[How does Dewalt 8" bench top grinder get cooled when in use]

I am curious as to how does my Dewalt 8" Bench top Grinder get cooling air when in use, since I see no vent opening in the body and I find it gets very warm after 15-20 minutes of use, with light grinding and wire-brushing; is this normal?

 

Thanks.

[Replacement capacitor for elec. motor]

Hello, I am looking for advice on replacing a capacitor for my 1/3 HP 2.8 Amp induction motor (bench-top grinder). I do not have the original capacitor that came with the motor, and need a replacement. What size capacitor should I purchase.

 

Thanks,

Michael.
