Setup and Installation
Follow these steps to properly install the gearhead onto your brush cutter or trimmer shaft.
- Prepare the tool: Ensure your brush cutter is turned off, the engine is cool, and the spark plug wire is disconnected (or battery removed for electric models) to prevent accidental startup.
- Remove old gearhead (if applicable): If replacing an existing gearhead, carefully remove it by loosening any bolts or clamps securing it to the shaft. Note the orientation of the old gearhead for reference.
- Inspect shaft: Clean the end of the brush cutter shaft. Verify that your shaft has a 26mm outer diameter and a 9-tooth drive spline for compatibility with this gearhead.
- Attach new gearhead: Slide the new Liineparalle gearhead onto the brush cutter shaft. Ensure the 9-tooth spline inside the gearhead aligns correctly with the drive shaft.
- Secure the gearhead: Tighten the securing bolts or clamps on the gearhead firmly to the shaft. Ensure there is no wobble or play. Do not overtighten, as this can damage the shaft or gearhead housing.
- Final check: Once installed, gently try to rotate the gearhead by hand to ensure it moves freely and is securely fastened. Reconnect the spark plug wire or battery.

Operating Instructions
The gearhead itself does not have operational controls. Its function is to transmit power from the engine to the cutting attachment. Refer to your brush cutter's original instruction manual for specific operating procedures, safety guidelines, and proper use of cutting attachments.
- Attachment compatibility: Ensure any cutting attachments (e.g., trimmer line head, blade) are compatible with this gearhead and your brush cutter model.
- Pre-operation check: Before each use, confirm the gearhead is still securely attached and free from damage.
- Safe operation: Always operate your brush cutter according to the manufacturer's safety instructions, maintaining a safe distance from others and wearing appropriate PPE.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your gearhead.
- Cleaning: After each use, clean the exterior of the gearhead to remove grass, dirt, and debris. Use a damp cloth; avoid harsh chemicals.
- Inspection: Periodically inspect the gearhead for cracks, dents, or other signs of wear or damage. Check that all bolts are tight.
- Lubrication: The internal gears are typically pre-lubricated. If your gearhead has a grease port, consult your brush cutter's manual or a qualified technician for recommended lubrication intervals and grease type. Do not attempt to disassemble the gearhead for lubrication unless specifically instructed.
- Storage: Store the brush cutter with the gearhead in a clean, dry place, away from extreme temperatures and moisture.

Troubleshooting
If you encounter issues with your gearhead, refer to the following common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Gearhead does not fit shaft | Incorrect shaft diameter or spline count. | Verify your brush cutter shaft has a 26mm diameter and 9 teeth. This gearhead is not universally compatible with all models. |
| Excessive vibration or noise | Loose attachment, damaged internal gears, or unbalanced cutting attachment. | Check that the gearhead is securely fastened. Inspect for internal damage (if safe to do so, or consult a professional). Ensure cutting attachment is balanced and correctly installed. |
| Gearhead overheating | Lack of lubrication, excessive load, or internal friction. | Reduce operating load. If applicable, check lubrication (consult professional). Ensure no debris is obstructing cooling. |
| Cutting attachment not spinning | Drive shaft not engaged, internal gear failure, or attachment issue. | Ensure the gearhead is fully seated and secured on the drive shaft. Inspect the cutting attachment for blockages or damage. If internal gear failure is suspected, professional service is required. |
