Tip 1: Chain Selection & Sharpening – The Foundation of Efficient Cutting

The chain is the heart of your chainsaw’s cutting ability. A dull chain is not only inefficient but also dangerous, requiring more force and increasing the risk of kickback.

Chain Type: Stihl 50cc chainsaws often use 3/8″ pitch chains, but variations exist (e.g., .325″ pitch). The correct chain is crucial. Consult your chainsaw’s manual or the bar itself. I’ve seen firsthand the damage caused by using the wrong chain – increased vibration, premature wear on the bar, and significantly reduced cutting performance.
Sharpening: This is the most critical aspect. I recommend sharpening your chain after every tank of fuel or any time you notice a decrease in cutting speed. A sharp chain pulls itself into the wood, creating large, consistent chips. A dull chain produces fine sawdust and requires excessive pressure.
- Tools: I use a chainsaw sharpening kit with a round file of the correct diameter for my chain’s cutters (usually 5/32″ or 4.8mm for 3/8″ pitch). A depth gauge tool and a flat file are also essential for maintaining the correct depth gauge setting.
- Technique:
  1. Secure the chainsaw in a vise.
  2. Identify the shortest cutter – use this as your guide for sharpening all others.
  3. File each cutter at the correct angle (usually marked on the sharpening kit or chain box). Maintain a consistent angle and pressure. I usually aim for 5-10 strokes per cutter, depending on sharpness.
  4. Lower the depth gauges every 3-5 sharpenings. Use the depth gauge tool to ensure they are slightly below the cutter height.
- Personal Experience: I once neglected chain sharpening during a large firewood processing project. My cutting speed decreased dramatically, and I ended up spending twice as long on the job. Since then, I’ve made sharpening a ritual, and the difference in efficiency is remarkable.
Chain Tension: Proper chain tension is vital for safe and efficient cutting. A chain that is too loose can derail, while one that is too tight can cause excessive wear on the bar and chain. The correct tension allows you to pull the chain away from the bar about 1/8″ to 1/4″ at the midpoint of the bar. Adjust it when the chain is cold and then recheck it after the saw has warmed up, as heat causes the chain to expand.
Data & Insights: I’ve tracked my chain lifespan with and without consistent sharpening. A properly maintained chain lasts approximately 30-40 hours of cutting time, while a neglected chain might only last 10-15 hours. This represents a significant cost saving and reduces downtime.

Tip 2: Mastering Felling Techniques – Precision and Safety First

Felling a tree is a complex process that requires careful planning and execution. Safety is paramount.

Planning: Before making any cuts, assess the tree for lean, wind direction, and any potential hazards (e.g., dead branches, power lines). Determine the desired felling direction and clear the area around the base of the tree. I always clear two escape paths at a 45-degree angle away from the expected fall line.
The Notch: The notch determines the direction of the fall.
- Open Face Notch: I prefer this method for most situations. It consists of a horizontal cut that is about 1/5 to 1/3 of the tree’s diameter, followed by an angled cut that meets the horizontal cut. The angle should be around 45-60 degrees.
- Humboldt Notch: This is a less common type of notch where the angled cut is made first. This is useful for trees that have a forward lean.
- Kerf Width: The kerf (the opening created by the notch) should be wide enough to guide the tree in the desired direction.
The Hinge: The hinge is the uncut wood between the notch and the back cut. It controls the fall of the tree, preventing it from twisting or kicking back. The hinge should be about 1/10 of the tree’s diameter.
The Back Cut: The back cut is made horizontally, slightly above the horizontal cut of the notch. Leave the hinge intact.
Felling Wedges: Use felling wedges to help direct the fall of the tree, especially if it has a backward lean. Insert the wedges into the back cut and drive them in with a hammer or axe.
Safety Precautions:
- Always wear appropriate safety gear: helmet, hearing protection, eye protection, gloves, and chainsaw chaps.
- Be aware of your surroundings and the potential for kickback.
- Never fell a tree alone. Have someone nearby to assist in case of an emergency.
- If you are unsure about any aspect of felling, consult with a professional arborist.
Case Study: I once felled a large oak tree that had a significant backward lean. I used two felling wedges and carefully drove them in, gradually lifting the tree until it began to fall in the desired direction. Without the wedges, the tree would have likely fallen backward, potentially causing damage or injury.
Data & Insights: According to the Occupational Safety and Health Administration (OSHA), improper felling techniques are a leading cause of chainsaw-related injuries. Proper training and adherence to safety guidelines are crucial to preventing accidents.

Tip 3: Bucking Techniques – Efficiently Processing Logs into Manageable Pieces

Bucking is the process of cutting felled trees into shorter lengths.

