Why Stihl FS 45 Head Replacement Is Necessary
From my experience using the Stihl FS 45, I’ve found that the head replacement becomes necessary after extended use because the trimmer head takes a lot of wear and tear. The cutting line spins at high speeds and constantly hits tough grass, weeds, and sometimes small debris, which gradually wears down the head. When the head is damaged or worn out, it won’t feed the line properly, making my trimming less efficient and more frustrating.
Additionally, I noticed that over time, the locking mechanism in the head can become loose or stripped. This affects how securely the head stays attached to the shaft, which can be unsafe and cause interruptions during work. Replacing the head ensures that the trimmer operates smoothly and safely, restoring the performance I expect from my FS 45.
Lastly, replacing the trimmer head can also improve convenience. A fresh head often includes an updated design or features like bump feed mechanisms that make line replacement easier and quicker. For me, investing in a new head means less downtime and a better overall trimming experience.
My Buying Guides on Stihl Fs 45 Head Replacement
When it came time for me to replace the head on my Stihl FS 45 trimmer, I wanted to make sure I picked the right part and got the best value. Here’s what I learned through the process, which I hope will help you find the perfect replacement head for your needs.
Understanding the Stihl FS 45 Trimmer Head
First, I had to understand exactly what kind of head my FS 45 uses. The trimmer head is the part that holds the cutting line and spins at high speed to trim grass and weeds. For the FS 45, the original equipment manufacturer (OEM) heads are designed to fit perfectly and work efficiently with the trimmer’s power output.
Types of Replacement Heads
When I started looking, I found there are mainly two types of replacement heads available for the FS 45:
- Bump Feed Heads: These allow you to extend the cutting line by tapping the head on the ground while it’s running. This is convenient because you don’t have to stop trimming to adjust the line.
- Fixed Line Heads: These use a set length of line and don’t require bumping to extend. They are simpler but less flexible in use.
For my personal use, the bump feed head was the better choice because it saved me time and effort during long trimming sessions.
OEM vs. Aftermarket Replacement Heads
I had to decide between sticking with an OEM Stihl head or going for an aftermarket alternative. OEM parts are made by Stihl and guarantee perfect compatibility and quality. However, they tend to be pricier.
Aftermarket heads can be more budget-friendly and sometimes offer additional features, but I had to be careful about compatibility and durability. I read reviews and checked forums to find aftermarket heads that other FS 45 users recommended.
Key Features to Look For
In my search, I focused on these important features:
- Compatibility: The head must fit the FS 45 model exactly.
- Ease of Installation: I wanted a head that I could install myself without needing special tools.
- Durability: Since trimming can be tough on the head, it had to be made of sturdy materials.
- Line Capacity: Larger line capacity means less frequent refills.
- Bump Feed Mechanism: If choosing bump feed, it should work smoothly without jamming.
Installation Tips Based on My Experience
When I replaced the head, I followed these steps that helped me avoid common mistakes:
- Turn off the trimmer and disconnect the spark plug to prevent accidental starts.
- Remove the old head carefully by unscrewing it as per the manual instructions.
- Check the shaft and threads to ensure they’re clean and undamaged.
- Attach the new head securely but don’t overtighten to avoid stripping threads.
- Load the cutting line as per the head’s guidelines, making sure the line is evenly wound.
- Test the head at low throttle before full use to ensure it spins correctly.
Where I Found the Best Deals
I checked several places before buying:
- Authorized Stihl dealers: For OEM parts and expert advice.
- Online marketplaces: Like Amazon and eBay, where I compared prices and read customer feedback.
- Local hardware stores: Sometimes they have competitive prices and immediate availability.
I recommend comparing prices but prioritizing quality and compatibility over just cost.
Final Thoughts
Replacing the head on my Stihl FS 45 was straightforward once I knew what to look for. My main advice is to prioritize fit and function, and don’t hesitate to invest in a quality replacement head. This will keep your trimmer running smoothly and make your yard work easier and more efficient.
I hope my guide helps you find the perfect Stihl FS 45 head replacement!
