Oster Golden A5 2-Speed Universal Motor Clipper 78005-140 - Answered Questions & Fixed issues

I bought an Oster Golden A5 new in a pet store in 2000. It did not work reliably out of the box- needed constant tweaking of the blade tension screws. It sat on a shelf for 15 years while I paid for many grooming sessions. Over the years I would try to get it to work; in 2015, I bought a generic brand #5 blade from a beauty supply, and it refuses to cut no matter what I do. Today, I spent 40 bucks on an Andis #10 and low and behold it cuts like a dream. Went back to the store and bought a #5 FC and it also cuts like a dream. So all my troubles were caused by 2 blades that were defective right out of the box...

Looks like you are in the poo then because nobody will be able to help you without knowing exactly what model you are talking about.

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.

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.

I take it you mean the plastic srews? these are plastic caps behind which are the carbon brushes.

Many people send clippers to www.angliaclipperservices.com most parts are in stock for Oster, Andis, Aesculap, Moser/Wahl, and horse clippers, the turnaround is only a week.

are you applying enough oil in the right places? clipper oiling

Its possible the gear wheel which is located under the name plate has slipped, if you remove the plate, lever and drive link the gear will pull off.
Inspect the teeth on the gear if there are signs of damage or slipping this is likely to be the problem.

See if the hair is clogging somewhere, do you have user guide? Try clippers for dogs or go to the groomers.

Good Luck

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.

blue wire to the switch and brown to the brass connection.

ok rush can be removed with wire wool or a wire brush and will be prevented by the application of oil.
Grease should be inserted into the gearbox which is located under the name plate, for clipper oil have a look at the page.
