Choosing the Right Chainsaw: A Look at Chainsaw Types

Before you even think about starting a chainsaw, it’s crucial to select the right tool for the job. Chainsaws come in various types, each designed for specific tasks and power needs.

Gas-Powered Chainsaws

Gas-powered chainsaws are the most common and powerful type. They run on a mixture of gasoline and oil and are ideal for heavy-duty tasks like felling large trees, clearing dense brush, and chopping firewood.

Pros: High power, long run time (limited only by fuel), excellent for tough jobs.
Cons: Noisier, produce exhaust fumes, require fuel mixing and more complex maintenance.

Electric Chainsaws (Corded)

Corded electric chainsaws offer a good balance of power and convenience for lighter tasks around the yard. They plug into a standard outlet, so your work is limited by the cord’s length.

Pros: Lightweight, quiet, no fumes, easy to start, less maintenance.
Cons: Limited by power outlet, cord can be a safety hazard, less powerful than gas models.

Battery-Powered Chainsaws

Battery-powered chainsaws are becoming increasingly popular due to their portability and ease of use. They run on rechargeable batteries, offering a good compromise between gas and corded electric models for medium-duty tasks.

Pros: Portable, quiet, no fumes, easy to start, relatively low maintenance.
Cons: Limited by battery life, battery recharge time, generally less powerful than gas models for extended heavy use.

Pole Saws

While not strictly chainsaws in the traditional sense, pole saws are essential for trimming branches from trees. They feature a chainsaw bar and chain mounted on a long pole, allowing you to reach high places safely.

Pros: Excellent for reaching high branches, keeps you further from falling debris.
Cons: Can be heavy and difficult to maneuver, limited cutting capacity.

Chainsaw Safety: Your Top Priority

Chainsaw safety is paramount. Operating a chainsaw without proper precautions can lead to serious injury.

Personal Protective Equipment (PPE)

Always wear appropriate PPE before operating a chainsaw. This gear protects you from flying debris, cuts, and noise.

Helmet: Protects your head from falling branches and impacts. Look for one with a face shield and ear protection.
Eye Protection: Safety glasses or goggles are essential to prevent debris from entering your eyes. A face shield offers additional protection.
Hearing Protection: Chainsaws are loud. Earplugs or earmuffs are crucial to prevent hearing damage.
Gloves: Heavy-duty, non-slip gloves provide a better grip and protect your hands.
Chainsaw Chaps/Trousers: These are made of special material designed to stop a moving chain on contact, preventing severe leg injuries.
Chainsaw Boots: Steel-toed boots with cut-resistant material offer protection for your feet and ankles.

Safe Operating Practices

Read the Manual: Familiarize yourself with your specific chainsaw model.
Clear the Work Area: Remove any obstacles, debris, or tripping hazards around the cutting area. Ensure no one else is within 30 feet of your operating zone.
Proper Stance: Stand with your feet shoulder-width apart, knees slightly bent. Maintain a firm grip on both handlebars with your thumbs wrapped around them.
Never Cut Above Shoulder Height: This is extremely dangerous and can lead to loss of control.
Beware of Kickback: Kickback is a sudden, violent upward and backward motion of the chainsaw. It occurs when the nose of the guide bar touches an object or when the wood closes in and pinches the chain in the cut. Always keep the chain brake engaged when not cutting, and avoid cutting with the tip of the bar.
Maintain Control: Keep a firm grip on the chainsaw at all times. Don’t overreach.
Shut Down When Moving: Always turn off the chainsaw and engage the chain brake when walking or moving more than a few steps.
Don’t Operate When Tired: Fatigue can lead to mistakes and accidents.
Never Operate Alone: It’s best to have someone nearby in case of an emergency.
Fueling Safely: Fuel your chainsaw outdoors on a clear, flat surface away from any open flames or sparks. Let the engine cool before refueling.

Chainsaw Maintenance: Keeping Your Tool in Top Shape

Regular chainsaw maintenance is vital for performance, longevity, and safety. A well-maintained saw is a safer saw.

Basic Maintenance Checks

Before each use, perform these quick checks:

Chain Tension: The chain should be snug but still able to be pulled by hand. It shouldn’t sag.
Bar Oil Level: Ensure the oil reservoir is full.
Air Filter: Check for dirt and clean or replace as needed.
Spark Plug: Ensure it’s clean and properly gapped.
Fasteners: Check that all screws and bolts are tight.
Chain Brake: Test that the chain brake functions correctly.

Chainsaw Sharpening: The Key to Efficiency

A dull chainsaw chain is inefficient, dangerous, and can damage your saw. Chainsaw sharpening should be done regularly, ideally after every few hours of use.

