Expert Insight 1: Mastering the Starting Procedure

Starting a chainsaw correctly is fundamental for safety and longevity. The Stihl MS 260, like most chainsaws, requires a specific starting sequence. This is not just about pulling the cord; it’s about understanding the engine and its needs.

Step-by-Step Starting Guide

Safety First: Ensure the chain brake is engaged. This prevents the chain from moving during startup, a crucial safety precaution. Place the saw on a stable, flat surface.
Choke Engagement: If the engine is cold, fully engage the choke. This enriches the fuel mixture to aid starting. With the MS 260, this usually involves moving the choke lever to the topmost position. I always double-check that the lever is fully engaged.
Purging the Carburetor: Press the purge bulb (if equipped) several times until fuel is visible in the bulb. This primes the carburetor and ensures fuel is readily available. This is particularly important after the saw has been sitting for a while.
Pulling the Starter Cord: Grip the starter handle firmly and pull the cord briskly. Avoid pulling the cord all the way out, as this can damage the mechanism. After a few pulls, the engine should “pop” or sputter.
Disengaging the Choke: Once the engine pops, disengage the choke to the half-choke position (usually the middle position on the lever). This leans out the fuel mixture for smoother running.
Final Start: Continue pulling the starter cord until the engine starts and runs smoothly. If the engine floods (smells strongly of fuel), disengage the choke completely and pull the cord several times to clear the excess fuel.
Warming Up: Allow the engine to warm up for a minute or two before engaging the throttle. This allows the oil to circulate and lubricate the engine components.

Common Starting Problems and Solutions

Engine Won’t Start (Cold): Ensure the choke is fully engaged and the fuel is fresh. Old fuel can degrade and make starting difficult. I always recommend using fuel stabilizer, especially if the saw will be stored for an extended period.
Engine Floods: Disengage the choke and pull the cord repeatedly to clear the excess fuel. Let the saw sit for a few minutes before attempting to restart.
Engine Starts but Stalls: The carburetor may need adjustment. Consult a qualified technician or the owner’s manual for adjustment procedures.
Hard to Pull Cord: The spark plug may be fouled, or the piston may be seized. Check the spark plug and replace if necessary. If the piston is seized, the engine may require more extensive repairs.

My Personal Story: The Importance of Fresh Fuel

I once spent an entire morning trying to start my MS 260 after it had been sitting unused for a few months. I went through all the troubleshooting steps, but nothing seemed to work. Finally, I realized that the fuel had gone stale. I drained the old fuel, filled the tank with fresh fuel, and the saw started on the second pull. This experience taught me the importance of using fresh fuel and fuel stabilizer.

Expert Insight 2: Mastering Chainsaw Safety Techniques

Chainsaw safety is paramount. It’s not just about avoiding injuries; it’s about respecting the power of the tool and understanding the risks involved. I’ve witnessed too many accidents caused by carelessness or lack of training.

Essential Safety Gear

Helmet with Face Shield and Ear Protection: Protects your head, face, and hearing from flying debris and noise. I never operate a chainsaw without a helmet.
Chainsaw Chaps: Provide crucial leg protection in case of accidental contact with the chain. Chaps are designed to stop the chain from cutting through to your skin.
Gloves: Improve grip and protect your hands from cuts and abrasions. I prefer gloves with reinforced palms for added protection.
Steel-Toed Boots: Protect your feet from falling logs and accidental contact with the chain.
High-Visibility Clothing: Makes you more visible to others, especially in wooded areas.

Safe Cutting Practices

Maintain a Solid Stance: Keep your feet firmly planted and shoulder-width apart. This provides a stable base and prevents you from losing balance.
Use Both Hands: Always hold the chainsaw with both hands. This gives you better control and reduces the risk of kickback.
Keep the Chain Sharp: A sharp chain cuts more efficiently and reduces the risk of kickback. I sharpen my chain regularly, usually after every few hours of use.
Avoid Cutting Above Shoulder Height: This increases the risk of losing control and dropping the saw.
Be Aware of Your Surroundings: Look for obstacles, such as rocks, branches, and power lines. Also, be aware of other people in the area.
Never Cut Alone: Always have someone nearby in case of an emergency.

