5.0 out of 5 stars
works great!,
This review is from: Oregon 23820 Sure Sharp Chain Saw Manual Filing/Sharpening Guide (Lawn & Patio)
What a difference! I used this jig to sharpen the chain on my 18" Craftsman chain saw. Yesterday, it was burning its way through wood; today, it cuts like butter. This saw has never cut this well, even when the chain was factory fresh. I had even purchased a new Oregon chain, which also did not cut as well.
Easy to use - but be aware that you have to buy the correct round files for you chain, and also a flat file for filling the blade guides. This kit has the file handle, so you only need the files, which run about $7 for two. You just clamp it to the rivets of the chain and to the bar, set the depth, and then file. The only tricky part is setting the depth - just make sure you are not bottoming the file out below the cutter and you are golden. After filing a few cutters, you'll get the hang of it. Doesn't hurt to have a backup chain, however - first sharpen the one that cuts the worst, and by the time you get to your "good" chain, you will be an expert. I don't do a lot of cutting, and thought I could avoid the whole chain saw sharpening Zen, but you really have to learn it, as the blade goes dull after only an hour or so of cutting. So if you want to use a chain saw, you really do have to learn how to sharpen the chain yourself, or purchase several chains and find a good sharpening shop. If you have your chains shop-sharpened, however, you won't be able to touch them up in the field, due to differences in the sharpening grinders used in professional shops. Once you set the correct angles with this jig, you can touch up the chain easily by hand, using the same file. Don't file too much - it is easy to file away half of your cutter if you are not careful. Just a few strokes (3-5) will do it.

difficult to follow instructions,

Once I got it figured out it seems to work ok. The instructions are very difficult to follow and rely more on their terrible illustrations rather that using clear dialouge to explain. I had to have my brother figure it all out. Now that I understand it works pretty well.

Nonfunctional, inconsistent, poorly designed, and lousy instructions.,

I can't believe Oregon is marketing stuff like this POS! It seems like an engineer thought he/she had a good idea, let someone in China slap them together, and never pulled one out of the bubble wrap to test or use one before putting them on the shelves. I'm neither a novice nor mechanically challenged. I typically sharpen my chains on my electric grinder in the shop. I bought this hand unit last year in the off-season to have with my saw in the field in the event a chain needed a touch up. I thought I better check it out in the shop to avoid the learning curve in the field. Glad I did. It's now in the trash.Specifically: 1. The instructions are incomplete (good thing I had my trifocals). They fail to explain the function of one or more features (such as the slot-head screw operating one side of the spring loaded t-bars) and fail to address the means to achieve certain defined objectives (such as centering the chain for cutting, achieving and maintaining the center on chain rivets, or leveling the unit on the bar for proper angle and chain clearance). 2. After much fiddling with the unit, I managed to achieve what the instructions describe and worked through some of the issues not addressed. OK. Now I'm ready to sharpen. After the second tooth, the chain jumped above the t-bars and I had to start from scratch to reset and realign the unit. I tried repeatedly with different tensions on, and placement of, the T-bars and the unit. Once reset, the chain repeatedly "jumped" the alignment. I find the design flawed, particularly with how the unit is fixed to the bar and how the "t-bar" guides fail to hold their placement and that of the chain, making set-up frustrating and the unit useless. I also see no way for these issues to be remedied through adjustments or modification. My conclusion, for what it's worth, is that the unit is difficult to set up properly or consistently, will not maintain alignment, and won't retain the chain in any way acceptable. Maybe the garbage man can do better.
