GB/T 3883.201-2017Safety of motor-operated hand-held,transportable and garden tools—Part 2: Particular requirements for drills and impact drills (English PDF)

3.101 drill

tool equipped with either a typical three jaw chuck or a machine taper, specifically designed to bore holes in various materials such as metal, plastics, wood, etc.

3.102 impact drill

tool equipped with a chuck specifically designed to bore holes in lightweight concrete, brick and other materials, being similar in appearance and construction, to a drill, but which has a built-in percussion system which gives an axial percussion movement to rotating output spindle

Some impact drills have a device for rendering the percussion system inoperative, so that they can be used as a conventional drill.

3.103 diamond core drill

drill designed to be equipped with a diamond core drill bit with or without a liquid system to drill into materials such as concrete or brick

3.104 mixer

a kind of electric tool mixing the coating, putty, mixed marl and similar materials

5.17

Addition:

The mass of the tool includes the drill chuck and the auxiliary handle, if any.

8.1

Addition:

——rated no-load speed, r/min or min-1.

8.3

Addition:

Drills, impact drills and diamond core drills shall be marked with the following:

——maximum capacity of the chuck, mm.

8.14.1

Addition:

The additional safety instructions as specified in 8.14.1.101 shall be given. This part may be printed separately from the “General Power Tool Safety Warnings”.

8.14.1.101 Addition

Drill safety warnings

——Wear ear protectors when impact drilling. Exposure to noise can cause hearing loss.

Note 1: the above warning applies only to impact drills and is omitted for drills.

——Use the auxiliary handle(s). Loss of control can cause personal injury.

Note 2: the above warning applies only to tools that are provided with auxiliary handle(s).

——Brace the tool properly before use. This tool produces a high output torque and without properly bracing the tool during operation, loss of control may occur resulting in personal injury.

Note 3: the above warning applies only for tools with a maximum output torque greater than 100N.m measured in accordance with 19.101.

——Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock.

——Do not turn the mixer on or off unless it is located in mixed materials. Failing to do so may result in personal injury.

8.14.2a) Addition:

101) for diamond core drills: maximum diamond core bit diameter, mm;

102) for tools with a average output torque greater than 100N.m measured in accordance with 19.101: instructions on how to brace the tool;

103) for mixers, applicable mixing medium for mixing device shall be specified.
