Developed to satisfy the needs of a wide range of users, from homeowners for small scale pruning and limbing activities, cutting small and medium diameter trunks and general firewood cutting duties, to groundcare professionals 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 antivibration 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.
Engine transfer ports, exhaust port and silencer designed
to ensure optimum combustion and high power output while significantly reducing pollutant emissions and noise levels.
In particular, the cylinder of model GS 451 has been optimized to achieve a significant reduction in fuel consumption
Filter cover with knob: allows rapid and tool-free access to
the Ice device system, inspection and replacement of the air
filter, and access to the spark plu g (easy servicing).
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
EasyOn starting system: reduced recoil kick-backs during
engine starts
On/off switch, choke and half-throttle control incorporated into a single multifunction lever: guarantees practical
and simple use of the tool.
Plastic or steel double bucking spike (removable): guarantees a secure anchorage on logs or branches, giving greater
stability and better blade control during the cut.
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 cant 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.
Fuel tank with externally visible level: easier management
of refuelling stops.
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 operators hands and
body fully isolated from machine vibrations for the maximum comfort.
