Installation Steps (General):

1. Safety First: Ensure the chainsaw is turned off, spark plug cap is removed (for gas saws), or battery is disconnected (for electric saws) before handling the chain. Wear appropriate protective gloves.
2. Remove Old Chain: Loosen the bar nuts and remove the clutch cover. Carefully remove the old chain and guide bar.
3. Clean: Clean any sawdust or debris from the guide bar groove, sprocket, and clutch area.
4. Install New Chain: Place the new Oregon 72JGX072G chain onto the sprocket, ensuring the cutters are facing the correct direction (usually clockwise when viewed from the side). Fit the drive links into the guide bar groove.
5. Reattach Bar and Cover: Slide the guide bar back into position and reattach the clutch cover, hand-tightening the bar nuts.
6. Tension the Chain: Adjust the chain tension according to your chainsaw's manual. The chain should be snug against the bottom of the bar, but still able to be pulled around the bar by hand. It should not sag underneath the bar.
7. Tighten Bar Nuts: Fully tighten the bar nuts.
8. Check Tension: Re-check chain tension after the first few cuts, as new chains can stretch slightly.

Operating Guidelines

The Oregon 72JGX072G Power Cut Saw Chain is designed for efficient cutting. Adhere to these guidelines for optimal performance and safety.

• Proper Lubrication: Ensure your chainsaw's oiler is functioning correctly and the bar and chain are adequately lubricated during operation. This reduces friction and heat, extending chain life.
• Cutting Technique: Allow the chain to do the work. Do not force the saw through wood. Apply steady, consistent pressure.
• Chip Flow: The 72JGX chain features a Skip Sequence Design which provides greater clearance for better chip flow. This is particularly important when cutting larger wood or using longer guide bars, as it prevents sawdust buildup and maintains cutting efficiency.
• Avoid Dirty Wood: Do not cut into dirt, rocks, or metal, as this will rapidly dull or damage the chain.
• Kickback Awareness: While this chain features low-vibration cutters, always be aware of potential kickback. Maintain a firm grip on the saw and stand in a balanced position.

Maintenance

Regular maintenance is essential for the longevity and performance of your Oregon saw chain.

Sharpening:

A sharp chain cuts efficiently and safely. Dull chains can cause excessive vibration, poor cutting performance, and increased wear on the chainsaw. Sharpen the chain regularly using the appropriate file size and angle for a 3/8" pitch, full chisel chain. Consult a professional if unsure.

Cleaning:

After each use, clean the chain to remove sap, resin, and sawdust. A wire brush and chain cleaner can be used. Ensure the chain is dry before storage.

Lubrication and Corrosion Protection:

The 72JGX chain features Blued Cutters which deliver high-quality protection against corrosion. However, for extended storage, apply a light coat of bar and chain oil to prevent rust.

Storage:

Store the chain in a clean, dry place, away from moisture and direct sunlight. Keep it in its original packaging or a protective case to prevent damage to the cutters.

Troubleshooting

Here are some common issues and their potential solutions:

• Chain Not Cutting Efficiently:
  • Check if the chain is dull. Sharpen or replace if necessary.
  • Verify chain tension. Too loose or too tight can affect cutting.
  • Ensure proper lubrication from the chainsaw's oiler.
• Excessive Vibration:
  • Chain may be dull or damaged. Inspect cutters for damage.
  • Chain tension might be incorrect.
  • Guide bar groove may be worn or dirty.
• Sawdust Buildup / Poor Chip Flow:
  • Ensure the guide bar groove is clean.
  • Check if the chain is dull, as dull cutters produce fine dust instead of chips.
  • Verify the chain's "Skip Sequence Design" is not obstructed by debris.
• Chain Derails from Bar:
  • Chain tension is too loose.
  • Guide bar is worn or damaged.
  • Drive links are damaged.
