Understanding Chainsaw Chains for Demolition

The selection of the right chainsaw chain is fundamental to safe and effective wood demolition. Chains aren’t one-size-fits-all. Different types are designed for specific tasks, and using the wrong one can lead to inefficient cutting, increased kickback risk, and premature wear.

Types of Chainsaw Chains

Full-Chisel Chains: These chains have square-cornered teeth, providing the fastest and most efficient cutting in clean wood. However, they are more prone to kickback and dull quickly when encountering dirt or nails, making them less suitable for demolition work where debris is common.
Semi-Chisel Chains: Featuring rounded corners on the teeth, semi-chisel chains offer a good balance between cutting speed and durability. They are more forgiving when cutting dirty or knotty wood than full-chisel chains, making them a versatile choice for demolition.
Low-Profile Chains: These chains have a smaller cutter and a reduced kickback tendency. They are ideal for beginners or those who prioritize safety over speed. While they may not be the fastest option for demolition, they provide a safer and more controlled cutting experience.
Ripping Chains: Designed for cutting wood along the grain, ripping chains have a unique tooth geometry that allows for smooth and efficient milling. They are not typically used for demolition, where cross-grain cutting is more common.

Chain Pitch and Gauge

Understanding chain pitch and gauge is critical for proper chain selection and chainsaw maintenance. The pitch refers to the distance between any three consecutive rivets divided by two, typically measured in inches (e.g., 0.325″, 3/8″, 0.404″). The gauge is the thickness of the drive links that fit into the chainsaw bar groove, usually expressed in thousandths of an inch (e.g., 0.050″, 0.058″, 0.063″).

Matching Pitch and Gauge: It is essential to match the chain pitch and gauge to the specifications of your chainsaw bar and sprocket. Using an incompatible chain can lead to poor performance, chain damage, and potential safety hazards. I once learned this the hard way when I mistakenly fitted a 0.325″ pitch chain on a bar designed for 3/8″ pitch. The chain constantly derailed, and the saw vibrated violently.
Chain Identification: Always refer to your chainsaw’s user manual or the markings on the bar to determine the correct chain pitch and gauge. If you are unsure, consult with a qualified chainsaw technician or retailer.

Hardened Chains for Demolition

For demolition work, consider using chains with carbide-tipped teeth or hardened steel. These chains are more resistant to wear and can withstand the abuse of cutting through dirty or contaminated wood. While they are more expensive than standard chains, they offer a longer lifespan and improved performance in demanding conditions.

Pro Tip 1: Gear Up – Essential Safety Equipment

Safety is paramount when using a chainsaw for demolition. The right personal protective equipment (PPE) can significantly reduce the risk of injury.

Head Protection

Hard Hat: A hard hat is crucial for protecting your head from falling debris, branches, and other hazards. Look for a hard hat that meets ANSI Z89.1 standards and fits comfortably. I once had a close call when a small section of a decaying beam fell directly onto my hard hat. Without it, the impact could have caused a serious head injury.

Eye and Face Protection

Safety Glasses or Goggles: Safety glasses or goggles are essential for protecting your eyes from flying wood chips, sawdust, and other debris. Choose eyewear that meets ANSI Z87.1 standards and provides a snug fit.
Face Shield: A face shield offers additional protection for your face and neck. It is particularly useful when cutting overhead or in situations where there is a high risk of flying debris.

Hearing Protection

Earplugs or Earmuffs: Chainsaws can generate noise levels exceeding 100 decibels, which can cause permanent hearing damage. Use earplugs or earmuffs with a Noise Reduction Rating (NRR) of at least 25 dB to protect your hearing. I learned this lesson early in my career after experiencing ringing in my ears after prolonged chainsaw use without adequate protection.

Hand and Arm Protection

Chainsaw Gloves: Chainsaw gloves are designed with reinforced padding and cut-resistant materials to protect your hands from cuts and abrasions. Look for gloves that fit snugly and provide a good grip.
Chainsaw Chaps or Pants: Chainsaw chaps or pants are essential for protecting your legs from accidental contact with the chain. They are made with multiple layers of ballistic nylon or Kevlar that can stop a moving chain in milliseconds. I always wear chaps, even for seemingly minor tasks. One slip can have devastating consequences.

Foot Protection

Steel-Toed Boots: Steel-toed boots protect your feet from falling objects and provide a stable platform for operating the chainsaw. Look for boots with good ankle support and slip-resistant soles.
Cut-Resistant Boots: For added protection, consider wearing cut-resistant boots specifically designed for chainsaw use. These boots have layers of cut-resistant material that can protect your feet from accidental contact with the chain.

