To install the Stihl TrimCut 51-2 head, first ensure the trimmer is turned off and disconnected from any power source. Remove the existing head by unscrewing it. Align the TrimCut 51-2 with the shaft and screw it on in the opposite direction of normal operation. Make sure it is securely fastened before use.
The Stihl TrimCut 51-2 is compatible with nylon line of 2.0 mm to 2.4 mm in diameter. It is recommended to use genuine Stihl line for optimal performance and durability.
To prevent line breakage, ensure the line is wound correctly and not twisted. Avoid hitting hard surfaces while trimming and use the correct line diameter for your trimmer. Always use fresh line and replace it when it becomes brittle.
To load new line, first cut two equal lengths of line. Insert each line into the holes on the spool, winding them in the direction indicated by the arrows. Ensure the lines are evenly distributed and extend from the eyelets before securing the spool back into the head.
If the line is not feeding properly, check for tangles or jams in the spool. Ensure the line is wound in the correct direction and that it is not too tight. Also, inspect the eyelets for damage or blockages.
Regular maintenance includes cleaning the head after each use, checking for worn parts, and replacing the line as needed. Store the trimmer in a dry place and periodically inspect the head for any damage or wear that could affect performance.
The TrimCut 51-2 is designed to fit most Stihl trimmers, but compatibility may vary. Always refer to your trimmer’s manual or consult with a Stihl dealer to ensure compatibility with your specific model.
Excessive vibration can be caused by an improperly balanced head or damaged components. Check to ensure the line is evenly wound and that the head is securely attached. Inspect for any broken parts and replace if necessary.
The frequency of line replacement depends on usage and the type of vegetation being cut. Replace the line when it becomes brittle or if it frequently breaks. Regular inspection can help determine when a replacement is needed.
Signs that the TrimCut 51-2 head needs replacement include visible cracks or damage, difficulty in line feeding, excessive vibration, and if the cutting performance is noticeably reduced. If any of these occur, consider replacing the head.
