Remanufactured Husqvarna Chainsaw Tips (5 Pro Maintenance Hacks)

It’s a common mistake I see time and again: folks treating their chainsaws like disposable tools. They run them hard, put them away dirty, and then wonder why they sputter, stall, or flat-out fail when they need them most. A remanufactured Husqvarna chainsaw, especially, represents an investment – a chance to own a high-quality tool at a more accessible price point. But that price point means it’s even more critical to maintain it properly. These saws have already lived one life; proper care ensures they live a long and productive second one. That’s why I’m sharing my top 5 pro maintenance hacks for keeping your remanufactured Husqvarna chainsaw roaring. These aren’t just theoretical tips; they’re based on years of experience felling trees, bucking logs, and prepping firewood, both on my own property and helping out friends and neighbors.

5 Pro Maintenance Hacks for Your Remanufactured Husqvarna Chainsaw

1. The Pre-Start Ritual: Beyond Just Pulling the Cord

The pre-start ritual is more than just priming and pulling. It’s a vital check-up that can prevent major headaches down the line. I can’t stress this enough: never start a chainsaw without first performing these checks. I remember one particularly cold morning, rushing to get a dead oak bucked up before a snowstorm. Skipped the pre-start, and ended up with a flooded engine and a very frustrated afternoon. Lesson learned.

• Fuel and Oil Levels: This seems obvious, but it’s crucial. Use the correct fuel mixture (typically 50:1 for Husqvarna, but always check your manual). I prefer using pre-mixed fuel; it eliminates the guesswork and ensures the correct ratio, preventing engine damage. For chain oil, use a high-quality bar and chain oil. I’ve found that vegetable-based oils are environmentally friendly and provide excellent lubrication, especially in colder temperatures. Check the levels and top up as needed before each use.

• Chain Tension: A loose chain is a dangerous chain. It can derail, causing injury or damage to the saw. To check tension, lift the chain in the middle of the bar. You should be able to pull it away from the bar slightly, but not so much that the drive links come out of the bar groove. Adjust the tension using the tensioning screw on the side of the saw. Remember, a chain will loosen as it warms up, so it’s better to start slightly tighter than too loose. I aim for about 1/8″ to 1/4″ of slack when cold.

• Chain Sharpness: A dull chain is inefficient and dangerous. It forces you to push harder, increasing the risk of kickback and putting unnecessary strain on the saw. I carry a chainsaw sharpening kit with me at all times. Learn how to sharpen your chain using a file and guide. Sharpening your chain every time you refuel is a good rule of thumb.

  • Filing Angle: Maintaining the correct filing angle is essential. Husqvarna chains typically require a 30-degree filing angle for the cutting edges and a 60-degree angle for the depth gauges (rakers). Use a file guide to ensure consistent angles.
  • Depth Gauges (Rakers): The depth gauges control how much the chain bites into the wood. If they are too high, the chain won’t cut effectively. If they are too low, the chain will grab aggressively, increasing the risk of kickback. Use a flat file and a depth gauge tool to maintain the correct height.
  • Sharpening Frequency: The frequency of sharpening depends on the type of wood you’re cutting. Softer woods like pine require less frequent sharpening than hardwoods like oak or maple. As a general rule, sharpen your chain whenever you notice it’s taking more effort to cut, producing sawdust instead of chips, or pulling to one side.

• Bar Condition: Inspect the bar for damage, wear, and burrs. A worn or damaged bar can cause the chain to derail and can reduce cutting efficiency. Use a bar dressing tool to remove burrs and square up the edges of the bar. Check the bar oiling hole to ensure it’s clear and unobstructed. I use a small piece of wire to clean it out. Also, flip the bar periodically (every few chain sharpenings) to even out wear.

• Air Filter Inspection: A clean air filter is crucial for engine performance. A dirty air filter restricts airflow, causing the engine to run lean and overheat. Remove the air filter and inspect it for dirt and debris. Clean it with compressed air or wash it with warm, soapy water. Allow it to dry completely before reinstalling. I recommend having a spare air filter on hand so you can swap it out immediately while the other one dries.

  • Filter Type: Husqvarna chainsaws typically use either foam or felt air filters. Foam filters can be washed and reused multiple times, while felt filters may need to be replaced more frequently.

Case Study: I was helping a friend clear some brush after a storm. He had a remanufactured Husqvarna 455 Rancher. He complained that it was underpowered. After inspecting it, I found the air filter completely clogged with sawdust. Cleaning the filter restored the saw’s power and efficiency. This simple check saved him a lot of frustration and potential engine damage.

Measurement: I typically use a 5/32″ file for sharpening my Husqvarna chain, but the size depends on the chain pitch. Consult your chainsaw manual for the correct file size.

