Hello. My name is Mark Blocker and in this segment we're going to cover hand filing chain saws. Hand filing chain saws is a method of using the hand file to sharpen a cutting teeth on a chain saw. First off you need to make sure you check with your owner's manual to make sure you've got the right sized file for the chain saw itself. If you have too large a file for the cut into its going to cut it in the wrong position and make it a dull. And if you have too small it cuts in too deeply and still doesn't set your cutting tooth correctly. So you have to have the right sized file for the chain saw. The next important thing we'll remember when filing a chain saw is that angle to into. You want to have the same angles to cut into. Most of the cutting teeth on the backside of it you'll see a diagonal line that's engraved or etched into the cutting tooth itself. That's the angle of the sharpening of what angle you want to sharpen with a file for that cutting tooth. Remember files only cut in one direction that's on a push stroke so you want to push through the chain itself, release tension as you draw back. 'Cause all you're going to do is pull down the cutting teeth on the file. And you want all your cutting teeth to be the same height. Once you select the tooth you'll have to rotate the chain through filing down each one at the same rate. So if you use three strokes to cut one tooth you want to use at least three or keep the stroke amounts the same on each cutting tooth so you keep them the same height. After you've rotated through and done all the cutting teeth in one direction we'll flip the chain saw over and start using the same procedure pushing through the cutting teeth counting how many times and move onto your next cutting tooth. And just continue that process until you've gone through. After you've sharpened all the cutting teeth there's also a raker or rider that fits right between the two teeth and what this is is a bar that adjusts how much of this cutting tooth is allowed to sink into the wood. As you grind away and sharpen the cutting teeth it becomes shorter and that distance lowers. So you have to take a few strokes off your rider or the rakers itself and file those down so they match the height to your cutting tooth. There's attachments and guides for how much the rakers and cutting teeth can be cut. Please check your owner's manual prior to hand sharpening your chain saw. So before you attempt to sharpen your chain saw check with the operator's manual or you can get the information on line from the manufacturer's on what size file to use and what the proper procedures are for sharpening the teeth and lowering the riders on the chain saw.
