The electric circular saw is a tool that uses a single-phase series-excited motor as the power to drive the circular saw blade through the transmission mechanism for sawing. It has the characteristics of safety, reliability, reasonable structure and high efficiency. It is easy and common to flip the electric circular saw upside down, but it is also dangerous, so you must pay attention to the operation method when flipping to avoid the danger. So how to operate the electric circular saw flip?

  Electric circular saw flip method
Â
First of all, the flip saw must have a solid table. After aligning the vertical and horizontal directions, the electric circular saw should be placed on the table with its own bottom plate, and the saw should be slowly dropped upwards and downwards to make a saw blade. Exposed, the bottom plate is completely in contact with the table. This saw cut must be parallel to the edge of the tabletop in the horizontal direction and perpendicular to the tabletop in the vertical direction. This is an important indicator to determine the accuracy of your sawhead. Then fix the saw to the tabletop with screws and turn the tabletop over so that the saw It is flipped upside down. If the saw is large, it should be supported underneath to prevent the saw from shaking during operation. Finally, install the backer, pay attention to the backer must be accurate, strong and firm, if possible, install the dividing knife and protective cover even if it is completed.

Structural characteristics of electric circular saw
Â
The electric circular saw adopts a climbing structure, which is mainly composed of a motor, a reduction box, a protective cover, an adjustment mechanism and a bottom plate, a handle, a switch, a non-reconnectable plug, and a circular saw blade. The motor uses a single-phase series-excited motor. It is divided into a single-insulated electric circular saw (no additional insulation between the stator and the ground, also known as type I tool) and a double-insulated electric circular saw according to whether there is additional insulation between the stator and rotor cores and the ground. (There is additional insulation between the stator and rotor and the ground, also known as type II tool).
The adjustment mechanism is composed of a depth adjustment plate, an angle adjustment plate, a fastening nut and a bottom plate, etc. Loosen the fastening nut to adjust the bottom plate up and down to the required cutting depth, and then tighten the nut. The angle adjustment is by loosening the oblique angle adjustment screw butterfly nut in front of the base plate to the desired angle (0 ° ~ 45 °), and then tightening the nut.
The protective cover in the structure of the electric circular saw is composed of an electric protective cover (also called a lower protective cover) and a static protective cover (also called an upper protective cover) to protect the circular saw blade and prevent injury accidents during operation. The static shield is connected with the casing, the dynamic shield rotates along the circular saw blade, and automatically covers the saw blade by the pressure of the coil spring. The power cord of the electric circular saw uses a double-core sheathed flexible cable, which is integral with the double-post rubber plug to form a non-reconnectable plug.
The above is the introduction of the electric circular saw flip method and the structural characteristics of the electric circular saw. In fact, the electric circular saw is also a very common tool and equipment in our lives. It will be used in industries that require cutting operations. Therefore, it is very necessary to understand its related knowledge. In particular, you should be familiar with the correct flip method of the electric circular saw to avoid some dangers.
