Default Porter & Cable 690 Maintenance Question

Hi ya'll. Newbie Matt from Toronto here.

Bought this used PC690, used once 5 years ago. Great shape BUT the adjustment bar is super sticky and won't slide unless wiggled vigorously.

The owners manual says that nothing ever needs to be lubricated but I assumed that meant just the plunge mechanism.

Any reason that I can't lightly sand the metal bar with 400 grit and then oil it?

Any thoughts? Thank you!

I would try cleaning it and using a lube on it that dries non sticky. Oil and grease may work temporarily but will make things worse in the long run. And welcome by the way Matt. Lots of fellow Canucks here on the forum.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

clean it, clean everything connected w/ it and put dry lube film on such as Triflow for your lubricant..... and there are a lot of them...
it must be dry lube or you will open a can worms you'd best want to have left closed...
no WD40 either... that's spilling over more cans of worms..

Default Dry Lubes...

VOE says WD is a mistake and all myth... it's a wet something or another that attracts all kinds of trash... does way more harm than good in the scheme of things... I've a lot of money cleaning/fixing/replacing/repairing after the fact...
It makes for a humongous mess [remember this come finishing time] and if it gets into an electric motor kiss the motor goodbye... It's also prone to flash fire and really doesn't work all that well on anything but it's convenient...
I'm real partial to Triflow but most any dry lube will work well providing it's has Teflon/PFTE in it... [higher percentage by volume is more gooder]...

CRC, Tiolube, KG and DuPont each have several most excellent industrial spec DRY SOLID FILM lubricants..

Criteria - dries dry to the touch, high pressure load bearing, contains Teflon/PFTE, barrier forming, extreme temperature range, [usually -100 to +500F] isn't hygroscopic, does not collect dirt, not flammable in dry state, chemical resistant, does not contain silicone, has a long list of compatibles and is really very long lasting... better said, it has all the of features WD hasn't got any of....

one thing about dry solid film lubricants is that when you apply them and you think that you didn't apply enough you have probably applied too much.. very, very little goes a loooooooooooooooong way...

Just wait until you do your saw's arbor mechanism w/ dry lube.. you and your saw will never be the same... You'll treat everything that moves in the shop in short order... Please thoroughly clean whatever before lubing..

It's a great release agent too...

Dry Film Lubricants are high performance coatings made up of very fine particles of lubricating agents blended with binders and other special additives. Once cured, these lubricating agents bond to the part surface as a solid film which reduces galling, seizing and fretting and protects against corrosion. Through the combination of these properties, dry film lubricants greatly improve the wear life of coated parts.
Dry film/solid film lubricants allow for operating pressures above the load-bearing capacity of normal greases and oils. They are also less prone to collecting soil particulates than greases and oils. In some applications, the coating is self-burnishing, leading to improved, rather than decreased, performance over time. Some blends of dry film/solid film lubricants are also temperature and chemical resistant allowing for their use in harsh environments such as jet engines where exposure to aviation fuel and extreme temperatures are the norm.

Dry lubes....

Be careful Matt, Stick can flood you with so much useful, and I DO MEAN USEFUL, information you might be sorry.

Welcome to our little corner of the 'net from another Canuck... a bit closer to you than Chuck is.
