Setup and Installation
Proper installation is crucial for safe and effective operation. Refer to your brushcutter's manual for specific instructions on removing the existing head and attaching accessories.
- Safety First: Ensure your brushcutter's engine is off and the spark plug cap is disconnected before beginning installation.
- Remove Old Head: If applicable, remove the existing trimmer head according to your brushcutter's manufacturer instructions. This usually involves locking the shaft and unscrewing the head.

Operating Instructions
Once installed, the Oregon Jet Fit trimmer head is ready for use. Always follow your brushcutter's operating guidelines.
- Pre-Operation Check: Before starting, inspect the trimmer head for any damage, ensure lines are properly inserted and of equal length, and verify all fasteners are tight.
- Starting the Brushcutter: Follow your brushcutter's manual for starting procedures.
- Trimming Technique: Use a sweeping motion to cut grass and weeds. Avoid hitting hard objects like rocks, fences, or concrete, as this can damage the lines or the head.
- Line Wear: The Flexiblade lines are designed for durability, but will wear down with use. When lines become too short or ineffective, replace them as described in the "Setup and Installation" section.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your Oregon Jet Fit trimmer head.
- Cleaning: After each use, clean the trimmer head to remove grass clippings, dirt, and debris. A stiff brush or compressed air can be used.
- Inspection: Periodically inspect the aluminum head for cracks, bends, or excessive wear. Check the line insertion points for any damage.
- Line Storage: Store unused Flexiblade lines in a cool, dry place away from direct sunlight to maintain their flexibility and strength.
- Fasteners: Ensure all nuts and bolts securing the head to the brushcutter are tight. Re-tighten if necessary.