Understanding Kickback

Kickback is the sudden and forceful upward or backward movement of the chainsaw when the tip of the bar contacts a solid object. It’s one of the most common causes of chainsaw injuries.

Causes of Kickback: Kickback can occur when the tip of the bar contacts a knot, branch, or other solid object. It can also occur if the chain is pinched or bound in the cut.
Preventing Kickback:
- Use a chainsaw with a chain brake.
- Avoid cutting with the tip of the bar.
- Keep the chain sharp.
- Maintain a firm grip on the saw.
- Be aware of your surroundings.
Kickback Reduction Features: Some chainsaws are equipped with kickback reduction features, such as low-kickback chains and reduced-kickback bars. These features can help to reduce the severity of kickback.

My Personal Story: A Near Miss with Kickback

I once experienced a near-miss with kickback while cutting a small tree. The tip of the bar contacted a hidden knot, and the saw kicked back violently. Fortunately, I was wearing proper safety gear and was able to maintain control of the saw. This experience reinforced the importance of being aware of the risks of kickback and taking steps to prevent it.

Expert Insight 3: Felling Techniques for Safety and Efficiency

Felling trees safely and efficiently is a critical skill for anyone involved in logging or firewood production. Improper felling techniques can lead to serious injuries or damage to property.

Planning the Felling Operation

Assess the Tree: Evaluate the tree’s size, lean, and condition. Look for signs of decay, disease, or damage. I always check for widowmakers (loose branches that could fall during felling).
Plan the Escape Route: Identify a clear escape route at a 45-degree angle from the direction of fall. Clear any obstacles from the escape route.
Consider the Wind: The wind can significantly affect the direction of fall. Avoid felling trees in high winds.
Identify Hazards: Look for power lines, buildings, roads, and other hazards in the area.

Felling Cuts

The Notch: The notch determines the direction of fall. It should be cut on the side of the tree facing the desired direction of fall.
- Open Face Notch: A common notch used for general felling. It consists of a horizontal cut and an angled cut that meet to form a wedge. The angle of the notch should be about 45 degrees.
- Humboldt Notch: Used for larger trees or trees with a significant lean. It consists of two angled cuts that meet to form a wedge. The angle of the notch is typically greater than 45 degrees.
The Hinge: The hinge controls the fall of the tree and prevents it from kicking back or twisting. It should be about 10% of the tree’s diameter.
The Back Cut: The back cut is made on the opposite side of the tree from the notch. It should be slightly above the horizontal cut of the notch. Leave enough wood to create the hinge.

Felling Wedges

Felling wedges are used to help direct the fall of the tree and prevent the saw from being pinched in the cut.

Types of Wedges: Plastic wedges are lightweight and durable. Metal wedges are stronger but can damage the chain if they come into contact with it.
Using Wedges: Insert the wedge into the back cut and drive it in with a hammer or axe. Continue driving the wedge until the tree starts to lean in the desired direction.

My Personal Story: Learning from an Experienced Logger

I learned the art of felling trees from an experienced logger who had been working in the woods for over 40 years. He taught me the importance of planning, assessing the tree, and using proper cutting techniques. He also emphasized the need for patience and caution. One of his key pieces of advice was, “Always respect the tree. It can kill you if you’re not careful.”

Expert Insight 4: Bucking and Limbing Techniques

Once the tree is on the ground, the next step is to buck it into manageable lengths and remove the limbs. These tasks require careful planning and execution to ensure safety and efficiency.

Limbing

Working Position: Position yourself on the uphill side of the tree. This prevents the tree from rolling onto you.
Cutting Technique: Use a smooth, controlled motion to cut the limbs. Avoid cutting towards yourself or others.
Supporting the Tree: Support the tree with your body or a log to prevent it from rolling or shifting.
Removing Spring Poles: Be careful when removing spring poles (limbs that are under tension). These limbs can snap back violently when cut.

