Palax cutting problem

[rovers90]

I have a Palax KS35 Ergo and have a problem when cutting fairly large diameter hardwoods. Cutting oak at the moment and if it is over 8 inches in diameter, the chainsaw will cut about half way through and then the chain stops, as if its jamming. If released and then forced it may cut a bit more next time. It will, usually, eventually cut all the way through.

 

Any ideas what may be causing this?

 

I am running 325 chain - would a different size make any difference? The revs on the tractor (its a pto model) are usually set around 1300rpm.

The most likely thing is you are sharpening by hand and the chain is sharper one side than the other or the teeth are bigger one side. The bar is trying to cut a banana shape but cos its fixed in one plain cant. I avoid this by putting in a bench grinder after 6 hand sharpens. Check the bar is fixed at exactly 90 deg to the timber.

forgot to say try a brand new chain. Also we run on the 1000 pto with engine at 1100 rpm gives around 540 rpm using an adaptor. If you are on a 540 rpm pto the eng sounds too slow but check handbook .

was just gonna say any tractor should be reved at 1800 rpm if not more to get 540 pto speed... most processors i've come across though rev at 440rpm... still 1300 rpm wont be enough...give it bit more throttle and i'm sure that'l cure it...

Also check that the rails on the bar are not burred. Ime even the slightest burr can cause problems.

 

To eliminate bar and chain from problem fit new bar and new chain.

 

If problem persists check belt tensions, pulley condition, revs and bar alignment.

Thank you for the replies guys. The chain that was on when the problem was happening had just been professionally sharpened but I took it off and put a brand new chain on and its been working fine today.

 

Thanks everybody:thumbup:

You would be better off getting yourself a electric chain sharpene, it does not take long when you get used to them and you get all the cutters exactly the same length then. i use a oregon one which seems a good one.
