Replacing blades on Oster A5

Lever arm worn, blade blunt, or loss of movement inside the gearbox. It is possible to have a 'bad' sharpen.

It is common to that a Blade Sharpening Service return your blades just as blunt as before, or even worse.
I advise that you try a new Blade Sharpening Service; trying out only a couple blades to begin with.
I recommend a mobile/on-site sharpening service.

John! No Problem!
First put the bigger of the two blades witht the size/number facing down, put the cutter on top. (with the side with the flat side of the teeth facing down) Then put the tongue guide inside the tension spring, make sure the tension spring rail is on the tension rail and place them on top of the cutter.

This picture whows the front and back, it differs slightly from your blade, but its same meat different gravy!

Hold all this together with your finger and thumb, flip it over and scre the whole lot together!

have you had the blades sharpened by a professional company, you should be able to get around 25 cuts per blade if correctly sharpened. If you have what about the clippers try replacing the Lever which is located at the drive end and goes from side to side.

it seem the hinge on your clipper is worn out, here how you can check it, place blade on with the clipper off tap the blade forward if the blade pop,s open the hinge is worn out, you need to replace it, Now on the cutting part of the blade when was the last time you had your blade sharpen. if it been a while or you can not remember it's time to have it sharpen by a professional.

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.

There is a small gun-metal colored bar 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.

Are you sure you have Andis A5 or did you mean Oster A5 Clipper, if this clipper is A5 Clipper, You need to check the Lever for wear, The front of the Lever show wear on both side, Like white color and is not squad this Lever is worn. Need to replace. This Lever moves the blade side to side fully. if the Lever is worn the blade will not move fully side to side and the cutter blade the smaller blade will stay in the middle with hardly no travel to side to side and will not cut the hair even if you purchase new blades. Also I would like to mention if the Oster Locking Hinge is worn out and don't have the require tension to hold the blade in place the blade will not cut. How do you test the Oster Hinge on a Oster A5 Clipper,
(1) first close the hinge, in close potion with your finger nail try to open the Hinge, if the hinge slightly open or opens loose the Hinge is worn. if the Hinge is good it will not open or move and your nail may just brake your nail.
Many of my customers run into this type of problem, and the problem can be solve easily by checking these parts first.
One more item I would mention here if replace the A5 Hinge make sure you get the A5 Hinge not the Oster 76 Hinge they are driferrent, The A5 Hinge has on the back two wire's sticking out that fit on the Oster Latch for the A5 Hinge, the Oster 76 Hinge would not have these wire's on the back. I recommend replacing the Latch when you replace the Hinge. I hope this helps any body that have a A5 Oster clipper or A Oster 76 Clipper.

not usually we will not sharpen blades that are worn out as we cannot charge for something that does not cut!
make sure your blade is connecting with the drive of your clipper they might need an extra push depending if the blade has been adjusted.
