Chainsaw 660 Guide: 5 Pro Tips for Maximizing Woodcutting

The Stihl MS 660 is a beast, no doubt about it. But a beast needs to be tamed, understood, and cared for if you want it to perform at its best. These aren’t just random tips; they’re hard-earned lessons from years of experience, and they’re designed to help you get the most out of your investment.

1. Chain Selection: Matching the Teeth to the Task

Choosing the right chain for your MS 660 is like choosing the right tires for your truck – it makes a world of difference. I’ve seen guys struggle with dull chains or the wrong type, wasting time and energy. Don’t be that guy.

Types of Chains:
- Full Chisel: Aggressive cutting, ideal for clean wood. Requires more frequent sharpening.
- Semi-Chisel: More forgiving in dirty or knotty wood. Holds an edge longer than full chisel.
- Low-Profile (Micro-Chisel): Less aggressive, suitable for smaller jobs and users with less experience.
- Skip Tooth: Fewer teeth for faster cutting of large diameter logs but a rougher finish.
- Matching the Chain to the Wood:
- For softwood like pine or fir, a full chisel chain will slice through with ease.
- For hardwood like oak or maple, a semi-chisel chain will hold up better against the increased density and potential for hidden debris.
Chain Pitch and Gauge:
- Ensure the chain pitch and gauge match your MS 660’s specifications. Using the wrong size can damage the saw and be dangerous.
- My Experience:
I remember one time, I was cutting a massive oak log with a full chisel chain. The chain was getting dull quickly, and the saw was bogging down. I switched to a semi-chisel chain, and the difference was night and day. The saw cut through the oak like butter, and the chain held its edge much longer. * Data Point:

According to a study by the Forest Products Laboratory, using the correct chain type can increase cutting efficiency by up to 20% and reduce fuel consumption by 10%. * Actionable Tip:

Keep a selection of chains on hand, and choose the right one for the job. Don’t be afraid to experiment to see what works best for you.

I once used the wrong fuel mixture in my MS 660, and it caused the engine to seize up. It was a costly mistake. Now, I’m meticulous about my fuel and oil. I always use the correct mixture ratio, and I use a high-quality bar and chain oil. * Data Point:

According to Stihl, using the correct fuel and oil can extend the life of your chainsaw by up to 50%. * Actionable Tip:

Always use the fuel and oil recommended by Stihl. Mix your fuel carefully, and store it in a properly labeled container.

4. Felling Techniques: Mastering the Art of the Drop

Felling a tree is a dangerous task, and it should only be attempted by experienced users. Understanding proper felling techniques is crucial for your safety and the safety of those around you.

Planning the Fell:
- Assess the tree for lean, wind direction, and any potential hazards.
- Clear the area around the tree of obstacles.
- Plan your escape route.
- Making the Cuts:
- The notch cut should be at a 45-degree angle and should be about one-third of the tree’s diameter.
- The back cut should be level and should leave a hinge of wood to control the direction of the fall.
- Using Wedges:
- Use wedges to prevent the tree from pinching the saw and to help direct the fall.
- My Experience:
I’ve felled hundreds of trees, and I’ve learned that planning is everything. Before I even start my saw, I spend time assessing the tree and the surrounding area. I make sure I have a clear escape route, and I use wedges to control the fall. * Data Point:

According to the Occupational Safety and Health Administration (OSHA), improper felling techniques are a leading cause of logging accidents. * Actionable Tip:

Take a felling course from a qualified instructor. Practice your felling techniques in a safe and controlled environment.

5. Workflow Optimization: Cutting Smarter, Not Harder

Woodcutting is hard work, but it doesn’t have to be backbreaking. By optimizing your workflow, you can reduce fatigue, increase efficiency, and get more done in less time.

Log Handling:
- Use log tongs or a cant hook to move logs safely and efficiently.
- Stack logs in a way that allows for good airflow and easy access.
- Bucking Techniques:
- Use a sawhorse to support logs while bucking them.
- Cut logs to the desired length with minimal waste.
- Splitting Techniques:
- Use a hydraulic log splitter for large or difficult-to-split logs.
- Use a splitting maul or axe for smaller logs.
- My Experience:
I used to just randomly pile logs wherever I could find space. It was a mess, and it made it difficult to access the wood when I needed it. Now, I stack my logs neatly in rows, with plenty of space between the rows for airflow. It’s made a huge difference in my efficiency. * Data Point:

A study by the University of Maine found that optimizing log handling can increase productivity by up to 25%. * Actionable Tip:

Take the time to plan your workflow and optimize your workspace. A little organization can go a long way.
