4. Setup (Chain Installation)
Follow these steps to safely install or replace your chainsaw chain. Refer to your chainsaw's specific manual for detailed instructions on removing covers and adjusting tensioners.
インストール手順:
- 安全の確保: Disconnect the chainsaw from its power source (remove battery or unplug from outlet). Engage the chain brake.
- バーカバーを取り外す: Loosen the bar nuts and remove the side cover that secures the guide bar and chain.
- 古いチェーンを削除する: Carefully remove the old chain from the guide bar and drive sprocket. Inspect the guide bar for wear, burrs, or damage, and clean the guide bar groove and sprocket area.
- 新しいチェーンの取り付け: Place the new Oregon AdvanceCut R33 chain onto the drive sprocket. Ensure the cutting edges of the chain cutters are facing the correct direction (usually forward, away from the chainsaw body, on the top of the guide bar).
- Fit Chain to Guide Bar: Guide the chain into the groove around the entire guide bar.
- バーカバーを再度取り付けます。 Position the guide bar onto the mounting studs and replace the side cover. Hand-tighten the bar nuts, but do not fully tighten them yet.
- チェーンの張力を調整する: Using the chain tensioning screw (refer to your chainsaw manual), adjust the chain tension. The chain should be snug against the guide bar, but still able to be pulled freely by hand. There should be no slack on the underside of the bar, and the drive links should not come out of the bar groove.
- 最終締め付け: ガイドバーの先端を上に持ち上げながら、バーナットを完全に締め付けます。締め付け後、チェーンの張りを再度確認してください。
- テスト操作: Briefly run the chainsaw at low speed to ensure the chain runs smoothly and the tension remains correct. Adjust if necessary.

5. 操作手順
Once the Oregon AdvanceCut R33 chain is correctly installed and tensioned, ensure you are familiar with your chainsaw's operating procedures. Always maintain a firm grip with both hands, stand in a balanced position, and keep the chain sharp for optimal cutting performance and safety. Avoid cutting into dirt or foreign objects, as this will dull the chain quickly.
6. メンテナンス
Regular maintenance is crucial for the longevity and performance of your Oregon AdvanceCut R33 chainsaw chain.
チェーン研磨:
The R33 chain features top-plate filing indicators to guide accurate sharpening. Use a round file of the correct diameter (typically 5/32 inch or 4.0 mm for .043" gauge, 3/8" LP pitch chains, but always verify with your chainsaw manual or Oregon's specifications). Maintain the correct filing angle and depth gauge setting for optimal cutting. Sharpen cutters evenly to ensure balanced cutting.
潤滑:
The LubriTec oiling system is designed to keep the chain and guide bar continuously lubricated during operation. Regularly check your chainsaw's oil reservoir and refill with quality bar and chain oil as needed. Proper lubrication prevents excessive wear and heat buildup.
クリーニング：
Periodically clean the guide bar groove to remove sawdust and debris that can impede chain movement and oil flow. Also, clean the sprocket area and the inside of the side cover.
