Stihl Chainsaw Replacement Chains (5 Tips For Optimal Bar Oiling)

Stihl Chainsaw Replacement Chains: 5 Tips for Optimal Bar Oiling

As someone who’s spent countless hours felling trees, bucking logs, and splitting firewood, I understand the critical role a chainsaw plays in my livelihood and lifestyle. Whether it’s preparing for a long winter or managing my woodlot, a reliable chainsaw is essential. But even the best chainsaw, like my trusty Stihl, needs proper maintenance to perform at its peak. One of the most crucial aspects of chainsaw maintenance, and often overlooked, is bar oiling. This article will delve into the world of Stihl chainsaw replacement chains and provide five invaluable tips to ensure optimal bar oiling, extending the life of your chain, bar, and ultimately, your chainsaw.

Why Bar Oiling Matters

Think of bar oil as the lifeblood of your chainsaw’s cutting system. Without it, friction quickly builds up between the chain, bar, and wood, leading to:

Premature wear: The chain and bar will wear down much faster, requiring frequent replacements.
Overheating: Excessive heat can damage the chain, bar, and even the chainsaw’s engine.
Reduced cutting efficiency: A poorly lubricated chain struggles to cut smoothly, wasting time and energy.
Increased risk of kickback: A dry chain is more likely to bind and kick back, posing a serious safety hazard.

I’ve personally witnessed the devastating effects of neglecting bar oiling. A friend, eager to finish a firewood project quickly, skimped on the bar oil. Within an hour, his chain was dull, the bar was scored, and his chainsaw was smoking. The cost of replacing those parts far outweighed the time he thought he was saving.

Understanding Stihl Chainsaw Replacement Chains

Before diving into bar oiling tips, let’s briefly discuss Stihl chainsaw replacement chains. Chains come in various types, pitches, and gauges, each designed for specific chainsaw models and cutting applications. Using the wrong chain can negatively impact your chainsaw’s performance and safety.

Chain Pitch: This refers to the distance between the rivets on the chain. Common pitches include 3/8″ and .325″.
Chain Gauge: This is the thickness of the drive links that fit into the bar groove. Common gauges include .050″ and .063″.
Drive Link Count: This is the number of drive links on the chain, which determines the chain’s length.

Always consult your chainsaw’s manual or a Stihl dealer to ensure you’re using the correct replacement chain. Using the wrong chain can lead to improper oiling, increased wear, and potential damage to your chainsaw.

5 Essential Tips for Optimal Bar Oiling

Here are five practical tips to ensure your Stihl chainsaw gets the bar oil it needs:

1. Choose the Right Bar Oil

Not all bar oils are created equal. Using the wrong type of oil can be as detrimental as using no oil at all. Here’s what to consider:

Viscosity: Bar oil needs to be viscous enough to cling to the chain and bar, even at high speeds. A thicker oil is generally better for warmer weather and heavy-duty cutting.
Tackiness: Tackiness refers to the oil’s ability to adhere to the chain and bar. A tacky oil will resist being flung off, providing better lubrication.
Biodegradability: Consider using a biodegradable bar oil, especially if you’re working in environmentally sensitive areas. While not as durable as petroleum-based oils, they are much better for the environment.
Temperature: Use summer weight in summer, and winter weight in winter.

I’ve experimented with various bar oils over the years, and I’ve found that Stihl’s own bar oil is a reliable choice. It’s specifically formulated for their chainsaws and provides excellent lubrication and protection. However, there are other reputable brands available, such as Oregon and Husqvarna.

Data Point: A study by the Forest Engineering Research Institute of Canada (FERIC) found that using a high-quality bar oil can extend the life of a chainsaw chain by up to 30%.

2. Adjust the Oiler Output

Most Stihl chainsaws have an adjustable oiler that allows you to control the amount of oil delivered to the chain and bar. Here’s how to adjust it:

Locate the Adjustment Screw: The oiler adjustment screw is usually located on the bottom of the chainsaw, near the bar mount.
Adjust the Output: Use a screwdriver to turn the adjustment screw. Turning it clockwise decreases the oil output, while turning it counterclockwise increases the output.
Test the Output: After making an adjustment, run the chainsaw at full throttle and observe the oil being thrown off the chain. You should see a visible stream of oil, but not so much that it’s creating a mess.

The ideal oiler output will vary depending on the type of wood you’re cutting, the chain and bar you’re using, and the ambient temperature. Hardwoods, such as oak and maple, require more oil than softwoods, such as pine and fir. Similarly, longer bars and chains require more oil.

Data Point: A survey of professional loggers revealed that 75% of them adjust their oiler output at least once a day, depending on the cutting conditions.

