Because it’s reliable, powerful for its size, and, importantly, holds its value incredibly well. In fact, a well-maintained Husqvarna 346 can command a surprisingly good price on the used market.

Think about it: a quality chainsaw is an investment. Unlike some tools that depreciate rapidly, a Husqvarna 346, if treated right, will retain a significant portion of its original worth. This isn’t just about the money; it’s about having a tool you can depend on, year after year, and knowing that if you ever need to part with it, you’ll get a fair return. That’s why I am writing this, to share my experience on how to keep your Husqvarna 346 in top-notch condition and get the most out of it. I’ll share five pro tips that I’ve gathered over years of using and maintaining this iconic chainsaw. These aren’t just generic tips; they’re specific to the 346 and designed to help you achieve ultimate woodcutting performance.

Tip #1: Mastering the Art of Chain Sharpening

Why Sharpening Matters

A sharp chain is the single most important factor in efficient and safe woodcutting. Period. I’ve seen experienced loggers struggle with dull chains, wasting time and energy, and even creating dangerous situations. A dull chain doesn’t cut; it grinds, leading to increased wear on the saw, more fuel consumption, and a higher risk of kickback.

The Right Tools for the Job

There are several ways to sharpen a chainsaw chain, but I prefer using a file and guide. It gives me more control and allows me to maintain the correct angles. Here’s what you’ll need:

• Round file: The correct size for your chain (typically 5/32″ or 4.0mm for most 346 chains).
• File guide: A guide specifically designed for chainsaw chains. This ensures consistent angles and depth.
• Flat file: For lowering the depth gauges (rakers).
• Depth gauge tool: A specialized tool for checking and adjusting the height of the depth gauges.
• Vise: To securely hold the chainsaw bar while sharpening.

The Sharpening Process

1. Secure the saw: Clamp the chainsaw bar securely in a vise.
2. Identify the cutters: Determine the direction of the cutters and start with the shortest one as a reference.
3. File at the correct angle: Place the file guide on the chain and file each cutter at the manufacturer’s recommended angle (usually around 30 degrees for the top plate and 85 degrees for the side plate). Maintain consistent pressure and stroke direction.
4. File each cutter evenly: File each cutter to the same length, using the shortest cutter as a guide.
5. Lower the depth gauges: Use the depth gauge tool to check the height of the depth gauges (rakers). If they are too high, use the flat file to lower them. The depth gauge setting depends on the type of wood you’re cutting (softer wood requires lower depth gauges). For most general-purpose cutting, I recommend setting the depth gauges to 0.025″ (0.635mm).
6. Deburr: Use the flat file to remove any burrs from the cutters.

Data and Insights

• Filing Angle: Maintaining the correct filing angle is crucial for optimal cutting performance. Incorrect angles can lead to aggressive cutting (increased kickback risk) or poor cutting performance (increased friction and wear).
• Depth Gauge Setting: The depth gauge setting directly affects the amount of wood each cutter takes. A lower depth gauge setting allows the cutter to take a larger bite, which is ideal for softer woods. However, too low of a setting can increase the risk of kickback.
• Sharpening Frequency: The frequency of sharpening depends on the type of wood you’re cutting and the amount of use. As a general rule, I sharpen my chain after every tank of fuel or when I notice a decrease in cutting performance.

My Personal Experience

I once worked on a project clearing a large area of overgrown brush. The chain on my 346 was getting dull quickly due to the dirt and debris. Instead of struggling with a dull chain, I made it a habit to sharpen it every other tank of fuel. This not only made the job easier but also significantly reduced the wear and tear on my saw. I even created a small sharpening station in my truck so I could sharpen the chain on the go.

Tip #2: Fuel and Oil – The Lifeblood of Your 346

The Importance of Quality Fuels and Oils

The Husqvarna 346 is a high-performance machine, and it requires high-quality fuel and oil to run efficiently and reliably. Skimping on fuel or oil can lead to serious engine damage and shorten the lifespan of your saw. I’ve seen firsthand the consequences of using cheap or incorrect fuels and oils, from piston scoring to complete engine failure.

Fuel Recommendations

• Octane Rating: Use gasoline with a minimum octane rating of 89 (AKI) or 95 (RON). Higher octane fuels are preferable, especially in hot weather or at high altitudes.
• Ethanol Content: Limit the ethanol content to 10% (E10) or less. Ethanol can damage fuel lines and other engine components. If possible, use ethanol-free gasoline.
• Fuel Stabilizer: Add a fuel stabilizer to the gasoline, especially if you’re not going to use the saw for an extended period. Fuel stabilizers prevent the gasoline from degrading and forming deposits in the fuel system.

Oil Recommendations

• Two-Stroke Oil: Use a high-quality two-stroke oil specifically designed for air-cooled engines. I recommend using Husqvarna’s own two-stroke oil or a similar synthetic blend.
• Mixing Ratio: Mix the two-stroke oil with gasoline at the manufacturer’s recommended ratio (typically 50:1). Always follow the instructions on the oil container.
• Bar and Chain Oil: Use a high-quality bar and chain oil to lubricate the chain and bar. This reduces friction and wear and helps to prevent the chain from overheating.

