4. Installation

Refer to your chainsaw's owner's manual for specific chain installation instructions. General steps typically include:

1. Ensure the chainsaw is turned off and the spark plug wire is disconnected to prevent accidental starting.
2. Remove the clutch cover and old chain (if applicable).
3. Carefully place the new Oregon L81 chain onto the guide bar, ensuring the cutting edges face the correct direction (usually forward on the top of the bar).
4. Fit the chain around the drive sprocket.
5. Reinstall the clutch cover, leaving the nuts slightly loose.
6. Adjust chain tension according to your chainsaw's manual. The chain should be snug but still able to be pulled freely around the bar by hand.
7. Tighten the clutch cover nuts securely.

5. Operation

Once the Oregon L81 ControlCut chain is correctly installed and tensioned, you can begin operation. The Micro Chisel cutters are designed for efficient cutting, especially in hardwood. The low-kickback design contributes to a smoother and safer cutting experience.

Always maintain a firm grip on the chainsaw and stand in a balanced position. Allow the chain to do the work; do not force it through the wood. Be aware of your surroundings and potential hazards. The integrated Lubri-Tec system will automatically oil the chain during operation, but regular checks of your chainsaw's oil reservoir are still necessary.

6. Maintenance

Proper maintenance extends the life of your Oregon L81 ControlCut chain and ensures consistent cutting performance.

Chain Lubrication:

The built-in Lubri-Tec automatic oiling system is designed to deliver oil to key parts of the chain and guide bar. Regularly check your chainsaw's oil level and refill with appropriate bar and chain oil to ensure continuous lubrication.

Sharpening:

The Micro Chisel cutters are designed for easy maintenance and sharpening. When the chain becomes dull, it will cut less efficiently and produce fine sawdust instead of chips. Sharpen the chain regularly using a round file of the correct diameter (refer to your chainsaw manual or chain specifications for the exact size). Maintain the correct filing angles for optimal performance.

Cleaning and Storage:

After each use, clean the chain to remove sawdust, sap, and debris. A clean chain reduces wear and prevents corrosion. Store the chain in a dry environment to prevent rust. If storing for an extended period, lightly oil the chain before storage.

7. Troubleshooting Common Issues

• Chain Not Cutting Efficiently: Check if the chain is dull and requires sharpening. Ensure the chain is installed with the cutters facing the correct direction. Verify proper chain tension.
• Excessive Vibration: This can indicate improper chain tension, a damaged chain, or a worn guide bar. Inspect all components and adjust or replace as necessary.
• Chain Smoking or Overheating: Insufficient lubrication is a common cause. Check the chainsaw's oil reservoir and ensure the Lubri-Tec system is functioning. Also, verify chain tension is not too tight.
• Chain Derailment: Incorrect chain tension (too loose) or a worn guide bar can cause the chain to come off. Adjust tension or inspect the guide bar for wear.
