I’ll also delve into the often-murky world of wood processing and firewood preparation costs, providing a data-driven guide to budgeting your projects effectively.

Stihl Chainsaw MS 660 Tips for 48″ Bars (5 Expert Hacks)

The Stihl MS 660 is a beast of a machine, a workhorse capable of felling large trees and handling demanding milling tasks. However, pairing it with a 48-inch bar requires careful attention to technique and maintenance to ensure optimal performance and prevent premature wear. After many years of working with this equipment, I’ve learned a few hacks that can make a significant difference.

1. Oiling is Everything: Mastering Lubrication for Long Bars

The single most crucial aspect of running a 48-inch bar on your MS 660 is adequate lubrication. Insufficient oil leads to friction, heat buildup, and rapid wear on the bar, chain, and even the saw’s engine. This translates to higher maintenance costs and a shorter lifespan for your equipment.

• The Problem: Long bars require significantly more oil than shorter bars. The longer the bar, the greater the surface area that needs lubrication, and the further the oil needs to travel. Many stock oil pumps on the MS 660 struggle to keep up with the demands of a 48-inch bar, especially when cutting hardwoods.

• The Hack: Upgrade Your Oil Pump. Consider upgrading to a high-output oil pump. Stihl offers upgraded pumps specifically designed for longer bars. These pumps deliver a higher volume of oil, ensuring adequate lubrication even in demanding conditions. I personally upgraded to the Stihl high-output pump (part number varies by model year – consult your dealer) and noticed a significant difference, especially when milling oak and maple.

• Data Point: A study by Oregon Products found that inadequate chain lubrication can reduce chain lifespan by up to 50% and bar lifespan by 30%.
• The Test: Perform the “cardboard test.” Start your saw and hold the bar tip approximately 6 inches above a piece of cardboard. Run the saw at full throttle for a few seconds. A healthy oiler should leave a visible spray of oil on the cardboard. If the spray is weak or nonexistent, your oiler needs attention.
• Oil Type Matters: Use a high-quality bar and chain oil specifically formulated for chainsaws. Avoid using motor oil or other substitutes, as they lack the necessary tackifiers and anti-wear additives. I prefer using a synthetic blend oil in colder weather, as it flows more easily and provides better lubrication at lower temperatures.
• Practical Tip: Adjust your oiler to the maximum setting, especially when using a 48-inch bar. Monitor oil consumption closely. You should be using approximately one tank of oil for every tank of fuel.

2. Chain Tension: Finding the Sweet Spot

Maintaining proper chain tension is critical for safety, performance, and the longevity of your bar and chain. Too loose, and the chain can derail, causing damage and potential injury. Too tight, and you’ll experience excessive friction, heat, and wear.

• The Problem: Long bars are more susceptible to chain stretch than shorter bars. The longer chain length means more links to stretch and sag, especially during initial break-in or when cutting dense hardwoods.
• The Hack: Frequent Tension Checks. Check chain tension frequently, especially during the first few hours of use with a new chain. A new chain will stretch significantly during its initial break-in period. I typically check the tension after every few cuts, and certainly after every refuel.
• The Technique: With the saw off and the bar cool, the chain should be snug against the bottom of the bar but still able to be pulled around the bar by hand. There should be minimal sag on the underside of the bar.
• Hot Tension Adjustment: If you need to adjust the chain tension while the bar is hot, loosen the chain slightly more than you would when cold. As the bar and chain cool, they will contract, tightening the chain.
• Bar Wear Indicators: Pay attention to the wear indicators on your bar. These are small markings that show the ideal chain tension. If the chain is consistently too tight or too loose, it can accelerate wear on the bar rails.
• Personal Story: I once ignored a slightly loose chain while felling a large oak. The chain derailed mid-cut, damaging the bar and nearly causing a kickback. It was a costly lesson in the importance of proper chain tension.

3. Sharpening: The Key to Efficient Cutting and Reduced Strain

A dull chain is not only inefficient, but it also puts unnecessary strain on your saw’s engine and bar. A sharp chain cuts faster, smoother, and with less effort, reducing fuel consumption and extending the life of your equipment.

