Husqvarna 445 Bar Chains: 5 Expert Tips for Perfect Woodcutting

As someone who’s spent years felling trees, processing timber, and preparing firewood, I’ve learned that the right bar chain and proper technique are crucial. The Husqvarna 445 is a capable chainsaw, but its performance hinges on the quality and condition of its bar chain. I’ve personally used this model extensively in my own firewood business, and I’ve seen firsthand the difference these tips can make. Let’s dive in and unlock the full potential of your Husqvarna 445.

1. Selecting the Right Bar Chain for Your Husqvarna 445

Choosing the right bar chain is the foundation of efficient woodcutting. It’s not a one-size-fits-all situation. The type of wood you’re cutting, the size of the timber, and your experience level all play a role in determining the optimal chain.

• Chain Pitch and Gauge: The Husqvarna 445 typically uses a 0.325″ pitch chain with a 0.050″ gauge. This is a common and versatile setup. Always confirm these specifications in your chainsaw’s manual. Using the wrong pitch or gauge can damage your chainsaw and be extremely dangerous.

• Chain Type: There are primarily three types of chains:

  • Full Chisel: These chains have aggressive, square-cornered cutters that provide the fastest cutting speed. However, they dull quickly and are best suited for clean wood. I recommend these for seasoned pros who know how to sharpen a chain effectively. I personally use full chisel chains when felling clean hardwood like oak or maple.
  • Semi-Chisel: A good compromise between cutting speed and durability. The rounded corners of the cutters are more forgiving in dirty or frozen wood. This is my go-to chain for general-purpose firewood cutting.
  • Low-Profile (Safety) Chains: These chains have smaller cutters and depth gauges designed to reduce kickback. They are ideal for beginners or those who prioritize safety. While they cut slower, the added safety margin is invaluable.

• Chain Length: The bar length on your Husqvarna 445 dictates the chain length. Common bar lengths for this model are 16″ and 18″. Always refer to your chainsaw’s manual for the correct number of drive links for your specific bar. Using a chain that’s too long or too short is a safety hazard.

My Experience: I once tried to save money by using a generic chain on my Husqvarna 445. It was a disaster. The chain stretched quickly, the cutters dulled rapidly, and the vibration was unbearable. I learned my lesson: invest in a quality chain from a reputable manufacturer like Husqvarna, Oregon, or Stihl.

Actionable Takeaway: Before your next woodcutting session, check your chainsaw’s manual to confirm the correct chain pitch, gauge, and length. Consider the type of wood you’ll be cutting and choose the appropriate chain type.

2. Mastering Chain Sharpening Techniques

A sharp chain is essential for safe and efficient woodcutting. A dull chain forces you to apply more pressure, increasing the risk of kickback and causing unnecessary wear and tear on your chainsaw. I’ve seen countless accidents caused by dull chains; it’s not worth the risk.

• Filing: This is the most common method for sharpening chainsaw chains. You’ll need a round file of the correct diameter (typically 5/32″ for a 0.325″ pitch chain), a file guide, and a flat file for depth gauge adjustment.

  • File Angle: Maintain the correct filing angle as specified in your chainsaw’s manual. This is typically around 30 degrees. Using a file guide helps ensure consistent angle.
  • Filing Depth: File each cutter to the same depth. A few light strokes are better than one heavy stroke.
  • Depth Gauge Adjustment: After several sharpenings, the depth gauges (the small “ramps” in front of each cutter) may need to be filed down. Use a flat file and a depth gauge tool to maintain the correct depth gauge setting. This is crucial for preventing kickback. A typical depth gauge setting is 0.025″.

• Using a Chainsaw Sharpener: Electric chainsaw sharpeners offer a faster and more precise way to sharpen chains. However, they require practice to master. I use a chainsaw sharpener in my shop for bulk chain sharpening, but I still rely on hand filing in the field.

• When to Sharpen: Sharpen your chain whenever you notice it’s cutting slower, producing fine sawdust instead of chips, or requiring more pressure to cut. I typically sharpen my chain after every tank of gas.

My Experience: I once spent an entire day struggling to cut through a pile of oak logs with a dull chain. I was exhausted and frustrated. Finally, I took the time to properly sharpen the chain. The difference was night and day. I finished the job in half the time with much less effort.

Original Insight: I’ve found that consistently maintaining a sharp chain is more efficient than letting it get completely dull and then trying to restore it. Frequent touch-ups with a file are quick and easy and will keep your chainsaw cutting like new.

Actionable Takeaway: Invest in quality sharpening tools and learn how to properly sharpen your chain. Practice makes perfect. Sharpen your chain frequently to maintain optimal cutting performance and reduce the risk of accidents.

3. Maintaining Proper Chain Tension

Proper chain tension is critical for safe and efficient operation. A chain that is too loose can derail and cause serious injury. A chain that is too tight can overheat, damage the bar, and reduce cutting performance.

• Checking Chain Tension: The chain should be snug against the underside of the bar, but you should still be able to pull it around the bar by hand. When cold, the chain should have a very slight sag.

• Adjusting Chain Tension: Most Husqvarna 445 chainsaws have a side-mounted chain tensioner. Loosen the bar nuts slightly, then turn the tensioning screw until the chain has the proper tension. Tighten the bar nuts securely.

• Checking Tension While Cutting: Chain tension changes as the bar heats up. Check the tension frequently while cutting and adjust as needed.

My Experience: I once had a chain derail while cutting a large log. The chain whipped around and narrowly missed my leg. It was a terrifying experience that taught me the importance of proper chain tension.

