Stihl 170 Chain Guide (5 Expert Tips for Perfect Woodcutting)
In recent years, I’ve noticed a significant shift in how people approach woodcutting, especially with smaller chainsaws like the Stihl 170. There’s a growing emphasis on efficiency, safety, and maximizing the use of every log. More folks are seeking sustainable practices, aiming to get the most heat from their firewood while minimizing environmental impact. I’ve seen a surge in interest in optimizing workflows, from felling the tree to stacking the split wood, and that’s what I’m here to talk about. Let’s dive into how to master the Stihl 170 and achieve perfect woodcutting.
Stihl 170 Chain Guide: 5 Expert Tips for Perfect Woodcutting
The Stihl 170 is a fantastic little chainsaw, perfect for homeowners and anyone tackling smaller jobs. But even with a great tool, technique is everything. Over my years working with wood, I’ve learned that a few key adjustments can make a world of difference. So, let’s get into my five expert tips to make your Stihl 170 sing.
1. Mastering Chain Maintenance: The Key to Efficiency
Chain maintenance is, without a doubt, the most crucial aspect of using any chainsaw, and the Stihl 170 is no exception. A dull chain is not only inefficient; it’s also dangerous. It can lead to kickback, uneven cuts, and increased strain on both you and the saw.
- Sharpening Frequency: I recommend sharpening the chain after every two to three tanks of fuel, or whenever you notice a decrease in cutting performance. A sharp chain will pull itself through the wood, creating nice, even chips. A dull chain will produce sawdust and require you to force the saw, which is a big no-no.
- Sharpening Tools: You can use a file and guide, or an electric chain sharpener. I personally prefer the file and guide for on-the-go sharpening in the field. It gives you more control and helps maintain the correct angle. A good file and guide kit is inexpensive and a worthwhile investment.
- Sharpening Technique: The correct angle and depth are crucial. Stihl chains typically have specific angles marked on the chain itself. Use these as your guide. I always start by filing the cutters on one side of the chain, then flipping the saw to do the other side. Maintain consistent pressure and stroke length for each cutter.
- Depth Gauge Adjustment: Don’t forget about the depth gauges! These small protrusions in front of each cutter control how much the cutter bites into the wood. As you sharpen the cutters, the depth gauges will need to be filed down slightly to maintain the correct relationship. A depth gauge tool is essential for this.
Data Point: Studies have shown that a properly sharpened chain can increase cutting efficiency by up to 30%. That translates to less time spent cutting wood and less fuel consumed.
My Story: I once spent an entire day trying to fell a small tree with a dull chain. I was exhausted, frustrated, and getting nowhere fast. Finally, I took the time to properly sharpen the chain, and the difference was night and day. The tree came down in minutes, and I learned a valuable lesson about the importance of chain maintenance.
2. Choosing the Right Bar and Chain: Maximizing Performance
The standard bar and chain that comes with the Stihl 170 are generally suitable for most tasks. However, depending on the type of wood you’re cutting and the size of the logs, you might consider upgrading or using a different type of chain.
- Bar Length: The Stihl 170 typically comes with a 16-inch bar. This is a good all-around length, but if you’re primarily cutting smaller logs, a 14-inch bar might be more maneuverable. Conversely, if you’re occasionally dealing with larger logs, you could consider an 18-inch bar, but be mindful of the saw’s power limitations.
- Chain Type: There are different types of chains available, each designed for specific purposes.
- Full Chisel: These chains have aggressive cutters and are best for cutting clean, softwood. They require more frequent sharpening but offer the fastest cutting speeds.
- Semi-Chisel: These chains are more durable and can handle dirtier wood. They’re a good compromise between cutting speed and longevity.
- Low-Profile: These chains are designed for safety and are less prone to kickback. They’re a good choice for beginners or for cutting in tight spaces.
- Matching Bar and Chain: Ensure that the bar and chain are compatible. The chain’s pitch (the distance between rivets) and gauge (the thickness of the drive links) must match the bar’s specifications.
Data Point: Using the wrong chain type can reduce cutting efficiency by as much as 20% and increase the risk of kickback.
Expert Quote: “The chain is the only part of the chainsaw that actually cuts the wood, so it’s crucial to choose the right one for the job,” says Arnie Green, a seasoned logger from Oregon.
My Story: I once tried to cut through some knotty oak with a full chisel chain that was designed for softwood. The chain dulled almost instantly, and I ended up spending more time sharpening than cutting. I switched to a semi-chisel chain, and the difference was remarkable.
