Stihl 660 CC Chainsaw Tips (5 Pro Methods for Steep Terrain)

Alright, let’s dive into the world of the Stihl 660 CC chainsaw and how to tame the beast on steep terrain. But first, let’s talk about the elephant in the room – noise.

Taming the Roar: Noise Reduction and the Stihl 660

Before we even think about tackling those slopes with the legendary Stihl 660, let’s address noise reduction. The 660 is a powerhouse, but that power comes with a roar. Hearing protection is non-negotiable. I’m talking beyond those flimsy foam earplugs. Invest in professional-grade earmuffs with a Noise Reduction Rating (NRR) of at least 25dB. Trust me, your ears will thank you later. Look for models with gel earcups for added comfort during long days in the woods. Some even come with built-in Bluetooth, so you can listen to podcasts while you work (just be sure you can still hear your surroundings!).

Beyond personal protection, consider the impact on your neighbors, especially if you’re working near residential areas. Check local ordinances regarding noise levels and operating hours for power equipment. Strategic planning can minimize noise pollution. For example, felling trees earlier in the day when ambient noise levels are higher can help mask the sound of the chainsaw. Using natural barriers like hills or dense vegetation can also help attenuate the noise.

Now, let’s get to the heart of the matter: using the Stihl 660 on steep terrain.

Stihl 660 CC Chainsaw Tips: 5 Pro Methods for Steep Terrain

The Stihl 660. It’s a chainsaw that commands respect. It’s a workhorse, a beast, and in the right hands, a tool that can fell massive trees and process timber with incredible efficiency. But put it on a steep slope, and the game changes. The challenges multiply – gravity becomes your enemy, footing is precarious, and safety becomes paramount.

The global wood processing and logging industry is a significant economic driver. According to recent reports, the global logging market size was valued at $800 billion in 2023, and is projected to reach $1.1 trillion by 2030, growing at a CAGR of 4.5% from 2024 to 2030. This growth underscores the importance of efficient and safe logging practices, especially in challenging terrains.

Over the years, I’ve learned a thing or two about wrestling with this powerful saw on inclines that would make a mountain goat think twice. I’ve seen firsthand the consequences of complacency and the rewards of meticulous planning. I’ve even had a few close calls that served as harsh but valuable lessons.

Here are five pro methods I’ve honed over years of experience to help you safely and effectively use the Stihl 660 on steep terrain:

1. Master the Stance: Footing and Body Positioning

This is the cornerstone of safe chainsaw operation, especially on slopes. Forget everything else if you don’t get this right.

Why it matters: A stable stance provides a solid base of support, preventing slips and falls. It also allows you to control the chainsaw effectively, reducing the risk of kickback and other hazards.

How to do it:

1. Assess the slope: Before you even start the saw, take a good look at the terrain. Identify any obstacles, loose rocks, or slippery patches.
2. Choose your footing: Find a solid, level spot to stand. If necessary, use your boots to create a small platform. Clear away any debris that could cause you to lose your footing.
3. Stagger your stance: Place one foot slightly ahead of the other, with your weight evenly distributed. This will give you a wider base of support and improve your balance.
4. Bend your knees: Keep your knees slightly bent to lower your center of gravity and improve your stability.
5. Maintain a wide grip: Hold the chainsaw firmly with both hands, keeping your elbows slightly bent. This will give you maximum control over the saw.
6. Body Position Relative to the Cut: Always position yourself uphill of the cut. This way, if the tree or log starts to move, it will move away from you, not towards you. Never stand directly downhill from a cut. This is a recipe for disaster.
7. Think like a dancer: Constantly adjust your footing as you work, shifting your weight and repositioning your feet to maintain a stable stance.

Pro Tip: Invest in a good pair of logging boots with aggressive tread. These boots will provide excellent traction on uneven terrain and help prevent slips and falls. I personally swear by my Whites boots; they’re expensive, but worth every penny for the ankle support and grip they provide.

Data Point: Studies have shown that slips, trips, and falls are a leading cause of injuries in the logging industry, accounting for over 20% of all accidents. Mastering your stance can significantly reduce your risk of injury.

2. Leverage and Fulcrums: Minimize Physical Exertion

The Stihl 660 is a heavy saw. Add the weight of gravity pulling you downhill, and you’ve got a recipe for exhaustion and potential injury.

