Everything you need to know about a chainsaw chain!
Saw Chain Terminology
If you want to get the most out of your chainsaw, it’s important that you choose the right chainsaw chain. Before choosing a chainsaw chain, here is something you first need to know, such as the pitch, the gauge, the number of drive links...Once you’ve learned these, everything else about the choice is basically about what you prefer.
Front Hand Guard: The front handle for holding the chainsaw.
Safety Throttle: Safety mechanism to prevent accidental throttle acceleration.
Pull Starter: The recoil starter is used to start gas engines.
Throttle: The throttle trigger controls the power of the engine.
Bumper Spikes: Used to rest the chainsaw against the wood as it cuts. It helps to prevent kick-back.
Saw Chain: The saw chain wraps around the guide bar and has cutters for cutting through wood.
Guide Bar: The long steel bar that guides the cutting saw chain.
Chain Brake: A safe device to stop the saw chain immediately if kick-back occurs.
Choke: The choke works by adjusting the flow of air which affects the fuel-air mixture to get the engine running.
Kickback Danger Area: Kickback happens most often when using the nose of the chainsaw to cut wood. The rotation of the saw and cutting chain catches the wood in such a way that causes the nose of the chainsaw to shoot upwards, towards your upper body and head.
4 Basic Components
① Cutter: full-chisel, semi-chisel, low-profile
③ Tie Strap
④ Drive Link: the teeth on the bottom of your chain that slot into the groove of your bar
How to Choose the Right Saw Chain
To target the right chainsaw chain, you need to learn the followings:
① Bar Length:The exposed length of the guide bar.
② Pitch:The distance between any three rivets divided by two.
③ Gauge:The thickness of the drive links.
④ Drive Links:The actual number of links on your old chainsaw chain.
Semi-Chisel: The semi-chisel cutters ensure you stay sharp longer in different cutting conditions. It's easy to sharpen with low maintenance to make your work easy.
Full-Chisel: The full-chisel cutters are designed with square-cornered teeth for high aggressiveness in cutting. If you require top performance during a long day of logging, a full-chisel saw chain is a smart choice for you.
Standard Sequence: The Full House or Standard saw chain features the most teeth which make for extremely smooth cuts but does not cut wood as quickly as a full skip or sem-skip. It is used on a chainsaw that features a guide bar up to 24 inches and is best suited for situations that require a clean finish like timber used for building.
Semi-Skip Sequence: The semi-skip chain is a mid-grade chain arrangement, with teeth arranged by one or two links between the cutters. The semi-skip chain doesn’t cut as fast as the full skip, but it offers a solid balance between power and efficiency with much smoother cuts.
Full-Skip Sequence: The full skip chain features fewer teeth and is extremely efficient for cutting. It’s best suited for larger chainsaws with a bar size over 24 inches. Due to their faster operational speed and arrangement of teeth, they can cut faster but aren’t as smooth. So, it’s efficient for cutting firewood, cutting limbs, and other tasks where smoothness isn’t important.
