My Oster A-5 motor runs normally, but when I engage the blades they do not function... ie. they do not go back and forth. I have used this clipper for several years and am familiar w/ its function. I do not think I am using it wrong. :-)

Re: Blades do not function
If the power lever (the tab that moves the blade back and forth) is not moving with the blade off, chances are that you have a stripped bakelite gear. Take the two screws out of the cover plate and remove it. Remove the lever. Remove the link (the metal part that the lever connects with). Remove the bakelite gear (the part that the link fits down over). You should then be able to see if the teeth are chewed or worn off to the point that the armature gear will not turn the bakelite gear. If that is the case, replace the gear. Amazon carries both single speed and 2 speed gears under Oster A5 clipper parts.

the clipper must be running when you try to fit a blade, if its all pf your blades your having trouble with then the problem is with your clippers, its possible the black latch which you need to depress to release a blade is bocken, loock at the end and make sure there is a hook which catches the blade, look at the picture.
Things You'll Need: Three-sided blade sharpener (coarse, medium, fine) Small flat head screwdriver step 1 Using the flat head screwdriver, unscrew the trimmer blades and remove them carefully. Wipe off any oil, grime or dirt that has built up on them as this may make it more difficult to handle and keep them in place during the manual portion of the sharpening process. Step 2 Separate the blades and re-apply only the moving blade to the tension spring. Then apply the moving blade to sharpener surface and turn the clippers or trimmers on. Hold the moving blade on the surface of the sharpener and apply light pressure while moving the blade back and forth for one to two minutes. You can also lay the blade on the sharpener first, then put the trimmer tension spring directly on the blade. Step 3 Turn off the clippers and remove the moving blade. It should look shiny and feel sharper. Step 4 Remove the guide from the guide blade by unscrewing it using the flat head screwdriver. Place the guide blade on the sharpening surface and manually run it back and forth for about one or two minutes or until it's been sharpened to your satisfaction. Screw the guide back onto the guide blade while being careful to readjust it before you tighten the screws. Step 5 Screw all the blades back on the trimmers and power them on to make sure they've been fitted correctly. Test them on your own hair to make sure they've been sharpened correctly and are set to the desired depth. Ads by Google Best Knife Sharpener Sharpen like the pros. Complete kit w/ 1x30 belt sander.

Depend on STIHL Electric Trimmers. www.STIHLdealers.com Tips & Warnings Which surface you choose, whether coarse, medium or fine, depends on how dull your blades are and how sharp you want to make them. If they are very dull, you will want to start with the coarse or medium side of the sharpener. If they just need a small amount of sharpening, use the fine side. If you've never sharpened electric trimmers before, you may want to visually observe and feel the sharpness of the blades with your fingers before you start to sharpen it. It may be hard to tell if the blades are sharp enough if you don't feel them just before you apply them to the sharpening surface.
There is a small gun-metal colored bar (dark gray or black) at the very rear, just below the back of the blade. It pushes inward, in the direction of the blade. Push it firmly in and pull up on the teeth of the blade. It should pop upward. You can then remove the blade from the tongue that it sits upon. When you want to put it back, slide the blade back on the tongue, then, WITH THE MOTOR TURNED ON, push the blade down to its seated position. It will click into place. Hope this helps you.
Assuming that you did not damage anything, the blades should go back on easily.
Slide the blade onto the hinged flat 'post'. Turn the clipper on. Fold closed the blade assembly into position against the clipper body.
If this does not ork, you must have damaged something.
Most likely, the blades were not adequately sharpened. To effectively sharpen these type blades, you need a special sharpening wheel designed for this task. If you have attempted to sharpen them on a sharpening stone or other device or you are not sufficiently knowledgeable in sharpening these blades, you probably have not satisfactorily sharpened them. Often, attempting to sharpen without the correct equipment makes them worse than when you started.

Hi A5 blades are not made to be unscrewed. They are snap on blades. You can call 800-830-3678 which is Oster Direct consumer service. They will walk you though the process or you can send them back to Oster and they will put them back together and realign them for you. Hope that helps.
