| THIS COMPRESSOR IS SOMETHING I CAME ACROSS FROM THE SMALL ENGINE REPAIR WORLD. IT ACCUALLY WORKS BETTER THAN MY $140.00 OEM HONDA COMPRESSOR, BECAUSE THERE IS NOTHING IN THE WAY WHEN TRING TO REMOVE AND REPLACE THE COTTORS YAHOO !!! SEE ALL THE PICTURES BELOW FOR INSTRUCTIONS. ONE TINY ITEM WITH THIS COMPRESSOR, YOU MUST GRIND SOME OFF THE ONE ARM. SEE BELOW,, MAKE THE SMALLER ARM LOOK LIKE THE ONE ON THE COMPRESSOR IN THE PICTURE. IT TOOK ME ABOUT 45 SECONDS WITH MY 4 1/2" ANGLE GRINGER TO DO THIS. CLICK ON ANY OF THE PICTURES BELOW TO GET A LARGER VIEW. |