2. Mastering the Art of Chain Lubrication: More Than Just Filling the Tank

Proper chain lubrication is absolutely critical for the life of your chain and bar. Insufficient lubrication causes excessive friction, leading to premature wear, overheating, and even chain breakage. I’ve seen countless chains ruined because of inadequate lubrication.

• Choosing the Right Oil: As mentioned earlier, I prefer vegetable-based bar and chain oil. It’s biodegradable, which is a plus for the environment, and it provides excellent lubrication. However, it’s important to choose an oil specifically designed for chainsaws. Regular motor oil is not suitable.
• Adjusting the Oiler: Most Husqvarna chainsaws have an adjustable oiler. This allows you to control the amount of oil being delivered to the chain. Adjust the oiler based on the type of wood you’re cutting and the ambient temperature. Hardwoods and hot weather require more oil than softwoods and cold weather. The goal is to have a thin film of oil visible on the chain at all times. I usually start with the oiler set to the maximum and then adjust it down until I see a consistent film of oil without excessive splatter.
• Checking for Proper Oiling: There’s a simple test to check if your chain is receiving adequate lubrication. Hold the running chainsaw a few inches above a light-colored surface (like a piece of cardboard) and rev the engine briefly. You should see a fine mist of oil being thrown off the chain. If you don’t see any oil, check the oiler for obstructions and make sure the oil tank is full.

• Cleaning the Oiler: The oiler can become clogged with sawdust and debris, especially if you’re cutting dirty or resinous wood. Regularly clean the oiler by removing the bar and chain and using a small brush or compressed air to clear any obstructions.

  • Oiler Location: The oiler is typically located near the base of the bar, where it connects to the chainsaw body. Consult your chainsaw manual for the exact location.

Personalized Story: I once spent an entire afternoon trying to figure out why my chainsaw was bogging down and overheating. I checked everything – fuel, air filter, spark plug – but nothing seemed to work. Finally, I realized that the oiler was completely clogged with sawdust. After cleaning it out, the saw ran like new. It was a frustrating experience, but it taught me the importance of regular oiler maintenance.

Data and Insight: A study by Oregon Tool (a leading manufacturer of chainsaw chains and bars) found that proper chain lubrication can extend the life of a chain by up to 50%. This translates to significant cost savings over time.

Tool Specification: I use a small wire brush and compressed air to clean the oiler on my Husqvarna 455 Rancher. A dental pick can also be helpful for removing stubborn debris.

3. Fuel System Finesse: Keeping the Engine Purring

The fuel system is the heart of your chainsaw. Keeping it clean and well-maintained is crucial for reliable starting and smooth operation. Problems with the fuel system are a major cause of chainsaw breakdowns.

• Using Fresh Fuel: Gasoline degrades over time, especially when mixed with oil. Stale fuel can cause starting problems, poor performance, and even engine damage. Always use fresh fuel, and discard any fuel that’s been sitting in the tank for more than a month or two. I recommend using fuel stabilizer to extend the life of your fuel, especially if you don’t use your chainsaw frequently.

  • Ethanol Content: Be mindful of the ethanol content in your gasoline. Ethanol can absorb moisture, which can lead to corrosion and other problems. I prefer using ethanol-free gasoline whenever possible. If you must use gasoline with ethanol, make sure to use a fuel stabilizer specifically designed to protect against ethanol-related issues.

• Cleaning the Fuel Filter: The fuel filter prevents dirt and debris from entering the carburetor. A clogged fuel filter can restrict fuel flow, causing the engine to run lean and stall. Regularly inspect and clean the fuel filter. To do this, remove the fuel line from the fuel tank and use a small hook or wire to pull out the filter. Clean it with carburetor cleaner or replace it if it’s heavily soiled.

• Maintaining the Carburetor: The carburetor is responsible for mixing fuel and air in the correct proportions. A dirty or improperly adjusted carburetor can cause a variety of problems, including starting difficulties, poor performance, and excessive fuel consumption. If you’re experiencing carburetor-related issues, you may need to clean or rebuild it. This is a more complex task that may require specialized tools and knowledge. If you’re not comfortable working on carburetors, it’s best to take your chainsaw to a qualified technician.

  • Carburetor Adjustment: Most Husqvarna chainsaws have adjustable carburetors with three screws: L (low speed), H (high speed), and T (idle speed). Adjusting these screws can fine-tune the engine’s performance. However, it’s important to make small adjustments and to consult your chainsaw manual for the correct settings. Over-adjusting the carburetor can damage the engine.

• Draining the Fuel Tank: If you’re storing your chainsaw for an extended period of time, it’s a good idea to drain the fuel tank. This will prevent the fuel from degrading and causing problems. To drain the fuel tank, simply remove the fuel cap and tip the chainsaw over to allow the fuel to drain out.

