TBH im not sure but you are probably correct. Maybe a worn clutch and a previously replaced drum. I will check out the clutch before I reassemble the saw but IIRC it didn't look badly worn but I may have over looked it. There was a lot of grumbling, huffing and cursing going on at the time.

Plenty of good advice above. I would replace the fuel lines and jubilee clips and go from there as it sounds like the fuel is running back into the tank over time. If that doesn't work then its diesel pump recon time IMO.

A customer brought a bit of a battered 291 in a couple of weeks ago with an issue. I had a chance to look at it this week, I think he's had his moneys worth out of the clutch drum to say the least. It was a bit of a job to get he drum off as it had ripped to bits and was well and truly jammed up in the cashing and the brake band. This was the state of it. The big problem was getting the clutch off, the drum had taken the end of the worm wheel spring so tit had to come off. I usually just use an impact wrench to whizz clutches off but his time it was having none of it. I tried penetrating fluid which didn't help then tried the old piston stop and big socket bar and that didn't move it so I tried a windy gun and still nothing! The only options I thought about where to cut it off with a grinder or give it some heat. These machines are just made of plastic, plastic pump, plastic casing etc. I gave the heat a go to save the clutch but not loads of heat and it actually worked, usually you have to heat stuff up to cherry red to get them to move but I think the oil from the day before may have helped. I still had to wind the air gun up but it did pop off first spin. Not got it back together yet as we didn't have the worm wheel in stock but it should be up and running next week. If I come accross this issue again I think I will tap one of the mechanics up in the next unit for their snap on wrench.

You need to check if its damaged. Its a bit of a complicated setup but IIRC you need to follow the wiring from the motor back to where it goes into the tube. From the tube it curls around the articled part and its the bit after that where the issue is.

The issues I've seen with the battery hedge trimmers is with the wiring loom where it moves from the pole to the head. It runs too close to moving parts and isn't shielded. It could be that if its got wet and shorted out as the other components should stand up to a bit of water.

Probably did! £20 labour soon disappears once you take the machine in, tag it up write out the quote and phone the customer, usually several times, never mind repairing the thing. Hopefully it will help someone in the future if they come accross the same issue and this thread.

If you block the fuel inlet to the carb, just put your thumb over it and create a vacuum on the primer side, put some fuel pipe on it and suck you should not be able to draw air through, if you can you either have a hole in the pump gasket or usually a bad check valve.

As Stubby said it was user error rather than a manufacturing issue. The 395XP is a really good saw. I have a brand new one knocking about that has a cracked crankcase, I should really sell it on or fix it up. It will be the last of the 395's.

I was only joking. I charged £20, he's a good customer and I learned something.

The long winded version. Slackened off the chain so its hanging a lot and after a bit of messing about I could see that the chain was getting pinched at the top of the guide bar. I turned the bar and it did the same thing, the sprocket cover and guide plate (this thing in case people are wondering what it is Husqvarna 522 74 28-01 Chain Guide Plate SKYLANDEQUIPMENT.COM Replacement chain guide plate for the Husqvarna chainsaws listed below. FITS HUSQVARNA CHAINSAW MODELS 545 MARK II, 545G MARK II, 550 XP MARK II, 550 XPG MARK II... In this photo you can see the cover was scored along the top probably due to a thrown chain. ) Although the surface didn't feel raised I gave it a bit of a tickle with the angle grinder and boom, job done. The amount of material that I removed was next to nothing but enough to cause an issue that I haven't came across before. BTW Im not going to tell the customer that I repaired the cover I'm going to just bang a new one on for the handsome sum of £92 quid. I hope he doesn't use Arbtalk!

Sorted the problem today. To cut to the chase the sprocket cover was damaged which was causing the bar to pinch the chain. I will go into some boring detail later when I have a bit of time.

It is a bit strange that some saws melt the cover quicker than others. I only mentioned the running it on the deck as it can effect top handles as the exhaust is usually pointing downwards so the the gases can bounce off the floor back towards the cover. Maybe some heat reflective tape will help.

That and also a different ignition coil IIRC. All of the current cs2511's will be an x series going back maybe 4-5 ish years.

Had any luck sorting out the issue?

From what I've heard recently its looking like December 2025/Jan 2026

Do you leave it running while its sitting on the floor?

Not had a chance yet as there are quite a few machines in the workshop. I will hopefully get a bit of time in there this week to check it out.

Good shout out. Its worth checking out the PDF on the gov web site as some machines have already been checked. If your serial number falls within the range of affected machines but has a black dot next to the serial number then it has already been inspected and is fit for use. If you are unsure then speak to your local Stihl dealer.

I'm thinking that it might be something like that causing the problem. Its metal. I have a few old ones knocking about from knackered 550/560s so I will swap it out.

Looking at the vids and pics It looks like the zigzag bit is way chunkier than a Petzl zigzag.

This is the part number for the wrap handle kit 593202803, you get the handle plus some screws and an AV. Its not something that we stock and I cant see any in the UK selling it but ls engineers might be able to help you out. If you get stuck then send us an email as we can order it in for you, will prob be a week or two.

Thanks Pete, Ill check it out. I suggested that he keeps the bar and chain and replace everything else, he didn't seem too keen on that option

Had a customer drop in yesterday with a 562XP. Basically as soon as you tighten the bar nuts the chain gets really tight, slacken the nuts of a tiny bit to get the tension right and the chain moves around the bar by hand nicely, tighten the nuts down and it hardly turns. I only had a quick look at it, bar and chain are matching, it had the same issue with his old bar and chain, nothing seems to be out of place in regards to the chain getting pinched, the drum isn't contacting the sprocket cover although the clutch springs are really slack but they didn't cause tick over issues which I thought strange, and there didn't seem to be too much movement in the clutch bearing and the guide plate looked OK. I will have a proper look over it next week starting by swapping out the sprocket cover to rule out any issue with that. Im thinking that somehow the bar is somehow twisting causing the issue. He also said that he seems to be replacing the rim sprocket more often than usual, the rim floats freely on the drum. Has anyone came across this issue before?

It's made in the UK, that's about the extent of my knowledge tbh as my climbing days are well over. I only ever used prussik loops then swapped to a hitch climber and then the zigzag which I thought was a game changer. It will be interesting to see how well it works with SRT and how differently it works either on its own or used with a tether. I don't get the removal swivel bit as I thought that it could be used with or without the swivel but it doesn't look like it can't. Has anyone had any hands on experience with it?