Additional Safety Gear

First-Aid Kit: Keep a well-stocked first-aid kit readily available in case of injury. Include items such as bandages, antiseptic wipes, gauze pads, and pain relievers.
Communication Device: Carry a cell phone or two-way radio to communicate with others in case of emergency.

Pro Tip 2: Inspect and Maintain Your Chainsaw

Regular inspection and maintenance are essential for ensuring your chainsaw operates safely and efficiently. Neglecting maintenance can lead to poor performance, increased risk of accidents, and premature wear.

Pre-Operation Checklist

Before each use, perform a thorough inspection of your chainsaw:

Chain Condition: Check the chain for sharpness, damage, and proper tension. Sharpen the chain if necessary and replace it if it is worn or damaged. A dull chain requires more force to cut, increasing the risk of kickback.
Bar Condition: Inspect the bar for wear, damage, and proper lubrication. Clean the bar groove and oil holes to ensure adequate oil flow. A worn or damaged bar can cause the chain to derail or bind.
Fuel and Oil Levels: Check the fuel and oil levels and refill as needed. Use the correct fuel-to-oil ratio as specified by the manufacturer. Running the chainsaw with insufficient lubrication can cause serious damage to the engine and bar.
Safety Features: Test the chain brake to ensure it is functioning properly. Check the throttle trigger, on/off switch, and other safety features. A malfunctioning chain brake can render the chainsaw unsafe to operate.
Air Filter: Inspect the air filter and clean or replace it if it is dirty. A clogged air filter can restrict airflow to the engine, reducing power and increasing fuel consumption.

Chain Sharpening

A sharp chain is essential for safe and efficient cutting. Use a chainsaw file or a chain grinder to sharpen the chain regularly.

Filing Angle and Depth: Maintain the correct filing angle and depth as specified by the chain manufacturer. Using the wrong angle or depth can damage the chain and reduce its cutting performance. I use a guide to ensure consistency.
Consistent Sharpening: Sharpen each tooth evenly to maintain a balanced chain. Unevenly sharpened teeth can cause the chainsaw to pull to one side or vibrate excessively.

Bar Maintenance

Bar Cleaning: Clean the bar groove regularly to remove sawdust and debris. Use a bar groove cleaner or a small screwdriver to clear any obstructions.
Bar Dressing: Use a bar dressing tool to remove burrs and smooth the edges of the bar. A damaged bar can cause the chain to derail or bind.
Bar Flipping: Flip the bar periodically to distribute wear evenly. This will prolong the life of the bar and improve its performance.

Chainsaw Lubrication

Proper lubrication is essential for preventing wear and tear on the chain and bar.

Chain Oil Selection: Use a high-quality chain oil specifically designed for chainsaws. Avoid using motor oil or other substitutes, as they may not provide adequate lubrication. I prefer using a biodegradable chain oil to minimize environmental impact.
Oil Flow Adjustment: Adjust the oil flow rate to match the cutting conditions. Increase the oil flow for cutting hardwoods or when operating in hot weather.
Oil Reservoir Check: Check the oil reservoir regularly and refill as needed. Running the chainsaw with insufficient oil can cause the chain and bar to overheat and seize.

Long-Term Storage

If you are storing your chainsaw for an extended period, take the following steps to prevent damage:

Fuel Tank Drain: Drain the fuel tank completely to prevent the fuel from deteriorating and clogging the carburetor.
Chain and Bar Cleaning: Clean the chain and bar thoroughly and apply a coat of oil to prevent rust.
Storage Location: Store the chainsaw in a dry, protected location away from direct sunlight and extreme temperatures.

Pro Tip 3: Assess the Wood and Surroundings

Before making any cuts, carefully assess the wood you are demolishing and the surrounding environment. This will help you identify potential hazards and plan your cuts accordingly.

Wood Inspection

Hidden Objects: Check the wood for nails, screws, staples, and other hidden objects. These objects can damage the chain and cause kickback. I use a metal detector to scan the wood before cutting.
Rot and Decay: Inspect the wood for signs of rot, decay, or insect infestation. Decayed wood can be unstable and unpredictable, increasing the risk of accidents. I once encountered a severely rotted beam that collapsed unexpectedly, nearly causing me to lose my balance.
Stress Points: Identify any stress points or areas where the wood is under tension. Cutting these areas can cause the wood to splinter or collapse unexpectedly.

Environmental Assessment

Clearance: Ensure that there is adequate clearance around the work area. Remove any obstacles that could impede your movement or create a tripping hazard.
Overhead Hazards: Be aware of overhead hazards such as power lines, tree limbs, and unstable structures. Maintain a safe distance from these hazards.
Bystanders: Keep bystanders at a safe distance from the work area. Establish a clear exclusion zone to prevent accidental injuries.
Weather Conditions: Avoid operating the chainsaw in wet or windy conditions. Wet wood can be slippery and difficult to cut, while strong winds can make it difficult to control the chainsaw.

