Chainsaw
Echo CS-590 Timber Wolf
2-Stroke
The Echo CS-590 Timber Wolf is a 59.8cc 2-stroke chainsaw and the highest-displacement consumer/prosumer model in Echo's CS lineup. The Timber Wolf name reflects its intended use in demanding timber work — large-diameter felling and bucking — with 18" to 24" guide bars. It runs a Zama carburetor and features Echo's Vibration Reduction System and G-Force Engine Air Pre-Cleaner. At this displacement, bar and chain condition are critical to both performance and operator safety. Fuel system service (filter, primer bulb, lines) and annual carburetor inspection are the primary service requirements.
