Chain tensioning system
The chain tensioning system is used with the special key included in the chainsaw set. The chain is stretched by changing the distance between the driven and driving sprockets, which allows you to reliably fix the tire with the necessary tension. The advantage of this system is a more reliable fixation of the tire, and also for longer work the chain is less susceptible to weakening.
Bus and chain
It is equipped with an electric jigsaw with a 406mm bus. It is a flat metal structure along which the cutting chain moves. The length of the bus is measured in millimeters or inches. Also the size of the bus affects what kind of trunk the operator can cut in one step. When choosing a spare bus and chain, take into account the chain pitch and groove size under it. To ensure the rated load, it is recommended to install a bus with a length of no more than 16 inches.
A full-size nylon mesh air filter is installed. This filter provides an increased flow of purified air, reducing the likelihood of clogging the carburetor. Due to increased capacity, the load on the carburetor is reduced. Quick access to the air filter and carburetor facilitates the maintenance of the fuel system. The fuel filter is cleaned with the ceramic fuel filter installed. It provides high cleaning, thereby preventing premature wear and clogging of the fuel system.
The adjustment of the carburetor is an important element of the functionality of the chainsaw. The carburetor undergoes quality control; optimum dynamic performance is achieved with optimum fuel consumption. Precision milling of parts ensures reliable operation of the carburetor. To increase the service life of the carburetor, it is recommended to use a suitable fuel mixture.
The chrome plated coating of the cylinder walls provides increased durability when the cylinder-piston group is operating. There are 2 compression rings, which ensure reliable prevention of gusts from the combustion chamber. Quality casting and milling allows for the most accurate positioning of components with minimal gaps. Only qualitative gaskets with a protective hermetic coating are installed.
