Ah, the smell of sawdust and two-stroke exhaust! It takes me back to my grandpa’s woodlot, a place where the air always hummed with the song of a well-tuned chainsaw. He taught me everything I know about felling trees, bucking logs, and splitting firewood. I can still picture him, his weathered hands guiding mine as we wrestled a stubborn oak round onto the splitter. Those were the days. This isn’t just a review; it’s about getting the most out of a serious piece of machinery. These are my personal “pro tips” refined over years of cutting wood.

Husqvarna 543XP Chainsaw Review: 5 Pro Tips for Woodcutters

The Husqvarna 543XP is a professional-grade chainsaw designed for demanding tasks. It’s a popular choice for those who need a reliable and powerful tool for felling, limbing, and bucking. Over the years, I’ve put this saw through its paces in various conditions, from hardwoods like oak and maple to softer woods like pine and fir. Here’s my take on it, along with some tips to help you maximize its performance and longevity.

1. Mastering the Art of Proper Chain Tension

Chain tension is the unsung hero of chainsaw performance. Too loose, and the chain can derail, causing damage to the bar, the chain, and potentially, you. Too tight, and you’ll experience excessive wear on the bar, chain, and even the engine. I’ve seen firsthand the consequences of neglecting this crucial aspect.

Why it Matters:

Safety: A loose chain can jump off the bar and cause serious injury. A tight chain can break and whip around.
Performance: Proper tension allows the chain to cut efficiently, reducing strain on the engine and increasing cutting speed.
Longevity: Maintaining correct tension minimizes wear and tear on the bar, chain, and sprocket.

The Sweet Spot:

The ideal chain tension is when the chain can be pulled away from the bar about 1/8 inch (3mm) at the midpoint of the bar. When you pull the chain away from the bar, you should still see the drive links.

How to Adjust:

Safety First: Always wear gloves and ensure the chainsaw is turned off and the chain brake is engaged.
Locate the Tensioning Screw: On the Husqvarna 543XP, the tensioning screw is located on the side of the saw, near the bar.
Loosen the Bar Nuts: Use the provided wrench to slightly loosen the bar nuts. This allows the bar to move freely.
Adjust the Tension: Use a screwdriver to turn the tensioning screw. Turn it clockwise to tighten the chain and counterclockwise to loosen it.
Check the Tension: Pull the chain away from the bar at the midpoint. Adjust until you achieve the desired 1/8 inch (3mm) gap.
Tighten the Bar Nuts: Once the tension is correct, tighten the bar nuts securely.
Test the Chain: Rotate the chain manually to ensure it moves smoothly around the bar.

My Experience:

I once ruined a perfectly good chain and bar by neglecting to check the tension regularly. I was cutting through some dense oak when the chain suddenly derailed and snapped. The bar was also damaged beyond repair. Since then, I’ve made it a habit to check the chain tension every time I refuel. I set a timer on my phone as a reminder. It’s a small investment of time that can save you a lot of money and frustration in the long run.

Key Takeaway:

Regularly checking and adjusting your chain tension is crucial for safety, performance, and longevity. Make it a habit to check it every time you refuel.

2. The Secret to Sharp Chains: Filing Like a Pro

A sharp chain is essential for efficient and safe cutting. A dull chain forces you to apply more pressure, which increases the risk of kickback and puts unnecessary strain on the saw. I can’t stress enough how much easier and safer it is to work with a sharp chain.

Why Sharpness Matters:

Safety: A sharp chain bites into the wood effortlessly, reducing the risk of kickback.
Efficiency: A sharp chain cuts faster and requires less effort, saving you time and energy.
Saw Health: A dull chain forces the engine to work harder, leading to increased wear and tear.

The Anatomy of a Chainsaw Tooth:

Before you start filing, it’s important to understand the different parts of a chainsaw tooth:

Top Plate: The cutting edge of the tooth.
Side Plate: The side of the tooth that also contributes to the cut.
Depth Gauge (Raker): The small projection in front of the cutting edge that controls the depth of the cut.

