Stihl FS 40 Grass Trimmer Tips (5 Pro Woodcutting Hacks)

The Stihl FS 40 is a lightweight and versatile tool, primarily designed for trimming grass and weeds. However, with a few clever adjustments and techniques, you can push its capabilities further, even venturing into light woodcutting tasks. While it’s no substitute for a dedicated chainsaw, understanding these “hacks” can extend its utility and save you time and effort in specific situations. Let’s dive into the world of maximizing your Stihl FS 40’s potential, and then we’ll delve into the nitty-gritty of cost considerations for wood processing.

1. Mastering the Art of Line Selection for Light Woodcutting

The heart of any grass trimmer is its cutting line. For basic grass trimming, standard round line works fine. But to tackle tougher weeds and even light wood, you need to upgrade.

Square Line: This is my go-to for heavier weeds and thin brush. The sharp edges provide a more aggressive cut, slicing through thicker stalks with ease. I’ve used it to clear overgrown fence lines choked with brambles and small saplings (under ½ inch diameter).
Star Line (Multi-Sided): Similar to square line, but with more cutting edges. This provides even more aggressive cutting power. I’ve found it particularly effective for cutting through dense patches of nettles and other tough vegetation.
Reinforced Line: Look for lines reinforced with materials like aramid fibers. These offer increased durability and resistance to breakage, crucial when tackling woody stems.

Data Point: Aramid-reinforced trimmer line can cost 20-30% more than standard round line, but the increased lifespan and cutting performance justify the investment, especially if you frequently encounter tough vegetation or light wood.

Caution: Remember that the FS 40 is not designed for heavy woodcutting. Using overly aggressive line or attempting to cut thick branches can damage the trimmer head and motor.

2. The “Tapping Technique” for Controlled Cuts

Instead of trying to force the trimmer through wood in one continuous motion, use a “tapping” technique. This involves gently tapping the cutting line against the wood, allowing it to gradually wear through.

Angle of Attack: Experiment with the angle at which you approach the wood. A slightly angled approach can often be more effective than a direct, head-on cut.
Patience is Key: Don’t rush the process. Let the line do the work, and avoid applying excessive pressure.
Listen to Your Trimmer: Pay attention to the sound of the motor. If it starts to bog down or strain, ease off and adjust your technique.

Personal Story: I once used this technique to clear a patch of stubborn willow saplings that were encroaching on my garden. It took some time and patience, but I was able to remove them without resorting to a chainsaw.

3. Shield Modification (Use with Extreme Caution)

Warning: Modifying the shield is potentially dangerous and can increase the risk of injury. Proceed with extreme caution and only if you are comfortable with power tool modification. Always wear appropriate safety gear.

The standard shield on the FS 40 is designed to protect you from flying debris. However, it can also limit your ability to access tight spaces or cut at certain angles.

Careful Trimming: Consider carefully trimming away a small portion of the shield to improve visibility and access.
Prioritize Safety: Ensure the modified shield still provides adequate protection from flying debris.
Alternative: Instead of modifying the shield, consider removing it altogether (again, with extreme caution and only if you are experienced with power tools).

Important Note: Removing the shield significantly increases the risk of injury from flying debris. Always wear eye protection, gloves, and sturdy clothing when operating the trimmer without a shield.

4. Optimizing Engine Performance

A well-maintained engine is crucial for maximizing cutting power.

Fuel Mixture: Use the correct fuel mixture (typically 50:1) as specified in the Stihl FS 40 owner’s manual. Using the wrong mixture can damage the engine.
Air Filter: Regularly clean or replace the air filter. A clogged air filter restricts airflow and reduces engine performance.
Spark Plug: Inspect and replace the spark plug as needed. A worn spark plug can cause starting problems and reduce engine power.

Data Point: A clean air filter can improve fuel efficiency by up to 10% and extend engine life.

5. Mastering the Art of “Edging”

While not strictly woodcutting, the FS 40 can be used to create clean edges along sidewalks, driveways, and flower beds. This can save you time and effort compared to using a dedicated edger.

Tilt the Trimmer: Tilt the trimmer head at a slight angle to create a vertical cut.
Steady Hand: Use a steady hand and guide the trimmer along the edge.
Practice Makes Perfect: Practice in a less visible area to get a feel for the technique before tackling your main edging tasks.

Now that we’ve explored these hacks for maximizing your Stihl FS 40’s potential, let’s move on to the crucial aspect of cost considerations for wood processing and firewood preparation. This is where things get interesting, and where careful planning can save you a significant amount of money.
