Electric Chainsaw Replacement Chain: Top 5 Tips for Pro Woodcutters
Tip #1: Understanding Your Electric Chainsaw’s Chain Specifications
The first, and most crucial step, is knowing exactly what kind of chain your electric chainsaw needs.
Don’t just guess!
Using the wrong chain can damage your saw, create dangerous kickback situations, and simply not cut effectively.
I remember one time, early in my career, I thought “close enough” was good enough.
I ended up with a chain that was too long for the bar, and it kept jumping off.
A frustrating and potentially dangerous mistake!
Here’s how to get it right:
- Check Your Owner’s Manual: This is your bible.
The manual will list the specific chain type, pitch, gauge, and drive link count required for your particular model.
Don’t skip this step! - Identify the Pitch: The pitch is the distance between any three consecutive rivets on the chain, divided by two.
Common pitches for electric chainsaws are 3/8″ low profile (LP) and .325″.
You can measure this with a pitch gauge, or often find it stamped on the chainsaw’s bar.
I often carry a small multi-tool that includes a pitch gauge, especially when buying chains in bulk. - Determine the Gauge: The gauge is the thickness of the drive links that fit into the guide bar groove.
Common gauges are .043″, .050″, and .058″.
Again, the owner’s manual is your friend here.
You can also use a gauge tool for accurate measurement. - Count the Drive Links: This is the number of drive links (the little teeth that engage with the sprocket) on your old chain.
This is critical for proper fit.
Lay your old chain out straight and count carefully.
If you’ve discarded your old chain, you can often find this information on a sticker on the chainsaw bar, or by consulting the owner’s manual. - Consider the Bar Length: While not directly a chain specification, the bar length dictates the number of drive links needed.
A longer bar requires more drive links.
Why is this important?
Using the wrong chain pitch can damage the sprocket and chain drive mechanism.
Incorrect gauge can cause the chain to bind in the bar groove or, conversely, be too loose and prone to derailing.
The wrong number of drive links will simply prevent the chain from fitting properly on the bar.
Example: Let’s say you have a Greenworks 40V 16-inch electric chainsaw.
The manual might specify a 3/8″ LP pitch, .050″ gauge, and 56 drive links.
Now you know exactly what to look for.
Tip #2: Choosing the Right Chain Type for the Job
Not all chainsaw chains are created equal.
There are several different types, each designed for specific cutting applications.
Selecting the right chain type can significantly improve your cutting speed, efficiency, and the overall lifespan of your chainsaw.
- Full Chisel Chains: These chains have square-cornered teeth that cut aggressively and quickly.
They are ideal for felling clean, softwood trees like pine and fir.
However, they are more prone to dulling quickly if they come into contact with dirt, rocks, or hard, dry wood. - Semi-Chisel Chains: These chains have rounded corners on the teeth, making them more durable and less susceptible to dulling.
They are a good all-around choice for general firewood cutting and handling harder wood like oak or maple.
I generally prefer semi-chisel chains for most of my firewood processing. - Low-Profile (LP) Chains: These chains are designed for smaller, lower-powered chainsaws, including many electric models.
They have a smaller cutter and a shallower depth gauge, which reduces kickback potential.
They are ideal for pruning, limbing, and light-duty cutting. - Ripping Chains: These chains are specifically designed for cutting wood with the grain, rather than across it.
They have a unique tooth geometry that produces smooth, even cuts, ideal for milling lumber.
While less common for general firewood work, they are invaluable if you’re planning on using your chainsaw for any milling applications.
Chain Material and Construction:
- Chrome Plating: Most chainsaw chains are chrome-plated for increased wear resistance and durability.
Look for chains with a high-quality chrome plating for longer lifespan. - Hardened Steel: The teeth of a chainsaw chain are made from hardened steel to maintain their sharpness and cutting ability.
Higher quality chains use a higher grade of steel, which will hold an edge longer.
My Personal Experience: I once tried to use a full chisel chain to cut through some old, dry oak logs.
The chain dulled almost instantly, and I ended up spending more time sharpening than cutting.
Switching to a semi-chisel chain made a world of difference.
The rounded teeth were much more resistant to the abrasive nature of the dry wood, and I was able to cut through the logs with ease.
Data Insight: In my firewood business, I’ve tracked chain lifespan for different wood types.
Full chisel chains average about 10 hours of cutting time in softwood before needing sharpening, while semi-chisel chains can last up to 15 hours in hardwood.
Choosing the Right Chain – A Flowchart:
- What type of wood are you cutting?
- Softwood (pine, fir): Full Chisel or Semi-Chisel
- Hardwood (oak, maple): Semi-Chisel
- Dry/Dirty Wood: Semi-Chisel
- What is the size and power of your chainsaw?
- Smaller Electric Chainsaw: Low-Profile
- Larger Electric Chainsaw: Full Chisel or Semi-Chisel
- Are you cutting with the grain (milling)?
- Yes: Ripping Chain
- No: Proceed to Step 1
Tip #3: Mastering Chain Sharpening and Maintenance
A sharp chain is a safe chain.
A dull chain requires more force to cut, increasing the risk of kickback and putting unnecessary strain on your chainsaw’s motor.