The Filing Process:

Gather Your Tools: You’ll need a round file (typically 5/32 inch or 4.0mm for the Husqvarna 543XP), a flat file, a depth gauge tool, and a filing vise.
Secure the Saw: Clamp the chainsaw bar in a filing vise to keep it steady.
File the Cutters: Using the round file, file each cutter at the correct angle (typically 30 degrees for the Husqvarna 543XP). Maintain a consistent angle and depth for each tooth. The file should be positioned so that it is slightly angled upwards. I usually use a file guide to keep the angle consistent.
File the Depth Gauges: Use the flat file and depth gauge tool to file the depth gauges to the correct height. The depth gauge should be slightly lower than the cutting edge. The exact height will depend on the type of wood you are cutting. Softer woods require a slightly lower depth gauge.
Check Your Work: After filing, check the sharpness of each tooth. They should be uniformly sharp and have a consistent angle.
Rotate the Saw: Rotate the saw in the vise and repeat the process for the remaining teeth.

My Personal Filing Routine:

I sharpen my chain after every two tanks of fuel. It might seem excessive, but I find that it keeps the chain in optimal condition and makes cutting much easier. I also use a chainsaw chain sharpener occasionally to ensure that the teeth are filed to the exact specifications.

Common Mistakes to Avoid:

Filing at the Wrong Angle: This can ruin the cutting edge and make the chain cut poorly.
Filing Too Deep: This can weaken the tooth and make it more prone to breaking.
Ignoring the Depth Gauges: If the depth gauges are too high, the chain will not cut effectively.

Key Takeaway:

Mastering the art of chain filing is essential for safety, efficiency, and saw health. Invest in the right tools and take the time to learn the proper technique. A sharp chain is a happy chain!

3. Fueling the Beast: The Right Mix and Maintenance

The Husqvarna 543XP is a two-stroke engine, which means it requires a specific fuel mixture of gasoline and oil. Using the wrong fuel mixture can damage the engine and shorten its lifespan. I learned this the hard way when I accidentally used straight gasoline in my grandpa’s old chainsaw. The engine seized up within minutes, and it cost a fortune to repair.

The Importance of the Correct Fuel Mixture:

Lubrication: The oil in the fuel mixture lubricates the engine’s internal components, preventing wear and tear.
Cooling: The fuel mixture also helps to cool the engine, preventing overheating.
Performance: The correct fuel mixture ensures optimal engine performance and fuel efficiency.

The Recommended Fuel Mixture:

The Husqvarna 543XP requires a fuel mixture of 50:1 (gasoline to oil). This means that for every 50 parts of gasoline, you need 1 part of oil. I always use high-quality, synthetic two-stroke oil specifically designed for air-cooled engines.

Mixing the Fuel:

Use a Clean Container: Always use a clean container that is specifically designed for mixing fuel.
Add the Oil First: Pour the correct amount of two-stroke oil into the container.
Add the Gasoline: Add the correct amount of gasoline to the container.
Mix Thoroughly: Shake the container vigorously to ensure that the oil and gasoline are properly mixed.

Fuel Storage:

Use a Proper Container: Store fuel in a tightly sealed, approved fuel container.
Store in a Cool, Dry Place: Store fuel in a cool, dry place away from direct sunlight and heat sources.
Use Fresh Fuel: Gasoline can degrade over time, so it’s important to use fresh fuel. I typically discard any fuel that is more than 30 days old.

Air Filter Maintenance:

A clean air filter is essential for proper engine performance. A dirty air filter restricts airflow, which can lead to reduced power, increased fuel consumption, and engine damage. I clean the air filter on my Husqvarna 543XP after every use.

How to Clean the Air Filter:

Remove the Air Filter Cover: Locate the air filter cover on the chainsaw and remove it.
Remove the Air Filter: Carefully remove the air filter from the housing.
Clean the Air Filter: Use compressed air to blow out any dirt and debris from the air filter. You can also wash the air filter with warm, soapy water. Be sure to let it dry completely before reinstalling it.
Reinstall the Air Filter: Reinstall the air filter into the housing.
Reinstall the Air Filter Cover: Reinstall the air filter cover.