Why it matters: Using leverage and fulcrums reduces the amount of physical force required to operate the chainsaw, conserving energy and minimizing strain on your body.

How to do it:

1. Utilize natural fulcrums: Look for rocks, logs, or stumps that can be used as fulcrums to support the weight of the chainsaw.
2. Employ wedges: Use wedges to prevent the saw from binding and to help direct the fall of the tree or log.
3. Leverage your body weight: Instead of relying solely on your arm strength, use your body weight to help guide the saw. Lean into the cut, using your legs and core muscles to generate power.
4. Use a Peavey or Cant Hook: These tools are invaluable for rolling logs and positioning them for cutting. They reduce the need for heavy lifting and minimize the risk of back injuries.
5. Take frequent breaks: Don’t try to power through. Stop every 15-20 minutes to rest, rehydrate, and stretch your muscles. Fatigue is a major contributor to accidents.

Pro Tip: When bucking logs on a slope, use a log jack to lift the log off the ground. This will make it easier to cut and prevent the saw from pinching. I’ve used a simple, homemade log jack constructed from a sturdy branch and a metal hinge. It’s not pretty, but it gets the job done.

Real-World Example: I once saw a logger try to buck a large log on a steep slope without using a log jack. The saw pinched, the log rolled unexpectedly, and he nearly lost his footing. It was a close call that could have been avoided with a simple tool.

3. Precision Felling: Directional Control on Slopes

Felling trees on steep terrain requires careful planning and execution. You can’t just point and shoot.

Why it matters: Controlling the direction of the fall is crucial for safety and efficiency. A misdirected tree can damage property, injure workers, or create a dangerous situation.

How to do it:

1. Assess the lean: Determine the natural lean of the tree. This will be a major factor in determining the direction of the fall.
2. Consider the wind: Wind can significantly affect the direction of the fall. Pay close attention to the wind direction and adjust your felling plan accordingly.
3. Plan your escape route: Before you start cutting, identify a clear escape route that is free of obstacles. Make sure you know where you’re going to run if the tree starts to fall unexpectedly.
4. Use a bore cut: A bore cut is a technique that involves plunging the saw into the tree and cutting out a section of wood to create a hinge. This hinge will help control the direction of the fall.
5. Drive wedges: After making the bore cut, drive wedges into the back cut to help lift the tree and direct its fall.
6. Communicate: If you’re working with a team, communicate clearly and frequently. Let everyone know your felling plan and escape route.

Pro Tip: On steep slopes, it’s often best to fell trees uphill. This will prevent the tree from sliding downhill and potentially causing damage or injury. However, this requires careful planning and execution, as the tree will have a tendency to roll back towards you.

Case Study: A logging company in Oregon was tasked with felling trees on a steep, heavily forested slope. By using precision felling techniques, including bore cuts and wedges, they were able to safely and efficiently fell the trees without any accidents or damage to property. They also minimized soil erosion by carefully controlling the direction of the fall.

4. Chain Maintenance: Keeping Your 660 Sharp and Safe

A dull chain is a dangerous chain. Period.

Why it matters: A sharp chain cuts more efficiently, reduces the risk of kickback, and minimizes strain on the chainsaw.

How to do it:

1. Sharpen regularly: Sharpen your chain every time you refuel the saw. This will ensure that the chain is always sharp and ready to cut.
2. Use a file guide: A file guide will help you maintain the correct filing angle and depth, ensuring that the chain is properly sharpened.
3. Check the depth gauges: The depth gauges control the amount of wood that the chain can cut. If the depth gauges are too high, the chain will not cut effectively. If they are too low, the chain will be too aggressive and prone to kickback.
4. Clean the chain: Keep the chain clean and free of debris. Dirt and grime can dull the chain and reduce its cutting efficiency.
5. Inspect the chain: Regularly inspect the chain for damage, such as cracks or broken teeth. Replace the chain if it is damaged.

Pro Tip: Invest in a good quality chainsaw sharpener. A bench grinder with a chain sharpening attachment will make it much easier to sharpen your chains quickly and accurately. I use a Oregon 511AX bench grinder, and it’s been a game-changer for maintaining my chains.

Data Point: Studies have shown that a sharp chainsaw chain can reduce the risk of kickback by up to 50%.

5. The Buddy System: Never Work Alone

This is non-negotiable, especially on steep terrain.

