Do you work for Slipcoat? Just curious because you seem to be saying that only slipcoat will work as a lubricant on treadmills. I have nothing against that brand, personally I don't use that one, but if it is a high quality treadmill lubricant, I am sure it will work great just like the many other brands of treadmill lubricant. I do take exception with "It is required for all institutional treadmills." because it is simply not true. Many, many treadmills do not need lubrication because they have a self lubricating belt. Those should never have lubricant applied to them under any circumstance. I have researched this quite a bit as I happen to have two self lubricating belt treadmills. Most say to do nothing, but others say to hold a clean, dry rag under the belt the same way I said to lube it, and let it clean off dust and small debris.
So please don't advise people using such a broad statement because you could really screw up someone who takes your word as gospel. Nothing against you, but these were the kinds of things that cost me a treadmill in the past. Treadmills are mostly the same parts, but different brands and different models are different and things done to one, may not work or may even actually hurt another one. I experienced this after a tech told me a way to generically tighten and loosen the belts on any treadmill. I ended up doing something against the manufactures suggestions, and ruined a treadmill belt. This was years and years ago, but since then, I have tried to really look into the treadmill I am fixing, and find out what the manufacture recommends with that specific model. Especially now a days where you can find all the manuals online, IMHO there is no need to take chances.
