Safety First: Your Most Important Tool

Before you even think about firing up your MS 270, you need to prioritize safety. Chainsaws are powerful tools, and they can be extremely dangerous if not used properly. I’ve seen firsthand the devastating consequences of chainsaw accidents, and I can’t stress enough the importance of taking safety precautions seriously.

Essential Safety Gear

• Chainsaw Chaps: These are a must-have. They’re designed to stop the chain in the event of a kickback or accidental contact with your legs. Look for chaps that meet ANSI standards.
• Helmet with Face Shield and Ear Protection: A helmet protects your head from falling branches and debris, while the face shield protects your eyes from flying wood chips. Ear protection is essential to prevent hearing damage from the chainsaw’s noise.
• Gloves: Sturdy gloves provide a good grip and protect your hands from cuts and abrasions.
• Steel-Toed Boots: These protect your feet from falling logs and accidental contact with the chainsaw.
• Eye Protection (Even with a Face Shield): Wear safety glasses or goggles under your face shield for an extra layer of protection.
• First-Aid Kit: Keep a well-stocked first-aid kit on hand in case of an injury. Make sure it includes items like bandages, antiseptic wipes, and a tourniquet.

Expert Insight: According to the Occupational Safety and Health Administration (OSHA), most chainsaw injuries occur to the legs and hands. Investing in high-quality safety gear is a small price to pay for protecting yourself from serious injury.

Pre-Cutting Checklist

Before you start cutting, take a few minutes to inspect your work area and your chainsaw.

• Clear the Area: Remove any obstacles, such as branches, rocks, or debris, from your work area.
• Check for Overhead Hazards: Be aware of any overhead hazards, such as dead branches or power lines.
• Inspect Your Chainsaw: Check the chain tension, oil level, and fuel level. Make sure the chain is sharp and the safety features are working properly.
• Plan Your Escape Route: Identify a clear escape route in case of a kickback or falling tree.
• Inform Someone of Your Location: Let someone know where you’ll be working and when you expect to be finished.

Personal Story: I once started cutting without properly clearing the area and tripped over a hidden root. Luckily, I was able to drop the chainsaw before I fell, but it was a close call. Now, I always take the time to clear the area thoroughly before I start cutting.

Understanding Kickback

Kickback is one of the most common and dangerous chainsaw hazards. It occurs when the upper tip of the guide bar contacts an object, causing the saw to suddenly kick back towards the operator.

• Causes of Kickback: Kickback can be caused by contacting a knot, a branch, or the ground with the upper tip of the guide bar. It can also be caused by pinching the chain in the cut.
• Preventing Kickback:
  • Use the Proper Cutting Technique: Avoid using the upper tip of the guide bar.
  • Maintain a Sharp Chain: A dull chain is more likely to kick back.
  • Keep a Firm Grip: Use both hands to grip the chainsaw firmly.
  • Stand to the Side: Position yourself to the side of the log you’re cutting, rather than directly behind it.
  • Be Aware of Your Surroundings: Pay attention to your surroundings and avoid cutting in areas with a lot of obstacles.
  • Use a Chainsaw with Anti-Kickback Features: Many chainsaws, including the Stihl MS 270, have anti-kickback features, such as a chain brake and a reduced-kickback chain.

Data Point: According to the Consumer Product Safety Commission (CPSC), kickback is responsible for approximately 40% of chainsaw injuries.

Safe Starting Procedures

Starting a chainsaw can be tricky, especially if you’re not familiar with the process. Here’s a step-by-step guide to starting the Stihl MS 270 safely:

1. Place the Chainsaw on a Firm, Flat Surface: Make sure the chain is not touching anything.
2. Engage the Chain Brake: This prevents the chain from moving during starting.
3. Activate the Choke: This provides a richer fuel mixture for starting. The choke lever is typically located near the carburetor.
4. Pull the Starter Cord: Pull the starter cord firmly and repeatedly until the engine starts.
5. Disengage the Choke: Once the engine starts, disengage the choke.
6. Let the Engine Warm Up: Allow the engine to warm up for a few minutes before cutting.

Pro Tip: If the chainsaw doesn’t start after a few pulls, try flooding the engine by holding the throttle wide open while pulling the starter cord. This will help clear out any excess fuel.

Mastering the Cutting Techniques: From Log to Firewood

Now that you’ve got the safety basics down, let’s talk about cutting techniques. Efficient and safe cutting techniques are essential for maximizing your productivity and minimizing your risk of injury.

Bucking: Cutting Logs into Manageable Lengths

Bucking is the process of cutting logs into shorter lengths, typically 16-24 inches for firewood. This is a crucial step in preparing firewood, as it makes the wood easier to split and stack.

