MS 661 Magnum Chainsaw: 5 Pro Tips for Ultimate Wood Cutting
The Stihl MS 661 Magnum. Just the name evokes images of power and performance. It’s a chainsaw that’s earned its reputation as a go-to for professionals tackling the toughest jobs. But owning a high-performance saw is only half the battle. To truly unlock its potential and achieve ultimate wood cutting, you need to combine that power with knowledge and skill. These aren’t just tips; they’re hard-earned lessons from the field.
1. Mastering the Art of Chain Selection and Sharpening
It sounds basic, but it’s the foundation of everything. You can have the most powerful chainsaw in the world, but if your chain is dull or the wrong type, you’re fighting a losing battle.
Chain Selection: Matching the Chain to the Task
There’s no one-size-fits-all chain. Different chains are designed for different purposes. For example:
- Full Chisel Chains: These are aggressive cutters, ideal for clean wood and felling trees. They offer the fastest cutting speed, but they dull more quickly and are more susceptible to damage from dirt or debris.
- Semi-Chisel Chains: A good all-around choice, semi-chisel chains offer a balance of cutting speed and durability. They’re more forgiving in dirty conditions than full chisel chains.
- Low-Kickback Chains: Designed with safety in mind, these chains have features that reduce the risk of kickback. They’re a good choice for less experienced users or when working in awkward positions.
- Ripping Chains: These chains are specifically designed for milling lumber, cutting along the grain of the wood. They have a different cutter geometry that produces a smoother cut.
My Experience: I once tried to fell a large oak with a ripping chain. The experience was… less than ideal. The saw bogged down constantly, and the cut was slow and rough. It was a painful reminder that using the right tool for the job is crucial.
Data Point: According to a study by Oregon Products, using the correct chain type for a specific task can improve cutting efficiency by up to 30%.
The Importance of Sharpness
A sharp chain is not just about cutting faster; it’s about safety. A dull chain requires more force to cut, increasing the risk of kickback and operator fatigue.
Sharpening Techniques:
- Hand Sharpening: This is the most common method, using a file and guide to sharpen each cutter individually. It requires practice and patience to master, but it allows you to maintain a consistent angle and depth.
- Electric Sharpeners: These sharpeners offer a faster and more consistent sharpening experience. However, they can be more aggressive and remove more material from the chain.
- Grinding Wheels: Used for heavy sharpening or repairing damaged chains, grinding wheels require a steady hand and a good understanding of chain geometry.
My Experience: I remember one particularly grueling firewood season where I neglected my chain sharpening. The result? Exhaustion, frustration, and a lot of wasted time. I learned my lesson the hard way: a few minutes spent sharpening the chain can save hours of back-breaking work.
Data Point: A sharp chain can reduce cutting time by up to 50% compared to a dull chain, according to a study by Stihl.
Unique Insight: Don’t just sharpen when the chain feels dull. Develop a sharpening schedule based on the type of wood you’re cutting and the amount of use. For example, if you’re cutting hardwood, you may need to sharpen the chain after every tank of gas.
Actionable Takeaway: Invest in a quality chain sharpening kit and learn how to use it properly. There are plenty of online resources and videos that can guide you. Practice makes perfect!
Example: Let’s say you’re preparing firewood using a MS 661 Magnum.
- Equipment Used: MS 661 Magnum, semi-chisel chain, chain sharpening kit (file, guide, depth gauge).
- Wood Type: Mixed hardwood (oak, maple, ash).
- Safety Considerations: Wear appropriate PPE (Personal Protective Equipment), including safety glasses, hearing protection, gloves, and chaps.
- Process: After every two tanks of gas, inspect the chain for sharpness. If the chain is pulling to one side, creating fine sawdust instead of chips, or requiring excessive force to cut, it’s time to sharpen. Use the file and guide to sharpen each cutter, maintaining the correct angle and depth.
2. Mastering the Felling Cut: Precision and Safety First
Felling a tree is one of the most dangerous tasks you can undertake with a chainsaw. It requires careful planning, precise cutting, and a healthy dose of respect for the power of nature.
Planning the Felling Cut:
Assessing the Tree: Before you even start the saw, take the time to assess the tree and its surroundings. Look for:
- Lean: Which way is the tree naturally leaning?
- Wind: How is the wind affecting the tree?
- Branches: Are there any dead or hanging branches that could fall unexpectedly?
- Obstacles: Are there any obstacles in the intended felling zone, such as power lines, buildings, or other trees?
