Hello Terry Dugger, If it is suddenly stopping it could be a bearing problem... but if it is slowing down like a tired battery... DEPENDING VERY MUCH on what kind of battery you have (undisclosed model ...purpose tool)... "some" RECHARGEABLE BATTERIES develop a memory... and are reluctant to go BELOW that level. Typically these are seldom used tools... wiki does a pretty good description on these batteries (types). There are folks out there that think it is CLEVER to DISCHARGE these thing... or pulse them to BREAK THE MEMORY. Likely to case a fire or explode as to succeed... If you are suddenly using a tool that has been stored foe a while... you MIGHT notice the battery time is getting better... Else just buy a replacement battery... Cordless tools do not do well if stored incorrectly. Hope this helps. https://en.wikipedia.org/wiki/Memory_effect Nickelcadmium battery Porter Cable Home Amazon com porter cable batteries

Part is no longer produced. I am going to adapt a 6" dewalt pad by drilling new mounting holes. (The Dewalt pad has 4 holes.)

Piston not retracting is caused by several issues. Bent or broken driver, worn piston oring or loose or broken check seal. Remove head and examine driver for bent or broken, adjust as needed. Check that piston oring fits snug, piston should not drop down cylinder under its own weight. Pull cylinder from body and check that black band (check seal) is in place around holes in cylinder. Good luck

Here is a manual . Hope it helps http://powertool.manualsonline.com/manuals/mfg/portercable/7800_7801.html

Great video on youtube and pretty similar to the one you have How to Use Care for Finishing Sander How to Install Sand Paper in...

Have you lubricated either nail gun? If not, go to Home Depot and get a bottle of air tool oil. It's in tools by the compressors. Disconnect the air hose from the tool. Pour about a teaspoon of oil into the air inlet of the tool. Reconnect everything and try it 10-20 times with no nails in the tool. Then try it with nails. Good luck.

Any good quality general purpose grease should suffice. If you want a more detailed answer, you need to provide a little more information than just E77 edge sander. Brand, full model number (not the name), etc.

What is the model number of the motor?

To remove the collet (not the collet nut) you must first take apart the armature from the field. To do this, 1. Take the cap off the top by removing the two Phillips screws. 2. Remove the two brushes. 3. Remove the two Phillips screws hidden under the cap. 4.The only thing holding the top and bottom pieces now is a friction fit of the bearings. Tap with a non marking hammer on the top housing underneath the brush holders, and it should come apart after a few taps. 5.Use an armature split sleeve and put the armature sleeve in a vice to hold the armature. 6.Then use a wrench and unscrew the collet from the armature. 7. Just reverse this process to put it back together.

You must purchase a sub base (part number 42188) with a larger hole, it has a 2 1/2" hole, for the bit to fit through.
