The Oleo Mac GS651 Chainsaw is designed for heavy and prolonged work in the most demanding conditions.
This professional grade saw is supplied with a 50cm (20″) guide-bar and is powered by a very high-capacity 64cc (4.7hp) engine that combines a two-ring piston with an optimised cylinder-design so as to ensure it can handle prolonged periods of high-RPM use.
- Casing in aluminium guarantees maximum resistance to stresses and ensures steady efficiency even with long chain bars.
- Generously proportioned filtration surface affords optimum engine protection even in heavily dust-laden environments, prolonging useful life.
- Special cylinders and pistons with two rings are designed to withstand intensive and prolonged use over time.
- Incorporates on board clutch with drum and brake belt built into the crankcase. This prevents the ingress of foreign matter between the centrifugal weights, ensuring consistently perfect operation and facilitating disassembly of the chain guard.
- Equipped with the anti-vibration system using two spring dampers and four rubber stops, significantly isolating the operator from engine vibration for greater comfort during use.
- Equipped with multifunction lever (choke/ start/ stop controls integrated in a single conveniently located lever to simplify starting and switching off the machine), decompressor and side chain tensioner.