3. Perfecting Your Cutting Technique: Safety and Efficiency
Safe and efficient cutting techniques are essential for maximizing the performance of your Stihl 170 and minimizing the risk of injury.
- Stance and Grip: Maintain a firm grip on the saw with both hands. Keep your feet shoulder-width apart and your weight balanced. Avoid reaching or overextending yourself.
- Starting the Cut: Always start the cut with the bottom of the bar, using the bumper spikes to pivot the saw into the wood. This provides more control and reduces the risk of kickback.
- Cutting Pressure: Let the saw do the work. Don’t force it. Apply gentle, consistent pressure and allow the chain to pull itself through the wood.
- Avoiding Pinching: Pinching occurs when the bar gets stuck in the wood. To avoid pinching, use wedges to keep the cut open. If the bar does get pinched, stop the saw immediately and use a wedge or another tool to free it.
- Felling Techniques (for small trees):
- Planning: Always assess the tree and its surroundings before felling. Identify the lean of the tree, any obstacles in its path, and escape routes.
- Notch Cut: Cut a notch on the side of the tree in the direction you want it to fall. The notch should be about one-third of the tree’s diameter.
- Back Cut: Make a back cut on the opposite side of the tree, slightly above the bottom of the notch. Leave a hinge of wood to control the direction of the fall.
- Felling: Use wedges to help guide the tree’s fall. Once the tree starts to fall, move away quickly along your planned escape route.
Data Point: Proper felling techniques can reduce the risk of accidents by up to 50%.
My Story: I once witnessed a near-miss when a friend was felling a small tree. He didn’t properly assess the lean of the tree, and it fell in the opposite direction of where he intended. Luckily, no one was hurt, but it was a sobering reminder of the importance of proper planning and technique.
4. Optimizing Fuel and Lubrication: Extending Saw Life
Proper fuel and lubrication are crucial for maintaining the health and extending the lifespan of your Stihl 170.
- Fuel Mixture: The Stihl 170 requires a 50:1 fuel-to-oil mixture. Use a high-quality 2-cycle engine oil specifically designed for chainsaws. Mix the fuel and oil in a separate container before adding it to the saw’s fuel tank.
- Chain Oil: Use a high-quality bar and chain oil to lubricate the chain. This will reduce friction, prevent overheating, and extend the life of the chain and bar. I prefer a bar and chain oil with tackifiers, which help the oil cling to the chain.
- Oil Level: Check the oil level frequently and refill as needed. A properly lubricated chain will throw off a fine mist of oil while cutting. If the chain is dry, it’s not getting enough oil.
- Fuel Storage: Store fuel in a properly labeled container in a cool, dry place. Fuel can degrade over time, so it’s best to use it within a few months.
Data Point: Using the correct fuel mixture and bar and chain oil can extend the life of your chainsaw by up to 25%.
Expert Quote: “Using the right fuel and oil is like giving your chainsaw a healthy diet,” says Martha Jones, a small engine mechanic with over 30 years of experience. “It will keep it running smoothly and prevent costly repairs down the road.”
My Story: I once neglected to check the oil level on my chainsaw, and the chain ran dry. The bar overheated and warped, and the chain was ruined. It was a costly mistake that could have been easily avoided.
5. Smart Storage and Transportation: Protecting Your Investment
Proper storage and transportation are essential for protecting your Stihl 170 and keeping it in good working order.
- Cleaning: After each use, clean the saw thoroughly. Remove any sawdust, debris, or oil buildup. Use a brush and a solvent to clean the bar and chain.
- Bar and Chain Cover: Always use a bar and chain cover when storing or transporting the saw. This will protect the chain from damage and prevent accidental cuts.
- Storage Location: Store the saw in a dry, well-ventilated place. Avoid storing it in direct sunlight or extreme temperatures.
- Fuel Drain: If you’re not going to use the saw for an extended period, drain the fuel tank. This will prevent the fuel from degrading and causing problems.
- Transportation: When transporting the saw, secure it properly in your vehicle. Use straps or a carrying case to prevent it from moving around and getting damaged.
Data Point: Proper storage and transportation can prevent up to 15% of chainsaw repairs.
My Story: I once left my chainsaw in the back of my truck overnight, and it rained. The saw got soaked, and the carburetor rusted. It took me several hours to clean and repair it. Now, I always make sure to store my saw in a dry place.