Original Insight: I’ve found that using a small, inline fuel filter in addition to the stock fuel filter can significantly improve fuel system cleanliness and prevent carburetor problems. This is especially helpful if you’re using fuel from a questionable source.

Example from Real Project: I was helping a neighbor cut firewood. His chainsaw, a remanufactured Husqvarna 350, kept stalling. After checking the fuel filter, I found it completely clogged with sediment. Replacing the filter solved the problem immediately.

Cost: A new fuel filter typically costs around $5-$10.

4. The Spark Plug Secret: Igniting Performance

The spark plug is responsible for igniting the fuel-air mixture in the engine. A faulty spark plug can cause starting problems, misfires, and reduced power. It’s a small component, but it plays a vital role in your chainsaw’s performance.

• Inspecting the Spark Plug: Regularly inspect the spark plug for signs of wear, fouling, or damage. Remove the spark plug and examine the electrode. It should be clean and dry, with a light tan color. If the electrode is black, oily, or covered in deposits, it’s time to clean or replace the spark plug.
• Cleaning the Spark Plug: You can clean a spark plug using a wire brush or a spark plug cleaner. Be careful not to damage the electrode. After cleaning, check the spark plug gap using a feeler gauge. The gap should be within the range specified in your chainsaw manual. Adjust the gap if necessary.

• Replacing the Spark Plug: Spark plugs are relatively inexpensive, so it’s a good idea to replace them periodically, even if they don’t appear to be damaged. I typically replace the spark plug in my chainsaw once a year, or more frequently if I’m using it heavily.

  • Spark Plug Type: Make sure to use the correct type of spark plug for your chainsaw. Using the wrong spark plug can damage the engine. Consult your chainsaw manual for the recommended spark plug type.

• Checking for Spark: If your chainsaw won’t start, one of the first things you should check is the spark. To do this, remove the spark plug and attach it to the spark plug wire. Hold the spark plug against the engine block and pull the starter cord. You should see a strong, blue spark jumping across the electrode. If you don’t see a spark, the spark plug is faulty or there’s a problem with the ignition system.

Strategic Advantage: Keeping a spare spark plug on hand can save you a lot of time and frustration in the field. I always carry a spare spark plug in my chainsaw kit.

Skill Level Required: Replacing a spark plug is a relatively simple task that can be performed by anyone with basic mechanical skills.

Timing Estimate: Replacing a spark plug typically takes less than 5 minutes.

5. Storage Savvy: Protecting Your Investment

Proper storage is essential for extending the life of your chainsaw. Neglecting to store your chainsaw properly can lead to corrosion, fuel system problems, and other issues.

• Cleaning the Chainsaw: Before storing your chainsaw, clean it thoroughly. Remove any sawdust, debris, or oil. Pay particular attention to the bar, chain, and air filter.
• Draining the Fuel Tank (or Using Fuel Stabilizer): As mentioned earlier, it’s a good idea to drain the fuel tank if you’re storing your chainsaw for an extended period of time. Alternatively, you can add fuel stabilizer to the fuel tank to prevent the fuel from degrading.
• Oiling the Chain and Bar: Apply a light coat of bar and chain oil to the chain and bar to prevent rust and corrosion.
• Storing in a Dry Place: Store your chainsaw in a dry, well-ventilated place. Avoid storing it in a damp or humid environment, as this can lead to rust and corrosion.
• Using a Chainsaw Case: A chainsaw case can protect your chainsaw from dust, dirt, and damage during storage. It also makes it easier to transport the chainsaw.

Wood Type Selection: When storing your chainsaw, avoid placing it near wood that is prone to attracting moisture, such as green wood.

Safety Considerations: Always remove the spark plug wire before storing your chainsaw to prevent accidental starting.

Debarking Logs: Before storing logs near your chainsaw, consider debarking them. Bark can harbor insects and moisture, which can damage your chainsaw.

Drying Methods: If you’re storing firewood near your chainsaw, make sure the firewood is properly dried. Green wood can release moisture that can damage your chainsaw.

Cost: A chainsaw case typically costs around $30-$50.

Additional Tips for Remanufactured Chainsaws:

• Pay extra attention to the oiling system: Remanufactured chainsaws may have slightly more wear on the oil pump, so ensure it’s functioning optimally.
• Check the bar for straightness: A bent bar can cause chain derailment and uneven wear.
• Inspect the clutch: The clutch transfers power from the engine to the chain. Ensure it’s engaging and disengaging smoothly.
• Don’t overwork it: While Husqvarna chainsaws are durable, a remanufactured model may not be able to handle the same level of abuse as a brand-new one. Be mindful of its limitations.
