Where to buy

The CS-501SXH is the heated handle version of the CS-501SX. The heated handle is ideal for working in cold temperatures, providing extra comfort (function can be switched off when not required). This model weighs in at 0.2kg heavier than its counterpart, at just 5.9kg it is industry leading in terms of power to weight ratio. All other aspects of the 2 models are the same, the 50.2cm³ professional grade engine outputs an impressive 2.57kW making this a chain saw that punches way above its weight.
