Before you start adjusting the blades of your planer, you should clean them. After that, start turning the screws in the gauge between the blades. To do that you need to turn them anticlockwise and keep doing that until they touch the end of the notches. The gauge plate can be tightened or loosened to your preference. After you’ve finished that, secure all the screws both inside and at the top of the adjusting screw.