Cutting Plan

Develop a detailed cutting plan before starting any demolition work. This will help you ensure that you are cutting the wood in a safe and controlled manner.

Cutting Sequence: Determine the order in which you will make your cuts. Start with the easiest cuts and progress to the more difficult ones.
Cutting Techniques: Choose the appropriate cutting techniques for each situation. Use bore cuts for relieving tension and plunge cuts for making precise cuts in tight spaces.
Support Structures: Identify any support structures that need to be in place before making certain cuts. Use temporary bracing to support unstable sections of wood.

Pro Tip 4: Master Safe Cutting Techniques

Proper cutting techniques are essential for safe and efficient chainsaw operation. Using the wrong techniques can increase the risk of kickback, loss of control, and injury.

Proper Stance and Grip

Stance: Stand with your feet shoulder-width apart and your weight evenly distributed. Maintain a stable and balanced stance.
Grip: Grip the chainsaw firmly with both hands. Wrap your thumbs around the handles and keep your wrists straight.

Starting the Chainsaw

Ground Start: Place the chainsaw on the ground with the chain brake engaged. Hold the front handle firmly with one hand and pull the starter cord with the other.
Drop Start: If you are unable to start the chainsaw on the ground, you can use a drop start. Hold the chainsaw firmly with one hand and drop it onto the ground, pulling the starter cord as it falls. Be extremely cautious when using this method, as it can be dangerous if not performed correctly. I personally avoid drop starts whenever possible.

Cutting Techniques

Bore Cut: A bore cut is used to relieve tension in the wood before making a final cut. Plunge the tip of the bar into the wood at a slight angle and then pivot the chainsaw to create a slot.
Plunge Cut: A plunge cut is used to make precise cuts in tight spaces. Plunge the tip of the bar directly into the wood and then move the chainsaw forward to create a cut. Be extremely cautious when using this technique, as it can increase the risk of kickback.
Bucking: Bucking is the process of cutting a log into shorter lengths. Use proper bucking techniques to prevent the log from pinching the chain or kicking back.
Felling: Felling is the process of cutting down a tree. Felling trees requires specialized knowledge and experience. If you are not experienced in felling trees, seek professional assistance.

Avoiding Kickback

Kickback is a sudden and violent upward or backward movement of the chainsaw bar. It is a leading cause of chainsaw injuries.

Kickback Zone: Be aware of the kickback zone, which is the upper quadrant of the chainsaw bar tip. Avoid cutting with this area of the bar.
Bore Cuts: Use bore cuts to relieve tension in the wood before making a final cut. This will help prevent the wood from pinching the chain and causing kickback.
Anti-Kickback Features: Use a chainsaw with anti-kickback features such as a chain brake, low-kickback chain, and a bar with a reduced kickback tip.
Proper Technique: Maintain a firm grip on the chainsaw and keep your body out of the path of the chain.

Working with Hazardous Wood

Springpoles: Springpoles are small trees or branches that are bent under tension. Cutting a springpole can cause it to snap back violently, causing serious injury. Use extreme caution when working with springpoles.
Hangers: Hangers are broken or partially detached branches that are suspended in the air. Hangers can fall unexpectedly, causing serious injury. Use extreme caution when working around hangers.

Pro Tip 5: Handle Chainsaw Demolition Challenges

Demolition work presents unique challenges that require specialized techniques and strategies.

Cutting Through Embedded Objects

Metal Detection: Use a metal detector to locate nails, screws, and other metal objects embedded in the wood.
Avoid Cutting: If possible, avoid cutting through embedded objects. Use a pry bar or other tool to remove the object before cutting.
Specialized Chains: Use a chain with carbide-tipped teeth or hardened steel for cutting through wood with embedded objects.

Working in Confined Spaces

Limited Movement: Be aware of your surroundings and avoid making sudden movements.
Short Bar: Use a chainsaw with a shorter bar for better maneuverability.
Plunge Cuts: Use plunge cuts to make precise cuts in tight spaces.

Demolishing Unstable Structures

Support Structures: Use temporary bracing to support unstable sections of the structure.
Cutting Sequence: Plan your cutting sequence carefully to avoid causing the structure to collapse unexpectedly.
Professional Assistance: If you are demolishing a large or complex structure, seek professional assistance.

Handling Dust and Debris

Respiratory Protection: Wear a respirator to protect your lungs from dust and debris.
Dust Control: Use water or other methods to control dust.
