Oster Golden A5 clippers not cutting

I have the Oster Golden A5 clippers. I was clipping my chow mix and the just stopped cutting. Blades are moving but the hair is not cutting. I used the Oster Wash and they started cutting for just a bit, then they stopped cutting again. I used the wash again but they did not start cutting this time. I took the nameplate off and brushed away any hair. Still not cutting. Any ideas?

    I have an Oster Golden A5 heavy duty animal clipper. I've removed the 2 screws which hold the name plate on to clean and oil it but when I put it all together again it only cuts for a few seconds then the blades are out of alignment. Every time I realign them they come back out of alignment. The problem is there are no diagrams with this model when you receive it! Can anyone help me please, I have a half done standard poodle and although they look ridiculous when cut believe me they look even worse "half cut" !

    A5 clippers. I was clipping and they just stopped cutting. Blades are moving but the hair is not cutting. I used the Oster oil and sometimes they cut for a few seconds again then stop again; this is very intermittant but they rarely cut for more than a minute or so. The clippers are fairly new and so too the blades. anyone have an idea of how I can remedy this?

    There seems to be a lot of people with cutting problems. A couple of things 1st you can not sharpen your own blades they are not flat ground they are hollow ground if they are flat they will not cut.
    2nd clippers will not cut through hair matts. The blade cannot feed into them. All Matt's must be combed out before you start. Poodle type hair is very bad for Matt's.

The stationary blades are held on by a couple of screws. Loosening these screws will allow some lateral movement of the blades. Adjust the blades till the proper alignment is restored. Just like scissors, there must be gaps between the moving and stationary blades at one point, then the moving blades close the gaps which cut the hair.

Here is how I fixed my problem with the A5: There is a curved piece of metal that is meant to push the moving blade down on the stationary blade (that is attached to the handle with the two show Phillips-head screws). It fits into a slot on the moving blade. There is also a very thin nylon cover that fits on to this metal piece that goes between the blade and this piece. It adds a slight extra thickness that causes the moving blade to press harder on to the stationary blade.
It came off unnoticed when I took off the blade and went underneath the curved piece. The blade goes back together without it and there was no indication that something was missing, other than the A5 did not cut.

When I took the tool apart again under a strong light, I saw that thin nylon cover hiding in there and worked out how to assemble the tool with it in place. It started working after that.

One other thing: in the meantime I also rubbed the two blade faces against a Japanese water-stone. Extremely mild grit (4000) but maybe this removed some unwanted residue. Perhaps this also helped in getting it going.

I'll buy a Oster A5 that the motor runs but does not clip

Posted on Nov 01, 2008

I ended up buying a new one speed clipper as the problem with the Oster A5 didn't resolve itself. The blades were not blunt by any means.

I did notice however, when I compared the two, that the old Oster A5 had a small piece of metal near to the blade which appeared to have sheared off?

The new blades are fine (so far!).

I have to say I'm not impressed with the standard and lack of service available for these things. They'are not exactly cheap!

I have used Oster clippers to trim my four sets of dogs over the past 42 years. I still have an Oster A5 and an Oster Golden A5.
I felt that these clippers were getting 'tired' so I purchased the Oster Turbo A5 thinking that it would really improve my trimming time on my two standard poodles. I have had problems from word go. After clipping 10 minutes, the clippers are burning my hand, let alone the poor dogs body. I lay the clippers down on a frozen ice pack in-between cutting and I use CoolLube and they just heat right back up again. Aside from throwing them into the Gulf, I hope someone has an answer on these Osters.

I have the Oster A5 Turbo clippers which I use clipping my horse. Unfortunately, each time I loan them to someone, they come back broken. Most times I have found it is the hard nylon gear. If anything "chinks" it, a gouge appears and the clipper won't cut. I now keep several of these on hand. However, my problem now is the blades. I have keep several sharpened at all times. However, I cannot seem to figure out how to put them back on. There is NO DIAGRAM on putting the blades back together on the clipper. I have about 5 pieces and after I assemble them in what I think is correct, the blades don't move. Help! Anyone know of a site for a diagram?

    I just found a site where you can find diagrams of the parts and insides of the clippers. You can order the parts, but for me, it helped me figure out how to put my blades back together. Go to It listed several different brands.

  • Paula Snow Sep 25, 2011

    the wires go toward the top of the clipper body then the two small pieces that fit together and the outer cover with the other blade. I figured it out all by my lonesome-and yep-I am a woman. I came back to help those before me, but I see you seem to have taken care of them quite well, clipncut. We are not all running on the same gears. Different talents for different minds. It seems simple-as some have stated. I certainly didn't expect to have to work it, baby. LOL

I have oster 6550 series a clippers, i installed new blades but they hardly clip any hair, when I loosen the tension the blades "move quicker" but vibrate with a loud noise

the tension should be pre set from the factory, if its more than one blade your having problems with then its likely there is a problem with the clippers.

My A5 clipper is not clipping at all.

If the blade mover is going when you turn the clipper on than all you need to do is take the blades apart and clean them well with a Oster spray and then oil them. I would recommend cool lube.

Newbie Clipper needing advice

This is from the Oster book:
Changing Blades
To Remove: IMPORTANT- stop motor; push latch with thumb while lifting blade away from clipper and slide off tongue.
To Replace: turn motor on; insert blade on tongue fully and then snap blade into place.

Note: if the hinge is flush against clipper, lift it up with a screwdriver.

From me - Never take your blades apart to clean them. You can slide them one side to the other to get the hair out. (One little hair, can stop them from cutting.) You need to buy a can of clipper blade cool from oster or andis both are good, and it really helps to lubricate the blade and keep them cool while clipping. If you live near a dog groomer, petsmart or something of the like. Ask them to show you how to remove the blade and I know they will be happy to show you. I tried to submit an image from the book, but I don't know if it will get here or not.

Oster Golden A5 keep turning themselves off whilst I'm clipping

Ok turn your clipper on and hold it still in one hand whilst with the other hold the cable near the end of the clipper and bend it, rotate and twist if your clipper cuts in and out you have a break in the cable which is tricky to fit but our web site Help section can help.
