Main features of the machine
The piston is made up of two elastic rings, the crankshaft, the forged and turned steel connecting rod and the needle cage. The nickel-plated cylinder ensures optimal and continuous performance even under heavy use. With a cutting speed of more than 17 m / s, it allows much faster and more precise cuts without damaging the plant. | |
In order to optimize combustion, achieve greater power and reduce noise and pollutant emissions to a minimum, the discharge and exhaust windows have been studied and optimized. | |
The grapefruit air filter cover allows quick access to the ICE DEVIC system and inspecting or replacing the spark plug or filter with little use of tools. With this we will achieve a much more simplified maintenance. | |
The PRIMER device pumps the mixture into the carburetor, thus aiding cold start-up, after each tank filling or long periods of inactivity | |
Thanks to a large filtering surface, an increase in working autonomy hours is achieved between each filter cleaning. | |
“EASY ON” system to help reduce kickback at startup. | |
On / off switch and the semi-throttle control integrated into a single multifunctional lever that guarantees practicality and simplicity of use. | |
Double removable steel and plastic harpoon guarantees a secure hook on the trunk providing greater stability and control over the chainsaw when making cuts. | |
The side chain tensioner prevents any risk of contact with the chain. The nuts that lock the bar are part of the chain cover, making it easier to adjust the chain, preventing it from losing or falling. | |
Adjustable aluminum oil pump allows the user to vary the oil flow in relation to the use made of the chainsaw as well as the length of the chain. With the engine idling, the pump does not send oil so it guarantees lower consumption and greater care for the environment. | |
Fuel tank mixes with external indicator that helps when refilling. | |
Side handle covered with non-slip material that improves grip when using the chainsaw. The chainsaw is equipped with an anti-vibration system consisting of 3 spring and 2 rubber shock absorbers placed between the handle and the motor support that protect the operator from vibrations, offering greater comfort in using the machine. |