- Escape Route: Plan a clear escape route that is 45 degrees away from the direction of the fall.
The Notch: The notch is a critical component of the felling cut. It determines the direction of the fall.
- Open Face Notch: A common type of notch, consisting of a horizontal cut and an angled cut that meet at a point. The angle of the notch should be about 45 degrees.
- Humboldt Notch: A variation of the open face notch, with a steeper angle. It’s often used for larger trees.
- Conventional Notch: The top cut is angled and the bottom cut is horizontal.
The Hinge: The hinge is a strip of wood left uncut between the notch and the back cut. It controls the fall of the tree.
- Hinge Width: The width of the hinge should be about 10% of the tree’s diameter.
- Hinge Placement: The hinge should be placed directly behind the notch.
The Back Cut: The back cut is made on the opposite side of the tree from the notch. It severs the remaining wood and allows the tree to fall.
- Leaving the Hinge: The back cut should be made slightly above the bottom of the notch, leaving the hinge intact.
- Using Wedges: Wedges can be used to help direct the fall of the tree and prevent the saw from getting pinched.
My Experience: I once witnessed a near-fatal accident when a logger failed to properly assess the lean of a tree. The tree fell in the opposite direction of the intended fall, narrowly missing him. It was a stark reminder of the importance of careful planning and assessment.
Data Point: According to the Occupational Safety and Health Administration (OSHA), tree felling is one of the most dangerous occupations in the United States. Careful planning and adherence to safety guidelines can significantly reduce the risk of accidents.
The Felling Cut in Action:
- Clear the Area: Remove any brush or debris from around the base of the tree.
- Establish Your Stance: Position yourself on the uphill side of the tree, if possible.
- Make the Notch: Use a smooth, controlled motion to make the horizontal and angled cuts of the notch.
- Make the Back Cut: Insert the saw on the opposite side of the tree from the notch, slightly above the bottom of the notch. Leave the hinge intact.
- Insert Wedges: If necessary, insert wedges into the back cut to help direct the fall of the tree.
- Retreat: As the tree begins to fall, retreat quickly and safely along your planned escape route.
Unique Insight: Practice your felling techniques on smaller trees before tackling larger ones. Start with trees that have a minimal lean and no significant obstacles.
Actionable Takeaway: Never underestimate the power of a tree. Always take the time to assess the situation, plan your cuts, and wear appropriate PPE. If you’re not comfortable felling a tree, hire a professional.
Example: You’re felling a pine tree with a slight lean to the east.
- Equipment Used: MS 661 Magnum, felling wedges, measuring tape, axe.
- Wood Type: Pine.
- Safety Considerations: Wear appropriate PPE, including a hard hat, safety glasses, hearing protection, gloves, and chaps.
- Process: Assess the tree for lean, wind, and obstacles. Clear the area around the base of the tree. Use the measuring tape to determine the tree’s diameter. Make an open face notch on the east side of the tree, with an angle of about 45 degrees. Make the back cut on the west side of the tree, slightly above the bottom of the notch, leaving a hinge that is about 10% of the tree’s diameter. Insert felling wedges into the back cut to help direct the fall of the tree. As the tree begins to fall, retreat quickly and safely along your planned escape route.
3. Bucking Like a Pro: Efficiency and Ergonomics
Bucking is the process of cutting a felled tree into smaller, more manageable lengths. It’s a physically demanding task, but with the right techniques, you can minimize fatigue and maximize efficiency.
Planning the Cuts:
- Determining Length: Decide on the desired length of the firewood or lumber.
- Avoiding Obstacles: Look for knots, branches, or other obstacles that could make cutting difficult.
- Supporting the Log: Ensure that the log is properly supported to prevent pinching the saw.
Bucking Techniques:
- Cutting from Above: This is the most common bucking technique, where you cut down through the log from above.
- Cutting from Below: This technique is used when the log is supported at both ends. You cut up through the log from below, meeting the cut from above.
- Boring: This technique is used to relieve tension in the log and prevent pinching. You insert the saw into the log at an angle and make a series of overlapping cuts.
My Experience: I used to struggle with bucking large logs, constantly fighting the saw and straining my back. Then, I learned the importance of proper support and cutting techniques. By using wedges and strategically placed cuts, I was able to buck logs with much less effort and fatigue.
Data Point: According to a study by the University of Oregon, using proper bucking techniques can reduce operator fatigue by up to 40%.
Ergonomics:
- Maintaining a Good Posture: Keep your back straight and your knees bent. Avoid twisting or reaching.
