Specialized AirTool Pro floor pump
 

I've had a Specialized AirTool floor pump for the last 6 years and it has performed flawless, but lately I am getting a squeal when I push down on the handle. I noticed on the specialized site, they sell lube for the pump, but looking at the pump, I can not determine where the lube would go. and looking at it, I can't determine where the lube would be applied.

Does anyone know where to apply the lube for this pump? I can't find anything on the site, You Tube, etc....


Any help would be great.

If the pump has an air intake hole (near top of cylinder) add a drop there, and pump a few times rotting the handle to spread it around.

Many pumps don't have intake holes and the intake is the gap between piston rod (runs up to handle) and the guide bushing at the top of the pump. On these pull the handle up, add a drop between it and the bushing, then when you push the handle down it'll draw the oil in with the air. Again, pump a few strokes rotating the handle to spread it evenly.

Do not over oil your pump, it just pushes out extra oil with the air going into your tires.
