Possible dangers when using branded power tools
Electric wrench:
Unsafe factor ( dangerous point )
First, electric shock:
1. The power supply voltage must match the voltage specified by the electric wrench.
2. The inner, outer casing and wire must be inspected for good insulation before use. No leakage is allowed.
3. The correct grounding device must be used before use, and the plug cannot be inserted in the wrong position.
4. Before use, install a qualified leakage protector with a rated operating current of no more than 15 mA, an operating time of no more than 0.1 sec, or a rated leakage current of no more than 30 mA and an operating time of not more than 0.1 sec.
5. When working in a metal container, special personnel must be provided for continuous monitoring. The leakage protector, power connector and control box should be placed outside the container. The insulation board should be placed under the staff's feet. Use power tools in particularly humid places. Appropriate overalls, insulated gloves and insulated shoes must be worn.
Second, the mechanical damage caused by brand power tools :

5. Before starting the machine, you must determine the direction of rotation, and then confirm that there is no abnormality before working. The working force should be even, and the force is too strong.
6. There must be more than 2 people working, and the special person operates the operation box to control the work and stop of the electric wrench.
7. When using the wrench, you should avoid the wrench and avoid the cable from falling off.
8. The body must maintain proper posture when working, and must stand firm so that the tool axis is aligned with the thread axis and is stable.
9. Before turning on the power, you must carefully check that the switch of the tool you are using should be in the off position before you can turn on the power.
10. The tool used must be placed in a safe and secure position after the switch has been completely stopped, and then the plug is unplugged.
