The Grizzly Lathe should be lubricated daily, or at least as often as it is used. Please refer to the [manual] for the correct lubrication instructions. While users are expected to perform basic cleanup and lubrication on a per-use basis, PS1 should, on a monthly basis perform the following maintenance operations:

  • clean
  • oil ways
  • lubricate gear mechanism according to manual's lubrication instructions
  • adjust gibs

noise in transmission/slippage - corrected belt tension by rehanging motor - main and spare belts are in good shape October 17, 2017 Jason
Drive belt tension failed. In rehanging motor, mounting hole stripped threads. Removed motor, and dismantled. Drilled and tapped housing 180deg from factory holes. Reassembled and rehung motor. Spindle runout is OK (checked by use, not with indicator) October 25, 2017 Tucker