Regular sharpening and maintenance are essential for optimal performance and safety.
- Sharpening Frequency: How often you need to sharpen your chain depends on the type of wood you’re cutting and how often you use your chainsaw.
As a general rule, sharpen your chain every time you refuel your chainsaw (if gasoline-powered) or after every few hours of use for electric models.
You’ll know your chain needs sharpening when it starts producing sawdust instead of chips, requires more force to cut, or pulls to one side. - Sharpening Tools: There are several different tools you can use to sharpen your chainsaw chain:
- Round File and File Guide: This is the most common and affordable method.
Use a round file of the correct diameter for your chain’s pitch, along with a file guide to maintain the correct angle and depth.
I find this method gives me the most control and precision. - Electric Chain Sharpener: These sharpeners use a grinding wheel to quickly and easily sharpen the chain.
They are more expensive than a file and guide but can save you a lot of time, especially if you have a lot of chains to sharpen. - Chainsaw Sharpening Attachment: Some chainsaw manufacturers offer sharpening attachments that mount directly onto the chainsaw.
These can be convenient but are often less precise than other methods.
- Round File and File Guide: This is the most common and affordable method.
- Sharpening Technique:
- Secure the Chain: Secure the chainsaw in a vise or clamp to prevent it from moving while you’re sharpening.
- Identify the Cutting Angle: Refer to your chainsaw’s manual or the chain manufacturer’s specifications for the correct cutting angle.
- File Each Tooth: Using the round file and file guide, file each tooth from the inside out, following the existing angle.
Apply gentle, consistent pressure.
Aim for 3-5 strokes per tooth. - Maintain Depth Gauges: The depth gauges (the small projections in front of each cutter) control how much wood each tooth can bite.
Use a flat file and depth gauge tool to maintain the correct depth gauge setting. - Check for Uniformity: Ensure that all the teeth are sharpened to the same length and angle.
This is crucial for smooth and even cutting.
- Chain Maintenance:
- Cleaning: Regularly clean your chainsaw chain with a brush and solvent to remove sawdust, pitch, and debris.
- Lubrication: Keep your chain properly lubricated with chainsaw bar and chain oil.
This reduces friction, prolongs chain life, and prevents overheating. - Tensioning: Regularly check and adjust the chain tension.
A properly tensioned chain should be snug against the bar but still able to be pulled around by hand. - Inspection: Regularly inspect your chain for damage, such as cracks, broken teeth, or loose rivets.
Replace the chain if you find any significant damage.
Case Study: The Power of a Sharp Chain
I once had a contract to clear a large area of overgrown brush and small trees.
I started the job with a relatively new, but not particularly sharp, chain.
It was slow going, and I was constantly fighting the saw to keep it from binding.
After a few hours, I took the time to properly sharpen the chain.
The difference was night and day!
The chainsaw sliced through the brush with ease, and I was able to complete the job in half the time.
This experience taught me the importance of prioritizing chain sharpness.
Measurement Matters: The correct round file size is crucial.
A 3/8″ LP chain typically requires a 5/32″ round file, while a .325″ chain needs a 3/16″ round file.
Always consult your chainsaw’s manual or the chain manufacturer’s specifications.
Tip #4: Understanding Chain Tension and Lubrication for Electric Chainsaws
Proper chain tension and lubrication are critical for the performance and longevity of your electric chainsaw.
They work together to reduce friction, prevent overheating, and ensure smooth, efficient cutting.
- Chain Tension:
- Why is it important? Incorrect chain tension can lead to several problems.
If the chain is too loose, it can derail from the bar, causing damage to the chainsaw and potentially injuring the operator.
If the chain is too tight, it can overheat, bind, and put excessive strain on the motor and bar. - How to Check Chain Tension:
- Turn off the chainsaw and disconnect the power source. Safety first!
- Wear gloves. The chain can be sharp, even when not running.
- Lift the tip of the bar upwards. The chain should be snug against the bottom of the bar.
- Pull the chain around the bar by hand. It should move freely without binding.
- Check the drive link protrusion. The drive links should protrude slightly from the bar groove.
- How to Adjust Chain Tension:
- Locate the chain tensioning mechanism. This is usually a screw or knob located on the side of the chainsaw, near the bar.
- Loosen the bar retaining nuts. This allows you to adjust the bar position.
- Adjust the tensioning screw or knob. Turning it clockwise tightens the chain, while turning it counterclockwise loosens it.
- Tighten the bar retaining nuts. Ensure the bar is securely fastened.
- Recheck the chain tension. It should be snug but still able to be pulled around by hand.
- Why is it important? Incorrect chain tension can lead to several problems.
- Chain Lubrication:
- Why is it important? Chain lubrication reduces friction between the chain and the bar, preventing overheating and wear.
It also helps to flush away sawdust and debris, keeping the chain clean and sharp. - Choosing the Right Lubricant: Use a high-quality chainsaw bar and chain oil specifically designed for chainsaws.
Avoid using motor oil or other lubricants, as they may not provide adequate lubrication and can damage the chainsaw.
