Wolfenden 420 Planer
Machine Workshop (Room G24)
Level 03 - Machine Certification


The planer or jointer is used to flatten, reduce the thickness of, and impart a smooth surface to a rough piece of lumber or timber. Using a sharp blade the planer shaves the material to produce horizontal, vertical, or inclined flat surfaces on workpieces which are usually too large for shaping. Special types of planes are designed to cut joints or decorative mouldings.

Health and Safety

  • The planer is a power tool that has the potential to cause serious injury if used incorrectly. Always exercise extreme caution when using the equipment. NEVER touch the blade or other moving parts during use. The blade can easily cut fingers and other body parts.
  • Familiarise yourself with the emergency stop buttons on the machine. Always turn the machine off when not in use. NEVER leave the machine unattended while in use.
  • Ensure the dust extractor gate is opened before use and closed when finished.
  • Use push sticks, fences and safety guards wherever possible.
  • Do not wear loose articles of clothing and/or jewelry when operating the bench saw.
  • Do not apply pressure directly towards the blade.
  • Do not try to remove jammed pieces while machine is still running.
  • Do not attempt to cut pieces shorter than 400mm.
  • Do not machine timber less than 15mm in thickness.
  • Do not allow fingers to trail down the side of the board.
  • Do not have hand close to front of board at start or at the back of the board at the end.
  • Please see workshop staff if there are any issues with the machines operation. Please do not attempt to make any adjustments without prior approval.

Operation Instructions

  • Turn on dust extractor: Turn on dust extractor and open the dust extractor gate.
  • Prepare the workspace: Ensure work area is clear and that all settings are correctly set. Ensure accessible space between guarding and blades is minimal All guides should be firmly attached and not removed during operations. See a staff member to unlock the machines power.
  • Machine material: Feed the material in a controlled and smooth motion through the planer. Use push sticks wherever possible.
  • Shut down and Remove material: Use the red mushroom switch to turn off the machine. Remove the material and clear away any dust and offcuts from both the machine and floor. See a workshop staff member to lock the machines power.

Workmanship Considerations

  • The planer is similar to the thicknesser in that they both surface the timber but each are used for a specific purpose. Planer flattens a face or straightens and squares edges. These flattened timbers can then be fed into a thicknesser to make them parallel and the same thickness.
  • The planer will make one side flat and perpendicular to its adjacent edges. This is great for squaring off twisted or bowed timber.
