Maintaining the proper tension on the chain of your STIHL chainsaw is crucial for safety and optimal cutting performance. In this article, we will provide clear and concise guidance on how to correctly tighten the chain, ensuring that both technical and non-technical users can follow the process.
1. Safety First:
Before you begin, always prioritize safety:
Ensure the chainsaw is turned off and the engine is cool.
Use safety gear, including gloves and eye protection.
2. Assess Chain Tension:
Proper chain tension is essential for safe and efficient operation. Here’s how to check it:
Lift the chainsaw’s guide bar and let the chain hang freely. The chain should remain on the guide bar, but you should be able to pull it with a gloved hand.
The chain should not sag excessively, but it should also not be overly tight, as this can cause damage.
3. Adjust the Chain Tension:
To adjust the chain tension, follow these steps:
Locate the chain tensioning screws or nuts on the side of the chainsaw, typically found near the guide bar.
Use the appropriate tool (usually a wrench or screwdriver) to turn the tensioning screws or nuts counterclockwise to loosen them.
Slightly tighten the chain by pulling up on the guide bar while turning the chain tensioning screws or nuts clockwise.
Check the tension again as described in step 2. The chain should still move freely but not sag.
4. Test the Chain:
After adjusting the tension, do a final test:
Rotate the chain by hand; it should move smoothly along the guide bar without resistance.
Try to pull the chain away from the guide bar; it should not come off the bar or easily detach.
5. Lock the Chain Tension:
Once you’ve achieved the correct tension, lock it in place:
- Tighten the tensioning screws or nuts securely in a clockwise direction. Be careful not to overtighten, as this can damage the chain or the chainsaw.
6. Check Again:
Recheck the chain tension one more time after securing it in place to ensure it hasn’t changed during the locking process.
7. Lubricate the Chain:
Proper chain lubrication is vital for chain life and smooth operation. Ensure your chainsaw’s automatic oiler is functioning correctly, or manually apply bar and chain oil.
8. Maintenance Schedule:
Regularly inspect and adjust the chain tension as needed, as it can loosen over time with use. Additionally, keep an eye on the chain’s sharpness and consider sharpening it when necessary for optimal cutting performance.
Conclusion:
Properly tensioning the chain on your STIHL chainsaw is a straightforward process that ensures safety and efficient cutting. Regularly checking and adjusting the chain tension, along with maintaining sharpness and lubrication, will help keep your chainsaw in top working condition. This not only enhances performance but also extends the life of your equipment.