• The Problem: Cutting with a dull chain requires more force, which increases friction and heat. This can lead to premature wear on the bar, chain, and engine. It also increases the risk of kickback.
• The Hack: Sharpen Regularly and Correctly. Sharpen your chain frequently, ideally before it becomes noticeably dull. I prefer to sharpen my chains after every refueling.
• Consistent Angle: Use a file guide to ensure consistent sharpening angles. Maintaining the correct angles is crucial for optimal cutting performance and chain longevity. I use a Stihl filing guide, but there are many excellent aftermarket options available.
• Depth Gauge Maintenance: Pay attention to the depth gauges (rakers). These control the amount of wood each tooth takes with each pass. If the depth gauges are too high, the chain will cut slowly. If they are too low, the chain will grab and kick. Use a depth gauge tool to maintain the correct height.
• Sharpening Technique: File each tooth evenly, using smooth, consistent strokes. Avoid applying excessive pressure, as this can damage the tooth. After sharpening, use a flat file to remove any burrs from the cutting edges.
• Chain Grinder: For heavily damaged chains or for faster sharpening, consider using a chain grinder. A grinder can quickly and accurately restore the cutting edges of your chain. However, it’s important to use the correct grinding wheel and settings to avoid overheating the chain.

4. Bar Maintenance: Preventing Premature Wear and Damage

The bar is a critical component of your chainsaw, and proper maintenance is essential for its longevity and performance. Neglecting bar maintenance can lead to premature wear, damage, and reduced cutting efficiency.

• The Problem: The bar rails are subjected to constant friction from the chain. Over time, this can cause wear, burrs, and unevenness, leading to poor chain tracking and increased friction.
• The Hack: Regular Bar Dressing. Regularly dress the bar rails using a bar dressing tool. This tool removes burrs, smooths out the rails, and ensures proper chain tracking. I dress my bar rails every time I sharpen my chain.
• Bar Rotation: Rotate the bar regularly to distribute wear evenly. Most bars are designed to be reversible. Flipping the bar over will allow the opposite side of the rails to wear, extending the bar’s lifespan.
• Cleaning: Keep the bar clean. Remove sawdust and debris from the bar groove regularly. A clogged groove can restrict oil flow and cause excessive friction.
• Bar Oil Hole Maintenance: Ensure the bar oil hole is clear and unobstructed. Use a small wire or pick to remove any debris that may be blocking the hole.
• Bar Inspection: Inspect the bar regularly for signs of wear or damage. Look for cracks, bends, or excessive wear on the rails. Replace the bar if it is damaged or worn beyond repair.

5. Milling with a 48″ Bar: Special Considerations

Using a 48-inch bar for milling puts even greater demands on your saw and requires special attention to technique and setup. Milling involves cutting long, straight boards from logs, and it requires precise control and consistent power.

• The Problem: Milling generates a lot of sawdust, which can quickly clog the saw and bar. It also requires a lot of power, which can overheat the engine if the saw is not properly tuned and maintained.
• The Hack: Use a Milling Attachment. Invest in a proper milling attachment. These attachments provide a stable platform for the saw and help guide it through the cut. There are several types of milling attachments available, including Alaskan mills and slabbing mills.
• Sharp Chain is Essential: Use a dedicated milling chain. Milling chains have a different tooth geometry than standard chains, designed for making smooth, clean cuts. They also tend to have a lower raker height. Keep this chain extremely sharp.
• Slow and Steady: Cut slowly and steadily. Avoid forcing the saw, as this can lead to overheating and damage. Let the saw do the work.
• Clear Sawdust Regularly: Clear sawdust from the cut frequently. Use a brush or compressed air to remove sawdust from the bar, chain, and milling attachment.
• Two-Man Operation: Consider a two-man operation for larger logs. Having a second person to help guide the saw and clear sawdust can significantly improve efficiency and reduce strain.
• Tuning: Ensure your MS 660 is properly tuned for milling. Milling requires a lot of power, and a properly tuned saw will run cooler and more efficiently. Consult your Stihl dealer for tuning recommendations. I slightly richen the high-speed mixture when milling to provide extra lubrication and cooling.
