All tooling maintenance should be performed in a clean environment. Any foreign matter on any of the tooling will detract from the tool accuracy. Verify that all cutters are AceCo brand cutters. AceCo does not recommend mixing cutters from different manufactures.

NEW CUTTERS:

Inspect all cutters, washers and nuts for damage that might have occurred during shipping.

  1.  Cutters:Verify that all thin cutters are of the same part number. If using thick cutters, ensure that all thick cutters are of the same part number.
  2.  Washers & Nuts:If using existing washers and nuts, inspect parts for galling on the top and bottom mating surfaces and inside of the threads. Galling occurs from torqueing the retaining nuts without use of anti-seize compound. Once the nuts/washers have been galled, they can no longer be accurately torqued and must be replaced. If the threads on the nut are damaged, the threads on the bolt will likely also be damaged.
  3.  Stone both index surfaces of each cutter with a fine grit India stone and light oil (WD-40). Use a circular motion to remove any burrs.
  4. Clean the inside bore of the hole with a Q-Tip (cotton swab). Remove oil with a shop towel and Isopropyl alcohol. It is imperative that there is no residual matter inside the bore of the cutter or on the index surface.
  5.  Place cutters on a clean surface and cover with a clean shop towel.
