Husqvarna 560 XP Chainsaw Troubleshooting: 5 Pro Fixes

The Husqvarna 560 XP is a mid-sized professional chainsaw known for its power and efficiency. It’s a popular choice for felling, limbing, and bucking. Before diving into troubleshooting, let’s define a few key terms relevant to wood processing and chainsaw operation:

• Felling: The process of cutting down a tree.
• Limbing: Removing branches from a felled tree.
• Bucking: Cutting a log into shorter, more manageable lengths.
• Green Wood: Freshly cut wood with a high moisture content. Typically, over 30% moisture.
• Seasoned Wood: Wood that has been dried, reducing its moisture content. Ideal for firewood, usually below 20% moisture.

Now, let’s get to the fixes.

1. Chainsaw Won’t Start: Fuel System Issues

One of the most common issues I encounter is a chainsaw that simply won’t start. Often, the culprit is the fuel system.

Understanding the Problem:

The fuel system delivers the necessary fuel-air mixture to the engine. Issues can range from old fuel to a clogged fuel filter.

Step-by-Step Solution:

1. Check the Fuel: This is the first and simplest step. Old fuel can become stale and lose its combustibility. I recommend using fresh fuel (less than 30 days old) mixed with the correct ratio of 2-stroke oil, as specified by Husqvarna (usually 50:1). I once had a saw that refused to start after sitting for just two weeks with fuel in it. I drained the tank, added fresh fuel, and it fired right up.
2. Inspect the Fuel Filter: Located inside the fuel tank, the fuel filter prevents debris from entering the carburetor. A clogged filter restricts fuel flow. To access the filter, use a hooked wire to pull it out through the fuel tank opening. Examine the filter for dirt and debris. If it’s clogged, replace it. Fuel filters are inexpensive and readily available. I usually replace mine every 3-6 months, depending on how frequently I use the saw.
3. Check the Fuel Lines: Inspect the fuel lines for cracks, leaks, or kinks. Cracks can allow air to enter the fuel system, disrupting the fuel-air mixture. Replace any damaged fuel lines. Over time, fuel lines can become brittle and prone to cracking, especially in colder climates.
4. Clean the Carburetor: The carburetor mixes fuel and air. A dirty or clogged carburetor can prevent the engine from starting. Carburetors are complex, and cleaning them requires some disassembly. If you’re not comfortable doing this yourself, take the saw to a qualified repair shop. However, if you’re mechanically inclined, you can try cleaning it yourself using carburetor cleaner. Disassemble the carburetor carefully, noting the position of each part. Spray all the jets and passages with carburetor cleaner, and then reassemble. Pay close attention to the idle adjustment screw and the high-speed adjustment screw settings. Typically, these are set to about 1-1/2 turns out from fully seated, but consult your owner’s manual for specific settings.
5. Check the Spark Plug: A faulty spark plug can also prevent the engine from starting. Remove the spark plug and inspect it. The electrode should be clean and dry. If it’s fouled with carbon deposits, clean it with a wire brush or replace it. Check the spark gap using a spark plug gap tool. The correct gap for the Husqvarna 560 XP is typically 0.5 mm (0.020 inches). If the spark plug is wet, it indicates that the engine is flooded. Try pulling the starter cord several times with the choke off to clear the excess fuel.

Tools Needed:

• Fuel filter removal tool (hooked wire)
• Screwdrivers
• Carburetor cleaner
• Spark plug wrench
• Spark plug gap tool

Strategic Advantage:

Maintaining a clean fuel system is crucial for the longevity and performance of your chainsaw. Regular inspection and maintenance can prevent costly repairs down the road. I always keep spare fuel filters and spark plugs on hand, so I can quickly address these issues in the field.

2. Chainsaw Runs Poorly: Carburetor Adjustment

Even if your chainsaw starts, it may run poorly due to an improperly adjusted carburetor. This can manifest as stalling, poor acceleration, or excessive smoking.

