Knowing these specifications is essential for matching the saw to the job and understanding its fuel consumption and maintenance requirements.
Hack #1: Mastering Chain Selection and Sharpening
The chain is arguably the most critical component of any chainsaw, and with the 661 C, getting the right chain and keeping it sharp is paramount.
Chain Selection: Matching the Chain to the Wood
Not all chains are created equal. Different chain types are designed for different purposes:
- Full Chisel: These chains have aggressive cutters and are ideal for clean wood. They cut quickly but dull faster in dirty or frozen wood.
- Semi-Chisel: A good all-around chain, offering a balance between cutting speed and durability.
- Low-Kickback: Designed with safety in mind, these chains are less prone to kickback but cut slower.
- Ripping Chain: Specifically designed for milling lumber, with cutters that slice parallel to the wood grain.
I’ve found that a full chisel chain works best for felling and bucking clean hardwood, while a semi-chisel chain is a better choice for processing firewood that might contain dirt or bark.
Data Point: A study by the Forest Products Laboratory found that using the wrong chain type can reduce cutting efficiency by up to 30%.
Chain Sharpening: The Key to Efficiency
A dull chain not only cuts slower but also puts more strain on the engine and increases the risk of kickback. Sharpening your chain regularly is crucial.
Cost Consideration: Professional chainsaw sharpening typically costs between $10 and $20 per chain. However, learning to sharpen your own chain can save you money in the long run.
Sharpening Tools:
- Round File and Guide: The most common and affordable method.
- Electric Chain Sharpener: More expensive but faster and more precise.
- Bar-Mounted Sharpener: Convenient for sharpening in the field.
Sharpening Technique:
- Secure the chainsaw in a vise.
- Use a round file of the correct diameter for your chain (typically 5/32″ or 3/16″).
- Follow the manufacturer’s recommended filing angles.
- File each cutter evenly, removing only a small amount of material each time.
- Check the depth gauges and file them down if necessary.
Personal Experience: I learned to sharpen my chains using a round file and guide. It took some practice, but now I can sharpen a chain in about 15 minutes. The key is to be consistent and pay attention to detail.
Hack #2: Optimizing Bar and Chain Oiling
Proper lubrication is essential for the longevity and performance of your chainsaw. Insufficient oiling can lead to premature wear of the bar and chain, increased friction, and even engine damage.
Choosing the Right Bar and Chain Oil
Use a high-quality bar and chain oil specifically designed for chainsaws. Avoid using motor oil or other substitutes, as they may not provide adequate lubrication and can damage the saw.
Cost Consideration: Bar and chain oil typically costs between $10 and $20 per gallon. Using a cheaper oil may seem like a good way to save money, but it can lead to more expensive repairs down the road.
Oil Types:
- Petroleum-Based Oil: The most common type of bar and chain oil.
- Vegetable-Based Oil: Biodegradable and environmentally friendly.
- Synthetic Oil: Offers superior lubrication and performance in extreme conditions.
I prefer to use a vegetable-based oil whenever possible, as it’s better for the environment and doesn’t leave an oily residue on the wood.
Adjusting the Oiler
The Stihl MS 661 C has an adjustable oiler, allowing you to control the amount of oil delivered to the bar and chain. Adjust the oiler based on the type of wood you’re cutting and the bar length you’re using.
Data Point: According to Stihl, proper oiling can extend the life of the bar and chain by up to 50%.
Oiler Adjustment Tips:
- For hardwoods, increase the oil flow.
- For softwoods, reduce the oil flow.
- When using a longer bar, increase the oil flow.
- When cutting in cold weather, use a thinner oil.
Checking Oiling:
To check if your chainsaw is oiling properly, hold the saw over a piece of cardboard and run it at full throttle. A visible spray of oil should appear on the cardboard.
Personal Experience: I once neglected to check the oil level in my chainsaw and ended up running it dry. The bar and chain overheated, and I had to replace them. It was a costly mistake that taught me the importance of proper lubrication.
