The Echo CS-452VL is a mid-size professional chainsaw produced by ECHO Kioritz from 1975 to 1983, designed for reliable farm, forestry, and general woodcutting work.
Powered by a 44.3 cc air-cooled two-stroke engine, it features anti-vibration mounts, automatic chain oiling with manual override, and durable magnesium construction. Known for its balance of power and manageable weight, the CS-452VL became one of ECHO’s dependable workhorse saws of the late 1970s and early 1980s.

Just received one of these “Echo” chain saws, in pretty good condition. Needed some stats on oil/gas mix. Good web page to save. Thanks.
