I have a corded Wahl KM-1 (I think there is a KM-2 now). It is a heavy duty model, made for trimming horses, etc. It runs quiet and cool. I just drape the cord over a drawer pull and it stays out of my way. I've been using it for cutting my hair (what's left of it) for over 35 years.

Clippers arrived - I'll charge and try it out later.

It came with a small vial of oil. Manual indicates that I should keep the blades oiled (although I've never oiled the Peanut blades, just kept them clean).

Do I need to oil them or can I just keep them clean? If I need to oil them, can I use Slip 2000 (and some weight variant like EWL)? Or do I need to use this Wahl oil?

when you use oil, you'll hearing the blades speedup from the lubrication.

I keep a light coat on the blades after use since I store the clippers in a drawer in the bathroom where it gets really humid. A couple drops on the teeth while the clippers are running, then I dab my finger with a little bit and wipe the underside of the blade.

I did use Slip2000 EWL before when I ran out of the little bottle they give you. It's a bit thicker it seems, but don't think it matters too much.

I ended up buying one of the big bottles of the Wahl oil. $8 for 4 ounces will last me a long long time.

If you end up getting a bottle, some advice is to not remove the seal that is under the spout, but to just puncture the seal a couple times with a pin so you can better regulate a drop since it is very easy to dispense much more than you would want.

Thanks. Thx for the tip as well. Seems like regular Slip 2000 might be good - less viscous than EWL and synthetic. Would think that mineral oil and friction would become gummy over time. But I’ll stick to wahl oil for now.
