Husky 545 Chainsaw Guide: 7 Expert Tips for Woodcutting

The Husqvarna 545 is a fantastic chainsaw, but like any tool, it performs best when properly maintained and used with skill. These seven tips will help you unlock its full potential, improve your cutting efficiency, and extend the life of your saw.

1. Master Chain Maintenance: Sharpening and Tensioning

A sharp chain is paramount for efficient and safe woodcutting. A dull chain requires more force, increases the risk of kickback, and puts unnecessary strain on your saw’s engine. I cannot stress enough the importance of regularly sharpening your chain.

Sharpening Your Chain: A Step-by-Step Guide

1. Gather Your Tools: You’ll need a chainsaw file (typically 5/32″ for the 545), a file guide, a depth gauge tool, and a flat file. I personally prefer using a Pferd chainsaw file kit, as it includes everything you need and ensures consistent sharpening angles.

2. Secure the Saw: Engage the chain brake and secure the saw in a vise or clamp. This will prevent it from moving while you’re sharpening.

3. Identify the Sharpest Cutter: Look for the cutter that is the least damaged. This will be your guide for sharpening the other cutters.

4. File at the Correct Angle: Use the file guide to maintain the correct filing angle. For the Husqvarna 545, this is typically around 30 degrees. Follow the angle markings on your file guide.

5. File Each Cutter Consistently: Use smooth, even strokes, filing from the inside of the cutter to the outside. Count the number of strokes you make on the first cutter and repeat that count for all the other cutters. This ensures consistent sharpness.

6. Check and Adjust Depth Gauges: After sharpening, use the depth gauge tool to check the height of the depth gauges (also known as rakers). These control how much the cutter bites into the wood. If they are too high, the chain will be too aggressive and prone to kickback. If they are too low, the chain will not cut effectively. Use the flat file to carefully lower the depth gauges if necessary. I typically aim for a depth gauge setting of around 0.025″ for hardwood.

7. Rotate the Chain: After sharpening all the cutters on one side of the chain, rotate the saw and repeat the process for the cutters on the other side.

Chain Tensioning: Preventing Problems

Proper chain tension is crucial for safe and efficient cutting. A chain that is too loose can derail, while a chain that is too tight can overheat and damage the bar and sprocket.

1. Check Tension Regularly: Check the chain tension before each use and periodically during cutting.

2. Loosen the Bar Nuts: Use the wrench that came with your chainsaw to loosen the bar nuts.

3. Adjust the Tensioning Screw: Locate the chain tensioning screw on the side of the saw. Turn the screw clockwise to tighten the chain and counterclockwise to loosen it.

4. Check for Proper Tension: The chain should be snug against the bar but still able to be pulled around the bar by hand. You should be able to pull the chain away from the bar about 1/8″ to 1/4″ at the midpoint of the bar.

5. Tighten the Bar Nuts: Once you have achieved the proper tension, tighten the bar nuts securely.

6. Recheck After the First Few Cuts: After making a few cuts, recheck the chain tension. New chains tend to stretch slightly during the initial use.

My Personal Experience: I once neglected to properly tension my chain while felling a large oak. The chain derailed mid-cut, causing the saw to kick back violently. Fortunately, I was able to maintain control of the saw, but it was a close call. This experience reinforced the importance of paying attention to chain tension at all times.

Takeaway: Consistent chain maintenance is the foundation of efficient and safe woodcutting. Sharpen your chain regularly, maintain proper tension, and you’ll significantly improve your cutting performance and reduce the risk of accidents.

2. Fuel and Oil Management: Ensuring Peak Performance

The Husqvarna 545 requires a specific fuel-to-oil ratio for optimal performance and engine longevity. Using the wrong fuel mixture or neglecting to properly lubricate the chain can lead to serious engine damage and premature wear.

Fuel Mixture: The Right Ratio

The Husqvarna 545 requires a fuel mixture of 50:1. This means 50 parts gasoline to 1 part two-stroke oil.

1. Use High-Quality Gasoline: Always use high-quality gasoline with an octane rating of 89 or higher. Avoid using gasoline that contains ethanol, as ethanol can damage the engine.

2. Use Two-Stroke Oil Specifically Designed for Chainsaws: Use a high-quality two-stroke oil specifically designed for chainsaws. Husqvarna XP+ oil is a good choice, as it is formulated to provide excellent lubrication and protection against wear.