• Choosing the Right Length: The optimal length for your firewood depends on the size of your wood stove or fireplace. Consult your appliance’s manual for recommendations.
• Supporting the Log: Before you start cutting, make sure the log is properly supported. Use log stands, sawhorses, or other supports to keep the log from rolling or pinching the chain.
• The Two-Cut Method: This is a safe and effective method for bucking logs.
  1. First Cut: Make a cut approximately one-third of the way through the log from the top.
  2. Second Cut: Make a cut from the bottom, slightly overlapping the first cut. This will prevent the log from pinching the chain and causing a kickback.

Illustration: Imagine a log resting on two supports. If you cut straight through from the top, the weight of the log can pinch the chain as you near the bottom, leading to kickback. The two-cut method alleviates this pressure.

• Cutting on a Slope: When cutting logs on a slope, always stand uphill from the log to avoid having it roll towards you.
• Avoiding Pinching: If the chain starts to pinch, stop cutting immediately and use a wedge to open the cut.

Case Study: A study by the University of Maine found that using proper bucking techniques can increase firewood cutting efficiency by up to 25%.

Limbing: Removing Branches from Trees

Limbing is the process of removing branches from felled trees. This is an important step in preparing the tree for bucking and splitting.

• Working from the Bottom Up: Start by removing the lower branches and work your way up the tree. This will prevent branches from falling on you as you work.
• Cutting on the Compression Side: When cutting a branch that is under compression (i.e., being squeezed), make the first cut on the compression side. This will prevent the branch from pinching the chain.
• Using the “Hinge” Technique: When cutting larger branches, use the “hinge” technique. Make a cut on the underside of the branch, then make a second cut from the top, leaving a small “hinge” of wood. This will prevent the branch from falling prematurely and potentially injuring you.
• Avoiding Contact with the Ground: Avoid cutting branches that are touching the ground, as this can dull the chain and increase the risk of kickback.

Personal Story: I once tried to limb a tree without working from the bottom up. A large branch fell on me, knocking me to the ground. Luckily, I wasn’t seriously injured, but it taught me a valuable lesson about the importance of working safely.

Splitting: Turning Logs into Firewood

Splitting is the process of breaking logs into smaller pieces that are suitable for burning in a wood stove or fireplace.

• Choosing the Right Tool: You can split wood with a splitting axe, a maul, or a hydraulic log splitter. The best tool for the job depends on the size and type of wood you’re splitting.
• Splitting Axe vs. Maul: A splitting axe is lighter and easier to swing than a maul, but it’s not as effective for splitting large, knotty logs. A maul is heavier and more powerful, making it better suited for splitting tough wood.
• Hydraulic Log Splitter: A hydraulic log splitter is the most efficient way to split wood, especially if you have a large quantity to process.
• Splitting Technique:
  1. Position the Log: Place the log on a solid, stable surface, such as a chopping block.
  2. Aim for the Center: Aim for the center of the log, avoiding knots and other imperfections.
  3. Swing with Power: Swing the axe or maul with a smooth, controlled motion, using your entire body to generate power.
  4. Follow Through: Follow through with your swing, allowing the axe or maul to split the log completely.

Data Point: A study by the Forest Products Laboratory found that the average person can split approximately 1 cord of firewood per day using a splitting axe or maul. A hydraulic log splitter can increase this to 3-5 cords per day.

• Splitting Knotty Wood: Knotty wood can be difficult to split. Try splitting the log around the knot, or use a wedge to split the knot itself.
• Splitting Green Wood: Green wood is easier to split than dry wood. If possible, split your firewood while it’s still green.

Stacking: Preparing Firewood for Drying

Once you’ve split your firewood, you need to stack it properly to allow it to dry. Dry firewood burns more efficiently and produces less smoke than wet firewood.

• Choosing a Location: Choose a location that is sunny, well-ventilated, and away from your house.
• Building a Stable Stack: Stack the firewood in rows, leaving gaps between the rows to allow for air circulation.
• Elevating the Stack: Elevate the stack off the ground to prevent moisture from wicking up into the wood. You can use pallets, cinder blocks, or other materials to elevate the stack.
• Covering the Stack: Cover the top of the stack with a tarp or other waterproof material to protect it from rain and snow. Leave the sides of the stack open to allow for air circulation.

Pro Tip: Stack your firewood in a single row, rather than a double row, to maximize air circulation.

• Drying Time: Firewood typically takes 6-12 months to dry properly. The drying time depends on the type of wood, the climate, and the stacking method.
• Checking for Dryness: You can check for dryness by splitting a piece of wood and examining the end grain. Dry wood will have cracks and checks in the end grain, while wet wood will be smooth and moist.