Why it matters: Working with a partner provides an extra set of eyes and ears, allowing you to identify potential hazards and respond quickly to emergencies.

How to do it:

1. Choose a reliable partner: Select someone who is experienced in chainsaw operation and familiar with the terrain.
2. Communicate clearly: Establish clear communication protocols before you start working. Use hand signals or radios to communicate effectively, especially in noisy environments.
3. Stay within sight and earshot: Keep your partner within sight and earshot at all times. This will allow you to provide assistance if needed.
4. Have a plan for emergencies: Develop a plan for dealing with emergencies, such as injuries or equipment failures. Make sure you have a first-aid kit and a way to call for help.
5. Share the workload: Divide the tasks evenly between partners to prevent fatigue.

Pro Tip: Before you start working, conduct a thorough risk assessment with your partner. Identify potential hazards and develop strategies for mitigating those risks.

Personal Story: I once had a close call while felling a tree on a steep slope. The tree started to fall unexpectedly, and I lost my footing. Luckily, my partner was there to warn me and help me regain my balance. Without his quick thinking and assistance, I could have been seriously injured.

Beyond the Basics: Advanced Techniques and Considerations

Now that we’ve covered the fundamentals, let’s delve into some advanced techniques and considerations for using the Stihl 660 on steep terrain.

Wood Species and Firewood Quality

Not all wood is created equal. The species of wood you’re processing will significantly impact its quality as firewood.

• Hardwoods vs. Softwoods: Hardwoods like oak, maple, and ash are denser and contain more energy per unit volume than softwoods like pine, fir, and spruce. Hardwoods burn longer and produce more heat.
• Resin Content: Softwoods tend to have a higher resin content, which can cause them to burn quickly and produce more smoke and creosote buildup in chimneys.
• Seasoning Time: Hardwoods require a longer seasoning time than softwoods. Oak, for example, can take up to two years to season properly, while pine may be ready in as little as six months.

Data Point: Oak firewood has an average BTU (British Thermal Unit) rating of 27.7 million per cord, while pine firewood has an average BTU rating of 15.8 million per cord. This means that oak firewood produces significantly more heat than pine firewood.

Green Wood vs. Seasoned Wood

Understanding the difference between green wood and seasoned wood is crucial for producing high-quality firewood.

• Green Wood: Green wood is freshly cut wood that has a high moisture content. It is difficult to burn, produces a lot of smoke, and has a low heat output.
• Seasoned Wood: Seasoned wood is wood that has been dried to a moisture content of 20% or less. It burns easily, produces less smoke, and has a high heat output.

How to Season Wood:

1. Split the wood: Splitting the wood increases the surface area, allowing it to dry more quickly.
2. Stack the wood: Stack the wood in a single row, with the bark side up. This will help to shed water and prevent rot.
3. Elevate the wood: Elevate the wood off the ground using pallets or skids. This will improve air circulation and prevent moisture from wicking up into the wood.
4. Cover the wood: Cover the top of the woodpile with a tarp or roof to protect it from rain and snow.
5. Allow ample time: Allow the wood to season for at least six months, and preferably a year or more.

Original Research: I conducted a small-scale experiment to compare the drying rates of different wood species. I split and stacked oak, maple, and pine firewood in the same location and measured their moisture content over a period of one year. The results showed that oak took the longest to dry, followed by maple, and then pine. This confirmed the conventional wisdom that hardwoods require a longer seasoning time than softwoods.

Costs and Budgeting

Wood processing and firewood preparation can be expensive. Here are some cost considerations:

• Chainsaw: The Stihl 660 is a premium chainsaw that can cost upwards of $1,500.
• Safety Gear: Safety gear, such as a helmet, earmuffs, eye protection, and chaps, can cost several hundred dollars.
• Tools: Tools, such as a splitting maul, wedges, and a log jack, can cost several hundred dollars.
• Fuel and Oil: Fuel and oil can be a significant expense, especially if you are processing a large amount of wood.
• Maintenance: Chainsaw maintenance, such as sharpening and repairs, can cost several hundred dollars per year.

Budgeting Tips:

• Buy used equipment: Consider buying used equipment to save money.
• Maintain your equipment: Regular maintenance will extend the life of your equipment and prevent costly repairs.
• Shop around for fuel and oil: Prices for fuel and oil can vary significantly.
• Process your own wood: Processing your own wood can save you money compared to buying firewood.
