36 Inch Bar Chainsaw Guide (5 Expert Tips For Longer Bars)

36-Inch Bar Chainsaw Guide: 5 Expert Tips for Longer Bars

Understanding the Beast: The 36-Inch Chainsaw Advantage

The 36-inch bar chainsaw is a serious tool. It’s not your average homeowner’s saw. It’s designed for tackling large-diameter trees, milling lumber, and handling demanding wood processing tasks. It offers increased reach and cutting capacity, allowing you to fell larger trees with fewer cuts and mill wider boards. However, this power comes with increased weight, complexity, and the potential for kickback.

From my experience, choosing to use a 36-inch bar chainsaw is a trade-off. I remember a project years ago where I was tasked with felling some old-growth Douglas fir. The trees were massive, with diameters exceeding 4 feet. Without a 36-inch bar saw, the job would have been significantly more time-consuming and dangerous, requiring multiple cuts and increasing the risk of barber chairing (when a tree splits upward during the felling process). In that instance, the 36-inch bar was the right tool for the job.

But it’s crucial to understand the risks. A longer bar means a larger cutting surface, increasing the potential for kickback. It also means more weight, which can lead to fatigue and reduced control. That’s why proper training, maintenance, and technique are essential when working with these powerful saws.

Tip #1: Mastering Chain Tension: The Key to Bar Longevity

Maintaining proper chain tension is paramount for any chainsaw, but it’s especially critical for those with longer bars. A loose chain will whip and vibrate, causing excessive wear on the bar, chain, and sprocket. A chain that’s too tight will bind, generating heat and potentially damaging the saw’s engine.

The Right Way to Tension:

Frequency: Check chain tension before each use and every time you refuel.
Procedure: With the engine off and the saw on a stable surface, loosen the bar nuts slightly. Use the chain tensioning screw to adjust the chain until the drive links just barely touch the bottom of the bar rail. You should be able to pull the chain freely around the bar by hand but without excessive slack.
The “Pull-Away” Test: A good rule of thumb is that you should be able to pull the chain away from the bar about the width of a dime.
Hot vs. Cold: Remember that the chain will expand as it heats up during use. It’s better to err on the side of slightly loose tension when the chain is cold.
Data Point: According to Oregon Products, a leading manufacturer of chainsaw chains and bars, maintaining proper chain tension can extend bar life by up to 50%.

Why it Matters: Proper tension reduces friction and heat, preventing premature wear and tear on the bar. It also ensures the chain cuts efficiently, reducing strain on the engine and improving fuel economy.

Tip #2: Oil is Life: Lubrication Strategies for Longer Bars

Adequate lubrication is the lifeblood of any chainsaw, but it’s even more critical for longer bars. The longer the bar, the more surface area needs to be lubricated, and the greater the potential for friction and heat buildup. Insufficient lubrication will lead to premature wear on the bar, chain, and sprocket, and can even cause the chain to seize up.

My Personal Experience: I’ve seen firsthand the devastating effects of poor lubrication. A colleague of mine, who was notoriously stingy with bar oil, had a 36-inch bar saw fail catastrophically during a felling operation. The bar seized up so violently that it snapped in half, sending the chain flying. Fortunately, no one was injured, but it was a stark reminder of the importance of proper lubrication.

Effective Lubrication Practices:

Use the Right Oil: Always use a high-quality bar and chain oil specifically designed for chainsaws. Avoid using motor oil or other substitutes, as they may not provide adequate lubrication and can damage the saw.
Check Oil Levels Frequently: Check the oil reservoir before each use and refill as needed. Don’t wait until the reservoir is empty.
Adjust the Oiler: Most chainsaws have an adjustable oiler that allows you to control the amount of oil delivered to the bar and chain. Adjust the oiler to ensure adequate lubrication, especially when cutting hard or dry wood.
Monitor Oil Output: Check the oil output by holding the saw over a piece of cardboard or wood. You should see a steady stream of oil coming from the bar.
Consider a Bar Oiler Attachment: For extended use or particularly demanding cutting conditions, consider using a bar oiler attachment. These devices provide additional lubrication directly to the bar, ensuring adequate oil flow even when the saw is working hard.
Data Point: Stihl, another leading chainsaw manufacturer, recommends using their BioPlus chain oil, which is biodegradable and provides excellent lubrication. They claim that using their oil can reduce bar wear by up to 20%.

Optimizing Oiling for Different Woods:

Softwoods (Pine, Fir): Generally require less oil. Reduce oiler setting slightly to avoid excessive oil consumption.
Hardwoods (Oak, Maple): Require more oil due to their density and increased friction. Increase oiler setting accordingly.
Resinous Woods (Pine, Cedar): Tend to clog the oiler. Clean the oiler frequently and use a bar oil with a detergent additive.

Tip #3: Sharpening Skills: Maintaining a Razor-Sharp Chain

A sharp chain is not only essential for efficient cutting but also for the health of your bar. A dull chain requires more force to cut, which puts extra strain on the bar, engine, and your body. A sharp chain pulls itself through the wood, reducing friction and heat.

My Personal Experience: I used to dread sharpening my chainsaw chain. I found it tedious and time-consuming. But after years of experience, I’ve come to appreciate the importance of a sharp chain. I’ve also learned that with the right tools and techniques, sharpening can be a quick and easy process.

