Arnold 41AY4218766 Gas Chainsaw 42cc 18 Inch 2-cycle

Product Description

The ARNOLD 41AY4218766 is a 42cc full-crank 2-cycle gas-powered chainsaw designed for residential cutting tasks including limbing, bucking, and felling small to medium trees. The engine features SpringAssist technology for smoother pull starts. An 18-inch low-kickback bar and chain delivers controlled cuts through hardwood and softwood alike. Metal bucking spikes provide additional stability and cut control during use. An adjustable automatic oiler continuously lubricates the bar and chain, extending wear life and maintaining consistent cutting performance. At 15.55 pounds, the saw is light enough for extended overhead and ground-level work.

This chainsaw suits residential property owners and light-duty arborist or landscaping crews needing a compact, easy-starting gas saw for seasonal maintenance, storm cleanup, and firewood processing. The tool-free air filter and spark plug access simplifies routine maintenance between jobs. A side-access chain tensioner allows quick tension adjustment without additional tools. The full wrap-around aluminum handle paired with a 3-point anti-vibration system reduces operator fatigue during extended cutting sessions. A resin bar guard with nesting capability is included for safe transport and storage. 2-cycle engine oil is included with the unit.

Always disable the chain brake and confirm the saw is fully stopped before adjusting chain tension or servicing the air filter and spark plug.
