1. Introduction
This manual provides essential instructions for the safe and effective use of your Oregon 91P056E chainsaw chain. This 16-inch (40 cm) low-kickback chain features 56 drive links and is designed for various chainsaw models, including those from Husqvarna, McCulloch, and Black & Decker. The chain is engineered with special shaped low-vibration heels and ramp-shaped depth gauges to reduce kickback while maintaining cutting performance and durability.
2. Safety Information
Always prioritize safety when working with chainsaws and chainsaw chains. Failure to follow safety guidelines can result in serious injury.
- Read Your Chainsaw Manual: Always consult your chainsaw's instruction manual for specific safety procedures, installation, and operation guidelines.
- Wear Protective Gear: Always wear appropriate personal protective equipment (PPE), including safety glasses, hearing protection, gloves, and protective legwear.
- Understand Kickback: This Oregon chain is designed with low-kickback features. However, kickback can still occur. Be aware of potential kickback zones and maintain a firm grip on the chainsaw.
- Inspect Before Use: Before each use, inspect the chain for damage, dullness, or loose components. Never operate a chainsaw with a damaged or improperly installed chain.
- Proper Tension: Ensure the chain is correctly tensioned according to your chainsaw manufacturer's specifications. An improperly tensioned chain can derail or cause injury.

3. Setup and Installation
Installing your new Oregon chainsaw chain correctly is crucial for safety and performance. Refer to your chainsaw's owner's manual for detailed, model-specific instructions.
- Prepare Chainsaw: Ensure the chainsaw is turned off, unplugged (electric), or the spark plug wire is disconnected (gasoline) to prevent accidental starting. Engage the chain brake.
- Remove Old Chain: Loosen the bar nuts and remove the clutch cover. Carefully remove the old chain and guide bar.
- Clean Components: Clean any sawdust or debris from the guide bar groove, sprocket, and clutch area.
- Install New Chain: Place the new Oregon chain onto the sprocket, ensuring the cutting edges are facing the correct direction (usually forward on the top of the guide bar). Fit the chain into the guide bar groove.
- Reattach Guide Bar and Cover: Slide the guide bar back into position, ensuring the chain tensioner pin engages with the hole in the bar. Replace 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 guide bar but still able to be pulled freely by hand. It should not sag underneath the bar.
- Tighten Bar Nuts: Once tension is set, fully tighten the bar nuts.

4. Operating Instructions
While this manual focuses on the chain, proper chainsaw operation is essential for chain longevity and user safety. Always refer to your chainsaw's manual for complete operating instructions.
- Lubrication: Ensure your chainsaw's oil reservoir is filled with appropriate bar and chain oil. Proper lubrication is vital to reduce friction, heat, and wear on the chain and guide bar.
- Cutting Technique: Use proper cutting techniques to avoid binding, pinching, or kickback. Let the chain do the work; do not force it.
- Avoid Ground Contact: Do not allow the chain to contact the ground, rocks, or other hard objects, as this will dull the chain quickly and can cause damage.
- Monitor Chain Condition: Periodically check the chain during operation for dullness or damage. A dull chain requires more force, increases wear, and can be dangerous.
5. Maintenance
Regular maintenance extends the life of your Oregon chainsaw chain and ensures safe, efficient cutting.
- Sharpening: Sharpen the chain regularly. The Oregon 91P056E chain typically requires a 5/32" (4.0 mm) round file and a sharpening angle of 30 degrees. Maintain consistent angles and depth gauge settings for optimal performance.
- Cleaning: After each use, clean the chain to remove sap, sawdust, and debris. A clean chain operates more smoothly and reduces wear.
- Lubrication: Ensure continuous and adequate lubrication during operation. Check the oiler function regularly.
- Inspection: Inspect the chain for stretched links, cracks, broken rivets, or other damage. Replace the chain if any significant damage is found.
- Guide Bar Maintenance: Flip the guide bar periodically to ensure even wear. Clean the guide bar groove and oil holes.

6. Troubleshooting
Here are some common issues and their potential solutions related to your chainsaw chain:
| Problem | Possible Cause | Solution |
|---|---|---|
| Chain not cutting efficiently | Dull cutters, incorrect sharpening angle, improper depth gauge setting | Sharpen chain, ensure correct file size and angle, adjust depth gauges |
| Chain smoking or overheating | Insufficient lubrication, dull chain, incorrect chain tension | Check bar oil level and oiler function, sharpen chain, adjust chain tension |
| Chain derails from guide bar | Loose chain tension, worn guide bar, damaged drive links | Adjust chain tension, inspect and replace guide bar if worn, replace damaged chain |
| Excessive vibration | Damaged chain, unevenly sharpened cutters, worn sprocket | Inspect and replace chain if damaged, ensure even sharpening, check and replace sprocket if worn |
