Remove the side cover to access the brake. Look for bent or broken components or maybe just sawdust is blocking the action. Good luck!

Husq 455 rancher chain saw. the chain locking spring in the cover is in the lock position and will not mount on the saw. how do i release the spring tension?

you should be able to release it with a flat screwdriver. you should see something that looks like a wheel where the chain brake locks to the brake handle when you put the cover back on. you should be able to twist that wheel and unlock it that way.

How to disengage or fix chain break on husqvarna 455 Rancher ?, cant get cover off to change blade. Pulling or pushing on the handle , no results .

It sounds as though you have tried resetting the brake to no avail. If I were you any Monday through Friday at 1300 - 1500 I would be in my local Husky dealer (not Lowes). Someone familiar with the saw that can see and touch it. I suspect you will need parts once the problem is isolated, order them there and the diagnosis will probably be gratis. Factor in the shipping and handling fee and most dealer prices are competitive.

If you have more questions or need additional help please reply below and I will get back to you. Good Luck. HTH

Cutting a log with 455 rancher chain locked up took cover off replaced chain ,chain spins with cover off put cover on chain is locked up again husqvarna

It sounds like the chain is too tight. Loosen up the tension on the chain by turning the tensioning screw located on the end of the saw where the bar goes out.

Cutting with 455 rancher chain locked up took cover off ,replaced chain and put cover on still locked up

Husqvarna - IPL, 455 Rancher/ 460, 2006-02, Chain Saw (example - may not be your saw):
http://weborder.husqvarna.com/order_static/doc/usa/2006/I06000/I0601076.pdf
See Detail A, pn 503 89 08-02. You can use a Crescent Wrench on one of the ears (left end) to reset it. With the cover positioned with pn 503 89 08-02 in the upper left rotate it CW until it nests, to reset it.

This works quite well:
Reset Chain Brake by Dolfoff
Please follow this link, http://www.fixya.com/support/t3102817-re_install_side_cover_after_chain
Cursor down to “Best Solution”, while there click the “Was this helpful? [Yes]” button
If you do not have a vise a large C clamp to a work surface might work, you may still need a block or two of wood.

You can download the IPL for you saw here:
HusqvarnaUSA.com
http://www.husqvarna.com/us/homeowner/support/download-manuals/
Enter the 3 digit model number (no XPs, Es, just the numbers)
Serial number decode – useful when downloading IPLs and Manuals
06 1500198
06 = year produced – 2006 (single digit before 2000)
15 = week produced - March
00198 = 198th unit Husky produced that week

I will wager you will NEVER again remove the cover with the brake set. Me either! Good Luck. HTH

What size file to sharpen chain for 55 rancher

It depends on the chain you have installed on the chainsaw. You can look at the numbers stamped on the drive link side of the cutting chain and it should have a 2 digit number that correlates to the size.

The factory chain supplied with the #455 rancher was a .325" pitch 3/8" chain.

Here's a link to the specs for your saw with some useful info
