Introduction

In.2014, my country issued the national standard GB/T 3883.1-2014 ``Safety No. of Handheld and Portable Power Tools and Garden Tools''

Part 1.General Requirements, the original GB/T 3883 (part of hand-held power tools), GB/T 13960 (part of portable power tools) and

The common technical requirements of the general safety standards for the three major series of electric tools in GB/T 4706 (only for garden power tools) have been integrated.

There are 3 parts in the special requirements for specific types of small products that are used in conjunction with GB/T 3883.1-2014.

Portable power tools part), part 3 (portable power tools part), and part 4 (garden power tools part), all transform the corresponding country

The specific requirements of the international standard IEC 62841 series.

The main element of the standard name is expanded to "safety of hand-held, portable power tools and garden tools", and the original hand-held power tools are used

Part of the standard number GB/T 3883.The standard sub-part number of each sub-category product consists of three digits, of which the first digit

Indicates the corresponding part, the 2nd and 3rd digits indicate different subcategories.

The new version of the GB/T 3883 series of standards will form a more scientific, complete, universal, and unified series of safety standards for electric tool products

The system makes the implementation of the standard more practical and convenient to use.

At present, the new version of GB/T 3883 series standard "portable electric tools part" has published standards as follows.

3.101

Anti-kickback device

A device that allows the workpiece to move in the sawing direction while reducing the possibility of the workpiece moving quickly in the direction opposite to the feed.

3.102

Bevelangle

The angle at which the plane of the saw blade is inclined to the table surface. The position of the saw blade plane perpendicular to the table surface is regarded as the 0° tilt angle position.

3.103

Crosscutting

A sawing operation in which a cross saw is used to guide the workpiece by the fence.

Note. For natural wood, the cross saw is mainly used in the direction perpendicular to the wood grain; for engineering materials, the cross saw is used in the direction perpendicular to the length of the workpiece.

3.104

Cuttingcapacity

When the saw blade is set at any cutting depth at the position of an inclination angle of 0°, the height of the highest tooth tip of the saw blade above the table.
