PC getting HOT!

I just bought this PC on ebay, hoping to save a few dollars; however, on any of the lower settings, it gets bogged down, and gets really hot. I mean really hot.

Should this be happening?
 
Probably not, mine will get warm, but never hot even after 2 hours a use. I'd look into exchanging it at the place you got it at.
 
I think it might be a fucntion of d/as' in general. On my makita, intructios recommend against using at low speeds for too long a time, or parts failure could occur.
 
Is it a brand new one, refurbished, or used? If it is brand new and a repitable seller I would call them. Refurb. does it have a warranty? Used probabley out of luck. I have run mine for several hours at lower speed and it gets warm, but not hot. At lower speeds are you pressing down or letting the weight of the machine do the work? Bearing down on it will make it get warm much quicker.
 
thanks guys. i was just resting my hand on top and that was bogging it down. I'm gonna contact the guy that I bought it from. He was pretty a pretty reputable seller on ebay... but i guess since i paid 70 for it instead of 120, I can't complain too much. It functions fine at speeds of 5 or higher... I might just have to deal with it getting hot.

Thanks again

If it is used check the brushes. See if they are worn down alot. I'm going from memory so don't qoute me on this. Check on the side of the buffer there should be two large screw. They are usually caps that hold the brushes in.
 
What kind of backing plate do you have. My pc used to do the same with a backing plate I made but I bought a Meguiars backing plate and it didnt bog down at low speeds anymore unless with pressure. Dont know why it did with one and not the other but works fine now.

No it shouldn't.

One of the reasons that it will overheat at slow speeds (after a 'long' time) is the cooling fan is connected to the drive shaft - hence, the slower the speed, the slower the cooling fan rotates and the machine will have a tendency to heat up. Also, the speed control makes the motor run faster or slower by controlling the voltage applied to the motor, but reducing the voltage (to reduce the speed) increases the current, which means that the motor will, again, overheat. This is why you are usually cautioned not to run at too slow a speed for too long a time.

Having said that tho, it doesn't sound like you are exceeding normal operating conditions, so it shouldn't be overheating.

I would have it checked by a technician or return it to the seller. It isn't going to get better on its own.
