4. Setup and Installation

Before installing the new chain, ensure your chainsaw is turned off and the spark plug wire is disconnected to prevent accidental starting. Always wear appropriate safety gear, including heavy-duty gloves.

4.1 Verifying Chain Compatibility

It is crucial to ensure the replacement chain matches the correct pitch, gauge, and drive link count for your chainsaw's guide bar. All chainsaw chains are a "called length," and the replacement chain will fit when these three specifications are correct.

Figure 4.1: Diagram illustrating how to measure a chainsaw bar, chain pitch, gauge, and drive links. This visual guide helps in confirming the correct chain specifications for your chainsaw.

• Chain Pitch: Measure the distance between any three consecutive rivets and divide by two.
• Chain Gauge: This is the thickness of the drive link, where it fits into the guide-bar groove.
• Bar Length (Called Length or Cutting Length): Measure the distance from the front of the saw to the tip of the farthest cutter, rounded to the nearest inch.
• Drive Links: Count the number of drive links on your existing chain. This chain has 76 drive links.

4.2 Chain Installation Steps

1. Prepare the Chainsaw: Ensure the chainsaw is off, cool, and the spark plug wire is disconnected. Engage the chain brake.
2. Remove Bar Cover: Loosen the bar nuts and remove the side cover that holds the guide bar in place.
3. Remove Old Chain: Carefully remove the old chain from the guide bar and sprocket.
4. Clean Components: Clean any sawdust or debris from the guide bar groove, sprocket, and chain brake area.
5. Install New Chain: Place the new Archer chain onto the sprocket, ensuring the cutting edges are facing the correct direction (usually forward on the top of the bar).
6. Fit Chain to Bar: Guide the drive links into the groove of the guide bar.
7. Reattach Bar Cover: Position the guide bar onto the studs and replace the side cover. Hand-tighten the bar nuts.
8. Adjust Chain Tension: Using the tensioning screw (usually located on the side cover), adjust the chain tension. The chain should be snug against the guide bar but still able to be pulled freely by hand. It should not sag on the underside of the bar.
9. Tighten Bar Nuts: Once tension is correct, fully tighten the bar nuts.
10. Reconnect Spark Plug: Reconnect the spark plug wire.

5. Operating Guidelines

While this manual focuses on the chain, proper operation of the chainsaw itself is critical for safety and chain longevity. Always refer to your chainsaw's specific instruction manual for detailed operating procedures.

• Lubrication: Ensure the chainsaw's oil reservoir is filled with appropriate bar and chain oil. Proper lubrication is vital for reducing friction and heat, extending chain life.
• Chain Tension Check: Regularly check chain tension during operation. A loose chain can derail, and an overly tight chain can cause premature wear to the chain, bar, and sprocket.
• Cutting Technique: Use proper cutting techniques to avoid kickback and unnecessary strain on the chain.
• Avoid Contaminants: Do not cut into dirt, rocks, or metal, as this will dull the chain quickly and can cause damage.

6. Maintenance

Regular maintenance of your Archer chainsaw chain will ensure its performance and extend its lifespan.

• Sharpening: Sharpen the chain regularly with the correct file size and angle. A sharp chain cuts efficiently and safely. This full chisel chain requires precise sharpening.
• Cleaning: After each use, clean the chain to remove sap, sawdust, and debris. A clean chain operates more smoothly.
• Lubrication: Ensure consistent oil flow to the chain during operation. Check the oiler port for blockages.
• Storage: When not in use, store the chain in a clean, dry place. Applying a light coat of oil can prevent rust.
• Inspect for Damage: Periodically inspect the chain for bent or broken drive links, cracked cutters, or other damage. Replace damaged chains immediately.