Understanding the Problem:

The carburetor controls the fuel-air mixture. Incorrect settings can lead to either a lean (too much air) or rich (too much fuel) mixture, both of which can negatively impact performance.

Step-by-Step Solution:

1. Locate the Adjustment Screws: The carburetor has three adjustment screws: the low-speed (L) screw, the high-speed (H) screw, and the idle speed (T) screw. These screws control the fuel-air mixture at different engine speeds.
2. Start with the Idle Speed (T) Screw: Adjust the idle speed screw so that the chain does not move when the engine is idling. If the chain is moving, turn the screw counterclockwise until it stops.
3. Adjust the Low-Speed (L) Screw: With the engine idling, slowly turn the low-speed screw in (clockwise) until the engine starts to stumble or stall. Then, slowly turn it out (counterclockwise) until the engine starts to run smoothly. The goal is to find the point where the engine idles smoothly and responds quickly to throttle input.
4. Adjust the High-Speed (H) Screw: This screw is more critical and requires careful adjustment. Important: Do not run the engine lean for extended periods, as this can damage the engine. With the engine running at full throttle, slowly turn the high-speed screw in until the engine starts to bog down or lose power. Then, slowly turn it out until the engine reaches its maximum RPM. The goal is to find the point where the engine runs smoothly at full throttle without bogging down or sounding strained. You can use a tachometer to measure the engine RPM. The Husqvarna 560 XP typically has a maximum RPM of around 9600-10200 RPM.
5. Fine-Tune the Adjustments: After adjusting the low-speed and high-speed screws, recheck the idle speed and make any necessary adjustments.

My Experience:

I once struggled with a chainsaw that would start fine but stall as soon as I applied throttle. After several attempts at cleaning the carburetor, I realized the issue was with the high-speed screw. It was set too lean, causing the engine to starve for fuel under load. After carefully adjusting the high-speed screw, the saw ran like a champ.

Tools Needed:

• Screwdriver
• Tachometer (optional)

Strategic Advantage:

Proper carburetor adjustment is essential for optimizing engine performance, fuel efficiency, and engine life. It also ensures that the chainsaw meets emissions standards. I recommend checking and adjusting the carburetor periodically, especially after significant changes in altitude or temperature.

3. Chainsaw Chain Problems: Dull Chain, Incorrect Tension, and Oiling Issues

A dull chain, incorrect tension, or inadequate chain lubrication can significantly impact the chainsaw’s cutting performance and safety.

Understanding the Problem:

A sharp chain is crucial for efficient cutting. A dull chain requires more force, increasing the risk of kickback. Incorrect chain tension can lead to chain derailment or damage to the bar and chain. Proper chain lubrication reduces friction and wear, extending the life of the chain and bar.

Step-by-Step Solution:

1. Sharpen the Chain: A dull chain is the most common cause of poor cutting performance. Sharpen the chain regularly using a chainsaw file or a chainsaw sharpener. I prefer using a chainsaw file, as it allows me to sharpen the chain in the field. When sharpening, maintain the correct filing angle and depth. The correct angle for the Husqvarna 560 XP chain is typically 30 degrees.
2. Check Chain Tension: The chain should be snug against the bar but still able to be pulled around by hand. To check the tension, pull the chain away from the bar at the midpoint. There should be approximately 1/8 inch (3 mm) of slack. Adjust the chain tension using the chain tensioning screw. Over-tightening the chain can damage the bar and chain, while under-tightening can cause the chain to derail.
3. Inspect the Oiling System: The oiler lubricates the chain, reducing friction and wear. Check the oil level in the oil tank regularly. Make sure the oiler is working properly by holding the chainsaw over a piece of cardboard and running the engine at idle. Oil should be spraying from the bar. If not, check the oiler outlet for clogs. You can use a small wire to clear any obstructions. Also, inspect the oil line for cracks or leaks.
4. Clean the Bar: The bar groove can become clogged with sawdust and debris, preventing proper chain lubrication. Clean the bar groove regularly using a bar groove cleaner or a flathead screwdriver.