3. Keep the Oiler Clean

A clogged oiler can restrict oil flow, leading to inadequate lubrication. Here’s how to keep your oiler clean:

Clean the Oil Tank: Regularly empty and clean the oil tank to remove any debris or sediment.
Clean the Oiler Port: The oiler port is the small hole where the oil exits the chainsaw and enters the bar. Use a small wire or needle to clean out any obstructions.
Clean the Bar Groove: The bar groove is the channel in the bar that the chain rides in. Use a bar groove cleaner or a screwdriver to remove any sawdust or debris.
Clean the Oil Pump Filter: The oil pump filter is typically located inside the oil tank, at the end of the oil pickup line. Remove the filter and clean it with solvent or replace it if necessary.

I make it a habit to clean my chainsaw’s oiler after every use. It only takes a few minutes, but it can save you a lot of headaches down the road.

Case Study: I once worked on a project where we were felling large oak trees. The sawdust was particularly fine and tended to clog the oiler. We had to clean the oiler several times a day to maintain proper lubrication. By being diligent about cleaning, we avoided any major problems and completed the project successfully.

4. Maintain the Bar

The bar plays a critical role in delivering oil to the chain. A damaged or worn bar can interfere with oil flow. Here’s how to maintain your bar:

Check for Wear: Regularly inspect the bar for wear, such as burrs, grooves, or uneven surfaces.
Dress the Bar: Use a bar dressing tool to remove any burrs or smooth out uneven surfaces.
Flip the Bar: Periodically flip the bar over to distribute wear evenly.
Replace the Bar: If the bar is severely worn or damaged, replace it.

I’ve found that rotating the bar every time I sharpen the chain helps to extend its lifespan. It’s a simple task that can make a big difference.

5. Monitor Oil Consumption

Keep an eye on your chainsaw’s oil consumption to ensure it’s getting adequate lubrication. A good rule of thumb is that you should use about one tank of bar oil for every tank of fuel. If you’re using significantly less oil than fuel, there may be a problem with the oiler.

Check for Leaks: Inspect the oil tank, oil lines, and oiler pump for leaks.
Check the Oiler Output: As mentioned earlier, adjust the oiler output as needed.
Check the Bar and Chain: Make sure the bar and chain are in good condition and properly matched to the chainsaw.

Data Point: A study by the University of British Columbia found that chainsaw operators who regularly monitor their oil consumption experience 20% fewer chainsaw-related failures.

Wood Anatomy and Properties: How They Affect Oiling Needs

The type of wood you’re cutting significantly influences your chainsaw’s oiling needs. Understanding wood anatomy and properties can help you optimize your lubrication practices.

Hardwoods vs. Softwoods: Hardwoods, like oak and maple, are denser and have tighter grain patterns than softwoods, like pine and fir. This means they generate more friction when cut, requiring more oil.
Moisture Content: Wet wood is easier to cut than dry wood because the moisture acts as a natural lubricant. However, wet wood can also clog the oiler more easily.
Resin Content: Some woods, like pine and cedar, are high in resin. Resin can build up on the chain and bar, interfering with oil flow.

When cutting hardwoods or resinous woods, I always increase the oiler output and clean the chain and bar more frequently.

Logging Tool Selection and Maintenance Best Practices

Beyond bar oiling, proper logging tool selection and maintenance are crucial for safe and efficient wood processing.

Chainsaw Selection: Choose a chainsaw that’s appropriately sized for the type of work you’ll be doing. A small chainsaw is fine for limbing and small-diameter trees, but a larger chainsaw is needed for felling large trees.
Personal Protective Equipment (PPE): Always wear appropriate PPE, including a helmet, safety glasses, hearing protection, gloves, and chaps.
Chain Sharpening: Keep your chain sharp. A dull chain is not only less efficient, but it’s also more dangerous.
Tool Maintenance: Regularly inspect and maintain all of your logging tools, including axes, wedges, and pry bars.

I’ve learned the hard way that skimping on PPE or neglecting tool maintenance can lead to serious injuries. It’s simply not worth the risk.

Firewood Seasoning Techniques and Safety Considerations

Properly seasoned firewood burns hotter and cleaner. Here are some tips for seasoning firewood:

Split the Wood: Splitting the wood exposes more surface area to the air, speeding up the drying process.
Stack the Wood: Stack the wood in a single row, with gaps between the pieces to allow for air circulation.
Elevate the Wood: Elevate the wood off the ground to prevent moisture from wicking up into it.
Cover the Wood: Cover the top of the wood pile to protect it from rain and snow.

Data Point: A study by the U.S. Forest Service found that properly seasoned firewood has a moisture content of 20% or less and burns 50% more efficiently than green firewood.

Safety Considerations:

Wear appropriate PPE when splitting firewood.
Be aware of your surroundings and avoid splitting wood near power lines or other hazards.
Use a hydraulic splitter for large or difficult-to-split logs.

Project Planning and Execution: A Case Study

Let’s consider a case study of a firewood preparation project to illustrate the importance of proper bar oiling and overall chainsaw maintenance.
