Stihl Strimmer Head Removal: 5 Pro Tips for Arborists
Removing a strimmer head might seem like a straightforward task, but trust me, it’s easy to get it wrong. I’ve seen colleagues struggle, strip threads, and even damage their machines trying to force things. The key is to understand the mechanism, use the right tools, and approach the task methodically.
1. Safety First: The Unsung Hero of Strimmer Maintenance
Before you even think about touching your strimmer head, disconnect the spark plug. I can’t stress this enough. It’s the golden rule of any small engine repair. I remember once, a friend of mine, eager to get back to work, skipped this step. He accidentally bumped the throttle while fiddling with the head, and the engine sputtered to life. Luckily, he only got a scare, but it could have been much worse.
- Why is it so important? Disconnecting the spark plug eliminates the risk of accidental engine ignition. Even a brief start can cause serious injury if your hands are near the cutting head.
- How to do it: Locate the spark plug wire (usually a black rubber cap) and firmly pull it off the spark plug. Tuck the wire away from the spark plug to prevent accidental reconnection.
Think of it as your personal safety net. It takes seconds to do, and it could save you from a serious accident.
2. Know Your Enemy: Understanding Stihl Strimmer Head Types
Stihl offers a variety of strimmer heads, each with its own removal method. Knowing which type you have is crucial.
- AutoCut Heads: These are the most common type. They feature a bump-feed mechanism, where you tap the head on the ground to release more line. Removal usually involves inserting a tool (like an Allen wrench or screwdriver) into a hole in the head to lock the spindle while you unscrew the head.
- DuroCut Heads: These heads use pre-cut lengths of line that are inserted into the head. Removal is similar to AutoCut heads, but the locking mechanism might be slightly different.
- Fixed-Line Heads: These heads have lines that are permanently attached. Removal typically involves unscrewing the entire head assembly.
How to Identify Your Head:
- Check the Model Number: Look for a model number printed on the head itself. You can then search online for the specific removal instructions.
- Consult Your Owner’s Manual: Your owner’s manual should have detailed diagrams and instructions for your specific strimmer model.
- Visual Inspection: Compare your head to images of different Stihl heads online. Pay attention to the shape, locking mechanism, and line loading system.
My Personal Experience:
I once spent an hour trying to remove an AutoCut head using the wrong method. I was convinced it was a fixed-line head and was trying to unscrew the entire assembly. After much frustration, I finally consulted the owner’s manual and realized my mistake. Moral of the story: always know your equipment!
3. Arm Yourself: The Right Tools for the Job
Using the right tools is essential for a smooth and damage-free removal. Here’s what I recommend:
- Stihl Combination Wrench: This is a must-have for any Stihl owner. It has various sizes of wrenches and screwdrivers specifically designed for Stihl equipment.
- Allen Wrench Set: Many Stihl strimmer heads use an Allen wrench to lock the spindle.
- Screwdriver Set: A variety of screwdrivers (both flathead and Phillips) will come in handy for different models.
- Gloves: Protect your hands from dirt, grease, and sharp edges.
- Penetrating Oil: This can be a lifesaver if the head is stuck or corroded.
- Soft-Faced Hammer: Use this to gently tap the head if it’s stubborn.
- Eye Protection: Safety glasses or goggles will protect your eyes from flying debris.
Tool Selection Tips:
- Quality Matters: Invest in good-quality tools that won’t break or strip easily.
- Proper Fit: Make sure your tools fit snugly into the fasteners. Loose tools can damage the threads.
- Cleanliness: Keep your tools clean and free of rust.
Data-Backed Insight:
According to a study by the American Society of Agricultural and Biological Engineers, using the correct tools for equipment maintenance can reduce repair time by up to 30% and minimize the risk of damage by 40%.
4. The Removal Process: A Step-by-Step Guide
Now that you’ve got your safety gear on, identified your strimmer head, and gathered the necessary tools, let’s get down to the nitty-gritty. I’ll walk you through the general process, but remember to always consult your owner’s manual for specific instructions for your model.
General Steps for Removing a Stihl Strimmer Head:
- Secure the Strimmer: Place the strimmer on a stable surface, such as a workbench or the ground. Make sure it won’t roll or tip over.
- Locate the Locking Mechanism: This is usually a hole in the side of the head or a flat spot on the spindle.
- Insert the Locking Tool: Insert the appropriate tool (Allen wrench, screwdriver, or combination wrench) into the locking mechanism. This will prevent the spindle from rotating.
- Unscrew the Head: Most Stihl strimmer heads have a left-hand thread (meaning you turn it clockwise to loosen it). Use the appropriate wrench or your hand to unscrew the head.
- Apply Penetrating Oil (If Needed): If the head is stuck, spray some penetrating oil around the threads and let it sit for a few minutes.
- Use a Soft-Faced Hammer (If Needed): Gently tap the head with a soft-faced hammer to help loosen it.
- Remove the Head: Once the head is loose, carefully unscrew it completely and remove it from the spindle.
Specific Examples:
- AutoCut Head: Insert an Allen wrench into the locking hole, hold it firmly, and turn the head clockwise to loosen it.
- DuroCut Head: The locking mechanism may be a small lever that you need to press or slide. Consult your owner’s manual for the exact procedure.
- Fixed-Line Head: Simply unscrew the entire head assembly, usually with a wrench.
Troubleshooting Common Issues:
- Stuck Head: Apply penetrating oil and use a soft-faced hammer. If it’s still stuck, try using a heat gun to warm up the metal (but be careful not to overheat it).
- Stripped Threads: If you strip the threads, you may need to replace the spindle or the entire strimmer. Prevention is key: always use the right tools and avoid forcing things.
- Broken Locking Mechanism: If the locking mechanism is broken, you may need to replace the strimmer head.
A Story of Perseverance:
I once encountered a strimmer head that was so stuck, I thought I’d never get it off. I tried everything: penetrating oil, heat, hammering. Finally, I decided to try a trick I learned from an old mechanic: I wrapped a wet rag around the head and let it sit overnight. The moisture helped to loosen the corrosion, and the next day, the head came off with ease. Sometimes, patience is the best tool.
5. Maintenance Matters: Keeping Your Strimmer Head in Tip-Top Shape
Once you’ve successfully removed your strimmer head, don’t just slap a new one on and call it a day. Take this opportunity to clean and inspect the spindle and the head itself.
- Cleaning: Use a wire brush to remove any dirt, debris, or rust from the spindle and the head.
- Inspection: Check the spindle threads for damage. Make sure the locking mechanism is working properly. Inspect the head for cracks or wear.
- Lubrication: Apply a light coat of grease to the spindle threads before reattaching the head. This will prevent corrosion and make future removals easier.
Pro Tip:
While the head is off, inspect the deflector shield on your strimmer. This shield protects you from flying debris. If it’s cracked or damaged, replace it immediately.
Maintenance Schedule:
- After Each Use: Clean the strimmer head and spindle.
- Monthly: Inspect the head for wear and tear. Lubricate the spindle threads.
- Annually: Replace the strimmer head if it’s worn or damaged.
The Cost of Neglect:
Neglecting strimmer head maintenance can lead to several problems:
