Hello everyone I am new to the forum and am posting to try and get a little advice. I recently purchased a used grizzly pin router this model to be exact its about 10 years old and the guy I bought it from had it sitting around for quite a while, apparently he moved his workshop several years ago and in the process the router got damaged and he never got around to fixing it. So I got a good deal on it and needless to say I’ve slowly but surely ben replacing parts and whipping everything back into working shape. So today I turn it on for the first time everything runs smooth and quietly as it should then I go try to lower the cutter head and nothing happens. Now 2 of the pieces I had to replace were the air regulator/oiler and the pneumatic footswitch that controls everything. So after some thinking I came to 2 conclusions either one its not working because of insufficient air flow or 2 because I purchased the wrong kind of footswitch. I know little to nothing about pneumatics so I essentially just used some educated guessing when it came to buying one, but from what I could gather they come in either a 4 way or 5 way switch so I took the pedal apart thinking maybe I could figure it out, well once I had it apart I saw there were inlets and outlets numbered 1-5 so I assumed this meant it was a 5 way switch so that’s what I ordered but alas it doesn’t work. So my question is does anyone else have any thoughts on what it might be? Any help would be greatly appreciated cause im out of ideas. Thanks

P.S Here is some pics of the main part of the footswitch if it helps.

NICE score

When I assembled my little Shop Fox, I bypassed the foot switch and put air directly to the line to insure the unit would raised and lowered, as it was supposed to. I didn’t apply full pressure, since I just wanted to insure things moved freely. From there, I was able to trouble shoot and address leaks and such.

Can you put a hose on the end of a blow gun, then press it to the different ports and watch the results?

Don’t know hydraulics either, but, for a three way light switch, you’d have four wires (excluding ground). One in from the source to feed the item, two across and one out to the load. So this might follow the same concept – five would equate to four (way), just as a three way is only good for two switches (positions).
