Stihl chainsaws are powerful tools for a variety of tasks, from felling trees to clearing brush. However, incorrect chain direction can lead to easy kickback and other serious damage to the woods and even you. When installing the new chain, make sure to keep the chain pointed in the clockwise direction for smooth operation. In this guide, we’ll delve into the intricacies of Stihl chainsaw direction and other useful knowledge you need to know with your Stihl chainsaw.
Understanding Stihl Chainsaw Chain
Knowing the chainsaw chain components is essential for parts sourcing and routine maintenance. The picture below shows a diagram of common Stihl chainsaw chain components:
- Top Plate: The flat, top surface of the cutter that slices through the wood fibers horizontally.
- Cutter: The entire cutting tooth assembly that is responsible for carving and removing wood.
- Depth Gauge: The raised guard in front of the cutter that regulates how deep the cutting edge bites into the wood.
- Gullet: The curved clearance area between the depth gauge and the cutting edge that captures and clears out wood chips.
- Rivet: The cylindrical metal pin that holds the links and tie straps together, acting as a hinge for the chain.
- Tooth Body: The main chassis or base structure of the cutting link that supports the cutter and depth gauge.
- Drive Link: The bottom triangular link that fits into the guide bar groove and engages with the engine’s sprocket to drive the chain.
- Heel: The rear bottom corner of the cutter link’s chassis that rides along the guide bar.
- Toe: The front bottom corner of the cutter link’s chassis that leads the link along the guide bar.
- Tie Strap: The flat side-connecting plate used to join the drive links and cutter links together.
Stihl Chainsaw Chain Direction
Getting your Stihl chain on in the right direction is super easy.
Most chainsaw chains are designed to rotate clockwise when viewed from the rear of your Stihl chainsaw. On the top of the bar, the cutter must be facing the tip of the bar/blade, while on the bottom of the bar, the cutter must be facing the powerhead. The cutter is the part that cuts the wood and the depth gauge is shorter than the cutter. A chainsaw chain spins out from the top of the saw around the bar’s tip and back under towards the powerhead.
Here’s one simple rule: make sure your Stihl chain is pointed in the clockwise direction. It looks like the cutting edge of the teeth is going away from you when they are on the top of the bar and towards you when they get around the nose and into the bottom side of the bar.
Importance of the Correct Stihl Chain Direction
Your Stihl chainsaws utilize a rotating chain to cut through wood. The Stihl chain consists of sharp teeth driven by a sprocket located on the chainsaw’s engine. Correct Stihl chainsaw chain direction is crucial for several reasons below:
- Safety: A properly installed chain helps prevent kickback. It refers to the situation where the chain binds in the wood and suddenly throws the saw backwards.
- Cutting Efficiency: A correct chain direction ensures smooth and efficient cuts.
- Chain Wear: Incorrect chain direction can lead to uneven wear on the chain teeth, reducing their lifespan.
- Friction and Heat: A reversed chain fails to cut, leading to extreme friction and heat that can damage the guide bar, produce fine powdery dust instead of healthy wood chips, and pose serious safety risks.
How to Install Your Stihl Chainsaw Correctly?
Proper installation of the Stihl chain is crucial for ensuring a safe and effective cutting operation. Here are general steps for you to follow:
- Safety First: Always disconnect the spark plug wire before working on your chainsaw.
- Remove the Bar and Chain: Follow the manufacturer’s instructions to remove the bar and chain from the saw.
- Inspect the Chain: Check the chain for any wear and replace it when necessary.
- Position the Chain on the Bar: Align the chain with the bar’s grooves, ensuring the drive links engage with the sprocket.
- Secure the Chain: Tighten the chain tensioning screws to the manufacturer’s specifications.
- Reinstall the Bar and Chain: Carefully reinstall the bar and chain onto the saw, ensuring they are properly aligned.
- Reconnect the Spark Plug Wire: Once the chain is installed, reconnect the spark plug wire.
- Checking Chain Rotation Direction: Start the chainsaw and observe the chain’s movement. The chain should rotate in the clockwise direction when viewed from the rear of the saw.
Conclusion
Installing your Stihl chain in the correct direction is crucial for the smooth operation and even the life expectancy of your chainsaw. For this purpose, always keep the directional arrow on your Stihl chain pointed in the clockwise direction. After installation, it’s a must to check the chain rotation direction.
