Question about Oster 76974-160 Hair Trimmer

1 Answer

Loud buzzing noise

I shave my head w/ my Oster and at first the buzzing sound it produces is soft, however from time to time the buzzing sound will increase to such an extent that it will make me jump.  It will then stay at this volume from anywhere from 30 seconds to 5 minutes.  Shaking it or blowing excess hair from it doesn't seem to help.  Please help.

You will find a video for disassembly of the shaver at See link below

However, I seriously doubt that tightening anything is the problem. More that likely, the oscillator inside the swivel frame is cracked and causing the sound. You will probably need to replace the drive unit. See link below

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.

Shaver started making a much louder buzzing sound, no longer shaves as well and now hurts a bit to use. Can this be fixed?

Hello Robert, It sounds like the foil screen might have been damaged and is causing poor shaving performance. Typically, a screen will get small holes or tears in it after providing good service for some years, however, these very thin screen foils, can get damaged other ways too.

The best way to restore the best shaving performance is to replace both the foil screen AND the cutter head block (cutter head) as it could be possible that the cutter blades have become damaged or nicked and have caused the foil screen to become damaged, as a result.

I would contact and see if you can purchase a new set of the cutter block head and the screen foil for your particular Braun shaver model. As the Braun 360 is a tradename used on a couple of different model numbers, you really need the four (4) digit model number in order to locate the correct replacement parts.

Here's a link to their page with the various Braun replacement cutter blocks and foil screens. You might find your model number amoung them, otherwise, you can also give them a call at 1-888-476-1785 and ask them to assist you with selecting the proper replacement parts.

As you are no doubt aware, replacing the cutter head and foil screen is the best and simplest way to restore an electric shaver to a like new shaving condition and much less expensive than replacing the entire shaver.

I hope you find this Very Helpful and best regards!

The shaving blades came loose and fell off my sunbeam shaver, how do i put them back on?

Make sure the clippers are running.
Make sure the hinge (the bit you put the blade on) is open, if it is not, prize it open with a flat head screwdriver.
With the hinge open and facing you, slide the blade on the hinge with the blade number/size facing you. Snap the hinge shut.

Red L.E.D light won't stop flashing

Shaving head check indication After two years of use the red shaving unit symbol î will flash for 30 seconds during 7 shaves to indicate that you should check the condition of the shaving heads. This indication is based on an average shaving time of 3 minutes per shave. When the shaving head symbol flashes, all other symbols and lights are out. When the shaver is switched off, the shaving unit symbol disappears. When the red shaving unit symbol starts flashing, you should check the shaving heads for possible damage. If the shaving heads are damaged in any way, they must be replaced in order to obtain optimal shaving results
