Pro Tip #1: Mastering Chain Selection and Sharpening

The chain is the heart of any chainsaw, and selecting the right chain for the job is crucial for optimal performance. Similarly, a dull chain not only slows down your work but also increases the risk of kickback and other accidents.

Chain Types and Applications

Full-Chisel Chains: These chains have square-cornered cutters that slice through wood quickly and efficiently. They are ideal for felling and bucking clean, softwood logs. However, they are more prone to damage from dirt and debris.
Semi-Chisel Chains: These chains have rounded cutters that are more forgiving when cutting dirty or frozen wood. They are a good all-around choice for general woodcutting tasks.
Low-Profile Chains: These chains have a smaller cutter profile and are designed to reduce kickback. They are often used on smaller chainsaws and are a good choice for beginners.
Ripping Chains: These chains are specifically designed for cutting wood parallel to the grain, such as when milling lumber. They have a unique cutter geometry that produces smooth, accurate cuts.

I typically use a full-chisel chain for felling and bucking clean logs because it offers the fastest cutting speed. However, when working in areas with a lot of dirt or debris, I switch to a semi-chisel chain to prolong the chain’s life.

Chain Sharpening Techniques

Sharpening your chain regularly is essential for maintaining optimal performance and safety. A sharp chain will cut faster, reduce strain on the saw’s engine, and decrease the risk of kickback.

Filing: Filing is the most common method of sharpening chainsaw chains. It involves using a round file and a file guide to sharpen each cutter to the correct angle and depth. I recommend using a file guide to ensure consistent sharpening and prevent damage to the cutters.
- File Size: Use the correct file size for your chain pitch. A 3/8″ chain typically requires a 5/32″ file.
- Filing Angle: Maintain the correct filing angle as specified by the chain manufacturer. This is typically around 30 degrees.
- Depth Gauge: Check and adjust the depth gauges (rakers) after sharpening. The depth gauges control the amount of wood each cutter takes. If they are too high, the chain will not cut effectively. If they are too low, the chain will grab and increase the risk of kickback.
Electric Sharpeners: Electric sharpeners can quickly and accurately sharpen chainsaw chains. However, they can also be aggressive and remove too much material if not used carefully. I recommend using an electric sharpener only if you have experience and know how to adjust the settings properly.
Grinding: Grinding is a more aggressive method of sharpening chainsaw chains that uses a grinding wheel to remove material. It is typically used to repair damaged chains or to reshape cutters. I recommend leaving grinding to professionals, as it is easy to damage the chain if not done correctly.

I sharpen my chains after every few tanks of fuel, or more often if I notice the chain is cutting slowly or unevenly. I prefer to use a file and file guide because it gives me more control over the sharpening process.

Takeaway: Selecting the right chain for the job and keeping it properly sharpened are crucial for maximizing the performance and safety of your Husqvarna 592 XP. Experiment with different chain types to find what works best for your specific needs and conditions. Invest in a good quality file and file guide, and practice your sharpening technique until you can consistently produce sharp, even cutters.

Pro Tip #2: Optimizing Bar and Chain Oiling

Proper lubrication is essential for extending the life of your bar and chain and ensuring smooth, efficient cutting. Insufficient lubrication can lead to premature wear, overheating, and even catastrophic failure of the bar and chain.

Understanding Bar and Chain Oil

Bar and chain oil is specially formulated to lubricate the bar and chain of a chainsaw. It is typically a high-viscosity oil that clings to the metal surfaces and prevents friction.

Viscosity: The viscosity of the oil is important because it determines how well the oil will stick to the bar and chain. A higher viscosity oil will provide better lubrication, especially in hot weather or when cutting hardwoods.
Tackifiers: Many bar and chain oils contain tackifiers, which are additives that help the oil cling to the metal surfaces. This is especially important for high-speed chainsaws like the 592 XP.
Biodegradable Oils: Biodegradable bar and chain oils are available and are a good choice for environmentally conscious users. However, they may not provide the same level of lubrication as traditional oils.

I always use a high-quality bar and chain oil that is specifically designed for chainsaws. I prefer oils with tackifiers because they provide better lubrication and reduce wear. I also consider using biodegradable oils when working in environmentally sensitive areas.

