Introduction
This manual provides instructions for the installation and maintenance of Workmas Replacement Round Drive Belts for the Dremel 730 Belt Disc Sander. These belts are designed to ensure optimal performance and longevity of your Dremel 730 tool. Please read these instructions carefully before proceeding with installation or maintenance.
Product Overview

This image displays two new, blue, round drive belts. These belts are designed as replacements for the Dremel 730 Belt Disc Sander, ensuring proper power transmission for the tool's operation.
The Workmas Replacement Round Drive Belts are specifically manufactured for compatibility with the Dremel 730 Belt Disc Sander. They are crucial components for transmitting power from the motor to the sanding disc and belt, enabling the tool's functionality.
Setup and Installation
Safety Precautions
- Always disconnect the Dremel 730 Belt Disc Sander from its power source before attempting any maintenance or installation.
- Wear appropriate personal protective equipment, such as gloves, if necessary.
- Ensure the work area is clean and well-lit.
Belt Replacement Procedure
- Prepare the Sander: Place the Dremel 730 Belt Disc Sander on a stable, flat surface.
- Access the Drive Mechanism: Refer to your original Dremel 730 manual for specific instructions on how to access the drive belt compartment. This typically involves removing a cover or housing.
- Remove Old Belts: Carefully remove the worn or broken drive belts from their pulleys. Note the path of the belts for correct reinstallation.
- Install New Belts: Position the new Workmas replacement belts onto the pulleys. Ensure they are seated correctly and are not twisted. The belts should fit snugly but not be overly stretched during installation.
- Reassemble: Replace any covers or housing removed in step 2, ensuring all fasteners are securely tightened.
- Test Functionality: Reconnect the sander to its power source and perform a brief test run to ensure the belts operate smoothly without slipping or unusual noise.
Operating Considerations
After installing the new drive belts, the Dremel 730 Belt Disc Sander should operate as intended. Always follow the operating instructions provided in the original Dremel 730 manual for safe and effective use of the tool. Ensure that the sanding belt and disc are properly aligned and tensioned according to Dremel's guidelines.
Maintenance
Regular inspection of the drive belts is recommended to ensure optimal performance and prevent unexpected failures.
- Visual Inspection: Periodically check the belts for signs of wear, cracking, fraying, or stretching. Replace belts at the first sign of significant wear.
- Cleanliness: Keep the belt compartment free of dust, debris, and sanding residue, which can reduce belt life and efficiency.
- Storage: Store replacement belts in a cool, dry place away from direct sunlight and extreme temperatures to preserve their material integrity.
Troubleshooting
If you experience issues after replacing the drive belts, consider the following:
- Belt Slipping: Ensure the belts are correctly seated on the pulleys and that the pulleys themselves are clean and free of grease or debris. If slipping persists, the belts may be stretched or the pulleys worn.
- Unusual Noise: Verify that the belts are not rubbing against any internal components. Check for proper tension; belts that are too tight or too loose can cause noise.
- Sander Not Operating: Confirm that the power supply is connected and functional. If the motor runs but the belt/disc does not move, the belts may be broken or completely dislodged.
For issues beyond belt-related problems, consult the original Dremel 730 user manual or contact Dremel customer support.