3. Mix Fuel and Oil Properly: Use a fuel mixing container to accurately measure the fuel and oil. Pour the oil into the container first, then add the gasoline. Shake the container vigorously to ensure the fuel and oil are thoroughly mixed.

4. Use Fresh Fuel: Fuel can degrade over time, so it’s important to use fresh fuel. Do not use fuel that has been stored for more than 30 days.

My Personal Tip: I always mix a small batch of fuel at a time, enough for a day or two of cutting. This ensures that I’m always using fresh fuel. I also add a fuel stabilizer to the fuel mixture to help prevent it from degrading.

Chain Oil: Keeping the Chain Lubricated

Proper chain lubrication is essential for preventing wear and tear on the chain and bar. A dry chain will generate excessive heat and friction, leading to premature failure.

1. Use Bar and Chain Oil Specifically Designed for Chainsaws: Use a high-quality bar and chain oil specifically designed for chainsaws. Husqvarna bar and chain oil is a good choice, as it is formulated to provide excellent lubrication and protection against wear.

2. Check the Oil Level Regularly: Check the oil level in the oil tank before each use and periodically during cutting.

3. Adjust the Oil Flow Rate: The Husqvarna 545 has an adjustable oil flow rate. Adjust the oil flow rate to match the type of wood you are cutting. For hardwoods, you will need to increase the oil flow rate. For softwoods, you can decrease the oil flow rate.

4. Clean the Oiler Regularly: The oiler can become clogged with sawdust and debris. Clean the oiler regularly to ensure that it is functioning properly.

Case Study: I once worked on a logging project where the crew was using a low-quality bar and chain oil. The chains were wearing out prematurely, and the bars were overheating. After switching to a high-quality bar and chain oil, the chain life increased significantly, and the bar temperatures decreased. This demonstrated the importance of using the right type of oil.

Takeaway: Using the correct fuel mixture and maintaining proper chain lubrication are crucial for maximizing the performance and longevity of your Husqvarna 545. Neglecting these aspects can lead to costly repairs and reduced cutting efficiency.

3. Safe Starting Procedures: Preventing Accidents

Starting a chainsaw can be dangerous if not done correctly. It’s crucial to follow proper starting procedures to prevent accidents and injuries.

Cold Starting: The First Start of the Day

1. Engage the Chain Brake: Always engage the chain brake before starting the saw.

2. Place the Saw on a Firm Surface: Place the saw on a firm, flat surface, such as the ground or a stump. Make sure the chain is not touching anything.

3. Activate the Choke: If the saw is cold, activate the choke. The choke restricts airflow to the engine, making it easier to start.

4. Pull the Starter Cord: Grip the starter handle firmly and pull the starter cord sharply. Do not pull the cord all the way out.

5. Listen for the Engine to “Pop”: After a few pulls, the engine should “pop” or sputter. This indicates that the engine is getting fuel.

6. Disengage the Choke: Once the engine has “popped,” disengage the choke.

7. Pull the Starter Cord Again: Pull the starter cord again to start the engine.

8. Allow the Engine to Warm Up: Allow the engine to warm up for a few minutes before using the saw.

Warm Starting: Restarting a Warm Engine

2. Place the Saw on a Firm Surface: Place the saw on a firm, flat surface, such as the ground or a stump. Make sure the chain is not touching anything.

3. Do Not Activate the Choke: If the engine is warm, do not activate the choke.

4. Pull the Starter Cord: Grip the starter handle firmly and pull the starter cord sharply. Do not pull the cord all the way out.

5. The Engine Should Start Easily: The engine should start easily after a few pulls.

6. Allow the Engine to Warm Up: Allow the engine to warm up for a few seconds before using the saw.

Drop Starting: Never Do It

Never drop start a chainsaw. Drop starting is when you hold the saw in one hand and pull the starter cord with the other. This is extremely dangerous and can lead to serious injury.

My Near Miss: I witnessed a fellow logger attempt a drop start. The saw kicked back, throwing him off balance, and the running chain narrowly missed his leg. This incident solidified my commitment to never drop starting a chainsaw.

Takeaway: Following safe starting procedures is essential for preventing accidents and injuries. Always engage the chain brake, place the saw on a firm surface, and never drop start the saw.