Safety: Always ensure the log is stable and won’t roll or shift during cutting. Use wedges to support the log if necessary.
Compression and Tension: Understanding compression and tension is crucial for preventing the saw from pinching.
- Compression: The wood fibers are being squeezed together.
- Tension: The wood fibers are being pulled apart.
- Cutting Strategy: Cut on the tension side first. If the log is supported at both ends, make a cut on the top (tension). Then, make a cut on the bottom (compression) to meet the first cut. If the log is supported in the middle, cut on the bottom first (tension) and then on the top (compression).
Cutting Techniques:
- Boring Cut: This technique involves plunging the tip of the saw into the log. It’s useful for relieving compression and creating a starting point for other cuts. Be extremely cautious when using the boring cut, as it can increase the risk of kickback.
- Step Cutting: For larger logs, use a step-cutting technique. Make a series of shallow cuts, gradually working your way through the log.
- Freehand Cutting: For smaller logs, you can cut freehand, but always maintain a firm grip on the saw and keep your body balanced.
Log Splitter Considerations: When bucking logs for firewood, consider the size and type of your log splitter. I generally buck logs to lengths of 16-18 inches, which is suitable for most standard firewood stoves.
Wood Type Selection: Knowing the type of wood you’re cutting is essential. Hardwoods like oak and maple require more power and a sharper chain than softwoods like pine and fir. Adjust your cutting technique accordingly.
Personal Experience: I once bucked a large oak log without properly relieving the compression. The saw pinched, and I had to use a sledgehammer and wedges to free it. Since then, I’ve always taken the time to assess the log and plan my cuts carefully.
Data & Insights: Efficient bucking techniques can significantly increase your productivity. By understanding compression and tension, you can reduce the risk of pinching and speed up the cutting process. I’ve found that using a combination of boring cuts and step cutting allows me to process even the largest logs relatively quickly.

Tip 4: Chainsaw Maintenance – Extending the Life of Your Tool

Regular maintenance is essential for keeping your Stihl 50cc chainsaw running smoothly and reliably.

Air Filter: Clean the air filter after every use. A dirty air filter restricts airflow, reducing engine power and potentially causing damage. I use compressed air to blow out the filter, but you can also wash it with soap and water.
Spark Plug: Check the spark plug regularly for fouling or damage. Replace it every year or as needed.
Fuel Filter: Replace the fuel filter every year. A clogged fuel filter can starve the engine of fuel, causing it to run poorly or stall.
Bar and Chain Oiler: Ensure the bar and chain oiler is functioning properly. The chain needs constant lubrication to prevent excessive wear. Check the oil level regularly and refill as needed. I use a high-quality bar and chain oil specifically designed for chainsaws.
Bar Maintenance:
- Clean the bar groove regularly to remove sawdust and debris.
- Check the bar rails for wear and burrs. Use a bar dressing tool to smooth out any imperfections.
- Flip the bar periodically to ensure even wear on both sides.
Storage: When storing your chainsaw for an extended period, drain the fuel tank and run the engine until it stalls to prevent fuel from gumming up the carburetor. Store the chainsaw in a dry place, away from direct sunlight.
Carburetor Adjustment: If your chainsaw is running poorly, you may need to adjust the carburetor. This is a more advanced procedure and should only be attempted by someone with experience. Consult your chainsaw’s manual or a qualified technician.
Tool Specifications: I keep a log of all maintenance performed on my chainsaw, including the date, type of service, and parts replaced. This helps me track the chainsaw’s performance and identify potential problems early on.
Personal Experience: I once neglected to clean the air filter on my chainsaw during a particularly dusty job. The engine overheated and stalled frequently, and I eventually had to take it to a repair shop. Since then, I’ve made air filter cleaning a top priority.
Data & Insights: Regular maintenance can significantly extend the life of your chainsaw. I’ve found that well-maintained chainsaws can last for 10 years or more, while neglected chainsaws may only last a few years. This represents a significant cost saving in the long run.

Tip 5: Understanding Wood Types and Their Impact on Cutting

The type of wood you’re cutting significantly affects the performance of your chainsaw and the techniques you should employ.

Green Wood vs. Seasoned Wood:
- Green Wood: Wood that has recently been cut and still contains a high moisture content. It’s heavier, denser, and generally easier to split when fresh. However, it’s more prone to warping and cracking during drying.
- Seasoned Wood: Wood that has been allowed to dry, reducing its moisture content. It’s lighter, easier to handle, and burns more efficiently in a stove or fireplace.
Hardwoods vs. Softwoods:
- Hardwoods: Generally denser and more difficult to cut than softwoods. Examples include oak, maple, and birch. They produce more heat when burned but take longer to dry.
- Softwoods: Generally less dense and easier to cut than hardwoods. Examples include pine, fir, and spruce. They ignite easily and burn quickly but produce less heat than hardwoods.
Wood Density and Moisture Content:
- Density: The density of the wood affects the cutting speed and the amount of power required from the chainsaw. Denser woods require a sharper chain and more aggressive cutting techniques.
- Moisture Content: The moisture content of the wood affects the ease of cutting and the amount of sap and resin that can accumulate on the chain and bar. Green wood tends to gum up the chain more quickly than seasoned wood.
Strategic Advantages: Knowing the characteristics of different wood types allows you to select the appropriate chainsaw chain, cutting techniques, and drying methods. For example, if you’re cutting green oak, you’ll need a sharp chain, a powerful chainsaw, and a strategy for preventing the saw from pinching.
Drying Methods:
- Air Drying: The most common method of drying firewood. Stack the wood in a well-ventilated area, off the ground, and cover the top to protect it from rain and snow. Allow the wood to dry for at least six months, preferably a year or more.
- Kiln Drying: A faster method of drying firewood that involves placing the wood in a kiln and using heat to remove the moisture. Kiln-dried firewood is more expensive but burns more efficiently and produces less smoke.
Moisture Content Targets: The ideal moisture content for firewood is 20% or less. You can use a moisture meter to check the moisture content of your firewood.
Personal Experience: I once tried to cut green oak with a dull chain. The saw struggled to cut through the wood, and the chain quickly became gummed up with sap. I learned the hard way that using the right tools and techniques for the specific type of wood you’re cutting is essential.
Data & Insights: The moisture content of firewood significantly affects its burning efficiency. Dry firewood produces more heat and less smoke than wet firewood. I’ve found that air-drying firewood for a year reduces its moisture content to around 15-20%, making it ideal for burning.
