When using an electric chain saw for cutting, ensuring the flatness and verticality of the cut surface requires many considerations and operating skills.
First, holding the electric chain saw correctly is the basis. The operator should hold the handle of the electric chain saw tightly with both hands, keep the body stable and balanced, and stretch the arms naturally to avoid the electric chain saw deviating from the predetermined cutting line due to body shaking or arm trembling during the cutting process, thereby affecting the flatness and verticality of the cut surface. For example, when cutting larger wood, you can stand with your feet shoulder-width apart to enhance the stability of your body.
Secondly, the precise starting cutting position is crucial. After determining the cutting line on the wood, align the chain of the electric chain saw with the starting point of the cutting line, slowly start the electric chain saw and gently cut into the wood. At the beginning, make sure that the chain is perpendicular to the wood surface. If there is a deviation, the deviation will gradually increase during the subsequent cutting process. You can use tools such as a square to mark the accurate vertical starting point on the wood surface to lay the foundation for subsequent flat and vertical cutting.
In addition, a uniform and stable propulsion speed is the key. During the cutting process, the electric chain saw should maintain a uniform forward speed, not too fast or too slow. If the advancement speed is too fast, the chain may jump due to uneven force, resulting in an uneven cutting surface; if the speed is too slow, it may cause wood burns or rough cutting surfaces. Operators need to master the appropriate advancement speed through repeated practice according to factors such as the hardness of the wood and the power of the electric chain saw, and ensure that the chain moves smoothly along the cutting line to obtain a smooth cutting surface.
In addition, it is essential to keep the electric chain saw chain sharp. A sharp chain can cut into the wood more smoothly and reduce cutting deviations caused by jamming. Regularly sharpening the chain or replacing severely worn chains in time can make the cutting process more stable and efficient, which is conducive to improving the quality of the cutting surface.
The maintenance and adjustment of the guide bar also affects the cutting effect. Make sure that the guide bar is installed correctly and flat, without bending or deformation. If there is a problem with the guide bar, the chain running track will be unstable, which will affect the cutting surface. Before each use, check the flatness of the guide bar and adjust or replace it as needed.
At the same time, for longer or larger wood, the support points can be appropriately increased during the cutting process. Prevent the wood from bending and deforming due to its own weight or cutting force, which affects the verticality of the cutting. Auxiliary supports or workbenches can be used to keep the wood in a stable state during cutting.
Finally, the operator's experience and skill accumulation are also important factors in ensuring the flatness and verticality of the cut surface. Through continuous practical operation, familiarity with the performance characteristics of the electric chain saw, and mastering the operating skills under different wood and cutting scenarios, we can better cope with various situations during the cutting process and obtain high-quality cut surfaces.