Spark Plug Maintenance:

The spark plug ignites the fuel mixture in the engine. A fouled or worn spark plug can cause starting problems, reduced power, and poor fuel economy. I replace the spark plug on my Husqvarna 543XP every year, or more frequently if I notice any problems.

How to Replace the Spark Plug:

Locate the Spark Plug: The spark plug is located on the top of the engine.
Remove the Spark Plug Wire: Carefully remove the spark plug wire from the spark plug.
Remove the Spark Plug: Use a spark plug wrench to remove the spark plug.
Install the New Spark Plug: Install the new spark plug and tighten it to the correct torque specification.
Reinstall the Spark Plug Wire: Reinstall the spark plug wire onto the spark plug.

Key Takeaway:

Using the correct fuel mixture and performing regular maintenance on the air filter and spark plug are essential for keeping your Husqvarna 543XP running smoothly and efficiently.

4. Bar and Chain Selection: Matching the Tool to the Task

Choosing the right bar and chain for your Husqvarna 543XP is crucial for optimizing performance and safety. Using the wrong combination can lead to inefficient cutting, increased wear and tear, and even dangerous situations like kickback.

Bar Length:

The length of the bar determines the maximum size of the trees you can safely fell and the size of the logs you can buck. The Husqvarna 543XP can accommodate bar lengths ranging from 13 inches to 18 inches.

Shorter Bars (13-16 inches): Ideal for limbing, pruning, and cutting small trees and branches. They are more maneuverable and easier to control.
Longer Bars (18 inches): Better suited for felling larger trees and bucking logs. They provide more reach and cutting capacity.

My Recommendation:

I personally prefer a 16-inch bar for my Husqvarna 543XP. I find it to be a good balance between maneuverability and cutting capacity. It’s long enough to handle most of the trees and logs I encounter, but still short enough to be easy to control during limbing and pruning.

Chain Type:

Chainsaw chains come in various types, each designed for specific cutting applications.

Full Chisel Chains: These chains have square-cornered teeth that are very aggressive and cut quickly. They are best suited for experienced users and clean wood.
Semi-Chisel Chains: These chains have rounded-corner teeth that are more forgiving and less prone to kickback. They are a good choice for general-purpose cutting and dirty wood.
Low-Kickback Chains: These chains are designed with features that reduce the risk of kickback. They are a good choice for beginners and those who are concerned about safety.

Chain Pitch and Gauge:

Pitch: The pitch of a chain is the distance between three rivets divided by two. The Husqvarna 543XP typically uses a chain with a pitch of .325 inches.
Gauge: The gauge of a chain is the thickness of the drive links that fit into the groove of the bar. The Husqvarna 543XP typically uses a chain with a gauge of .050 inches.

Matching Bar and Chain:

It’s essential to use a bar and chain that are compatible with your chainsaw. The bar must be the correct length and have the correct gauge groove. The chain must have the correct pitch and gauge to fit the bar.

My Preferred Combination:

I typically use a 16-inch bar with a semi-chisel chain on my Husqvarna 543XP. I find that this combination provides a good balance of cutting speed, durability, and safety.

Chain Maintenance for Different Wood Types:

Hardwoods (Oak, Maple): Hardwoods are more abrasive than softwoods, so they can dull your chain more quickly. I recommend using a semi-chisel chain and sharpening it frequently.
Softwoods (Pine, Fir): Softwoods are easier to cut than hardwoods, but they can be resinous, which can gum up your chain. I recommend using a full chisel chain and cleaning it regularly.
Dirty Wood: If you are cutting dirty wood, such as logs that have been lying on the ground, I recommend using a semi-chisel chain. The rounded-corner teeth are less prone to damage from dirt and debris.

Key Takeaway:

Choosing the right bar and chain for your Husqvarna 543XP is essential for optimizing performance and safety. Consider the type of cutting you will be doing and the type of wood you will be cutting when selecting your bar and chain.
