Q: How to loosen a blade assembly stuck on the PHO20-82 planer?

If the blade assembly seems completely locked, it usually means that the clamping element 23 is stuck. The PDF of this manual recommends a specific technique to unlock this situation: Unlocking Procedure First, unplug the device for your safety. Use a wooden wedge or a rubber mallet to give a light tap to the clamping element 23. This action breaks the adhesion causing the blockage. Tap lightly — the manual emphasizes the importance of light taps rather than hitting hard, to avoid damaging the mechanism. Once the clamping element is slightly loosened, use your hex key (Allen key) to loosen the two fixing screws 25. You can then extract the planer blade 26 by pushing it sideways with a piece of wood. Tip: The key to use is a hex key (Allen) — not a Phillips screwdriver. If you do not have this tool, it is an additional reason for the apparent blockage.

Q: I have loosened 3 Allen screws on the blade of the PHO20-82, is this normal?

You are doing well. According to the manual for the Bosch PHO20-82, the standard process is to loosen the two fixing screws (number 25) by about 1 to 2 turns using the hex key for socket screws (number 24) . If you notice the presence of 3 Allen screws instead of 2, this can happen depending on the configuration or age of your machine. You can loosen all 3 without any problem, following the same principle: only 1 to 2 turns , not a complete loosening. Important before restarting: Once your adjustments are complete, make sure to tighten the fixing screws . The manual states: "Before putting the device back into operation, check that the fixing screws 25 are properly tightened." Also manually turn the blade head to ensure that the blade does not rub anywhere. If any of these screws prove very difficult to loosen, the manual recommends giving a light tap on the tightening element (number 23) with an appropriate tool to release it.
