Buying Guide
Key Purchase Considerations
When selecting an 18 inch chain, the most critical factors are pitch, gauge, drive links, and the chain’s design. The pitch affects how the chain engages the bar and the saw’s power delivery, while the gauge influences durability and chain tensioning. Drive links must match the bar length and the number stamped on the side of the bar. Semi-chisel designs are common for general-purpose use, offering a blend of cutting speed and ease of sharpening. Consider the chain’s steel quality, heat treatment, and rivet durability for long-term reliability.
Compatibility And Fit
Always confirm the chain matches your bar’s 18 inch length, pitch, gauge, and drive link count. Some brands use 0.325 inch pitch, which differs from the more common 3/8 inch LP. Use the bar’s side stamp and user manual to verify fit, or contact the manufacturer’s support. If you switch brands, ensure you select a chain with the same drive link count and gauge to avoid tensioning problems. A well-matched chain improves cutting efficiency and reduces the risk of chain derailment during heavy use.
Performance And Safety
Low kickback and low-vibration chains are increasingly common and beneficial for reducing operator fatigue. Always operate chainsaw equipment with proper safety gear and follow manufacturer guidelines for tensioning and lubrication. A chain designed for high-precision cuts and consistent lubrication helps keep the bar and chain cooler, extending life and performance. Periodically inspect the chain for damaged rivets or bent drive links, and replace as needed to maintain even cutting action.
Maintenance And Installation
Install with the bar clean and free of debris, lubricate the chain as recommended by the saw manufacturer, and tension it according to the bar and chain instructions. After installation, run the saw briefly to seat the chain, then re-tension if necessary. Sharpening intervals depend on use, but routine checks for dull teeth and missing cutters keep cutting efficiency high. Store replacement chains in a dry place to prevent corrosion and ensure the chain remains rust-free until next use.
