4. Installation and Setup
Proper installation is crucial for the safe and efficient operation of your MMS Mini Excavator Ripper Attachment. Always ensure your excavator is turned off and secured before beginning installation.
- Verify Compatibility: Before installation, confirm that the ripper's span distance (90 mm/3.54in), hole diameter (25 mm/0.98in), and center wheelbase (90 mm/3.54in) are compatible with your specific mini excavator model (0.8-1.8 Ton). A tolerance of 1-3 mm is acceptable.
- Position the Ripper: Carefully align the ripper attachment's mounting points with the excavator's arm linkage.
- Insert Pins: Insert the two provided mini excavator pins through the aligned holes. Ensure they pass completely through both the ripper and the excavator's linkage.
- Secure with Nuts: Thread and tighten the two locking nuts onto the pins. Use appropriate tools to ensure they are securely fastened to prevent loosening during operation.
- Final Check: After installation, visually inspect all connections to ensure the ripper is firmly attached and there is no excessive play.

5. Operating Instructions
The MMS Mini Excavator Ripper is designed for high efficiency in challenging conditions. Always operate the attachment responsibly and safely.
5.1. General Operation
- Initial Engagement: Position the ripper's tooth at the desired starting point for excavation. Apply downward pressure using the excavator's hydraulics.
- Ripping Motion: Use a controlled pulling or prying motion to break up compacted soil, rock, or other materials. The hard serrated teeth are designed to effortlessly pass through tough ground.
- Material Handling: Once materials are loosened, the ripper can assist in moving or piling them, though a bucket may be more efficient for bulk material handling.
- Continuous Operation: The robust design and manganese steel material ensure the ripper can withstand high-intensity continuous operations, reducing labor costs.
5.2. Applications
The ripper's multifunctionality makes it suitable for a variety of tasks:
- Crushing Compacted Materials: Efficiently breaks up hard soil, weathered rocks, and other dense ground.
- Shredding Trees/Roots: Can be used to tear out stubborn roots and small trees.
- Breaking Up Gravel: Effective for loosening and preparing gravel surfaces.
- Removing Cracked Asphalt: Aids in the demolition and removal of damaged asphalt.
- Trench Filling: Can assist in breaking up soil for backfilling trenches.
- Housing Demolition: Useful for breaking smaller concrete or masonry elements.
- Slope Shaping: Helps in contouring and shaping terrain.

6. Maintenance and Care
Regular maintenance ensures the longevity and optimal performance of your MMS Mini Excavator Ripper Attachment.
- Cleaning: After each use, clean the ripper to remove dirt, mud, and debris. This prevents material buildup and corrosion.
- Inspection: Regularly inspect the ripper for signs of wear, cracks, or damage, especially on the tooth and welded areas. Pay close attention to the pins and nuts for any loosening.
- Lubrication: Ensure all pivot points on your excavator's arm linkage are properly lubricated as per your excavator's manual. While the ripper itself has no moving parts requiring lubrication, proper excavator maintenance is key.
- Storage: Store the ripper in a dry, protected area when not in use to prevent rust and environmental damage.
- Pin and Nut Check: Periodically check the tightness of the pins and locking nuts. Re-tighten if necessary to maintain a secure connection.
The high-quality manganese steel construction provides resistance to wear, corrosion, and deformation, contributing to an extended service life with proper care.
7. Troubleshooting
This section addresses common issues you might encounter with the MMS Mini Excavator Ripper Attachment.
| Problem | Possible Cause | Solution |
|---|---|---|
| Ripper feels loose or wobbly after installation. | Pins or locking nuts are not fully tightened. | Ensure excavator is off and secured. Re-tighten the locking nuts firmly. Check for correct pin insertion. |
| Difficulty attaching the ripper to the excavator. | Incompatible specifications; misalignment; debris in pin holes. | Verify ripper specifications against excavator requirements. Clean pin holes. Adjust excavator arm for precise alignment. |
| Ripper not effectively breaking up material. | Insufficient hydraulic pressure from excavator; incorrect operating angle; excessive wear on ripper tooth. | Check excavator's hydraulic system. Adjust the angle of attack. Inspect the ripper tooth for significant wear; replacement may be necessary if severely worn. |
| Unusual noises or vibrations during operation. | Loose attachment; damage to ripper or excavator linkage. | Immediately cease operation. Inspect all connections for tightness. Check the ripper and excavator arm for any visible damage or cracks. Do not operate if damage is found. |
