A chainsaw is a portable handheld power saw that cuts with a set of teeth attached to a rotating chain driven along a guide bar. Modern chainsaws are typically gasoline or electric and are used in activities such as tree felling, limbing, bucking, pruning, cutting firebreaks, harvesting firewood, and cutting ice.
Components & Operation
A chainsaw comprises an engine, a drive mechanism, a guide bar, a cutting chain, a tensioning mechanism, and safety features. Various safety practices and working techniques are used with chainsaws. Precursors to modern chainsaws were first used in surgery, with patents for wood chainsaws beginning in the late 19th century.
Safety Standards
Chainsaws are among the most hazardous portable power tools in professional use. Kickback — the sudden upward rotation of the bar — is the leading cause of chainsaw injury. Modern saws include chain brakes, low-kickback chains, and hand guards. Personal protective equipment including chainsaw chaps, helmet, and gloves is mandatory for professional use.
Professional vs Consumer Use
Consumer-grade chainsaws are suitable for firewood and basic yard maintenance. Professional arborist saws are built for extended use, high-torque cutting, and compatibility with rigging operations. Many felling, climbing, and removal tasks legally require trained operators with current certification.
