Question about Makita 9820 - 2 Blade Sharpener
No . The blades are sharpened by grinding away the base of the wear until the edges between the teeth are sharp. It also necessary for the tension between the cutting blades is correct other wise the cutting teeth ride up over the hair and will not cut. Have a person who does sharpening of knives ,scissors and blades sharpen the clippers for you as the machine will get it right.

In order to sharpen these blades you must first dis-assemble them (paying particular attention to the way everything fits together), Next you need to get a piece of glass or something as flat as possible and tape a sheet of 180 grit emery paper with the rough side up. Then you put the upper blade on the emery paper wih the flat side down and stroke it back and forth in a straight line at least 100 strokes each way. Turn the blade over and examine the surface with a magnifying lens to see if you have honed the blade flat all the way across. Next turn the blade 90 degrees and again stroke the blade back and forth in a straight line. Turn the blade over and examine again to see if you have removed all the first series of strokes and the new set is flat from edge to edge. If so then put that blade aside and do the same thing to the lower blade until it is flat across and up and down. After reaching this stage you need to remove the 180 grit paper and go up to 230 grit paper and repeat the whole process. After completing the second stage you progress to 400 grit paper and repeat once again..
Make sure you keep the blades straight so the hone marks are up and down and from side to side and you should have an almost razor sharp cutting tool. Also DO NOT USE SAND PAPER only emery paper or cloth. I know this sounds like a lot of work but after you've done it a couple of times you can whip out a blade in about 20 minutes.

If your saw still has the original bar and chain, it was supplied with a .325" pitch chain and you'll need a 3/8" round file with a sharpening guide to properly sharpen it.
Here's a link to the Husqvarna site to the Rancher 455 models so you can select the correct manual to download, that matches your particular saw, based on the year of manufacture, etc.
There is some excellent information about maintaining your saw, along with a really good guide with step-by-step instructions for proper sharpening.
If you're having trouble figuring out the right manual for your saw, use the online Customer Support page and they'll reply.
Hope you find this Very Helpful - Best regards!

try getting they sharpened but this time when you use them oil between the two blades before during and after use. oil will maintain the useful life of blades.

It takes me about 5 minutes to Remove, Sharpen, and Re-install my chipper blade for my Bolens mc2500. First, If your using a screen or rollers in the discharge, then remove them. Look underneath, and you will see the thick flywheel. Make sure the spark pug wire is disconnected, then slowly turn the flywheel by hand until you see the two hex head bolts that hold the chipper blade to the flywheel. Also remember which way you take it off, so it goes back together the same way. using an open end or combination wrench remove the two hex bolts. Now to sharpen, I use a medium/ coarse honing tool made for lawnmower blades. I clamp the blade to the top edge of my Bolens with a pair of visegrips, then a little oil, and the sharpening tool, and I'm done sharpening in about 2 minutes, and then re-installing, reversing the removel process. I hope this helps.
