Echo CS-500P

2-Stroke

The Echo CS-500P is a 50.2cc <!-- verify: echo-usa.com --> 2-stroke professional chainsaw designed for regular production cutting — firewood, land clearing, and medium-to-large tree felling with 18" to 20" guide bars. The P suffix indicates professional-grade build quality. It runs a Zama carburetor and features Echo's Vibration Reduction System and G-Force Engine Air Pre-Cleaner. Under professional production use, monthly fuel system service (filter, primer bulb, lines) and air filter maintenance are routine. A reliable choice for arborists who need professional power without moving to the larger CS-590 displacement class.
