The Echo CS-100 chainsaw was manufactured by Echo (Kioritz Corporation) in Tokyo, Japan and was introduced in 1965. It was discontinued in 1966, but during its short production period, it proved to be a reliable and powerful tool. The chainsaw boasted an impressive 102cc engine displacement, making it one of the larger saws of its time. Its rigid handlebar system and one-man operator configuration made it easy to handle, while its die-cast magnesium construction made it durable and long-lasting.
Though it may not be in production anymore, the Echo CS-100 chainsaw remains a testament to the quality and engineering of Echo products.
