Maintaining the correct chain tension on your STIHL chainsaw is crucial for both safety and optimal performance. An improperly tensioned chain can lead to reduced cutting efficiency, increased wear and tear on your chainsaw, and even safety hazards. In this guide, we’ll provide clear and concise steps for tightening the chain on your STIHL chainsaw, ensuring it operates at its best.
Important Note: Before tightening your chainsaw chain, always make sure the engine is off, and the chainsaw is completely cool.
Safety First
Safety is paramount when working with chainsaws. Ensure you have the following safety gear:
- Protective eyewear
- Hearing protection
- Gloves
- Chain brake engaged (if applicable)
Check the Chain’s Condition
Before tightening the chain, it’s essential to inspect it for any signs of damage or wear. If you notice any issues such as damaged or dull chain links, address them first by sharpening or replacing the chain.
Locate the Chain Tensioning Screw
On STIHL chainsaws, the chain tensioning system typically involves a tensioning screw or knob. Here’s how to find it:
Side Tensioning Screw: If your chainsaw has a side tensioning screw, it’s usually located on the right-hand side of the saw, adjacent to the bar and chain.
Front Tensioning Knob: Some STIHL models have a front tensioning knob located on the front of the chainsaw near the bar and chain.
Refer to your chainsaw’s manual for specific information on the location and type of tensioning system your saw uses.
Adjust the Chain Tension
Follow these steps to properly adjust the tension of your STIHL chainsaw chain:
Loosen the Chain: If the chain is too tight, start by loosening it. For side tensioning screws, use a screwdriver to turn it counterclockwise. For front tensioning knobs, rotate it counterclockwise.
Check the Tension: Using a gloved hand, gently pull on the chain. The chain should move freely along the guide bar but should not sag beneath it. You should be able to lift the chain’s drive links about halfway from the bar.
Tighten the Chain: To tighten the chain, turn the side tensioning screw clockwise (or the front tensioning knob clockwise) in small increments. Check the tension frequently until it reaches the correct tightness as described above.
Final Check: Once the chain is properly tensioned, manually rotate it along the guide bar to ensure it moves freely without resistance.
Tighten the Bar Nuts
After ensuring the chain is correctly tensioned, don’t forget to tighten the bar nuts securely. Loose bar nuts can lead to chain tension issues and potential accidents. Use a wrench to tighten them according to your chainsaw’s specifications.
Conclusion
Maintaining the right chain tension on your STIHL chainsaw is a fundamental aspect of safe and efficient operation. By following the simple steps outlined in this guide, you can ensure your chainsaw is ready to perform at its best. Regularly checking and adjusting your chain’s tension not only improves cutting performance but also extends the lifespan of your chainsaw. Always refer to your chainsaw’s manual for specific instructions and guidelines. Remember that safety should be your top priority when working with chainsaws, so use appropriate protective gear and exercise caution at all times.