How to Sharpen Your Chainsaw Chain

Gather Supplies: You’ll need a round file of the correct size for your chain (check your manual), a file guide, a flat file or bench grinder for the rakers, and a vise to hold the bar.
Secure the Chainsaw: Clamp the guide bar firmly in a vise. Engage the chain brake.
Identify the Cutter: Find the shortest cutter to use as your guide for the depth of sharpening.
File the Cutters:
- Place the file in the file guide.
- Position the file at the correct angle (usually 25-35 degrees, check your manual) against the cutter.
- File with smooth, even strokes from the inside of the tooth to the outside. Apply firm pressure on the forward stroke and lift on the backward stroke.
- Sharpen each cutter on one side, then move to the other side of the chain and sharpen the remaining cutters.
File the Rakers: The rakers (or depth gauges) are small teeth in front of the cutters. They control how much wood the cutter removes. Use a flat file to lower the rakers so they are slightly below the cutting tooth. Follow the instructions in your manual for the correct depth.
Check Chain Tension: After sharpening, re-check and adjust chain tension.

How to Sharpen a Chainsaw Chain with a Grinder

Using a bench grinder or specialized chainsaw sharpening grinder can be faster and more consistent, but requires more care to avoid overheating the chain. Follow the grinder’s instructions precisely and use cooling fluid if recommended.

Chainsaw Operation: Mastering the Techniques

Proper chainsaw operation involves more than just pulling the trigger. It requires technique and awareness.

Chainsaw Starting: Getting the Engine Running

There are a few common methods for chainsaw starting, depending on the model. Always ensure the chain brake is engaged before attempting to start.

Cold Start Procedure (Gas Chainsaws)

Place on Ground: Set the chainsaw on a clear, flat surface.
Engage Chain Brake: Push the chain brake lever forward.
Choke Setting:
- If the engine is cold, move the choke lever to the “cold start” or fully closed position.
- If the engine is warm, move the choke to the “warm start” or half-choked position.
Primer Bulb: If your chainsaw has a primer bulb, press it several times until you see fuel enter the bulb.
Throttle Lock: If present, engage the throttle lock (usually a small lever or button that holds the throttle slightly open).
Pull the Starter Rope: Hold the chainsaw firmly with one foot on the rear handle or secure it to the ground. Pull the starter rope with a smooth, firm motion until you feel resistance, then give it a short, sharp pull. You should hear the engine sputter.
Adjust Choke: Once the engine sputters, move the choke to the “warm start” or half-open position. Pull the starter rope again.
Start the Engine: When the engine fires up, immediately move the choke to the “run” or fully open position.
Disengage Chain Brake: Once the engine is running smoothly, disengage the chain brake.
Warm-up: Allow the engine to warm up for a minute or two before cutting.

Battery-Powered Chainsaw Starting

Battery-powered chainsaws are simpler. Typically, you just insert a charged battery and press the power button and trigger simultaneously. Always ensure the chain brake is engaged before battery insertion.

Chainsaw Cutting Techniques: Precision and Safety

Effective chainsaw cutting techniques maximize efficiency and minimize risk.

Basic Cutting Principles

Let the Saw Do the Work: Don’t force the saw. Apply gentle pressure and let the chain’s speed do the cutting.
Maintain a Firm Grip: Keep both hands on the handlebars, thumbs wrapped around them for maximum control.
Support the Saw: Whenever possible, support the weight of the chainsaw on the wood or a stable surface to reduce fatigue and improve control.
Cut at Full Throttle: Operate the chainsaw at full throttle for efficient cutting and to prevent chain stalling.

Bucking (Cutting a Log into Sections)

Bucking is cutting a felled tree or log into shorter lengths.

Cutting from Above (Top Bucking): For logs supported at both ends, start cutting from the top. Be aware of tension in the wood that might pinch the bar.
Cutting from Below (Bottom Bucking): If the log is supported on one end, start by cutting from the underside to relieve tension, then finish from the top. This prevents the log from pinching the bar.
Balanced Cuts: For logs supported in the middle, make a shallow cut from the top (about one-third through), then finish by cutting from the bottom to meet the first cut. This prevents the log from snapping under its own weight and pinching the bar.

Limbing (Removing Branches from a Felled Tree)

Work from the Base Up: Start limbing from the base of the felled tree and work your way up.
Cut Branches from the Top: Generally, cut branches from the top.
Support the Bar: If a branch is under tension, cut from the underside first to relieve the pressure, then finish from the top.
Beware of Spring Poles: These are branches under tension that can spring back violently when cut. Approach them with extreme caution and consider cutting them in stages.

