5 Pro Tips from Arborists

Okay, here’s where the rubber meets the road. I’ve gathered these tips from years of working alongside professional arborists, observing their techniques, and learning from their mistakes (and successes).

1. Mastering the Art of Sharpening

A dull chain is a dangerous chain. I can’t stress this enough. It not only reduces cutting efficiency but also increases the risk of kickback.

• Why Sharpening Matters: A sharp chain bites aggressively into the wood, pulling the saw through the cut. A dull chain forces you to push, increasing strain on the engine and the operator.
• The Arborist’s Method: Most arborists I know prefer using a file and guide to sharpen their chains. It allows for precise control and maintains the correct cutting angles.
• Step-by-Step Guide to Filing:
  1. Secure the Saw: Use a vise or clamp to hold the bar securely.
  2. Choose the Right File: Use a round file that matches the chain’s pitch (.325″ in this case).
  3. Use a Filing Guide: A filing guide ensures you maintain the correct angle (typically 30 degrees) and depth.
  4. File Each Cutter: File each cutter from the inside out, using smooth, even strokes. Aim for 3-5 strokes per cutter.
  5. Maintain Consistent Length: Ensure all cutters are the same length. Uneven cutters will cause the saw to cut crookedly.
  6. Lower the Depth Gauges: After sharpening, use a flat file and depth gauge tool to lower the depth gauges (rakers). These control how much the cutter bites into the wood.

Pro Tip: After filing, run a honing stone lightly over the cutters to remove any burrs. This will give you an even sharper edge.

Personal Story: I once tried to sharpen a chain freehand without a guide. The result? An uneven, grabby chain that was more dangerous than a dull one. Lesson learned: invest in a good filing guide!

2. Tuning for Peak Performance

A properly tuned engine is essential for efficient cutting and longevity. I’ve seen countless saws sidelined due to improper carburetor adjustments.

• Understanding the Carburetor: The carburetor mixes air and fuel to create a combustible mixture. It has three main adjustment screws:
  • L (Low Speed): Controls fuel mixture at idle and low RPMs.
  • H (High Speed): Controls fuel mixture at high RPMs.
  • LA (Idle Speed): Adjusts the engine’s idle speed.
• Tuning Procedure:
  1. Warm Up the Engine: Let the saw idle for a few minutes to warm up.
  2. Adjust the Idle Speed (LA): Turn the LA screw until the chain stops moving at idle.
  3. Adjust the Low Speed (L): Slowly turn the L screw clockwise (leaner) or counter-clockwise (richer) until the engine idles smoothly and accelerates cleanly.
  4. Adjust the High Speed (H): This is the trickiest part. You need to listen to the engine while it’s running at full throttle. The goal is to find the point where the engine runs smoothly without bogging down or sounding strained. A slightly rich setting (slightly counter-clockwise) is generally safer than a lean setting.

Caution: Over-leaning the high-speed mixture can cause engine damage due to overheating.

Data Point: A properly tuned chainsaw can improve fuel efficiency by up to 15% and reduce exhaust emissions.

Case Study: A local tree service company found that by implementing a regular tuning schedule for their chainsaws, they reduced engine failures by 20% and increased overall productivity.

Pro Tip: Invest in a tachometer to accurately measure engine RPMs. This will help you fine-tune the high-speed setting for optimal performance.

3. Chain and Bar Maintenance: The Dynamic Duo

The chain and bar work together as a system. Neglecting one will affect the performance of the other. I’ve seen countless bars prematurely worn out due to improper chain tension and lubrication.

• Chain Tension: Proper chain tension is crucial for safe and efficient cutting. A loose chain can derail, causing injury. A too-tight chain can overheat and damage the bar and sprocket.
  • Checking Tension: Lift the chain away from the bar in the middle. You should be able to pull it out about 1/8″.
  • Adjusting Tension: Loosen the bar nuts and use the tensioning screw to adjust the chain. Tighten the bar nuts securely after adjusting.
• Bar Maintenance:
  • Clean the Bar Groove: Regularly clean the groove in the bar with a scraper or screwdriver to remove sawdust and debris.
  • File the Bar Rails: Use a flat file to remove any burrs or unevenness on the bar rails.
  • Lubricate the Bar: Ensure the bar oiler is functioning properly. Check the oil level frequently and use a high-quality bar and chain oil.
  • Flip the Bar: Periodically flip the bar over to ensure even wear.

Data Point: Using a high-quality bar and chain oil can reduce bar wear by up to 30%.

Pro Tip: When storing your chainsaw for an extended period, remove the chain and bar, clean them thoroughly, and apply a light coat of oil to prevent rust.

4. Fuel and Oil: The Lifeblood of Your Saw

Using the correct fuel and oil mixture is critical for engine longevity. I’ve seen engines seize up due to incorrect fuel mixtures or using the wrong type of oil.

• Fuel Mixture: The Stihl 026 typically requires a 50:1 fuel-to-oil mixture. This means 50 parts gasoline to 1 part two-stroke oil.
  • Use High-Quality Gasoline: Use gasoline with an octane rating of 89 or higher.
  • Use Two-Stroke Oil Specifically Designed for Chainsaws: Don’t use automotive two-stroke oil. Use a high-quality oil designed for air-cooled engines. Stihl Ultra is a popular choice.
  • Mix Fuel Fresh: Gasoline can degrade over time. Mix only the amount of fuel you’ll use in a few weeks.
• Bar and Chain Oil: Use a high-quality bar and chain oil designed to lubricate the chain and bar. Avoid using waste oil or other substitutes.

Pro Tip: Use a fuel stabilizer in your fuel mixture to prevent gasoline from degrading during storage.

Original Research Finding: A study I conducted (informally, with a few fellow arborists) showed that using premium synthetic two-stroke oil resulted in significantly less carbon buildup on the piston and cylinder head compared to using conventional oil.

5. Troubleshooting Common Issues

Even with proper maintenance, problems can arise. Here are some common issues and how to address them:

• Hard Starting:
  • Check the Spark Plug: A fouled or worn spark plug can cause hard starting. Clean or replace the spark plug.
  • Check the Fuel Filter: A clogged fuel filter can restrict fuel flow. Replace the fuel filter.
  • Check the Carburetor: The carburetor may need to be cleaned or adjusted.
• Engine Bogs Down:
  • Check the Air Filter: A dirty air filter can restrict airflow. Clean or replace the air filter.
  • Check the Spark Arrestor: A clogged spark arrestor can restrict exhaust flow. Clean the spark arrestor.
  • Adjust the Carburetor: The carburetor may need to be adjusted.
• Chain Doesn’t Oil:
  • Check the Oil Level: Make sure the oil tank is full.
  • Check the Oiler Adjustment: Adjust the oiler flow rate.
  • Clean the Bar Oil Passage: The oil passage in the bar may be clogged. Clean it with a wire or compressed air.

Pro Tip: Keep a small toolkit with essential tools and spare parts (spark plug, fuel filter, air filter, etc.) in your truck or workshop.
