with the fuel pump gasket rubbing on the carb housing causing holes in the gasket. A complete overall kit may fix the issue.

[@rogernelson67]

I have a pretty serious fuel leak on mine. When you add gas, is that all the fuel lines or do I need a new tank?

[@wallysworkin823]

Check the fuel lines at the tank, they do split from age occasionally.

[@gmanstarr1439]

My blades move when I release the trigger still, not a speed, is there an issue with the carburettor.

[@wallysworkin823]

Sounds like you may have a clutch issue. Sometimes the pivot points on the clutch shoes will get sticky and cause the clutch to drag.