Data and Insights

• Fuel Octane: Using a fuel with a lower octane rating than recommended can lead to engine knocking and reduced performance. In severe cases, it can damage the engine.
• Ethanol Content: Ethanol can absorb water from the air, which can lead to corrosion and fuel system problems. It can also degrade rubber and plastic components.
• Oil Mixing Ratio: Using too much oil can lead to excessive smoke and carbon buildup. Using too little oil can lead to insufficient lubrication and engine damage.
• Bar and Chain Oil Viscosity: The viscosity of the bar and chain oil is important for proper lubrication. In colder weather, use a lower viscosity oil to ensure adequate flow. In warmer weather, use a higher viscosity oil to prevent it from thinning out too much.

My Personal Experience

I once had a friend who insisted on using the cheapest gasoline he could find in his chainsaw. He didn’t bother to add a fuel stabilizer, and he mixed his two-stroke oil at a ratio of 100:1 (thinking he was saving money). Needless to say, his chainsaw didn’t last very long. The engine seized up after only a few months of use. This experience taught me the importance of using high-quality fuels and oils and following the manufacturer’s recommendations.

Tip #3: Carburetor Adjustment – Fine-Tuning for Peak Performance

Understanding the Carburetor

The carburetor is responsible for mixing air and fuel in the correct proportions to create a combustible mixture. A properly adjusted carburetor ensures that the engine runs smoothly, efficiently, and with optimal power. I’ve seen many 346 owners struggle with carburetor issues, leading to poor performance and even engine damage.

Carburetor Adjustment Screws

The Husqvarna 346 carburetor typically has three adjustment screws:

• L (Low-speed): Adjusts the fuel mixture at idle and low speeds.
• H (High-speed): Adjusts the fuel mixture at high speeds.
• T (Idle speed): Adjusts the engine idle speed.

Adjustment Procedure

1. Warm up the engine: Start the engine and let it warm up for a few minutes.
2. Adjust the idle speed: Turn the “T” screw until the engine idles smoothly without stalling. The recommended idle speed is around 2700-3300 RPM.
3. Adjust the low-speed mixture: Turn the “L” screw until the engine accelerates smoothly from idle to full throttle. If the engine hesitates or stumbles, turn the “L” screw slightly richer (counter-clockwise). If the engine bogs down or smokes excessively, turn the “L” screw slightly leaner (clockwise).
4. Adjust the high-speed mixture: This is the most critical adjustment. Run the engine at full throttle and turn the “H” screw until the engine runs smoothly and with optimal power. If the engine sounds strained or “four-strokes” (a characteristic “burbling” sound), turn the “H” screw slightly richer (counter-clockwise). If the engine runs smoothly but lacks power, turn the “H” screw slightly leaner (clockwise). Important: It’s better to err on the side of being slightly rich than too lean, as a lean mixture can cause engine damage.
5. Fine-tune: After making the initial adjustments, run the saw under load (cutting wood) and fine-tune the carburetor as needed.

Data and Insights

• Air/Fuel Ratio: The ideal air/fuel ratio for a two-stroke engine is around 14.7:1 (stoichiometric). However, for optimal performance and engine longevity, it’s often necessary to run slightly richer than stoichiometric, especially at high speeds.
• RPM Measurement: Using a tachometer to measure the engine RPM is highly recommended for accurate carburetor adjustment.
• Altitude Adjustment: The air density decreases with altitude, which means the carburetor needs to be adjusted leaner at higher altitudes. As a general rule, you may need to lean out the carburetor slightly for every 1000 feet (300 meters) of altitude increase.

My Personal Experience

I once had a 346 that was running poorly. It was hard to start, and it lacked power. After checking the fuel and spark plug, I realized that the carburetor was out of adjustment. I carefully followed the adjustment procedure and was able to get the saw running like new again. This experience taught me the importance of understanding the carburetor and how to adjust it properly. I now carry a small screwdriver and tachometer with me whenever I’m working with my chainsaw, just in case I need to make adjustments on the fly.

Tip #4: Regular Maintenance – Preventing Problems Before They Start

The Importance of Preventative Maintenance

Regular maintenance is essential for keeping your Husqvarna 346 running smoothly and reliably. By performing routine maintenance tasks, you can prevent small problems from turning into major repairs and extend the lifespan of your saw.

• Fuel System Maintenance: Inspect the fuel lines and fuel tank for any signs of leaks or damage. Replace the fuel filter regularly to prevent debris from entering the carburetor.

Data and Insights

• Air Filter Restriction: A restricted air filter can reduce engine power by as much as 20%.
• Spark Plug Gap: The correct spark plug gap is crucial for proper ignition. The recommended spark plug gap for the Husqvarna 346 is typically 0.020″ (0.5mm).
• Bar Wear: A worn bar can cause the chain to derail and increase the risk of kickback.
• Cooling System Efficiency: A dirty cooling system can cause the engine to overheat and lead to premature wear or failure.

My Personal Experience

I once neglected to clean the air filter on my 346 for an extended period. The engine started running poorly, and I noticed a significant decrease in power. After cleaning the air filter, the engine ran like new again. This experience taught me the importance of regular maintenance and how even a simple task like cleaning the air filter can have a big impact on performance.