Felling (Cutting Down a Standing Tree)

Felling a tree is the most dangerous chainsaw operation. It requires experience, skill, and careful planning. It is highly recommended that novices do not attempt to fell trees. If you must fell a tree, consider taking a professional course or hiring an experienced arborist.

Assess the Tree: Check the tree’s lean, wind direction, and the surrounding area for potential hazards (buildings, power lines, other trees).
Plan the Fall: Determine the direction you want the tree to fall.
Clear the Escape Route: Create a clear path for yourself to retreat once the tree begins to fall.
Make the Notch Cut: Cut a “V” shaped notch on the side facing the desired fall direction. This notch should be about one-quarter to one-third of the tree’s diameter.
Make the Back Cut: Cut from the opposite side of the tree, slightly above the bottom of the notch. Leave a “hinge” of wood (about one-tenth of the tree’s diameter) between the notch and the back cut. This hinge controls the direction of the fall.
Use Wedges: As you make the back cut, you can insert felling wedges to help control the fall and prevent the bar from getting stuck.
Retreat: Once the back cut is deep enough, the tree should begin to fall. Immediately disengage the chain brake and retreat along your escape route.

Chainsaw Fuel Mix: The Right Blend for Your Engine

For gas-powered chainsaws, using the correct chainsaw fuel mix is essential for engine performance and longevity.

Fuel Mix Ratio

Most modern chainsaws use a 50:1 fuel-to-oil ratio. This means for every 50 parts of gasoline, you add 1 part of high-quality, 2-stroke engine oil specifically designed for air-cooled engines.

Gasoline: Use fresh, unleaded gasoline with an octane rating of 87 or higher. Avoid ethanol-blended fuels if possible, as they can degrade fuel system components over time.
Two-Stroke Oil: Always use a high-quality, air-cooled 2-stroke engine oil. These oils contain special additives to lubricate the engine and prevent carbon buildup. Do not use automotive motor oil.

Mixing Fuel

Use a Clean Container: Always use a clean, approved fuel container for mixing.
Measure Accurately: Measure the gasoline and oil separately.
Add Oil First: Pour the correct amount of oil into the container.
Add Gasoline: Add the gasoline to the container.
Shake Well: Seal the container and shake it thoroughly to ensure the oil and gas are completely mixed.
Label the Container: Clearly label the container with the mixture ratio and date.

Storing Fuel Mix

Store fuel mix in a cool, dry place, out of direct sunlight. Use it within 30 days for best results. Old fuel mix can cause starting problems and damage the engine.

Chainsaw Troubleshooting: Common Issues and Solutions

Sometimes, even with proper maintenance, you might encounter issues. Here are some common chainsaw troubleshooting tips.

Problem	Possible Cause	Solution
Chainsaw won’t start	No fuel, incorrect fuel mix, or old fuel.	Check fuel level. Ensure you’re using the correct 50:1 fuel mix. If fuel is old, drain and refill with fresh mix.
	Spark plug is fouled or wet.	Remove spark plug, clean with a wire brush, and check gap. If wet with fuel, dry it thoroughly and try starting again.
	Air filter is clogged.	Remove and clean the air filter. If it’s damaged, replace it.
	Ignition system issue.	Check spark plug wire connection. If the plug sparks when grounded but the saw still won’t start, there might be an ignition module problem (professional repair may be needed).
	Carburetor is dirty or out of adjustment.	The carburetor may need cleaning or adjustment. This can be tricky, so consider professional service.
Chain not cutting well	Chain is dull.	Sharpen the chain.
	Chain tension is too loose.	Adjust chain tension so it’s snug but can still be pulled by hand.
	Bar or chain is damaged.	Inspect the guide bar for wear or damage, and the chain for broken teeth or stretched links. Replace if necessary.
Chain slows down or stalls	Forcing the saw; dull chain; or saw isn’t powerful enough.	Let the saw cut at its own pace. Sharpen the chain. Ensure you’re using a saw appropriate for the job.
	Blockage in the carburetor or fuel system.	Clean the fuel filter and carburetor.
	Overheating engine.	Ensure the air filter is clean and the cooling fins on the engine are free of debris. Allow the saw to cool down.
Chainsaw leaks oil	Overtightened oil cap, or damaged oil tank.	Ensure the oil cap is snug but not overtightened. Inspect the oil tank for cracks or damage.
	Chain brake engaging slightly.	Check that the chain brake isn’t partially engaged, which can cause oil to be pumped out.
Excessive vibration	Dull chain, improperly sharpened chain, or loose parts.	Sharpen the chain evenly. Check chain tension. Ensure all screws and bolts are tight.
