Gasoline engine, transmission by saw general agency, saw wood mechanism etc. Homework, power through the traditional institution, that saw saw chain drive along the chain to a continuous movement for gib sawing wood.

Engine: general for single cylinder two stroke air cooling the gasoline engine. In order to adapt to the fire-fighting sawing direction in different position, the different work with oil pumps pumps membrane type carburetor, use in the crankcase pressure pulsation of driver diaphragm pumps oil, making the engine in any position can normal oil supply. In addition, increasingly widespread adoption of transistor non-contact magneto ignition system and check air intake system and so on the new structure, so as to increase the engine performance.

Transmission mechanism: including the clutch and the centrifugal friction reducer. Reducer general use of the cone this round of reducer, easy to make wood sawing institutions in the relative for horizontal and vertical adjustment, in order to adapt to the logging and made different material sawing direction needs.

Wood sawing institutions: is the working parts of the fire-fighting, including driver sprocket, saw chain, transit, chain saws tensioning devices and put wood tooth, etc.

For gasoline, saw the future development trends of the will is made of new materials, new technology, and new structure, to further reduce the fire-fighting weight; Reducing noise and vibration, reduce air pollution, to improve the operating conditions; Add safety protection devices, in order to improve the reliability and safety use, and will continue to improve the power of the engine to the rotor new fire-fighting and remote control fire-fighting.