Sharpening Techniques:

Use the Right Tools: Invest in a good quality chainsaw file, a depth gauge tool, and a chain vise.
Maintain the Correct Angle: Use a file guide to maintain the correct sharpening angle for your chain. The correct angle is typically marked on the chain or in the owner’s manual.
File Each Cutter Evenly: File each cutter the same number of strokes to ensure they are all the same length.
Lower the Depth Gauges: Use a depth gauge tool to lower the depth gauges (rakers) to the correct height. The depth gauges control the amount of wood each cutter takes.
Check for Damage: Inspect the chain for any signs of damage, such as cracks or broken cutters. Replace the chain if necessary.
Frequency: Sharpen the chain every time you refuel or whenever you notice a decrease in cutting performance.
Data Point: Oregon Products estimates that a sharp chain can increase cutting speed by up to 30% and reduce fuel consumption by up to 20%.

Beyond Filing: Advanced Sharpening Methods:

Chainsaw Grinder: For high-volume sharpening or heavily damaged chains, a chainsaw grinder is a worthwhile investment. It provides precise and consistent sharpening, saving time and effort.
Professional Sharpening: If you’re not comfortable sharpening your own chain, consider taking it to a professional. They have the tools and expertise to sharpen your chain quickly and accurately.

Tip #4: Bar Maintenance: Cleaning, Dressing, and Avoiding Pinching

Proper bar maintenance is crucial for extending the life of your 36-inch bar. This includes regular cleaning, dressing the bar rails, and avoiding situations that can lead to pinching.

My Personal Experience: I once neglected to clean the bar on my chainsaw after cutting some particularly sappy pine. The sap hardened and clogged the oiler holes, leading to insufficient lubrication. The resulting friction caused the bar rails to wear unevenly, making it difficult to maintain a straight cut. I had to spend hours carefully filing the bar rails to restore them to their original condition.

Bar Maintenance Best Practices:

Cleaning: Clean the bar regularly with a wire brush to remove sawdust, sap, and debris. Pay particular attention to the oiler holes and the sprocket nose.
Dressing the Rails: Use a bar rail dresser to remove any burrs or unevenness from the bar rails. This will ensure smooth chain travel and prevent premature wear.
Rotating the Bar: Rotate the bar periodically to distribute wear evenly. This will prevent one side of the bar from wearing out faster than the other.
Avoiding Pinching: Avoid situations that can lead to pinching, such as cutting in tight spaces or felling trees with excessive lean. Use wedges or a felling lever to prevent the tree from pinching the bar during the felling process.
Checking for Wear: Regularly inspect the bar for signs of wear, such as uneven rails, a widened groove, or cracks. Replace the bar if necessary.
Data Point: According to a study by the USDA Forest Service, proper bar maintenance can extend bar life by up to 25%.

Understanding and Addressing Bar Wear:

Uneven Rail Wear: Often caused by improper chain tension or cutting with a dull chain. Can be corrected by dressing the rails.
Widened Groove: Indicates excessive wear. Requires replacement of the bar.
Bent or Warped Bar: Usually caused by pinching or overheating. Requires replacement of the bar.

Tip #5: Safe Cutting Techniques: Protecting Your Bar and Yourself

Safe cutting techniques are not only essential for preventing injuries but also for protecting your bar and chainsaw. Improper cutting techniques can put undue stress on the bar, leading to premature wear and damage.

My Personal Experience: I remember a time when I was felling a tree on a steep slope. I didn’t properly assess the situation and ended up cutting the tree in a way that caused it to roll downhill. The tree landed on my chainsaw, bending the bar and damaging the engine. It was a costly mistake that could have been avoided with better planning and safer cutting techniques.

Safe Cutting Practices:

Proper Training: Take a chainsaw safety course from a qualified instructor.
Personal Protective Equipment (PPE): Always wear appropriate PPE, including a helmet, eye protection, hearing protection, gloves, chainsaw chaps, and steel-toed boots.
Assess the Situation: Before cutting any tree, assess the situation and identify any potential hazards, such as overhead wires, nearby buildings, or unstable ground.
Plan Your Cut: Plan your cut carefully and consider the direction of the tree’s lean. Use wedges or a felling lever to control the direction of the fall.
Use Proper Cutting Techniques: Use proper cutting techniques, such as the bore cut, the hinge cut, and the back cut, to control the direction of the fall and prevent barber chairing.
Avoid Pinching: Avoid situations that can lead to pinching, such as cutting in tight spaces or felling trees with excessive lean.
Be Aware of Kickback: Be aware of the potential for kickback and take steps to prevent it. Keep the bar nose out of contact with the wood and maintain a firm grip on the saw.
Take Breaks: Take frequent breaks to avoid fatigue. Fatigue can lead to errors in judgment and increase the risk of accidents.
Data Point: According to the Consumer Product Safety Commission (CPSC), there are approximately 30,000 chainsaw-related injuries in the United States each year. Many of these injuries could be prevented with proper training and safe cutting techniques.

Specific Techniques for Longer Bars:

Bore Cutting: Essential for felling large trees with a 36-inch bar. Allows for precise control and reduces the risk of barber chairing.
Hinge Placement: Critical for controlling the direction of the fall. Ensure the hinge is of the correct size and thickness.
Felling Wedges: Indispensable for preventing pinching and controlling the direction of the fall. Use multiple wedges for larger trees.
