käsikäivitusega

Käsikäivitusega refers to a method of starting an engine or machine by manual means. This typically involves a direct physical action by the operator to initiate the operation. Common examples include hand-cranking a small engine, pulling a starter cord on a lawnmower, or manually turning a crank to begin the operation of a piece of machinery. The term emphasizes the direct human involvement in the initial activation process, as opposed to automated or remote starting systems.

Historically, many engines and machines relied solely on käsikäivitusega for their operation. This was often due to limitations in electrical technology or the absence of more complex starting mechanisms. While advancements have led to more sophisticated starting methods, käsikäivitusega remains prevalent in certain applications where simplicity, cost-effectiveness, or independence from external power sources are prioritized. Such methods can require physical exertion and skill from the operator. In some contexts, it may be a backup system in case of failure of the primary electric start. The design of a käsikäivitusega system often involves a lever, crank, or cord that engages with a mechanism on the engine or machine, transferring the operator's energy to overcome inertia and begin the cycle of operation.
