Stihl FSE 60 Manual - Replacing Nylon Line
The Stihl FSE 60 is an electric string trimmer designed for efficient yard maintenance. A key maintenance task is replacing the nylon cutting line (trim line) in the cutting head. This guide covers safety precautions, tools needed, step-by-step replacement instructions for both single-line and dual-line heads, troubleshooting common issues, and proper line selection. Always refer to your official Stihl manual for model-specific details.
Safety Precautions
Always prioritize safety before performing any maintenance on your trimmer.
| Precaution | Description |
|---|
| Power Disconnect | Unplug the trimmer from the electrical outlet before starting any work. |
| Eye Protection | Wear safety glasses to protect from flying debris or broken line pieces. |
| Gloves | Wear work gloves to protect hands from sharp edges and heat. |
| Cool Down | Allow the trimmer motor and cutting head to cool completely if recently used. |
| Secure Work Area | Work on a clean, flat, stable surface. |
Tools & Materials Required
Gather these items before beginning the replacement process.
- Replacement Nylon Line: Correct diameter and type for Stihl FSE 60 (see Specifications section).
- Scissors or Line Cutter: To cut the nylon line to the proper length.
- Clean Cloth: For wiping the cutting head.
- Needle-Nose Pliers (optional): Helpful for pulling line through eyelets.
- Owner's Manual: For model-specific diagrams and references.
WARNING! Never use metal wire or other substitutes for nylon trimmer line, as this can cause severe injury and damage the trimmer.
Identifying Your Cutting Head Type
The Stihl FSE 60 may be equipped with different head types. Identify yours to follow the correct procedure.
- Single-Line Head (AutoCut C 2-4): Holds one strand of line. Typically has a "bump feed" mechanism—tap head on ground to advance line.
- Dual-Line Head (AutoCut C 5-2): Holds two strands of line. Also uses a bump feed system.
- Fixed-Line Head: Less common; requires manual unwinding and rewinding of spool.
Check Manual: Your trimmer's manual or the label on the head itself will specify the model.
Step-by-Step Replacement (Single Line Head)
- Step 1: Unplug the trimmer. Press the shaft lock button (if equipped) to prevent the spindle from turning.
- Step 2: Remove the cutting head cover by turning the locking knob counterclockwise or pressing the release tabs.
- Step 3: Remove the empty spool. Clean any debris from the spool cavity.
- Step 4: Cut a length of new line as specified in your manual (typically 10-15 feet).
- Step 5: Insert one end of the line into the anchor hole in the spool. Wind the line tightly and evenly onto the spool in the direction indicated by the arrow.
- Step 6: Leave about 6 inches of line unwound. Secure this end in the notch on the spool's rim.
- Step 7: Place the spool back into the head, ensuring it clicks into place. Pull the free end of the line out through the eyelet in the cutting head cover.
- Step 8: Reattach the cover securely. Pull on the line to release it from the spool's storage notch.
Step-by-Step Replacement (Dual Line Head)
For heads holding two lines.
- Unplug trimmer and engage shaft lock.
- Remove the cover and take out the two-section spool.
- Cut two equal lengths of line.
- Insert each line into its own anchor hole on the spool halves.
- Wind each line onto its respective spool section in the direction of the arrows, keeping tension even.
- Leave 6-inch leads and secure them in the storage notches.
- Reassemble the spool halves (they often clip together). Place back into head.
- Thread each line end out through its corresponding eyelet in the cover. Reattach cover.
- Pull both lines to release from storage notches. Trim ends to even length (approx. 8 inches total diameter).
Winding & Loading the Line
Proper winding is crucial for smooth feeding.
| Key Point | Instruction |
|---|
| Direction | Wind in the direction indicated by the arrow on the spool (usually clockwise). |
| Tension | Wind tightly and evenly to prevent tangles and ensure proper bump feed operation. |
| Alignment | Ensure lines do not cross over each other on the spool. |
| Storage Notch | Always secure the line ends in the notches before reassembly to prevent unwinding. |
| Eyelet Threading | Make sure the line passes cleanly through the eyelet without kinks. |
Common Problems & Solutions
| Symptom | Possible Cause | Corrective Action |
|---|
| Line won't feed | Line tangled on spool; line ends not released from storage notch. | Disassemble head, rewind line neatly. Ensure ends are pulled free after reassembly. |
| Line breaks frequently | Using incorrect diameter; hitting hard objects; old/brittle line. | Use correct line spec. Avoid fences, rocks. Replace with fresh line. |
| Head vibrates excessively | Uneven line lengths; damaged spool or head. | Trim both lines to equal length. Inspect spool for cracks, replace if damaged. |
| Line retracts into head | Line was wound in wrong direction. | Rewind spool in the correct direction as per arrow. |
| Motor runs but head doesn't spin | Shaft lock engaged; drive gear issue. | Disengage shaft lock. For gear issues, contact authorized service. |

- Inspect the line for wear during use and trim ends to maintain cutting efficiency.
- Store the trimmer in a dry place, out of direct sunlight to prevent line UV degradation.
