 |
3-piece forged steel crankshaft, machined and balanced. Diamond aluminum piston with two sealing rings, cast iron connecting rod, two roller cages. Nickel coated cylinder. Metal engine block as a guarantee of high performance, strength and durability. |
 |
Carburetor support with four anti-vibration mounts. This guarantees a stable carburetion in any working situation and longer carburetor life. Large nylon filter and air pre-filtering system with labyrinth. This is to protect the machine in very dusty environments. |
 |
Electronic coil, flywheel with new fin profile and redesigned starter housing with wide intake slots. It offers a more regular engine operation and better cooling of the thermal unit at any engine speed, even at high ambient temperature. |
 |
INBOARD" clutch with bell and brake band integrated in the block. It prevents the introduction of foreign bodies between the centrifugal masses to avoid damage and malfunctions, facilitates the disassembly of the chain housing and simplifies cleaning and routine maintenance. |
 |
On/off switch, choke and semi-acceleration control integrated in a multifunction lever. Ensures easier and more practical use. |
 |
Decompression valve. This reduces the pressure in the explosion chamber to facilitate hot or cold engine starting. |
 |
Chain tensioner in lateral position. This facilitates chain adjustment by avoiding direct contact with the chain. |
 |
Filter cover with two lateral elastic fasteners, removable without tools for easy inspection. |
 |
Anti-vibration system with six dampers, two spring dampers and four rubber dampers. These are located between the control handle and the engine block. It completely isolates the operator from vibrations, with a significant reduction in fatigue. |
 |
Ergonomic controls: all machine functions are easily controlled with the right hand, without removing the hand from the handle. |
 |
Flywheel with new fin profile and redesigned starter housing with wide intake slots. It has a more regular engine operation and better cooling of the thermal group at any engine speed, even at high ambient temperature. |
 |
Reinforced silencer designed to reduce noise emission even at maximum speed. |
 |
INBOARD" clutch with bell and brake band integrated in the block. It prevents the introduction of foreign bodies between the centrifugal masses to avoid damage and malfunctions, facilitates the disassembly of the chain housing and simplifies cleaning and routine maintenance. |
 |
Filter cover with two lateral elastic fastenings, removable without tools for easy inspection. Large nylon filter and air pre-filtering system with labyrinth to protect the machine in very dusty environments. |
 |
Automatic chain lubrication pump. When the motor is at minimum it does not supply oil, in order to reduce sawdust clogging and, consequently, cleaning and maintenance time. |
 |
Chain guard with large discharge section: facilitates sawdust ejection and reduces sawdust accumulation, reducing the time and frequency of cleaning and maintenance. Two protections, rubber on the chain casing and plastic on the tank, increase resistance in case of chain fall. |
