MS390 Stihl Chainsaw: 5 Pro Hacks for Wood Processing & Cost-Effective Budgeting

The MS390 Stihl chainsaw is a powerful tool. However, like any tool, it’s only as effective as the person using it. Here are five pro hacks, intertwined with cost considerations, to help you get the most out of your MS390.

Hack #1: Sharpening is Paramount – Saving Money One Cut at a Time

A dull chainsaw is not only inefficient, but it’s also dangerous. It requires more force, puts undue strain on the engine, and increases the risk of kickback. A sharp chain, on the other hand, slices through wood with ease, saving you time, fuel, and wear and tear on your saw. This translates directly into cost savings.

• The Cost of Dullness: Running a dull chain means your MS390 will consume more fuel. I’ve seen firsthand how a dull chain can increase fuel consumption by as much as 25%. Considering that a gallon of gasoline can cost anywhere from $3.50 to $5.00 (or more, depending on location and season), this can add up quickly, especially on larger projects. Furthermore, forcing a dull chain through wood puts excessive stress on the engine components, potentially leading to premature wear and costly repairs. A new piston and cylinder kit for an MS390 can easily set you back $150 – $250.

• Sharpening Options and Costs: You have several options for sharpening your chain:

  • Manual Sharpening with a File: This is the most affordable method, requiring only a chainsaw file, a file guide, and some elbow grease. A good quality chainsaw file and guide set will cost around $20-$40. The downside is that it requires practice and patience to achieve consistent results.
  • Electric Chain Sharpener: An electric sharpener provides more consistent and faster results than manual filing. Decent models range from $50 to $150. While the initial investment is higher, it saves time and ensures a more precise sharpening, ultimately extending the life of your chain.
  • Professional Sharpening: Many hardware stores and chainsaw shops offer chain sharpening services. The cost typically ranges from $10 to $20 per chain. While this is convenient, it can become expensive if you need to sharpen your chain frequently.

• My Experience: I learned the hard way about the importance of chain sharpness. Early in my wood processing journey, I neglected sharpening and ended up damaging the bar and chain on my MS390. The repair cost me nearly $100. Now, I make it a habit to sharpen my chain after every few tanks of fuel, or more frequently if I’m cutting dirty or knotty wood. I invested in a decent electric sharpener and learned to use it properly. This has not only saved me money on fuel and repairs but has also made my work safer and more efficient.

• Data Point: According to a study by the US Forest Service, maintaining sharp cutting tools can reduce labor costs in logging operations by up to 15%. This underscores the significant impact of proper tool maintenance on overall project efficiency and cost-effectiveness.

Hack #2: Mastering the Felling Cut – Minimizing Waste and Maximizing Yield

The felling cut is arguably the most crucial step in wood processing. A poorly executed felling cut can result in wasted timber, increased danger, and potential damage to your chainsaw. Mastering this technique not only improves safety but also maximizes the yield from each tree, directly impacting your bottom line.

• The Cost of Poor Felling: An improper felling cut can lead to the tree splitting or barber chairing (splitting vertically upwards), resulting in significant timber loss. Consider the cost of timber: depending on the species and location, a standing tree can be worth anywhere from a few dollars to hundreds of dollars. Wasting even a small portion of that tree due to a bad felling cut translates directly into lost revenue. Furthermore, a poorly felled tree can damage your chainsaw if it falls unexpectedly or pinches the bar. Replacing a bent or broken bar can cost $50 – $80.

• Felling Techniques and Costs:

  • Proper Notch Creation: The notch, typically a 70-degree open-faced notch, dictates the direction of the fall. An accurate notch ensures the tree falls where you intend, minimizing the risk of damage to other trees or property.
  • Hinge Wood: The hinge is the uncut wood between the notch and the felling cut. It controls the fall of the tree and prevents it from kicking back. The size and thickness of the hinge are crucial for safe and controlled felling.
  • Bore Cutting: In some cases, bore cutting (plunging the tip of the chainsaw into the tree to create a relief cut) is necessary to prevent barber chairing. This technique requires skill and caution.

• My Experience: I once witnessed a novice logger attempt to fell a large oak tree without properly creating a notch. The tree fell in the opposite direction, narrowly missing his truck and causing significant damage to a nearby fence. The cost of repairing the fence and removing the tree from the fence line far outweighed the value of the timber he harvested. This incident reinforced the importance of proper training and technique in felling operations.

Hack #3: Chain and Bar Maintenance – Extending Lifespan and Reducing Replacement Costs

The chain and bar are the heart and soul of your MS390. Proper maintenance of these components is essential for optimal performance and longevity. Neglecting chain and bar maintenance can lead to premature wear, reduced cutting efficiency, and costly replacements.

  • Chain Sharpening and Filing: As mentioned earlier, keeping your chain sharp is crucial. Regular filing and sharpening not only improve cutting efficiency but also prevent excessive wear on the bar.
  • Bar Oiling: Proper lubrication is essential for reducing friction between the chain and the bar. Use a high-quality bar and chain oil and ensure the oiler is functioning correctly. Insufficient lubrication can lead to premature wear and damage to both the chain and the bar. A gallon of good quality bar and chain oil costs about $15-$25.
  • Bar Cleaning and Grooving: Regularly clean the bar groove to remove sawdust and debris. This ensures proper oil flow and prevents the chain from binding. Use a bar groove cleaner or a small screwdriver to remove debris.
  • Bar Dressing: Use a bar dresser to remove burrs and flatten the bar rails. This helps maintain proper chain alignment and prevents premature wear. A bar dresser costs around $20 – $30.
  • Chain Tensioning: Maintaining proper chain tension is crucial for safe and efficient cutting. A loose chain can derail and cause injury, while an overtight chain can bind and overheat, leading to premature wear.

• My Experience: I once neglected to properly lubricate my chain and ended up burning out the bar. The heat and friction caused the bar to warp and the chain to bind. Replacing the bar and chain cost me over $100. Since then, I’ve been meticulous about bar and chain maintenance, and I’ve noticed a significant improvement in the lifespan of these components.

• Data Point: According to a study by a leading chainsaw manufacturer, proper chain and bar maintenance can extend the lifespan of these components by up to 50%. This highlights the significant cost savings associated with regular maintenance practices.