4. Felling Techniques: Precision and Safety

Felling trees is a complex and dangerous task that requires careful planning and execution. Understanding proper felling techniques is crucial for ensuring your safety and the safety of others.

Planning the Fell: Assessing the Tree and Surroundings

1. Assess the Tree: Before felling a tree, carefully assess its size, species, lean, and any defects, such as dead limbs or rot.

2. Assess the Surroundings: Identify any obstacles in the area, such as power lines, buildings, or other trees.

3. Plan Your Escape Route: Plan two escape routes that are clear of obstacles and angled away from the direction of the fall.

4. Determine the Felling Direction: Determine the direction in which you want the tree to fall. This will depend on the tree’s lean, the surrounding obstacles, and the direction of the wind.

Making the Cuts: The Notch and the Back Cut

1. The Notch: The notch is a wedge-shaped cut that is made on the side of the tree in the direction you want it to fall. The notch helps to guide the tree as it falls. The notch should be about 1/5 to 1/3 of the tree’s diameter.

   • The Top Cut: The top cut of the notch should be angled downwards at about 45 degrees.
   • The Bottom Cut: The bottom cut of the notch should be horizontal and meet the top cut at the apex of the notch.

2. The Hinge: The hinge is a strip of uncut wood that is left between the notch and the back cut. The hinge controls the direction of the fall and prevents the tree from kicking back. The hinge should be about 1/10 of the tree’s diameter.

3. The Back Cut: The back cut is made on the opposite side of the tree from the notch. The back cut should be horizontal and level with the bottom of the notch. Leave the hinge intact.

4. Felling Wedges: As you make the back cut, insert felling wedges into the cut to help push the tree over in the desired direction.

The Importance of the Hinge

The hinge is the most critical element in controlling the fall of a tree. It acts as a steering mechanism, guiding the tree as it falls. A properly sized and positioned hinge will ensure that the tree falls in the intended direction.

My Toughest Fell: I once had to fell a large, leaning pine tree in a densely wooded area. The tree was leaning towards a power line, and there was very little room to maneuver. I carefully assessed the situation, planned my cuts precisely, and used felling wedges to guide the tree away from the power line. The tree fell exactly where I wanted it to, without damaging the power line. This experience taught me the importance of careful planning and precise execution when felling trees.

Takeaway: Felling trees is a dangerous task that requires careful planning and execution. Always assess the tree and surroundings, plan your escape routes, and make the cuts precisely. The hinge is the most critical element in controlling the fall of a tree.

5. Limbing and Bucking: Efficient Wood Processing

Once a tree is felled, the next step is to limb and buck it. Limbing involves removing the branches from the trunk, while bucking involves cutting the trunk into shorter lengths.

Limbing: Removing the Branches

1. Work from the Base to the Top: Start limbing at the base of the tree and work your way towards the top. This will prevent you from having to step over branches.

2. Cut on the Opposite Side of the Limb: When cutting a limb, cut on the opposite side of the limb from where you are standing. This will prevent the limb from pinching the saw.

3. Use Proper Stance: Maintain a stable stance and keep your feet firmly planted on the ground.

4. Be Aware of Spring Poles: Be aware of spring poles, which are branches that are bent under tension. These can snap back violently when cut.

Bucking: Cutting the Trunk into Shorter Lengths

1. Measure and Mark the Cuts: Measure and mark the trunk at the desired lengths.

2. Support the Trunk: Support the trunk to prevent it from pinching the saw. You can use logs, rocks, or wedges to support the trunk.

3. Make the Cuts: Make the cuts at the marked locations.

   • Tension: If the trunk is under tension, make a relief cut on the compression side before making the final cut.
   • Compression: If the trunk is under compression, make a relief cut on the tension side before making the final cut.

My Efficiency Hack: I use a chainsaw mill attachment to buck larger logs into boards. This allows me to efficiently process timber into usable lumber. It’s a significant time-saver compared to manual bucking.

Takeaway: Limbing and bucking are essential steps in wood processing. Work safely and efficiently, and be aware of the potential hazards.

6. Chainsaw Safety Gear: Protecting Yourself

Chainsaw work is inherently dangerous, and wearing the proper safety gear is essential for protecting yourself from injury.
