Leylandii - Chainsaw Blunting & Clogging With Swarf

It doesn't look the sort of trunk that would have any crap inside.  Have you checked the saw is oiling properly?

I'm glad you mentioned that - I've had my concerns in the past that it might not be, but I've only ever owned this one chainsaw so don't have an alternate reference. Recently, I removed the chain and bar and ran it to bleed / check the oiling mechanism and it certainly delivered oil. Whether sufficient, I can't say from my experience, but my instinct is that although it does go through oil (I have to top up the reservoir from time to time) it's at best very frugal.

Sometimes if the pump is on the way out the saw will pump oil out without a bar and chain on but when back together and in the wood they aren't oiling enough

Clean the bar groove out with a scraper if you have one, then test it again to check its oiling with the bar and chain on.  You can do this by running it full revs and pointing the nose of the bar onto a piece of wood.  You should see the oil spray onto the wood

Or the hole in the bar is blocked.

Sorry I posted at the same time as you posted the picture, thats not Leylandii, its some sort of pine. It looks pretty clean.

 

Leylandii is often multistemed, with tight unions that collect soil and grit.

Thanks Skyhuck. Apologies (to all) for the misinformation - I guess I've always thought of it as a Leylandii largely because it looked similar and I've viewed it as a 'nusciance tree', so it feel easily into that category. I've attached an image of an off-cut for identification, in case that's relevant.

Thuja maybe ?

[Zirynx]

From the responses I'm seeing (can't keep up with individuals, but thank you all!) I'm inferring a general consensus that there's insufficient oil delivery.

 

When I recently replaced the chain, I first stripped and gave everything a thorough clean and air dust - bar groove, bar holes, oil delivery hole and all cavities in and around the cover. Sounds like it just doesn't have the oil delivery 'oomph'!

Cypress of some sort

 

@Zirynx its probably a tree that the leylandii you know was cultivated from, similar but not quite leylandii

I can say with confidence that from even from brand new, this machine has *never ever* performed in a manner that would generate spray onto the wood from the end of the bar - the level of oil delivery has never been anywhere near that. Does indeed sound faulty or just sub-par.

what oil are you using?