I prefer using vegetable-based bar and chain oil, as it is more environmentally friendly. - How to Lubricate the Chain:
- Check the oil reservoir level. Most electric chainsaws have a transparent oil reservoir, allowing you to easily check the level.
- Fill the reservoir with bar and chain oil. Be careful not to overfill.
- Ensure the oiler is functioning properly. The oiler should automatically lubricate the chain while the chainsaw is running.
You can usually test the oiler by holding the chainsaw over a piece of cardboard and running it briefly.
Oil should be sprayed onto the cardboard. - Regularly check the chain for lubrication. If the chain appears dry or is producing excessive smoke, stop cutting and check the oil reservoir and oiler.
- Why is it important? Chain lubrication reduces friction between the chain and the bar, preventing overheating and wear.
Personalized Story: I once neglected to check the oil reservoir on my electric chainsaw, and the chain ran dry.
The chain quickly overheated, and the bar started to smoke.
I caught it just in time, but the chain was damaged and needed to be replaced.
This experience taught me the importance of regularly checking and maintaining the chain lubrication.
Data Point: A properly lubricated chainsaw chain can last up to 50% longer than a chain that is run dry.
Troubleshooting Lubrication Issues:
- No oil flow: Check the oil reservoir level, the oiler filter, and the oiler pump.
The filter may be clogged, or the pump may be damaged. - Insufficient oil flow: Adjust the oiler flow rate, if possible.
Some chainsaws have an adjustable oiler. - Oil leaking: Check the oil reservoir cap and the oiler pump for leaks.
Tip #5: Safety First: Kickback Prevention and Personal Protective Equipment (PPE)
Chainsaw operation is inherently dangerous, and kickback is one of the most common causes of chainsaw-related injuries.
Understanding kickback and taking steps to prevent it is essential for safe chainsaw operation.
In addition to kickback prevention, wearing appropriate personal protective equipment (PPE) is crucial for protecting yourself from injury.
- What is Kickback? Kickback occurs when the upper quadrant of the chainsaw bar (the “kickback zone”) comes into contact with a solid object.
This can cause the chainsaw to suddenly and violently thrust upwards and backwards towards the operator. - Causes of Kickback:
- Contact with the kickback zone: This is the most common cause of kickback.
- Pinching the chain: If the chain becomes pinched in the cut, it can cause the chainsaw to kick back.
- Dull chain: A dull chain requires more force to cut, increasing the risk of kickback.
- Cutting above shoulder height: This puts the operator in a vulnerable position and increases the risk of kickback.
- Kickback Prevention Techniques:
- Understand the kickback zone: Be aware of the location of the kickback zone on your chainsaw bar and avoid contacting it with solid objects.
- Use a chainsaw with a chain brake: A chain brake is a safety device that stops the chain instantly in the event of kickback.
- Maintain a sharp chain: A sharp chain cuts more efficiently and reduces the risk of kickback.
- Hold the chainsaw firmly with both hands: This gives you better control of the chainsaw and reduces the risk of kickback.
- Keep your thumbs wrapped around the handles: This provides a secure grip and prevents your hands from being thrown off the chainsaw in the event of kickback.
- Stand to the side of the cut: This keeps you out of the direct line of kickback.
- Avoid cutting above shoulder height: This puts you in a vulnerable position and increases the risk of kickback.
- Be aware of your surroundings: Watch out for branches, rocks, and other obstacles that could cause kickback.
- Personal Protective Equipment (PPE):
- Eye protection: Wear safety glasses or a face shield to protect your eyes from flying debris.
- Hearing protection: Wear earplugs or earmuffs to protect your hearing from the loud noise of the chainsaw.
- Head protection: Wear a hard hat to protect your head from falling branches and other hazards.
- Hand protection: Wear heavy-duty work gloves to protect your hands from cuts, abrasions, and vibration.
- Leg protection: Wear chainsaw chaps or chainsaw-resistant pants to protect your legs from cuts.
- Foot protection: Wear steel-toed boots with good ankle support to protect your feet and ankles.
Statistics: According to the Consumer Product Safety Commission (CPSC), there are approximately 30,000 chainsaw-related injuries in the United States each year.
Many of these injuries could be prevented by following safe operating procedures and wearing appropriate PPE.
Real-World Example: I once witnessed a fellow woodcutter experience a severe kickback while felling a tree.
He was lucky to be wearing chainsaw chaps, which prevented a serious leg injury.
This incident reinforced the importance of wearing appropriate PPE at all times.
Strategic Insight: Investing in high-quality PPE is an investment in your safety and well-being.
Don’t skimp on PPE – it could save your life.
Beyond the Basics: Advanced Safety Techniques:
- Reactive Forces Awareness: Understand that chainsaws produce reactive forces.
Be prepared for the saw to push, pull, or twist as you cut. - Boring Cuts (Plunge Cuts): These are inherently risky and require advanced skill.
Only perform boring cuts if you are properly trained and experienced. - Felling Techniques: Learn proper felling techniques to control the direction of the falling tree and minimize the risk of accidents.
By following these five tips, you can ensure that your electric chainsaw operates at peak performance, maximizing your efficiency and safety.
Remember, a well-maintained chainsaw is a safe and productive tool.
