Developed to fit the needs of a wide range of users the Oleo-Mac GS 451 petrol chainsaw can be bought with either a 16" or 18" Bar and chain for limbing, pruning and cutting medium diameter trunks. Compactness, versatility and an excellent power-to-weight ratio ensure excellent cutting performance for all types of use. Primer, on/off lever/multi-function choke, aluminium oiler, hybrid anti vibration system (3 springs + 2 rubber mounts), “EasyOn”: just so me of the advanced technical solutions that assure the best possible performance in conditions of the maximum comfort and safety.


• Piston with 2 rings, forged and machined steel crankshaft, needle roller bearings, nickel plated cylinder: guaranteed constant efficiency through time, even in the case of heavy duty use

• High cutting speed (better than 17 m/s): fast, clean and accurate cutting action, without damaging the tree.

• Primer Device: boosts the fuel flow to the carburettor to facilitate cold starts, starts after refuelling, and starts after long periods of disuse.

• Nylon filter: longer filter servicing intervals thanks to the large filtration surface

• Lateral chain tensioner: simplifies tensioning adjustments while avoiding any risk of contact with the chain. The fixing nuts, which are integral with the chain guard, allow easier fastening because they can’t be lost

• Aluminium oiler: facilitates the job of the operator by allowing the oil feed to be varied to suit the workload on the machine and the bar/chai n combination. Zero oil flow with the engine at idling speed ensures lower consumption and reduced environmental impact.

• Side handle covering in nonslip material: enhanced grip during use of the tool. • Anti-vibration system with 3 spring dampers and 2 rubber mounts: interposed between handle and engine support, the anti-vibration system keeps the operator’s hands and body fully isolated from machine vibrations for the maximum comfort.
