When using a .404'' Chipper Saw Chain, how do I adjust the chain tension based on the wood type for the best cutting results?

When using a 404'' Chipper Saw Chain, adjusting the chain's tension based on the wood type can significantly affect cutting results and the chain's lifespan. Here are some suggestions for adjusting chain tension to suit different wood types:

1. Soft wood (such as pine, fir, etc.)
Recommended Tension: When cutting soft wood, the chain tension can be slightly relaxed. A looser chain reduces cutting resistance, allowing the chain to pass through the wood more easily, while also reducing overheating and wear on the chain during the sawing process.
Adjustment method: When adjusting the chain tension, make sure the chain can slide easily on the guide plate but does not come away from the guide plate. Gently lift the chain with your hands, making sure the chain can lift about 1/8 inch from the guide plate.
2. Hard wood (such as oak, maple, etc.)
Recommended Tension: Hard wood requires higher cutting force, so the chain tension should be increased appropriately. Tighter chains reduce the risk of chain skipping and help cut hardwood more accurately without the chain slipping or getting stuck.
Adjustment method: When cutting hardwood, the tension of the chain should make the chain fit tightly with the guide plate, but still allow manual sliding. When you lift the chain, it should just clear the guide plate, leaving about 1/16 inch of clearance.
3. Wet wood
Recommended tension: Wet wood is relatively sticky and tends to increase cutting resistance. Therefore, the chain tension should be slightly looser to prevent the chain from expanding and becoming loose due to overheating due to friction.
Adjustment method: Loosen the chain to moderate tension so that the chain can slide freely. When you lift the chain, it should make slight contact with the edge of the guide plate, but not completely separate.
4. Frozen wood
Recommended tension: Frozen wood is more difficult to cut due to its increased hardness, and the chain requires higher tension to ensure cutting stability and accuracy.
Adjustment method: Appropriately increase the tension of the chain and ensure that the chain is close to the guide plate to prevent the chain from slipping during high-intensity cutting. There should be almost no noticeable gap when you lift the chain.
5. Wood with uneven density (such as scarred wood)
Recommended Tension: For wood with uneven density, such as knotted wood, it is recommended to use a slightly tighter chain tension to prevent the chain from jumping or losing control when cutting hard knots.
How to adjust: The chain tension should be slightly higher than the regular setting, but still maintain chain slideability. When lifting the chain, keep it in close contact with the guide plate.
6. Other matters needing attention
Ambient temperature: At high temperatures, the chain will become loose due to thermal expansion; at low temperatures, the chain will shrink. Therefore, the chain tension should be adjusted in time according to the ambient temperature to ensure that the chain is not excessively loose or overtight during use.
Inspection before operation: Check the chain tension before each start of operation, and check and adjust regularly after long-term operation to ensure that the chain is always in the best tensioned state.
