Safety Information

Setup and Installation

Follow these steps to properly install the guide bar and saw chain onto your compatible Stihl chainsaw.

1. Prepare Chainsaw: Ensure the chainsaw is turned off, the spark plug cap is disconnected (for gasoline models), and the chain brake is engaged.
2. Remove Old Components: Loosen the bar nuts and remove the clutch cover. Carefully remove the old guide bar and saw chain, if present.
3. Install New Chain: Place the new Oregon 75LGX saw chain onto the clutch drum sprocket, ensuring the cutting edges are facing the correct direction (usually forward on the top of the bar).
4. Mount Guide Bar: Slide the Oregon 16-Inch Pro-Lite guide bar over the bar studs. Align the chain drive links with the guide bar groove.
5. Engage Tensioner: Ensure the guide bar's tensioning pin engages with the hole in the guide bar.
6. Replace Clutch Cover: Reinstall the clutch cover and hand-tighten the bar nuts.
7. Adjust Chain Tension: While holding the tip of the guide bar up, adjust the chain tensioning screw until the chain is snug against the bottom of the guide bar, but can still be pulled freely by hand. The chain should not sag underneath the bar.
8. Tighten Bar Nuts: Firmly tighten the bar nuts to secure the guide bar in place.
9. Final Check: Verify the chain moves freely and has proper tension. Reconnect the spark plug cap.

Operation

Once the bar and chain are correctly installed and tensioned, ensure your chainsaw is properly fueled and oiled before starting. Always follow your chainsaw's operating instructions.

• Chain Lubrication: Confirm the chainsaw's automatic oiler is supplying oil to the bar and chain. A dry chain can quickly damage both the chain and guide bar.
• Cutting Technique: Use proper cutting techniques to avoid kickback and ensure efficient cutting. Let the chain do the work; do not force the saw.
• Monitor Chain Tension: Periodically check chain tension during operation, especially during the first hour of use, as new chains can stretch. Adjust as needed.

Maintenance

Regular maintenance is crucial for the performance and longevity of your Oregon guide bar and saw chain.

• Chain Sharpening: Sharpen the saw chain regularly. For the Oregon 75LGX chain, use a 7/32-inch (5.5mm) round file. Maintain consistent angles and depth gauge settings. A sharp chain cuts efficiently and reduces wear on the chainsaw.
• Guide Bar Maintenance:
  • Clean Groove: Regularly clean the guide bar groove to remove sawdust and debris that can impede chain movement and oil flow.
  • Rotate Bar: To ensure even wear, rotate the guide bar periodically (e.g., after every few hours of use or chain sharpening).
  • Check Rails: Inspect the guide bar rails for burrs or uneven wear. File down any burrs to maintain smooth chain travel.
  • Lubricate Sprocket Nose: If your Pro-Lite bar has a sprocket nose, ensure it is regularly lubricated with a grease gun.
• Storage: When not in use, clean the guide bar and chain, apply a light coat of oil to prevent rust, and store them in a dry place.

Troubleshooting

Here are some common issues and their potential solutions:

• Chain Cuts Crooked: This often indicates uneven sharpening of the cutters or uneven wear on the guide bar rails. Re-sharpen the chain carefully, ensuring all cutters are the same length and angle. Inspect and file the guide bar rails if necessary.
• Chain Dull Quickly: Could be due to cutting dirty wood, hitting foreign objects, or improper sharpening angles. Ensure the chain is sharpened correctly and avoid contact with soil or rocks.
• Chain Not Oiling: Check the chainsaw's oil tank level, ensure the oiler is functioning, and clean the guide bar oil holes and groove.
• Chain Jumps Off Bar: Incorrect chain tension (too loose) or worn guide bar rails can cause this. Adjust tension or replace worn components.
