2. Safety Information
Always prioritize safety when operating heavy machinery and handling attachments. Read and understand all safety warnings and instructions before use.
- Personal Protective Equipment (PPE): Always wear appropriate PPE, including hard hat, safety glasses, steel-toed boots, and gloves.
- Machine Compatibility: Ensure that the attachments are compatible with your specific excavator or loader model. Refer to your machine's manual for attachment weight limits and hydraulic requirements.
- Pre-Operation Inspection: Before each use, inspect all attachments for damage, wear, loose bolts, or hydraulic leaks. Do not operate with damaged equipment.
- Secure Attachment: Always ensure attachments are securely connected to the quick coupler or pins are fully engaged before operation. Verify all locking mechanisms.
- Clear Work Area: Keep the work area clear of personnel, obstacles, and debris. Be aware of your surroundings and potential hazards.
- Hydraulic System Safety: Be cautious of high-pressure hydraulic fluid. Never attempt to repair hydraulic lines or components without proper training and depressurizing the system.
- Proper Operation: Operate the excavator and attachments smoothly. Avoid sudden movements, overloading, or using attachments for purposes they were not designed for.
- Storage: Store attachments in a stable, secure location to prevent accidental movement or tipping.

4. Setup and Installation
The MMS attachments are designed for easy installation, primarily utilizing the included quick coupler for efficient switching between tools.
4.1. Quick Coupler Installation
The quick coupler simplifies the process of attaching and detaching various implements. Ensure your excavator's arm is positioned correctly to align with the coupler's pins.
- Position the excavator arm to align with the quick coupler's mounting points.
- Insert the main pins through the excavator arm and the quick coupler. Secure with retaining clips or bolts as per your excavator's specifications.
- Connect any necessary hydraulic lines for the quick coupler if it is a hydraulic model. Ensure connections are tight and free of leaks.
- Test the quick coupler's locking mechanism to ensure it engages and disengages smoothly and securely.
4.2. Attaching Implements
Once the quick coupler is installed, attaching other implements is straightforward:
- Position the attachment on a flat, stable surface.
- Maneuver the excavator arm with the quick coupler to align with the attachment's pin holes.
- Engage the quick coupler's locking mechanism to secure the attachment. For manual quick couplers, insert and secure the pins. For hydraulic quick couplers, activate the hydraulic lock.
- For attachments requiring hydraulic power (e.g., Auger, Grapple), connect the hydraulic hoses from the attachment to the auxiliary hydraulic ports on your excavator. Ensure correct connection (pressure and return lines).
- Verify that the attachment is firmly secured before beginning any operation.

5. Operating Instructions
This section provides general guidance for operating each attachment. Always refer to your excavator's operating manual for specific controls and safety procedures.
5.1. Buckets (Narrow, Flat, Screening)
Buckets are used for digging, loading, and material handling. The narrow bucket is ideal for trenching, the flat bucket for grading and general excavation, and the screening bucket for separating materials.
- Digging: Position the bucket at the desired angle and use the excavator's controls to curl the bucket and lift the arm, scooping material.
- Loading: Curl the bucket to hold material, then swing the arm to dump into a truck or pile.
- Grading (Flat Bucket): Use the flat edge of the bucket to smooth and level surfaces.
- Screening (Screening Bucket): Scoop material and gently shake the bucket to allow finer particles to fall through the grates, separating larger debris.

5.2. Ripper
The ripper is designed for breaking up hard ground, asphalt, or other tough materials before excavation.
- Position the ripper tooth firmly against the material to be broken.
- Apply downward pressure and pull the ripper through the material using the excavator's arm and bucket cylinder controls.
- Repeat passes as necessary to loosen the material.
5.3. Rake
The rake attachment is used for clearing brush, debris, roots, and leveling uneven terrain.
- Lower the rake to the ground surface.
- Use the excavator's arm movements to pull or push debris, or to spread material evenly.
- The tines allow soil to pass through while retaining larger objects.

5.4. Grapple
The grapple is used for picking up, moving, and sorting irregular objects such as logs, rocks, and demolition debris.
- Position the grapple jaws around the object.
- Use the auxiliary hydraulic controls to close the jaws, securing the object.
- Lift and move the object to the desired location, then open the jaws to release.
5.5. Auger
The auger is used for drilling holes in the ground for fence posts, tree planting, or foundation piers. Ensure hydraulic hoses are correctly connected.
- Position the auger bit vertically over the desired drilling location.
- Slowly lower the auger while activating the hydraulic motor to begin drilling.
- Apply steady downward pressure. Periodically lift the auger slightly to clear soil from the hole and prevent binding.
- Once the desired depth is reached, reverse the auger rotation to extract it from the hole.

6. Maintenance
Regular maintenance extends the lifespan of your MMS attachments and ensures safe operation.
- Cleaning: After each use, clean dirt, mud, and debris from all attachments, especially around moving parts, pins, and hydraulic connections.
- Lubrication: Regularly grease all pivot points, pins, and bushings. Refer to your excavator's manual for recommended grease types and lubrication intervals.
- Inspection:
- Check for cracks, bends, or deformation in the steel structure.
- Inspect cutting edges and teeth on buckets and rippers for excessive wear or damage. Replace as needed.
- Examine hydraulic hoses for cuts, abrasions, bulges, or leaks. Replace damaged hoses immediately.
- Ensure all bolts and nuts are tight. Re-torque as necessary.
- Check pins and bushings for wear. Worn pins can lead to excessive play and reduced efficiency.
- Storage: Store attachments in a dry, covered area to prevent rust and corrosion. Elevate them off the ground if possible.
7. Troubleshooting
This section addresses common issues you might encounter with your MMS attachments.
| Problem | Possible Cause | Solution |
|---|---|---|
| Attachment does not fit quick coupler/pins. | Incorrect alignment; debris in pin holes; incompatible quick coupler. | Ensure precise alignment; clean pin holes; verify quick coupler compatibility with attachment. |
| Hydraulic attachment (Auger/Grapple) not operating. | Hoses incorrectly connected; insufficient hydraulic flow/pressure from excavator; clogged filter; damaged motor/cylinder. | Check hose connections (pressure/return); verify excavator hydraulic settings; inspect hydraulic filter; consult a qualified technician for internal component issues. |
| Excessive wear on cutting edges/teeth. | Abrasive material; improper operating technique; normal wear. | Adjust operating technique; replace worn parts as needed. |
| Attachment feels loose or has excessive play. | Worn pins/bushings; loose quick coupler mechanism; loose mounting bolts. | Inspect and replace worn pins/bushings; check quick coupler locking mechanism; tighten all mounting bolts. |