Case Study:

I was once felling trees in a heavily wooded area with a lot of sap. The sap quickly clogged the bar groove, causing the chain to overheat and bind. I had to stop every few trees to clean the bar groove. To prevent this in the future, I started using a bar and chain oil specifically designed for use in sap-rich environments. This oil contains additives that help to prevent sap buildup.

Tools Needed:

• Chainsaw file or chainsaw sharpener
• Chain tensioning wrench
• Bar groove cleaner
• Screwdriver

Strategic Advantage:

Maintaining a sharp chain, proper chain tension, and adequate chain lubrication are essential for safe and efficient chainsaw operation. Regular maintenance can extend the life of the chain, bar, and oiler, saving you money in the long run. I always carry a chainsaw file, a chain tensioning wrench, and a bar groove cleaner in my toolkit.

4. Chainsaw Overheating: Cooling System Issues

Overheating can cause serious damage to your chainsaw engine. The cooling system is designed to prevent this, but it can sometimes fail.

Understanding the Problem:

The cooling system consists of the cylinder fins, the fan, and the air filter. These components work together to dissipate heat from the engine. A clogged air filter or debris-filled cylinder fins can restrict airflow, causing the engine to overheat.

Step-by-Step Solution:

1. Clean the Air Filter: A clogged air filter restricts airflow to the engine, causing it to run hotter. Clean the air filter regularly using compressed air or warm soapy water. Allow the filter to dry completely before reinstalling it. I clean my air filter after every use, especially when working in dusty conditions.
2. Clean the Cylinder Fins: The cylinder fins dissipate heat from the engine. Over time, they can become clogged with sawdust and debris. Clean the cylinder fins regularly using a brush or compressed air. Be careful not to damage the fins.
3. Check the Fan: The fan circulates air around the engine, helping to cool it. Make sure the fan is not damaged or obstructed. If the fan is damaged, replace it.

My Experience:

I once had a chainsaw that kept overheating, even after cleaning the air filter. After inspecting the cylinder fins, I discovered they were packed with sawdust. I carefully cleaned the fins with a brush and compressed air, and the overheating problem disappeared.

Tools Needed:

• Compressed air
• Brush

Strategic Advantage:

Maintaining a clean cooling system is essential for preventing engine damage and extending the life of your chainsaw. Regular cleaning can prevent overheating and ensure optimal performance. I always keep a can of compressed air in my toolkit for cleaning the air filter and cylinder fins.

5. Chainsaw Chain Brake Issues: Malfunctioning Brake

The chain brake is a critical safety feature that stops the chain immediately in the event of kickback. A malfunctioning chain brake can significantly increase the risk of injury.

Understanding the Problem:

The chain brake is activated by the front hand guard. When the hand guard is pushed forward, it engages the brake band, stopping the chain. The brake band can become worn or damaged, preventing it from effectively stopping the chain.

Step-by-Step Solution:

1. Test the Chain Brake: To test the chain brake, start the engine and engage the chain brake by pushing the front hand guard forward. The chain should stop immediately. If the chain continues to move, the chain brake is not functioning properly.
2. Inspect the Brake Band: Remove the side cover and inspect the brake band. The brake band should be clean and free of oil or grease. If the brake band is worn or damaged, replace it.
3. Adjust the Brake Band: Some chain brakes have an adjustment screw that can be used to tighten the brake band. Consult your owner’s manual for instructions on how to adjust the brake band.
4. Clean the Brake Mechanism: The brake mechanism can become clogged with sawdust and debris, preventing it from functioning properly. Clean the brake mechanism regularly using compressed air or a brush.

Safety First:

If the chain brake is not functioning properly, do not use the chainsaw until it has been repaired. A malfunctioning chain brake is a serious safety hazard.

Tools Needed:

• Screwdriver
• Compressed air
• Brush

Strategic Advantage:

A properly functioning chain brake is essential for safe chainsaw operation. Regular inspection and maintenance can ensure that the chain brake is always ready to protect you in the event of kickback. I always test the chain brake before each use.