Bucking

Planning the Cuts: Plan the cuts to maximize the yield of usable wood. Consider the size and shape of the logs.
Supporting the Log: Support the log to prevent it from pinching the chain. Use wedges or other logs to create a gap under the cut.
Cutting Technique: Use a smooth, controlled motion to cut the log. Avoid cutting through knots or other obstacles.
Avoiding Pinching: If the chain starts to pinch, stop cutting and insert a wedge into the cut. This will relieve the pressure and allow you to continue cutting.

Methods for Bucking

Bucking on the Ground: This method is suitable for small logs. Support the log with branches or other logs to prevent the chain from pinching.
Bucking with a Sawbuck: A sawbuck is a frame that supports the log and makes it easier to cut. This method is suitable for medium-sized logs.
Bucking with a Log Splitter: Some log splitters can be used to buck logs as well as split them. This method is suitable for large logs. I’ve found this particularly useful for processing large rounds of oak.

My Personal Story: The Importance of Proper Support

I once bucked a large log without properly supporting it. As I neared the end of the cut, the log shifted and pinched the chain. The saw kicked back violently, and I narrowly avoided injury. This experience taught me the importance of properly supporting logs before cutting them.

Expert Insight 5: Chainsaw Maintenance for Longevity and Performance

Proper chainsaw maintenance is essential for ensuring its longevity and performance. Regular maintenance can prevent costly repairs and extend the life of the saw.

My Personal Story: The Importance of a Sharp Chain

I once tried to cut a large log with a dull chain. The saw struggled to cut through the wood, and I had to apply a lot of pressure. The saw overheated, and the chain broke. This experience taught me the importance of keeping the chain sharp. A sharp chain cuts more efficiently, reduces the risk of kickback, and extends the life of the saw.

Beyond the Basics: Advanced Techniques and Insights

While the above provides a solid foundation, let’s delve into some advanced techniques and insights that can further enhance your wood processing skills.

Wood Identification: Knowing Your Species

Understanding the properties of different wood species is crucial for efficient firewood preparation and wood processing.

Hardwoods vs. Softwoods: Hardwoods (e.g., oak, maple, beech) are denser and burn longer than softwoods (e.g., pine, fir, spruce). Hardwoods are generally preferred for firewood due to their higher heat output.
Moisture Content: Green wood (freshly cut) has a high moisture content (often above 50%). Seasoned wood (air-dried) has a lower moisture content (ideally below 20%). Seasoned wood burns more efficiently and produces less smoke.
Splitting Difficulty: Some wood species are easier to split than others. Straight-grained woods like ash and maple split easily, while knotty or twisted woods like elm and sycamore can be challenging.

Strategic Firewood Stacking

Proper firewood stacking is essential for efficient drying and storage.

Location: Choose a sunny, well-ventilated location. Avoid stacking firewood directly on the ground, as this can promote rot.
Stacking Method:
- Traditional Rows: Stack the firewood in rows, leaving gaps between the rows for air circulation.
- Circular Stacks (Holz Hausen): A decorative and functional method of stacking firewood in a circular shape. The center of the stack is left open for ventilation.
Covering the Stack: Cover the top of the stack with a tarp or other waterproof material to protect the firewood from rain and snow. Leave the sides of the stack uncovered to allow for air circulation.

Hydraulic Log Splitters: Boosting Efficiency

For large-scale firewood production, a hydraulic log splitter can significantly increase efficiency.

Types of Log Splitters:
- Electric Log Splitters: Suitable for small to medium-sized logs.
- Gas-Powered Log Splitters: Suitable for large logs and heavy-duty use.
Tonnage: The tonnage of a log splitter indicates the amount of force it can exert. Choose a log splitter with sufficient tonnage for the size and type of logs you will be splitting. I recommend at least 20 tons for hardwoods.
Safety Features: Look for a log splitter with safety features such as two-handed operation and a safety cage.
