1. Master the Art of Chain Filing: The Heart of Chain Performance

Filing your chain correctly is arguably the most critical factor in maintaining its performance. A dull chain not only slows you down but also puts undue stress on your chainsaw’s engine and increases the risk of kickback. I’ve seen firsthand how a well-filed chain can transform a struggling saw into a wood-eating machine.

Think of it this way: a sharp chain is like a razor-sharp knife slicing through butter, while a dull chain is like trying to cut with a spoon. The difference in effort, efficiency, and safety is substantial.

Why Filing Matters: Data-Backed Benefits

According to a study by the Forest Engineering Research Institute of Canada (FERIC), properly maintained chainsaw chains can reduce cutting time by up to 30% and fuel consumption by up to 15%. These are significant numbers that translate to real savings in time and money.

Step-by-Step Guide to Chain Filing

Here’s my tried-and-true method for filing my Poulan Pro 20 chain:

1. Secure the Chainsaw: Engage the chain brake and secure the saw in a vise or on a stable surface. This prevents movement and ensures safety.
2. Identify the Correct File Size: Consult your Poulan Pro 20’s manual for the recommended file size. Using the wrong size can damage the cutters. Typically, a 5/32″ or 3/16″ round file is appropriate.
3. Use a Filing Guide: A filing guide helps maintain the correct angle and depth, ensuring consistent sharpening. I personally prefer the Oregon 25894 Filing Guide, as it’s robust and easy to use.
4. File Each Cutter: Hold the file at the correct angle (usually marked on the filing guide) and file each cutter with smooth, even strokes, pushing the file away from you. Aim for 3-5 strokes per cutter.
5. Maintain Consistent Length: After filing several cutters, check their length. Uneven cutter lengths can cause the saw to cut crookedly. Use a depth gauge tool to ensure all cutters are uniform.
6. Lower the Depth Gauges (Rakers): Use a flat file and a depth gauge tool to lower the depth gauges (rakers) according to the manufacturer’s specifications. Too high rakers will prevent the cutters from biting into the wood.
7. Deburr the Cutters: Use a fine file or a deburring tool to remove any burrs from the cutters, ensuring a clean, sharp edge.

Expert Insight: “Always file your chain after every few tanks of fuel or whenever you notice a decrease in cutting performance,” advises seasoned logger, Hank Williams (no relation to the country music legend). “Preventative maintenance is key to extending chain life and preventing costly repairs.”

Common Filing Mistakes and How to Avoid Them

• Incorrect Filing Angle: Using the wrong angle can weaken the cutters and reduce their effectiveness. Always use a filing guide.
• Rounding the Cutters: Filing too aggressively can round the cutters, making them less sharp. Use smooth, even strokes.
• Ignoring the Depth Gauges: Neglecting the depth gauges can render even a sharp chain ineffective. Regularly check and adjust them.

Case Study: I once worked alongside a firewood producer who consistently neglected chain maintenance. His saws were constantly underperforming, leading to increased fuel consumption and longer working hours. After implementing a regular filing routine, he saw a dramatic improvement in efficiency and a significant reduction in fuel costs.

2. Master Chain Tension: The Balancing Act for Safety and Performance

Proper chain tension is crucial for both safety and performance. A chain that is too loose can derail, causing damage to the saw and potentially injuring the operator. A chain that is too tight can overheat, leading to premature wear and tear. Finding that sweet spot is essential.

The Science of Chain Tension:

Chain tension is affected by several factors, including temperature, chain type, and bar length. As the chain heats up during use, it expands, requiring adjustments to maintain proper tension.

How to Adjust Chain Tension (Poulan Pro 20 Specific)

1. Loosen the Bar Nuts: Use the wrench provided with your Poulan Pro 20 to slightly loosen the bar nuts.
2. Adjust the Tensioning Screw: Locate the chain tensioning screw (usually on the side of the saw) and turn it clockwise to tighten the chain or counterclockwise to loosen it.
3. Check the Tension: The chain should be snug against the bar but still able to be pulled around by hand. A good rule of thumb is that you should be able to pull the chain about ¼ inch away from the bar in the middle.
4. Tighten the Bar Nuts: Once you’ve achieved the correct tension, tighten the bar nuts securely.
5. Recheck After a Few Cuts: After making a few cuts, recheck the chain tension, as it may loosen slightly as the chain settles in.

Data Point: According to a study by the National Institute for Occupational Safety and Health (NIOSH), improper chain tension is a contributing factor in approximately 15% of chainsaw-related injuries. This highlights the importance of paying close attention to this crucial aspect of chainsaw maintenance.

Troubleshooting Common Tension Issues

• Chain is Too Loose: Tighten the tensioning screw until the chain is snug against the bar.
• Chain is Too Tight: Loosen the tensioning screw until the chain can be pulled around by hand.
• Chain Keeps Loosening: Check for wear on the bar and chain. A worn bar or chain may need to be replaced.

Personal Story: I once experienced a chain derailment while cutting firewood due to improper tension. The chain snapped back and narrowly missed my leg. That incident served as a stark reminder of the importance of paying close attention to chain tension and safety procedures.

3. Choosing the Right Chain: Not All Chains Are Created Equal

The Poulan Pro 20 is a versatile saw, but its performance can be significantly impacted by the type of chain you use. Different chains are designed for different applications, from aggressive ripping to clean cross-cutting. Choosing the right chain for the job can improve efficiency, reduce wear and tear, and enhance safety.
