My treadmill is Keys Fitness Health Trainer HT85. I first noticed that when I would turn it on, the belt would "kinda miss/skip and then, as I increased the speed, it would continue, but then the smell of burning rubber started.

With the limited description (although this might be all you know at this point), it would be really tough to tell exactly what it is.

Off the top of my head, there are a few possibilities that come to mind:
1. Your motor is burning out;
2. The belt between the motor and the roller which supports the conveyor belt needs to be replaced;
3. Your conveyor belt is misaligned and rubbing somewhere (could be fixed with an adjustment to the supporting rollers.
4. You are running too fast and going to hurt yourself !!!

I would suggest starting with number 3 and working backwards. There should be some sort of a guard that can be removed to expose the motor, drive belt for the rollers, and the rollers.

Examine the conveyor belt that you run on and make sure it isn't touching the side of the treadmill anywhere (both above on the running surface and below -- although if it is misaligned, it will probably be rubbing on both the top and bottom)

Check out the drive belt that is between the motor and the rollers that spin your conveyor -- if there is any wear or obvious signs of burn, replace the belt.

Third, your motor may be the issue. There are a multitude of reasons your motor may be giving off a burning smell, and I wouldn't even begin to try to diagnose that here. It would be best to bring it to a shop that would be able to diagnose and either fix it or get you a new one.

The last possiblitiy (#4) was really just for my benefit !!!

What kind of lubricant should I use for treadmill?

The owners manual of my Horizon Treadmill states the following:

EVERY 6 MONTHS OR 150 MILES
It is necessary to lubricate your treadmill running deck every six months
or 150 miles to maintain optimal performance of your treadmill. Once the
treadmill reaches 150 miles, the console will prompt you to lubricate the
treadmill. Only use lubricant provided by Horizon Fitness!
• Turn of the treadmil with the on/off switch, then unplug the
power cord at the wall outlet.
• Loosen both the rear roller bolts. (For best results, place two removable
marks on both sides of the frame and note roller position). Once
the belt is loosened, take the bottle of lubricant and apply it to the
entire top surface of the running deck. Tighten both rear roller bolts
(matching up the marks for proper position) to original position. After
you have applied lubricant, plug in the power cord, insert the safety
key, start the treadmill and walk on the belt for two minutes to spread
the lubricant.

Silicone Spray; it does a great job. Get it at any hardware store or Wal Mart. Just lift up the tread mill belt enough to get the spray nozzel under it and spray the rollers. No need to take it all apart. I do mine all the time.
