Echo CS-590 Timber Wolf chain size
59.8 cc firewood saw. Echo's manual specifies Oregon 72LPX chain, 3/8″ pitch; the standard 20″ bar takes 70 drive links at .050″ gauge.
The CS-590 Timber Wolf is Echo's 59.8 cc value firewood saw. Echo's operator manual is unusually direct about the chain: it specifies an Oregon 72LPX chain in 3/8″ pitch on a 7-tooth sprocket, with a 20″ bar standard and 16″, 18″, 24″ and 27″ bars optional. The 72 in the Oregon code already tells you the gauge — .050″ — and Echo sells the factory loop as part 72LPX70CQ for the 20″ bar.
