In this video, we'll demonstrate how to replace the sandpaper on the Grizzly G0458Z and G0458 18-inch open-end drum sander, including helpful tips to ensure a smooth and successful replacement process.

We've also included step-by-step instructions below so you can follow along.

1. Unplug Power: Make sure the machine is unplugged from power before you begin.

• Flathead screwdriver
• 4mm hex wrench
• 5mm hex wrench
• Sharp utility knife
• New roll of 3-inch sandpaper

1. Unplug the machine from power.
2. Remove the bolts securing the top cover.
3. Remove the steel plate (if present).
4. Loosen the right side spring-loaded clamp. A flathead screwdriver may be used to gently free the sandpaper if the clamp is seated tightly.
5. Rotate the drum and carefully remove the sandpaper for most of its length.
6. Loosen the left clamp.
7. Fully remove the old sandpaper strip. Try not to rip or tear it if possible, as it can be used as a template.

1. Lay the old sandpaper strip flat.
2. Place the new roll of sandpaper next to it.
3. Use the old sandpaper as a guide to draw and cut the new sandpaper strip to the same dimensions and with the same angled cuts.

1. Cut a length of new sandpaper 86 inches long.
2. Measure 12 and a half inches from one end and cut from the corner to this 12 and a half inch mark.
3. From the same corner, measure 2 inches along the cut edge and make the next cut at a 90-degree angle.
4. Repeat this cut layout on the opposite side of the sandpaper strip, but mirrored.

1. Secure the angled end of the new sandpaper strip into the left clamp and tighten it.
2. Ensure that the angled side of the sandpaper is flush with the left drum edge. Overlapping may cause difficulty closing the cover.
3. Wrap the sandpaper strip around the drum, ensuring there are no bubbles or overlapping edges.
4. When the sandpaper reaches the right side of the drum, move it out of the way.
5. Using a 4mm hex wrench, insert the wrench into the access hole on the drum.
6. Rotate the drum towards you until the hex wrench rests on the top of the frame.
7. When you reach the end of the drum, ensure that the right clamp is open.
8. Insert the tag end of the sandpaper into the right clamp. The drum is spring-loaded to allow tension to be applied.
9. Twist the drum with one hand to apply tension.
10. Insert the tag end of the paper into the right clamp and tighten it down. You may need to notch the end of the sandpaper for a clean edge alignment.
11. Once the sandpaper is secured in both clamps and tensioned, remove the 4mm hex wrench.
12. Reinstall the steel plate (if removed).
13. Close up the top cover and secure it with the bolts.

• After removing the old sandpaper, clean the sanding drum with a solvent like acetone on a clean rag to remove any residue buildup.
• To help minimize paper movement during operation, consider using a very light coat of spray-on adhesive sparingly on the drum before applying the new sandpaper strip. This will help seat the strip.