Adjusting the Oil Pump

The Husqvarna 592 XP has an adjustable oil pump that allows you to control the amount of oil delivered to the bar and chain. Adjusting the oil pump is crucial for ensuring adequate lubrication without wasting oil.

Too Little Oil: If the oil pump is set too low, the bar and chain will not be adequately lubricated, leading to premature wear and overheating. Signs of insufficient lubrication include smoke coming from the bar and chain, a blue discoloration of the bar, and a tight or binding chain.
Too Much Oil: If the oil pump is set too high, you will waste oil and create a mess. Signs of excessive lubrication include oil dripping from the bar when the saw is idle and oil splattering excessively when cutting.

I adjust the oil pump so that the bar and chain are adequately lubricated without excessive oil consumption. I typically start with the oil pump set to the middle setting and then adjust it as needed based on the cutting conditions.

Checking for Proper Oiling

Regularly checking for proper oiling is essential for preventing damage to the bar and chain.

Oil Output Test: To check the oil output, start the saw and hold it over a piece of cardboard or clean wood. You should see a steady stream of oil coming from the bar. If the oil stream is weak or intermittent, check the oil level, oil filter, and oil pump.
Bar Groove Cleaning: Regularly clean the bar groove to ensure proper oil flow. The bar groove can become clogged with sawdust and debris, which can restrict oil flow. I use a bar groove cleaner or a small screwdriver to clean the groove.
Bar Rail Maintenance: Keep the bar rails clean and square. The bar rails are the edges of the bar that the chain rides on. If the rails are damaged or worn, the chain will not run smoothly, and the bar will wear prematurely. I use a bar rail dressing tool to keep the rails clean and square.

Takeaway: Proper bar and chain oiling is crucial for extending the life of your bar and chain and ensuring smooth, efficient cutting. Use a high-quality bar and chain oil, adjust the oil pump to the appropriate setting, and regularly check for proper oiling. By following these tips, you can prevent premature wear and keep your Husqvarna 592 XP running smoothly for years to come.

Wind: Pay attention to the wind direction and speed. Strong winds can make felling unpredictable and dangerous.
Obstacles: Identify any obstacles that could interfere with the tree’s fall, such as other trees, power lines, or buildings.
Escape Routes: Plan two escape routes that are at a 45-degree angle away from the intended felling direction. Clear these routes of any obstacles.

I always take my time to thoroughly assess the tree and its surroundings before felling. I use a plumb bob to determine the tree’s lean and a clinometer to measure the slope of the ground. I also check for any signs of decay or disease in the tree.

Making the Notch

The notch, or face cut, is a critical step in felling a tree. It determines the direction the tree will fall and helps to control the fall.

Notch Angle: The notch angle should be approximately 70-90 degrees.
Notch Depth: The notch depth should be about one-fifth to one-third of the tree’s diameter.
Notch Alignment: The notch should be aligned with the intended felling direction.

I use a combination of the open face notch and the conventional notch, depending on the size and lean of the tree. The open face notch allows for a wider range of felling directions, while the conventional notch provides more control.

Making the Back Cut

The back cut is the final cut that severs the tree from its stump. It should be made slightly above the notch and should leave a hinge of wood to control the fall.

Hinge Width: The hinge width should be about one-tenth of the tree’s diameter.
Hinge Thickness: The hinge thickness should be about one inch.
Back Cut Alignment: The back cut should be aligned with the notch.

I use a felling lever or wedges to help guide the tree’s fall and prevent it from pinching the saw. I also use a spotter to watch the tree’s movement and warn me of any potential hazards.

Felling Large Trees Safely

Felling large trees can be dangerous, but by following these safety precautions, you can minimize the risk of accidents.

Wear Appropriate Safety Gear: Always wear a helmet, eye protection, hearing protection, gloves, and chainsaw chaps.
Maintain a Safe Distance: Keep a safe distance from the tree while it is falling. The distance should be at least twice the tree’s height.
Be Aware of Your Surroundings: Pay attention to your surroundings and be aware of any potential hazards.
Don’t Work Alone: Always work with a partner who can assist you in case of an emergency.

Takeaway: Felling large trees safely and efficiently requires careful planning, precise cutting techniques, and a thorough understanding of safety procedures. The Husqvarna 592 XP is a powerful tool for felling large trees, but it’s essential to use it responsibly and with respect for the potential hazards involved.
