Specification for use of hand-held electric tools

pistol electric drill:

unsafe factors (dangerous points)

I. electric shock:

the utilization ratio of degradable green packaging materials will reach 50% in 2020. 1. The use of power supply voltage must be consistent with the voltage specified by the tool

2. Before use, it is necessary to check that the interior, shell and wire are well insulated, and there is no leakage

3. there must be a correct grounding device before use, and the plug cannot be inserted in the wrong position

4. Before use, according to the different types of tools used, install qualified leakage protectors with rated action current of no more than 15 mA, action time of no more than 0.1 seconds or rated leakage action current of no more than 30 Ma, which make our contribution to providing the most stable and reliable high-performance optical fiber network and action time of no more than 0.1 seconds

5. When working in metal containers, a special person must be assigned to continuously monitor outside. Leakage protectors, power connectors and control boxes should be placed outside the containers. Insulating plates should be placed under the feet of workers. When using electric tools in particularly wet places, appropriate work clothes, insulating gloves and insulating shoes must be worn

II. Mechanical injury:

1. Before use, it must be confirmed that the electric drill is qualified, with labels or certificates

2 by using the electronic tension machine, it is necessary to check that the nuts of the mechanical transmission part are fastened firmly before use, and it can be used only after it is qualified

3. Before connecting the power supply, carefully check that the switch of the tool used should be in the off position before connecting the power supply

4. when replacing the drill bit, the power plug must be unplugged before replacement. Check that the drill bit has no cracks and surface defects, and then install it after it is qualified

5. when using, the workpiece must be reliably fixed on the workbench, and the drill bit must also be clamped. The drill bit must not collide with the machine body and workpiece

6. when working, do not contact the drill bit with objects with force, but gently contact the appropriate entry, and keep your hands away from rotating parts

7. wear protective glasses and appropriate work clothes when working. People with long hair must wear hats. The working place must be cleaned. There must be nothing twisted by the drill. Both hands must hold the tools tightly and be extra careful

8. When working, the body must maintain a proper and correct posture, and must stand firmly. Do not reach over the tools to take things and process work

9. after turning off the switch, the tool used must be put in a safe and reliable position after the machine is completely stopped, and then unplug it

10. It is strictly forbidden to handle the workpiece with one hand and work with a pistol electric drill with the other hand

11. There must be more than 2 people at work, and there must be a special person for continuous monitoring

electric wrench:

unsafe factors (dangerous points)

I. electric shock:

1. The use of power supply voltage must be consistent with the voltage specified by the electric wrench

2. Before use, it must be checked that the interior, shell and conductor have good insulation, and there is no leakage

3. there must be a correct grounding device before use, and the plug cannot be inserted in the wrong position

4. Before use, install qualified leakage protectors with rated action current of not more than 15 mA and action time of not more than 0.1s or rated leakage action current of not more than 30 Ma and action time of not more than 0.1s according to the different types of tools used

5. When working in metal containers, a special person must be assigned to continuously monitor outside. Leakage protectors, power connectors and control boxes should be placed outside the containers. Insulating plates should be placed under the feet of workers. When using electric tools in particularly wet places, appropriate work clothes, insulating gloves and insulating shoes must be worn

II. Mechanical injury:

1. The wrench must be confirmed to be qualified before use, with labels or certificates

2. Before use, the nuts of the mechanical transmission part must be checked for tightness, and can be used only after they are qualified

3. when replacing the wrench, the power plug must be unplugged before replacement

4. when using, the wrench must be reliably fixed, and both hands must be firmly held (under special circumstances, the wrench can be lifted and fixed), so as to prevent the danger of tools moving without permission

5. Before starting the machine, the rotation direction must be determined, and the work can be carried out only after it is confirmed that there is no abnormality. The force should be even during the work, and excessive force is not allowed

6. More than 2 people must be assigned to operate the operation box and control the operation and stop of the electric wrench

7. when using, the wrench should be righted to avoid touching the wrench head and strictly prevent the cable from falling off with electricity

8. when working, the body must maintain a proper and correct posture, and must stand firmly to align and hold the tool axis with the thread axis

9. before connecting the power supply, carefully check that the switch of the tool used should be in the off position before connecting the power supply

10. after turning off the switch, the tool used must be put in a safe and reliable position after the machine is completely stopped, and then unplug it

11. when working vertically, more than two people must hold the tool and a third person must operate it

12. more than 2 people must be assigned to carry out continuous monitoring during work
