2. Safety Information
Always prioritize safety when working with machinery. Failure to follow safety instructions can result in serious injury or damage to equipment.
- Personal Protective Equipment: Always wear appropriate protective clothing, including gloves and eye protection, when handling or installing the belt.
- Rotating Parts: Be aware of rotating parts within the snow blower. Keep hands, feet, and loose clothing away from moving components to prevent entanglement.
- Engine Off: Ensure the snow blower engine is completely off and cooled down, and the spark plug wire is disconnected before performing any maintenance or installation.
- Ventilation: Never operate the snow blower in an enclosed space to prevent carbon monoxide poisoning.
- Original Parts: Use only genuine PowerSmart replacement parts to ensure proper fit and performance.
3. Installation (Auger Belt Replacement)
This section outlines the general steps for replacing the auger belt. Refer to your specific snow blower model's owner's manual for detailed instructions and diagrams.
- Prepare the Snow Blower:
- Ensure the engine is off and cool.
- Disconnect the spark plug wire to prevent accidental starting.
- Position the snow blower on a flat, stable surface.
- Access the Belt Housing: Locate and remove the protective cover or housing that encloses the auger belt and pulleys. This typically involves removing several bolts or screws.
- Relieve Tension: Identify the tensioning mechanism for the auger belt. Loosen or disengage it to relieve tension on the old belt.
- Remove Old Belt: Carefully remove the old auger belt from the pulleys. Note its routing for correct installation of the new belt.
- Install New Belt:

- Place the new PowerSmart Auger Belt (model 302040079) onto the pulleys, following the exact routing of the old belt.
- Ensure the belt is seated correctly in all pulley grooves.
- Apply Tension: Re-engage or tighten the tensioning mechanism to apply proper tension to the new belt. The belt should be taut but not overly tight.
- Reassemble: Reattach the protective cover or housing.
- Test: Reconnect the spark plug wire. Start the snow blower and engage the auger to ensure the new belt operates smoothly and correctly. Listen for any unusual noises.
4. Operation (After Belt Replacement)
After replacing the auger belt, ensure the snow blower operates correctly before use.
- Initial Check: Before starting, visually inspect the belt for proper alignment and tension.
- Test Run: Start the snow blower in a clear area. Engage the auger control lever. The auger should spin smoothly without slipping or excessive noise.
- Monitor Performance: During initial use, pay attention to the auger's performance. If you notice any issues such as slipping, unusual vibrations, or reduced auger speed, stop the snow blower immediately and re-inspect the belt installation.
5. Maintenance
Regular inspection and maintenance of your auger belt will extend its lifespan and ensure optimal snow blower performance.
- Visual Inspection: Periodically inspect the auger belt for signs of wear, cracks, fraying, glazing, or stretching. Replace the belt if any damage is observed.
- Tension Check: Ensure the belt maintains proper tension. A loose belt can slip, reducing performance, while an overly tight belt can cause premature wear on the belt and pulleys.
- Cleanliness: Keep the belt and pulley area free from snow, ice, dirt, and debris. Accumulations can cause the belt to slip or wear unevenly.
- Storage: When storing the snow blower for extended periods, especially during off-season, ensure the belt is clean and dry.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Auger not spinning or spinning slowly | Loose or worn auger belt | Check belt tension and condition. Adjust tension or replace belt if worn. |
| Belt slipping | Incorrect belt tension, glazed belt, or debris on pulleys | Adjust tension. Clean pulleys and belt. Replace belt if glazed or damaged. |
| Unusual noise from belt area | Misaligned belt, worn pulley bearings, or foreign object | Inspect belt alignment. Check pulleys for wear. Remove any debris. |
If troubleshooting steps do not resolve the issue, consult a qualified service technician or contact PowerSmart customer support.
