Hi, I started sharpening my own chain saw. However it is electric and the chain is almost impossible to advance by hand but it will go backwards easily. What can I do to get the chain out so I can sharpen on the machine thanks

I don’t use a machine, just a round file with a guide to sharpen. However, to your question… it seems like if the chain will turn one way easily, and hard the other, then you would just sharpen in the direction that it turns easily. Otherwise, take the chain off to sharpen – should just need to remove the bar nuts.

Cheers,
Brad

I can’t imagine why moving the chain backwards would hurt anything… unless the manual says something like “DO NOT TURN BACKWARDS” in big red letters :)

As for sharpening off the saw – depends on the sharpening system you have (and you did ask how to ‘get the chain out’ to sharpen).

Cheers,
Brad

get the chain out was a poor choice of words. What i want is to be able to move the chain along the bar without a tug of war. I am sharpening with a file

Chain lubed well? Just loosen the chain tensioner some and see if that helps. If not, as Brad said rotate it backwards.

As long as there is no grinding noise (as in a gear teeth not engaging properly) when you move the chain backwards it should be fine. It probably has at least one plastic gear so you don’t want to put any more wear on it than necessary. Just make sure that’s not why you can move it backwards more easily than forward. You should be able to see the motor turn inside the housing as it moves.

Some one correct me if I’m wrong. I would be reluctant to sharpen the chain while it is still on the bar for fear of getting fillings into the groove that the chain slides in. I can’t imagine that that would be a good thing.

Many folks sharpen the chain while it’s on the bar, professionals included, so I don’t think you need to worry about the filings.

I just sharpened a chain yesterday, after dulling it on Oak. I use an electric sharpener, this being the second one. Wore the first one out. Prior to that I used a file, but it was too slow if I had more than one chain. Even the $30 electric sharpener at Harbor Freight works good if used properly. That’s what I started with and finally wore out. Now I have a more expensive unit.

If a fellow has one chainsaw and rarely uses it, then sharpening by file is all he needs. That said, the HF sharpener is worth the $30.

Stihl makes jigs for sharpening chains on the bar. It’s the only way the jig will work. It’s ok to sharpen on the bar.

Brad and others, that “DO NOT TURN BACKWARDS” in big red letters :) might actually mean, Do not install the chain backwards. It looks like it could actually happen if the chain is stretched.

I don’t know for sure, but I seriously doubt an electric chain saw would have a plastic sprocket….... ......... Jerry (in Tucson)...... ......... Jerry (in Tucson)

That was the voice of experience Jerry. Here’s what happens when something goes wrong. Note how the teeth are basically gone. Not sure what made it do this exactly but the motor shaft had a metal gear and on the other side of this sprocket is what drives the chain. It appears to have some sort of glass or carbon fiber in it but it is definitely some sort of molded plastic.
