What You'll Learn
Unplug the machine
Unplugging your Dewalt electric planer before beginning any servicing is crucial for your safety. The machine's powerful capabilities for shaping wood pose a severe risk to your hands if it accidentally activates during the blade-changing process. Thus, always ensure the machine is unplugged from its power source before proceeding.
It is also essential to be cautious when handling the blades. Even when they are not in use, the sharpness of the blades presents a hazard. Wear protective gloves when removing and installing blades to avoid accidental cuts. This simple precaution can provide an extra layer of safety during the procedure.
Additionally, it is important to be mindful of the blade's position. Before proceeding with any maintenance or repairs, ensure that the blade cylinder is locked in place. This will prevent any unintended movement of the blade, reducing the risk of injury. By following these safety precautions, you can minimise potential hazards and create a safer working environment.
Furthermore, it is worth noting that unplugging the machine is not only a safety precaution but also a recommended step in the blade-changing process. By unplugging the machine, you can proceed with the necessary steps for blade replacement without the risk of accidental activation. This allows you to focus on the task at hand and follow the step-by-step instructions for blade replacement with greater peace of mind. Remember to consult the owner's manual for specific instructions pertaining to your model of the Dewalt electric planer.
Overall, unplugging the Dewalt electric planer before changing the blades is a vital step that prioritises your safety and facilitates a seamless blade-changing process. By taking this precaution, you can work with confidence, knowing that the machine is completely deactivated, and reduce the chances of accidents or injuries during the procedure. Always remember to put safety first when working with power tools.

Unlock the blade thickness deck
To unlock the blade thickness deck of a Dewalt DW733 electric planer, follow these steps:
Firstly, ensure that the planer is unplugged from the power source before beginning any servicing. This is important, as accidental activation during the process could be dangerous. Next, grease the four slide posts and two screw lifts. Lower the deck and grease the four posts and two large threaded rods. After greasing, raise the deck and grease the bottom of the four rods and two threaded rods. Raise and lower the deck a few times until it moves smoothly. While you're at it, tighten the knob on the top of the machine that raises and lowers the deck.
Now, unlock the blade thickness deck and raise it to about 2.5 inches. Remember to lock the arm in place to prevent accidental movement. This step will provide some room above and below to manoeuvre and work safely on the machine.
After the blade thickness deck is unlocked and raised, the next steps would involve removing the cutting head cover, rotating the blade cylinder, and accessing the blade bolt heads. However, as the focus is specifically on unlocking the blade thickness deck, the detailed instructions end here.

Rotate the blade cylinder
Before rotating the blade cylinder, it is important to ensure that the power source of your Dewalt electric planer is disconnected for safety reasons. Once that is done, you can begin the process of rotating the blade cylinder.
Firstly, unlock the blade thickness deck and adjust it to a height of around 2.5 inches. This provides ample space to work on the machine without any obstructions. Remember to secure the deck at this height by locking the arm in place. Now, you can proceed to remove the cutting head cover at the rear of the planer. To do this, loosen the Allen screws located on each side of the cover using the Allen wrench, which should be included with the blade cover. Once the screws are loosened, carefully lift off and set the cover aside, making sure not to misplace the screws.
At this point, you are ready to rotate the blade cylinder. Rotate it until the blade bolt heads are easily accessible, and the cylinder locks securely in place. This step ensures that you can safely work on removing and replacing the blades. With the cylinder locked in this position, you can proceed to the next step of loosening and removing the bolts using the appropriate wrench.
It is important to note that safety should be a top priority when working with sharp blades and power tools. Always wear appropriate protective gear, such as gloves and eye protection, and ensure that the power source is disconnected before beginning any maintenance or repair work.

Remove the blade cover
To remove the blade cover, start by unplugging the Dewalt electric planer to ensure it is turned off and disconnected from any power source. This is crucial for safety reasons.
Next, locate the blade thickness deck and unlock it. Raise the deck to approximately 2.5 inches to create some space for manoeuvring and working safely. Remember to lock the arm in place to secure this position.
Now, you can begin removing the cutting head cover, also known as the blade cover, from the rear of the planer. Loosen the Allen screws on each side of the cover using the Allen wrench that should be included with the blade cover. Once the screws are loosened, carefully lift off and remove the cover, setting it aside in a safe place, ensuring you don't lose the screws.
With the blade cover removed, you will have access to the blade cylinder and blade bolts. From here, you can proceed to the next steps of changing the blades, such as rotating the cylinder and removing the bolts to access the blades.

Test the new blades
Once you've replaced the blades, it's time to test them out. Plug your planer in and take safety precautions by staying out of the way. Test the new blades by running a piece of wood through the planer. If there is kickback, heavy sniping, or the rollers do not engage, stop immediately. These issues may be due to incorrect adjustments, the blade sliding out of position, or the bolts not being tightened enough. Take a deep breath and redo the steps for each blade if necessary.
You can also test the new blades by looking at the results. A board that was previously run through a planer with dull blades will have significant tear-out. With fresh blades, the same board will have a smooth finish and will only need minimal sanding before being ready for finish.
Additionally, you can test the sharpness of the blades by feeling the edges with your finger. Compare the ends of the blades to the central area by dragging your finger across the edge to get a sense of how dull or sharp the blades are.
Another way to tell if the blades are dull is by the noise. The planer will be much louder if the blades are not sharp.

First, unplug the machine for safety. Then, unlock the blade thickness deck and raise it to about 2.5 inches, locking it in place. Remove the cutting head cover by loosening the Allen screws with an Allen wrench. Rotate the blade cylinder until the blade bolt heads are accessible, then use a wrench to loosen and remove the bolts. Remove the blade plate and replace the blade, then repeat the process in reverse to reassemble the planer.
You will need an Allen wrench, which should come with your planer, and a 10mm socket wrench or a ratchet wrench. You may also want to use gloves to protect your hands from the sharp blades.
