Instructions for oil removal from CUTECH and WAHUDA portable planers and jointer cutterheads

CUTECH and WAHUDA cutterheads are machined with a film of oil that may be left over from the process. Removing this oil residue, if apparent, is required before you use your new machine.


*** Be EXTREMELY CAREFUL when handling the knives or cutter tips as they are VERY SHARP!!! ***



  • Step 1 - Unplug the machine.
  • Step 2 - Place the planer or jointer at a comfortable working height and supply ample lighting. Remove the dust hood, guard, and any other covers necessary to expose the cutter head. See manual for helpful instructions.
  • Step 3 - Make sure you lay down rags on the bed of the planer to catch any residue from the cleaning process.
  • Step 4 - Cleaning of the cutterhead can be done using one of the following options:
    • Option 1 - Use an old nylon toothbrush and rags with solvent, such as mineral spirits or non-chlorinated brake cleaner, to clean off the oil. The knives are sharp, be careful not to cut yourself. Do not use anything hard or metal to clean with or you may chip the knives/tips. Use only rags with solvent, a nylon toothbrush, or perhaps a craft stick or a dowel wrapped with cloth to get into nooks. Use compressed air to dry and finish cleaning. Do not get solvent on any painted portion of the machine.
    • Option 2 - Using the supplied T-25 T-handle Torx tool, carefully remove the cutter tips or knives. Again, be EXTREMELY CAREFUL when handling the knives or cutter tips as they are VERY SHARP!!! Separate the knives/tips from the screws and place in separate containers with a bit of solvent. Once all are removed, wipe down the bare cutterhead using rags and mineral spirits or the brake cleaner. Once the oil is wiped off, use an air compressor or a can of pressurized air to clear each seat and screw hole on the cutterhead. This will aid in knife and cutter tips reinstallation. Place each knife in the seat and slightly snug each screw. Once you get a row of tips seated and slightly tightened down, repeat by going back over each cutter tip/knife and tighten down the screws securely to the torque specified in the owner’s manual.

Conclusion: After wiping off the cutterhead, wipe down any other crevices, rollers, or any other places where oil is visible. The object is to remove the grease before the machine is put into use. Use a sacrificial board after cleaning to test for remaining grease. If oil is still apparent, repeat whichever method you used above.


* NOTE: Remember to do the regular maintenance described in your manual. Planer rollers need to be regularly cleaned with a pitch remover that is safe for rubber surfaces to feed properly. Table surfaces on both planers and jointers need to be also cleaned and waxed periodically.