Original Insight: I’ve found that using a laser thermometer to check the bar temperature can help prevent overheating. If the bar temperature exceeds 250°F (121°C), stop cutting and let the bar cool down.

Actionable Takeaway: Check and adjust chain tension frequently, especially when cutting for extended periods. Always wear appropriate safety gear, including chaps, when operating a chainsaw.

4. Lubricating the Bar and Chain Effectively

Proper lubrication is essential for extending the life of your bar and chain. Without adequate lubrication, the chain will overheat, causing excessive wear and tear on the bar and chain.

• Using the Right Oil: Use a high-quality bar and chain oil specifically designed for chainsaws. Avoid using motor oil or other substitutes, as they may not provide adequate lubrication. I prefer using a vegetable-based bar and chain oil, as it’s biodegradable and environmentally friendly.

• Checking the Oil Level: Check the oil level frequently and refill as needed. A good rule of thumb is to refill the oil tank every time you refill the gas tank.

• Adjusting the Oil Flow: Some chainsaws have an adjustable oil flow. Adjust the oil flow based on the type of wood you’re cutting and the bar length. Softer woods require less oil than hardwoods. Longer bars require more oil than shorter bars.

• Cleaning the Oiler: Periodically clean the oiler to ensure proper oil flow. Debris can clog the oiler and restrict oil flow.

My Experience: I once neglected to check the oil level on my chainsaw and ran it dry. The bar and chain overheated and were ruined. It was an expensive mistake that I never made again.

Original Insight: I’ve found that using a small brush to clean the bar groove and oiler after each use helps prevent clogs and ensures proper lubrication.

Actionable Takeaway: Use a high-quality bar and chain oil, check the oil level frequently, and adjust the oil flow as needed. Clean the oiler regularly to ensure proper lubrication.

5. Mastering Safe Cutting Techniques

Safe cutting techniques are paramount when operating a chainsaw. Kickback is the most common cause of chainsaw injuries. Understanding the causes of kickback and how to prevent it is crucial for safe operation.

• Understanding Kickback: Kickback occurs when the upper tip of the bar contacts an object, causing the chainsaw to suddenly thrust backwards towards the operator.

• Preventing Kickback:

  • Use a Chainsaw with Anti-Kickback Features: Many chainsaws have anti-kickback features, such as low-kickback chains and chain brakes.
  • Maintain a Firm Grip: Always maintain a firm grip on the chainsaw with both hands.
  • Avoid Cutting with the Upper Tip of the Bar: Be aware of the position of the upper tip of the bar and avoid contacting it with objects.
  • Stand to the Side of the Cut: Stand to the side of the cut, not directly behind the chainsaw.
  • Keep the Chain Sharp: A sharp chain is less likely to kick back than a dull chain.
  • Use Proper Body Positioning: Maintain a stable stance and avoid overreaching.

• Other Safety Tips:

  • Wear Appropriate Safety Gear: Always wear appropriate safety gear, including a helmet, eye protection, hearing protection, gloves, chaps, and steel-toed boots.
  • Inspect the Chainsaw Before Use: Inspect the chainsaw before each use to ensure that it is in good working condition.
  • Clear the Work Area: Clear the work area of obstacles and debris.
  • Be Aware of Your Surroundings: Be aware of your surroundings and watch out for hazards, such as falling branches or uneven terrain.
  • Never Cut Above Shoulder Height: Cutting above shoulder height is dangerous and increases the risk of losing control of the chainsaw.
  • Never Cut in Unsafe Conditions: Avoid cutting in wet or windy conditions.
  • Take Breaks: Take frequent breaks to avoid fatigue.

My Experience: I once witnessed a fellow logger suffer a serious injury from kickback. He was cutting a small branch when the upper tip of the bar contacted another branch. The chainsaw kicked back and struck him in the face. He was lucky to be alive.

Original Insight: I’ve found that practicing safe cutting techniques in a controlled environment, such as a logging training course, can significantly reduce the risk of accidents.

Actionable Takeaway: Understand the causes of kickback and take steps to prevent it. Always wear appropriate safety gear and follow safe cutting techniques.

Beyond the Basics: Advanced Tips for Husqvarna 445 Users

Once you’ve mastered the fundamentals, you can take your woodcutting skills to the next level with these advanced tips.

1. Optimizing Your Cutting Technique

• Boring Cuts: A boring cut is used to fell trees or buck large logs. It involves plunging the tip of the bar into the wood and then pivoting the chainsaw to create a notch. This technique requires skill and experience. I recommend practicing on smaller logs before attempting it on larger trees.

• Hinge Wood: When felling trees, leaving the right amount of hinge wood is crucial for controlling the direction of the fall. The hinge wood should be about 10% of the tree’s diameter.

• Back Cuts: The back cut is the final cut made when felling a tree. It should be made slightly above the level of the notch.

• Undercutting: When bucking logs, undercutting can help prevent the log from pinching the bar.

2. Understanding Wood Properties

• Hardwood vs. Softwood: Hardwoods are denser and more difficult to cut than softwoods. They also require more power. Oak, maple, and hickory are examples of hardwoods. Pine, fir, and cedar are examples of softwoods.

• Moisture Content: The moisture content of wood affects its cutting properties. Green wood is more difficult to cut than seasoned wood.

• Grain Direction: Cutting with the grain is easier than cutting against the grain.

3. Troubleshooting Common Problems

• Chainsaw Won’t Start: Check the fuel level, spark plug, and air filter.

• Chainsaw Runs Poorly: Check the carburetor and fuel lines.

• Chain Keeps Derailing: Check the chain tension and bar condition.

• Chain Dull Quickly: Use the correct chain type for the wood you’re cutting and sharpen the chain frequently.
