Question:
I just acquired a 455e rancher. It’s preowned but has been used very little. It runs great and cuts like crazy. While I’m cutting the chain stops abruptly. The bar gets clogged with sawdust and binds up. What could be the problem?
Answer
Chris,
Is the bar getting very hot when it abruptly stops, Is the chain tensioned properly ? or is it also getting very tight when it abruptly stops? As soon as it stops with a glove on your hand, and the saw off and shutdown, are you able to pull on the chain, and does it move freely or does it feel like something is jamming the chain? Is your chain brake operating correctly or is it partially engaged, again engage and disengage the chain brake, and then pull on the chain, the chain should move very freely when disengaged, and should not move at all when its engaged. If this is not the case then I would recommend you take the chainsaw to an Authorized Husqvarna repair center, and have you brake band adjusted.
Oh, I'm also assuming that you are keeping the brake band inside the clutch cover clean. You also stated your saw is getting clogged with sawdust, you also may want to check that your chain is sharpened properly, you should be making lots of wood chips, and Not lots of sawdust.
Just a thought, and I hope this helps.

When It jams I take the chain off. I have to pry the chain out the bar groove because it is cloged with chips. It appears that the cluch and break are working properly. Some one told me the chain isn't getting oiled enough from the chain oiler. I've never have had this problem with a chain saw before.

Chris, Thanks for the immediate reply. Yes having oil is important but from your description of having to pry the chain out of the bar, I don't believe this to be an oil problem, I would really suspect that your wood chips are too fine almost like sawdust, and that the chain is not cleaning out the bar.
Your chain has several different links, with different purposes, obviously you have right and left cutters, and in front of the cutter link is a raker link or depth gauge which allows you to control the depth of the chip and size of the wood chip, your rakers may need to be filed down a little to make your chips bigger, make sure you use a depth gauge to do this. Also on the drive links below the rakers which fit into the bar, to keep the chain on the bar, the drive links should have a distinct curve and a little notch that goes into the bar groove. It sounds like your drive links are not cleaning out the bar groove, this is also a sharpening or chain problem that is often overlooked when sharpening, some chainsaw users only sharpen the cutters. So Just some things to think about, I would be very curious I f you tried a brand new sharp chain, If you still would have the problem?
If you would like more Information about the different links on the chain, a great site is "Oregonchain.com", they have several tutorials and information about the links that I discussed, "Left and right cutters links", "rakers or depth links", and "drive links". Anyhow, I would definitely make sure your oiler is working but you may find a brand new chain fixes the problem, and If it does don't throw the old chain away, just take some time with it If you sharpen it yourself, and check the rakers and drive links to see If they need to be re-shaped, or you may need to take the chain to a good service shop that knows how make these chain adjustments.
Again hope this helps, and good luck.
