The blade driving lever is certainly supposed to move, if it isn't then take the cover off and check the cam gear, it's really easy to change it.

My oster 76 wont cut the hinge pops up everytime i turn it on i made sure the screws were on tight and still nothing Is there anything that needs to be replaced


If the hinge will pull up with your finger nails then it will need replacing. The hinge should be tight enough to hold the blade onto the clipper. Some models are fitted with a 'Latch' which should be pushed to release the blade if this is fitted and the release does not need to be pushed then a new latch needs to be fitted.

ok the blade latch only holds the blade into place.

the hinge assembly which the latch sits behind needs to be open, there is a silver piece with two ridges on, place a flat bladed screwdriver behind the hinge and this will lever open you can then slot the blade onto the hinge and close shut with the clipper running.

I don't know how or where to apply grease to my oster classic 76


The cover plate is the part with two screws that has the name and other info on it. If you remove the two screws and the plate, you will see a nylon part that moves the blade back and forth--that is the lever. The other end of the lever, with a hole in it, is connected to a metal part called the link. Both parts are easily removed by simply pulling them upward from the device. The bakelite gear is the part that the link sits on (the larger hole in the link). It too can be simply pulled up off the metal shaft that it rides upon (careful not to lose the washer under it). If you don’t have a tube of oster grease, a good white lithium grease is recommended in light application for the gear and the shafts (lever and gear shafts and armature gear and teeth of bakelite gear). Also, the bakelite gear shaft has a hole down its middle and two small holes that lead to the outside of the shaft. The shaft should be filled with grease so that grease can get through those small holes to lubicate the inside of the bakelite bearing. The small pads on each side of the lever (in the case) are oiled, not greased.
Oster clippers, by the way, are known for getting pretty warm. Oster blade wash will help with that, as well as oiling the blades.
Hope this helps you.

Bought Oster Golden A5 clippers new but did not


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.
Terms regarding these devices are all too often assumed as understood. For most purposes, these are what you have to know for the A5 Oster. The cover plate is the part with two screws that has the name and other info on it. If you remove the two screws and the plate, you will see a nylon part that moves the blade back and forth--that is the lever. The other end of the lever, with a hole in it, is connected to a metal part called the link. Both parts are easily removed by simply pulling them upward from the device. The bakelite gear is the part that the link sits on (the larger hole in the link). It too can be simply pulled up off the metal shaft that it rides upon (careful not to lose the washer under it). That gear is turned by the armature gear of the motor (which is where things get much too involved to cover here, but from that point on the device very rarely has problems). Incidentally, the lever, the link, and the gear can all quite simply be replaced. They are available quite inexpensively at Amazon under Oster A5 Clipper parts (note that the one speed and the two speed take different bakelite gears, but the lever and the link are the same). If you were to replace parts such as these or simply lubricate them, remember that a good white lithium grease is recommended in light application for the gear and the shafts (lever and gear shafts and armature gear). Also, the gear shaft has a hole down its middle (and two small holes that lead to the outside of the shaft. The shaft should be filled with grease so that grease can get through those small holes to lubicate the inside of the bakelite bearing. The two pads (one on each side of the lever) should be oiled. The simple way to tell if you need to replace parts is to grip the blade end of the lever while all parts are in place and try to move it back and forth, as though it were running the blade. If there is any more than the slightest movement, replace the lever (replace that anyway if the part that contacts the blade is rounded off) link and gear.
Good luck.

Run but will not cut


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.

Blade replacement


the lever on the clippers locates into the cutter of the clipper blade its only a matter of lining the lever up with the slot in the top blade which you can slide from side to side by hand. Please keep in mind wear on this plastic Drive Lever may lead to cutting problems.

This is for Clees534, with whom I have some sympathy. Terms regarding devices are all too often assumed as understood. For most purposes, these are what you have to know for the A5 Oster.

If you remove the two screws and the plate, you will see a nylon part that moves the blade back and forth--that is the lever.

Blade won't cut


Try replacing the Drive Lever which is located at the end of the clipper and goes from side to side, simply undo the two screws on the name plate/ gearbox cover and remove then pull the lever out. This is the most likely cause if you experiance the same problem with all blades.
