What You'll Learn
Unjamming the device
The first step is to put on some gloves to avoid getting pencil lead on your hands. Take a picture of the sharpening chamber before removing it from the outer plastic case. This will help you remember how the insides are arranged. Gently slide out the sharpening chamber from the casing. Some sharpeners might have an extra covering screwed around the sharpening blades, which can be removed with a screwdriver. Be cautious of the sharp blades when removing this cover. Once the cover is removed, you should be able to access the jammed object. Try to remove the object with your fingers, or use a knife or screwdriver to gently pry it out. You can also turn the sharpener upside down and shake it to dislodge the jammed object.
After removing the jammed object, remember to take pictures of the sharpener's pieces while putting it back together. This will help you reassemble the sharpener correctly. First, line up the flexible plastic part of the cord with the groove on the casing. Ensure that the bottom cover fits flush with the bottom of the sharpener. Reattach the bottom cover and screw it in place. Finally, stick the foot pads back over the screw holes. If the stickiness has worn off, use superglue to secure them. Plug in the sharpener and test it out.
Additionally, it is essential to perform regular maintenance on your Jakar electric pencil sharpener to prevent clogging and other issues. Empty the shavings tray frequently to avoid overfilling, which can cause the unit to become plugged. You can also unplug, disassemble, and lubricate the motor or shaft annually, unless it has sealed bearings. Refer to the owner's manual for specific instructions. If the blade becomes dull, you can try sharpening it with a small file or replace it with a new one.

Replacing the blades
To replace the blades of the Jakar electric pencil sharpener, you must first purchase a spare blade designed for this sharpener. You can find these blades online at art supply stores. Once you have a replacement blade, follow these steps:
Step 1: Put on Gloves and Take Pictures
Put on gloves to avoid getting pencil lead on your hands. Take pictures of the sharpener from multiple angles to understand its assembly better.
Step 2: Remove the Foot Pads and Screws
Turn the sharpener over and locate the screw holes, which are usually hidden under stick-on foot pads. Remove the foot pads and then use a screwdriver to unscrew the screws.
Step 3: Slide Out the Sharpening Chamber
Gently slide out the sharpening chamber from the outer plastic casing. Be cautious of the sharp blades inside. Take pictures of the screws and covering before removing them with a screwdriver if there is an extra covering over the blades.
Step 4: Remove the Old Blade and Insert the New Blade
With the sharpening chamber exposed, carefully remove the old blade, being mindful of its sharpness. Install the new replacement blade in its place, ensuring it is secure and correctly positioned.
Step 5: Reassemble the Sharpener
Refer to the pictures taken earlier to guide you in reassembling the sharpener. Slide the sharpening chamber back into the outer casing, ensuring the grooves align correctly. Reattach the bottom cover and screw it in place. Apply superglue to the foot pads if needed and stick them back over the screw holes.
Step 6: Test the Sharpener
After reassembling the sharpener, plug it in and test its performance. Ensure it sharpens pencils effectively and there are no obstructions.
Always refer to the official instructions provided by the manufacturer for replacing the blades of your specific Jakar electric pencil sharpener model. These instructions may vary slightly depending on the sharpener's design.

Testing the electrical cord and motor
If your Jakar electric pencil sharpener is not working, it could be due to a faulty electrical cord or a malfunctioning motor. Here is a step-by-step guide to testing and troubleshooting these issues:
Testing the Electrical Cord:
- Unplug the Sharpener: Before beginning any repairs or testing, ensure the pencil sharpener is unplugged from the power outlet for safety.
- Inspect the Cord: Visually inspect the electrical cord for any signs of damage, such as fraying, exposed wires, or burn marks. If the cord appears damaged, it will likely need to be replaced.
- Use a Multimeter: To test the continuity and integrity of the electrical cord, use a multimeter. Set the multimeter to test for continuity, and place the probes at each end of the cord to check for connectivity. A broken or faulty cord will show no continuity.
- Check the Power Outlet: Ensure that the power outlet you are using is functional by plugging in another device to test it. This will help determine if the issue is with the outlet or the sharpener.
Testing the Motor:
- Disassemble the Sharpener: Turn the sharpener over and look for screw holes, which are often hidden under stick-on foot pads. Remove the screws and carefully disassemble the sharpener, taking pictures as you go to aid in reassembly.
- Access the Motor: Once inside, locate the small electric motor. It is connected to the blade assembly and is typically mounted near the sharpening chamber.
- Test the Motor: With the sharpener unplugged, use the multimeter to test the motor for continuity. Place the probes on the motor terminals. If there is no continuity, the motor may be faulty and need replacement.
- Clean and Lubricate: If the motor seems functional, it may just need cleaning and lubrication. Use canned air or a soft brush to remove any debris or pencil shavings from the motor. Then, according to the owner's manual, lubricate the motor or shaft, unless it has sealed bearings.
If the electrical cord and motor are both functioning properly after testing and cleaning, reassemble the sharpener and test it again. If it still does not work, the issue may lie elsewhere, such as with the blade or other internal mechanisms. In that case, further troubleshooting or professional repair may be necessary.

Cleaning and lubricating
If your Jakar electric pencil sharpener is not working properly, it may be jammed. Before attempting to fix it, put on some gloves to avoid getting pencil lead on your hands.
- Take pictures of the sharpener and its pieces while dismantling it. This will help you remember how to reassemble the sharpener correctly.
- Turn the sharpener over and look for screw holes, which are usually hidden under stick-on foot pads. Remove the foot pads and screws with a screwdriver.
- Remove the sharpening chamber by gently sliding it out of the outer plastic casing. Grip the insides of the sharpener and pull the chamber out.
- Some sharpeners have an extra covering over the sharpening blades. Use a screwdriver to remove this covering. Remember to take pictures of the screws and cover before removing them.
- Be cautious of the sharp blades. Use a knife or screwdriver to carefully pry out any jammed objects. You can also try pulling out the object with your fingers, turning the sharpener upside down and shaking it, or blowing into it.
- Once the jammed object is removed, clean the sharpening chamber and blades with a soft brush or cloth. You can also use compressed air to blow away any remaining debris.
- After cleaning, apply a small amount of lubricant to the blades and moving parts of the sharpening mechanism. You can use a silicone-based lubricant or a dry lubricant designed for small machinery.
- Wipe away any excess lubricant with a clean cloth. Ensure that the lubricant does not come into contact with the pencil lead or graphite, as it may affect the performance of the sharpener.
- Reassemble the sharpener by following the pictures you took earlier as a guide.

Reassembling the sharpener
Once you have identified and resolved the issue with your Jakar electric pencil sharpener, you can reassemble the unit. If you took pictures during the disassembly process, refer to them to guide you. First, ensure that you have correctly addressed the problem. For example, if the issue was a dull blade, confirm that you have sharpened or replaced it. If the problem was a clogged shaving tray, make sure that you have emptied it.
Next, slide the sharpening chamber back into the outer plastic casing. There should be grooves to guide you, and the hole where the pencil is inserted should line up correctly when viewed from the top. Then, place the flexible plastic part of the cord into the groove on the casing. This step ensures that the bottom cover can fit flush with the bottom of the sharpener. After that, reattach the bottom cover and screw it back into place. Finally, stick the footpads back over the screw holes. If the adhesive has worn off, use superglue to secure the pads.
Plug in your sharpener and test it out. If you have completed all the previous steps, your Jakar electric pencil sharpener should now be working. Remember to teach your kids not to put the eraser end of the pencil into the sharpener!
