1. Product Overview
The Oregon 20LGX100U PowerCut Saw Chain reel contains 100’ of 20LGX chain, designed for experienced professional loggers and tree care workers using .325" saws. This .050" gauge saw chain features low-vibration, full chisel cutters that ensure quick and precise cutting. The depth gauges are engineered to provide maximum chain performance and a smooth cutting experience on higher output, .325" pitch chainsaws. This chain reel is compatible with the Stihl 23RS 100' Reel.

2. Key Features
- Pitch: .325", Gauge: .050", Cutter Type: Full Chisel. These specifications ensure optimal cutting performance for compatible chainsaws.
- LubriTec: This advanced lubrication system keeps your chain and guide bar consistently oiled, reducing friction and extending the lifespan of both components.
- Blued Cutters: The cutters are treated with a blued finish, providing high-quality protection against corrosion and enhancing durability.
- Top-Plate Filing Indicators: Integrated indicators on the top plate simplify the sharpening process, making it easier to achieve accurate and consistent sharpening angles.
- Exclusive OCS-01 Steel: Constructed from Oregon's exclusive OCS-01 steel, this chain offers superior durability and resilience, suitable for saw sizes ranging from 38-62 cc.

3. Installation (Setup)
Proper installation of your new Oregon PowerCut chain is crucial for safety and performance. Always refer to your chainsaw's specific owner's manual for detailed instructions on chain replacement, as procedures may vary between models.
- Safety First: Ensure the chainsaw is turned off, the spark plug cap is disconnected (for gas saws), or the battery is removed (for electric saws) to prevent accidental starting. Wear appropriate safety gloves.
- Remove Old Chain: Loosen the bar nuts and remove the clutch cover. Carefully lift the old chain and guide bar from the saw. Inspect the guide bar for wear, burrs, or damage, and clean any sawdust or debris.
- Inspect Sprocket: Check the drive sprocket for wear. A worn sprocket can damage a new chain and lead to poor performance. Replace if necessary.
- Install New Chain: Place the new Oregon PowerCut chain onto the drive sprocket, ensuring the cutters are facing the correct direction (usually indicated by an arrow on the chain or guide bar).
- Mount Guide Bar: Fit the guide bar over the chain and the bar studs. Ensure the chain fits correctly into the guide bar groove.
- Replace Clutch Cover: Reinstall the clutch cover and hand-tighten the bar nuts.
- Adjust Chain Tension: Adjust the chain tension according to your chainsaw's manual. The chain should be snug against the bottom of the guide bar, but still able to be pulled around the bar by hand. It should not sag underneath the bar.
- Final Check: Once tensioned, fully tighten the bar nuts. Reconnect the spark plug cap or insert the battery. Before cutting, run the saw briefly at half throttle to ensure proper lubrication and chain seating.
4. Operating Guidelines
While this manual focuses on the chain, proper chainsaw operation is essential for safety and efficiency. Always follow the operating instructions provided with your chainsaw.
- Chain Lubrication: Ensure the chainsaw's oil reservoir is filled with appropriate bar and chain oil. The LubriTec feature of your Oregon chain relies on a consistent oil supply.
- Maintain Proper Tension: Regularly check and adjust chain tension. A loose chain can derail, and a too-tight chain can cause excessive wear to the chain, bar, and sprocket, and reduce power.
- Sharpness: Always operate with a sharp chain. A dull chain forces the saw to work harder, leading to slower cutting, increased fuel consumption, and potential kickback.
- Cutting Technique: Use proper cutting techniques to avoid kickback and ensure smooth cuts. Do not force the saw; let the sharp chain do the work.
5. Maintenance
Regular maintenance extends the life of your Oregon PowerCut chain and ensures safe, efficient operation.
5.1. Sharpening
The 20LGX chain features Top-Plate Filing Indicators to assist with accurate sharpening. Use a round file of the correct diameter (.325" pitch typically uses a 3/16" or 4.8mm file) and a filing guide for best results. Sharpen each cutter to the same length and angle, maintaining the original top plate and side plate angles.
5.2. Lubrication
The LubriTec system on your chain is designed to optimize oil delivery. Always use high-quality bar and chain oil. Ensure your chainsaw's automatic oiler is functioning correctly and that the oil tank is kept full during operation.
5.3. Cleaning and Inspection
After each use, clean sawdust, sap, and debris from the chain and guide bar. Inspect the chain for any damaged or missing links, cracks, or excessive wear. Check the depth gauges and file them down if they are too high, as this can affect cutting performance.
6. Troubleshooting Common Issues
| Issue | Possible Cause | Solution |
|---|---|---|
| Chain not cutting efficiently / Dull cutting | Dull cutters, incorrect sharpening angle, depth gauges too high. | Sharpen chain using correct file and angles. Check and adjust depth gauges. |
| Chain smoking or overheating | Lack of lubrication, incorrect chain tension (too tight), dull chain. | Check oil reservoir and oiler function. Adjust chain tension. Sharpen chain. |
| Chain coming off guide bar | Loose chain tension, worn guide bar groove, worn drive sprocket. | Adjust chain tension. Inspect and replace guide bar or sprocket if worn. |
| Excessive vibration | Damaged or bent chain links, incorrect chain tension. | Inspect chain for damage; replace if necessary. Adjust chain tension. |
