VIDO produces professional tools and small machines, and exports its products overseas. The article introduces the structural characteristics of DC circular saws.

The DC circular saw is a tool that uses a single-phase series motor as the power and then drives the circular saw blade through a transmission mechanism to perform sawing operations. It has the characteristics of safety, reliability, and high work efficiency.

Introduction of DC circular saw:
The DC Circular Saw is a tool that uses a single-phase series motor as the power to drive the circular saw blade through a transmission mechanism to perform sawing operations. It has the characteristics of safety, reliability, reasonable structure, and high work efficiency. It is suitable for sawing operations on wood, fiberboard, plastic and flexible cables and similar materials. The DC Circular Saw adopts a climbing shape structure, which is mainly composed of a motor, a reduction box, a protective cover, an adjustment mechanism and a base plate, a handle, a switch, a non-reconnectable plug, and a circular saw blade.

Structural characteristics of DC circular saw:
The DC Circular Saw adopts a climbing shape structure, which is mainly composed of a motor, a reduction box, a protective cover, an adjustment mechanism and a base plate, a handle, a switch, a non-reconnectable plug, and a circular saw blade. The motor adopts a single-phase series-excited motor. According to whether there is additional insulation between the stator and rotor cores and the ground, it is divided into a single-insulationDC Circular Saw (no additional insulation between the stator and the ground, also known as class I tools) and a double-insulated DC Circular Saw (Additional insulation is provided between the stator, the rotor and the ground, also known as class II tools). The adjustment mechanism is composed of a depth adjustment plate, an angle adjustment plate, a fastening nut, and a bottom plate. Loosen the fastening nut to adjust the bottom plate up and down to the required cutting depth, and then tighten the nut. Angle adjustment is by loosening the angle adjustment screw wing nut on the front of the bottom plate, adjusting to the required angle (0°～45°), and then tightening the nut.

The main attributes of DC circular saws:
1. Rated power;
2. Cutting ability;
3. Diameter of cutting blade (length of saw blade);
4. No-load speed.

Protective cover of DC circular saw:
1. The protective cover 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 guard is connected with the casing, and the movable guard rotates along the circular saw blade and automatically covers the saw blade by the pressure of the coil spring.
2. The power cord adopts a double-core sheathed flexible cable, which is integrated with the double-post rubber plug to form a non-reconnectable plug.
The purpose of DC circular saw:
Circular saw blade is the working tool ofDC Circular Saw. There are two kinds of longitudinal cutting type and cross-cutting type. A qualified circular saw blade with standard diameter should be used. Saw blades made of high-speed steel and deformed or cracked saw blades must not be used.

Precautions for DC circular saws:
1. The circular saw blade is not installed correctly. After the saw teeth become blunt due to a large force, the wood will be thrown and injured during sawing.
2. The circular saw blade has defects such as cracks, unevenness, and skew. The broken saw blade makes the circular saw blade hit during work, causing the wood to throw or the circular saw itself breaks and hurts people.

3. Safety protection defects, such as transmission belt protection defects, damaged hand guard safety devices, unprotected zero connection, leakage protection or failure of its devices, etc., causing safety accidents.

Features of DC circular saw：
1. The powerful motor meets heavy and difficult projects.
2. The cutting depth is adjustable. The variable cutting depth can be applied to different tasks.
3. Ergonomic handle. More comfortable holding experience, reducing work fatigue.
4. Different auxiliary handle positions make work more convenient
5. 4000mAh large-capacity battery, super long running time.
6. Dust collection design. The machine has a longer life and a cleaner working environment.
