The STIGA CS 540 chainsaw with 35 cm (14") bar is powered by a 38.5 cc (1.6 kW) engine, making it reliable and powerful yet lightweight. The magnesium engine cover ensures robustness, reliability and quick cooling. The oil pump is automatic and adjustable. Maintenance operations can be performed quickly and easily thanks to a number of features; such as the tool-less handle on the air filter cover without the need for additional tools, the tensioning wrench located under the rear handle and the fuel tank level monitoring window. The ergonomic soft-touch handle and spring system ensure reduced vibrations and greater comfort.
