Couple of Ms261-cm questions.

Did it mention that you can double your warranty if you bought Stihl XP oil at time of saw purchase?

 

[Patric Mudge]

No sadly not, that's a clause in the American Warranty policy I think. I remember something about buying 6 single 100ml shots of XP Ultra or 1L or something and it would double your warranty. That's actually why I bought a 1L tub of XP ULTRA when I bought the saw just in case. I've also changed the mix to 40-1 for future use and I'll see how the coking up goes. I'm sure it will be better though, all this Emissions stuff drives me nuts.

 

[RI Chevy]

Good. I think you will be fine.
Keep us up to date as to what and how your dealer handles these issues.

Just my tuppence worth on your oiler issue, you say tight on lubing the bar. We'll have you filled up the tank and oil tank, ran it till the fuel runs out and then looked how much is left in the oil tank ?
The reason I ask is, my 660 used less than 1/2 a tank (more like 1/3) of oil to a full tank of fuel. I knew there was a problem and could hardly see any oil comming of a 36" bar. It was the pump and it was set on full all the time.
All my other saws with ajustable Oilers, almost use a tank or about 3/4 or a bit more of a tank of oil per tank of fuel.

Some where I think it says how much it should lube, could be in the service manual.

Cheers

and it was the oiler on my 660, I checked everything and when I swapped it for an AM oiler. bingo it worked

 

[Patric Mudge]

from memory (I wasn't paying that much attention at the time) it used about 2/3 to 3/4 of a tank of oil with a tank of fuel. I will test it pending the result with the dealer on the cylinder. I cleaned it off this afternoon with the air compressor so its like it's unused. If they agree its an issue I am assuming they will swap the piston out. It would be nice just to have a new saw and start a fresh but I don't think that will happen!

 

[RI Chevy]

Just stand firm! Express your concerns. Hopefully you make out well! [emoji106]

 

[Patric Mudge]

I'm just trying to think of a reasonable excuse for removing the exhaust lol! Don't want them trying some get out "You shouldn't have done that" clause

 

[RI Chevy]

Nothing wrong with taking a muffler off to check the piston and cylinder out. Just a visual inspection.
Shouldn't void any warranty.
I take mufflers off my saws pretty regularly when using the saws a lot to keep an eye on things. Sort of an early warning check.

 

[Patric Mudge]

I can't imagine they would get funny, I've bought a few thousand worth of equipment from them and this is the first time I'm going back with a complaint. Ill post back tomorrow with an update, time to mull things over in the pub.

I was reading and looking for oil output, I can't remember where I saw it before, although. I do remember oiler piston stroke and somthing else to do with the 660 Oilers and the ozzy prefered oiler

I know with the High output that stihl sell they say to watch the oil don't run dry.
Others try to use and have used another oiler from the next bigger cc size saw. But not all fit.

I guess if you do some sums IE fuel tank vol and oil tank vol. you will get a rough ratio. I would think it would be simular on differnt models and change a bit with max lenght of bar for saw, IE, cc of saw and max bar.
but I know ozzzy hard woods are an exception hence the oiler for the 660.

I also read that others said new oilers are tight but stihls literature says it uses less oil. So my guess is they may ask how much oil does it use on a tank full fuel with constant use.

 

[RI Chevy]

Just mentioning, but I also think Stihl chains pick up oil from the bar grooves a bit better than other chains. Could be that the oil is on the chain links, rather than staying in the bar grooves?

 

[Wonkydonkey]

Well I found the oil pump rates, it is in the sevice manual, so maybe @ray benson can send me and you @Patric Mudge a copy of the 261 as I can't find it and the only few I have, is the 260 and I looked at the 251.
These are the figures

Edit I've attached the 260 oil rates and you can see the difference with a ajustable oiler
Cheers

 

[Patric Mudge]

Thanks @Wonkydonkey I have a copy of the 261 manual which I used for reference when removing the exhaust (I wanted torque specs for the assembly but "tight" is stated in the manual lol. 9.4Nm was the answer) I'll PM a copy of the manual. I think the chain is oiling fine as it is always wet and never seems to get hot. I'm just used to the old oil blasting smokers that can leave a 1ft high streak of oil on a tree with an 18 bar. I've seen people run 25 bars on a 260 and that's what I wanted to do with this as its mostly for limbing, being 6'2 it puts my back out being bent over all day. I just like to have some "room" left in a machine so its not always pushed to the max limit on everything.

Your gonna want to mod the oiler to run a 25.

Cheers Ray,,,

And concretegrazer..
Being taller than a giraffe, 6'4" without my high heals on. Which I love to wear while liming with the guys. I got a bent back hence my name, wonky, not sure if I should talk about the donkey bit

I don't think I'm gonna use a 25" bar to limb, although I did use a 3/8 chain with a 25" bar to cut a hedge once (the clutch took some time to ingauge, the chain dragged), the hedge was 2' wide and the stems were to big for the hs 45, so as a simple solution and a weight thing I slapped it down the easiest way

 

[Patric Mudge]

Update time, I took it into the dealer today and they took a look. The scratch is only on the skirt and not the rings as I previously thought. They logged the issue with stihl using the serial number and told me to run it and if something goes wrong then they will sort it out then. I've probably made about 100 cuts with it today and the oiler seems to be better judging by the mist of oil in front of the logging stand I was using. My next issue is a weird noise from the recoil starter that sounds like its catching and making a clockwork type noise whilst its running but I think that it was always like that and I am just being pedantic and having one of those "hearing noises" sessions like when I turn the radio off in the car

 

[RI Chevy]

Good. They documented the issues. Did they do anything for the oiler? Did they look at the crust atop the piston?

 

[Mastermind]

I tore down a new 395xp a couple of weeks ago and found a place on the intake skirt about like the one in the OP.

And.....it's one of many I've found over the years.

Just a reminder that no manufacturer is immune to assembly flaws.
