My purpose for this purchase (Oregon 620-120) was to be able to sharpen my Oregon 18HX harvester chains for my firewood processor. The first issue is that the included instructions are of a horrible pic-to-graph variety in a non logical order requiring you to toggle back and forth in the booklet. The second issue I found is that the top of the chain tooth hits the underside of the mechanism that holds the backstop for tooth alignment each time I advance the chain. The final reason for disappointment and RETURN of the sharpener is that based on factory recommended settings from Oregon (Top Plate-35 degrees, Head Angle-55-60 degrees, Down Angle 10 degrees) are not achievable with this machine. When I set up as described, I am grinding the tie strap and am not getting sufficient depth-of-cut in the gullet of the tooth. I will be replacing this with a 520-120 as I believe the vise assembly will allow my settings to work correctly.
Two days later, after some suggested adjustment I thought I would give it one more try but alas the switch failed to work. We are down to 1 star now.

Good product for restoring your used chains back to factory specs. The instruction manual could be a little more clearer for a person who has never seen or used a machine of this nature.

I researched chain grinders for quite awhile before finally deciding to spend the extra money and buy this one . . . and I’m glad I did. After watching a few YouTube videos and visiting online discussion forums to make sure I learned how to sharpen chains correctly I went to work and began sharpening my chains. The chains I sharpened cut better than new chains and stay sharp just as long or longer. No more sharpening by hand and being frustrated while cutting for me. I highly recommend this grinder.

Not what I expected for a name brand product! Quality is average to low. I doubt it is made in the USA. First of all, there is no lock to keep the shaft from spinning when attaching the grinding wheel, they do not mention this in the manual. The motor is not reversible so you will have a burr on one side of the chain. Not a very professional grind. I did not send this product back, as I didn’t want to bother with a knock off model for less than half the price.

tres facile D’utilisation et éfficace.

Works great. The only problem is too many neighbours with dull chainsaws.
Tom Kaufmann –
Worked 100% better than I expected.
Sharpens more chains faster and more consistent than could ever do by hand.

Although I absolutely love this new grinder, I am going to mark it down one star for several reasons, and I hope Oregon is listening. First of all, I agree with many other reviewers that the manual is very close to being useless. I am quite familiar with chainsaws and sharpening, and I must confess I finally gave up on the manual, and just set it up from experience. Also, the handle supplied is very flimsy. When I pull the device down to make the cut, I can feel the handle bending. This is rediculous for a machine costing $400 dollars or more. The other items that earned it a markdown, are the plastic pieces on the paul adjustment and on the depth adjustment screws. Even if you tighten the plastic collars down, you can still easily turn the screws and knock the machine out of adjustment. On a positive note, it seems to do a very nice job of sharpening, and I love the hydraulic clamp. Overall, probably the best product out there for the home hobby guy, but not a professional tool by a long shot. Would I buy it again. Yes.

Have been sharpening chains for many years. (starting in 1968) Have used several different grinder units with many differing stones or diamond wheels. This unit does a great job with the chain. I like the accuracy of the grind after proper setup of each chain to be sharpened. I have been running a Stihl USG grinder for the last several years with great success, however the Stihl is a left handed grinder and the Oregon is right handed so I have some adjustments to make in how I do things.
Biggest complaint is visibility. The wheel safety guard covers so much of the wheel that visibility to what you are doing is severely limited. The low wattage integral light is pathetic at best as it is hidden completely inside the wheel guard. The light is too dim and the grid covering the bulb restricts most of what little light there is to get to the chain. The second light issue is that the light cannot be used for initial setup as it can only be turned on when the motor is spinning. I know of no one that makes the initial adjustments for a chain with the motor running – we all do it static to get to a close setup and only very minor adjustments are made with the wheel turning. The light needs a separate switch. Mine will soon along with a change from incandescent to LED bulb for a much higher lumen count while staying below the max wattage rating.
Overall this is a great chain grinder and will be serviceable for me for many years to come.

I purchased this 5-star product knowing that the instructions were marginal at best-hence the 4-star rating. CAVEAT: DO not use the numbers in the manual or video, USE THE SET-UP NUMBERS THAT COME WITH YOUR CHAIN!
I own all of the commercial saws, at least one of each, that Stihl makes so I am speaking from experience and understand the value of chain conservation since I buy chain by the spool.
In short, once the tool is set up I can run through a 36-inch full comp chain in 3 minutes due to the hydraulic clamp and produce out of the box results.
I would also suggest using a Timberline sharpener out in the field since this tool provides consistently repeatable results and is hands down the best in-between machine sharpening tools on the market. I hear many folks moaning about the price, but if you have this 620-120 electric tool, you should invest in a CNC machine tool with a carbide cutter that only enhances the machine profile, unlike a hand file that never cuts the same way twice.
Invest in CBN wheels and play frisbee with the useless pink wheels…
A little about the whining about plastic and parts I keep reading about:
1. The plastic pieces are ABS plastic – Football helmets, select chainsaw parts, car bumpers, Hard hats etc, are made from it.
2. Cheap handles, parts, and fitment issues are usually related to operator error and improper mounting methods.
3. Poor instructions – Oregon as well as many other youtube channels can get you through the process.
4. This machine is used in many commercial shops and operated by someone who has to bang out a lot of chains.
5. You did not buy the $1,200 version – Quit thinking that this machine is that version.
6. Due diligence on your part makes this machine perform like the $1,200 version
7. Rocks, nails, spikes, fence wire, etc damage your chain, this is where the economy of grinding must be embraced.
