1410 saw question and damn you Ernie

Just picked up my Porter-Cable 1410. Haven't even plugged it in yet as there are drops of oil on the base. A call to customer service didn't result with much other than that there is no oil, only grease used on it and recommending that maybe should I return it for another.

I did come across a review where someone received 2 1410s and both had drops of oil on them. My question, is this really a problem or perhaps just a lubricant coating used as a protectant (my spell check says this isn't a word so forgive me) for packaging etc.

So how many of you that have a 1410 have noticed this and any opinions you have of this.

And as for you Ernie. Due to your enthusiasm, I've already dropped almost 5 bills on a dry cut and will probably add another 17 on a Thermal Arc. Money that could be used for like.. food.. and stuff. Will you stop being so enthusiastic about stuff. Some of us are very impressionable you know. And just in case you were thinking, no I'm not interested in any land you may be trying to sell in Florida.

Actually I have his fine bridge. Barely used even. I can make you a fine deal, but you will have to act real fast since I do have another interested buyer.

Have to ask - what is the difference between oil and grease - ? density or thickness... Grease will drip and it also changes states from time to time.

I suspect that the saw was in a Semi-Trailer for some time - they get HOT. Either the grease would vaporize or drip or stay there. Depending on the temp grade it is.

If you ever ship your house goods across country - you will find that it gets cooked nicely. In fact, any silverfish or the like - are toast!

I would not be worried at all. The only thing I would look at is where did it drop from - (remember packing) - is an area depleted ?

I suspect any you see or get will be just the same.

That's just what I was thinking, but Porter-Cable customer service didn't seem aware of this. So I'm trying to get some real world experiences from the folks here. I know the 1410 uses reduction gearing to slow the blade RPM down which uses a couple more bearings. But I'd think these would be sealed bearings. So again, I just don't know. These have been out long enough that I'd think this would be well known by now if it's a problem or not. Any other thoughts welcome.

Wel I have never seen a drip of oil from my 1410, and it has gotten quite warm on ocassion, when working in the sun in the summer.

I have a Dewalt Dry Cut saw and jammed the blade on a piece of stock. This caused the blade shaft to move ever so slightly against the housing and the fan would catch and the saw would not turn. I had to disassemble the whole saw and fix the problem. The Dewalt uses an extremely expensive grease. It costs me over $50 for a small jar to reassemble the saw.

Grease is an oil suspended in a wax.

temp grade it is.

Simplified explanation: Lubricating greases are oils (usually) in a soap. The oils are carried by the soap and released in service as the grease is worked. Heat will soften the grease both by softening the soap matrix and by thinning the oils in solution. As the oils are depleted, you are left with the used grease gunk, which is mostly the soap matrix, but will also have any picked up contaminants and the reaction products of any reactive components of the grease-- often salts, as traditional greases are alkaline in character, and will neutralize small quantities of acids. When a 'lithium' grease or a 'sodium' grease is specified, this indicates the type of soap base. Moly grease has molybdenum disulfide added (a very good solid lubricant that plates to many metals and reduces contact wear)

To a chemist or biologist, greases have a particular set of chemical properties that I don't remember off the topof my head.

Upon closer inspection with better light today, I've noticed that the small and large blade guards slide against each other as they open. These are machined surfaces, and are coated with a viscous clear lubricant similar to petroleum jelly, by just smearing on.

I'm still curious as to how this contacted certain parts. But I think it may be a good chance that this is the source.

Will make a couple more phone calls, but not going to sweat it now.

Sealed bearing - hum come by air - lost pressure and popped the top. One can never say - the bearing might have been slightly off center or off axis - so the side pressure might have over heated and popped.

I'm not sure a soap is used.

In a cracking tower where one heats crude on the bottom and take different octanes from mid high to 3/4 up and the low pressure liquids then gases up there and on the bottom rings are the heavy grease then oils then gases....

Perhaps the new non-oil type oil might be in a paraffin (they strip that out at the well head the best they can since it coats the pipes and a pig has to clean the pipe.....)

Soaps and such will break down grease - I think the Lithium base is a little different.

I found the service people so useless at porter cable that I will not even consider there product again, and haven't. Ed
