。 。 。 The shell, the handle for cracks and damage; Whether the power cord, power plug is in good condition. 。 。 。 Electrical protection device and mechanical protection devices are in good condition; Protect the line connection is correct, solid and reliable. 。 。 。 Whether the rotor flexible rotation; The power switch movement is normal, flexible, and presence of defects. 。 。 Connect the electric circuits of the electric machinery and tools should be separately set the switch or socket, and furnish the leakage protector, leakage protector shall ensure that action is valid, it is forbidden to brake by multiple devices. 。 。 The operation of the electric equipment switch should be placed in the reach of the operator, when rest, work, or a sudden power failure should be promptly cut off the power switch. 。 。 In the general workplaces, should as far as possible to use Ⅱ tools (see appendix), using Ⅰ, Ⅱ tools (see appendix) leakage protector should be taken to protect; In wet workplaces or metal hook rack conductive properties such as good work sites, should use class Ⅱ or Ⅲ tools (see appendix). In the work place such as boiler, metal containers, the pipe, you should use Ⅲ tools, or furnish the leakage protector Ⅱ tools. 。 。 When using power tools must be correct to wear the necessary labor protection articles, mobile tools do not carry live parts or tools rotation. 。 。 Motion zero risk of tools, parts shall not be arbitrarily remove the protective device. 。 。 When using electric wrench, the torque should be protection by prison and confirm button nut rear can start. 。 。 When using electric magnetic sucker disk plane should level off, clean, no rust, sidetrack drilling or drilling time, after should be taken to prevent loss of electric drill fall prevention measures. When using electric tools, in order to reduce the fire, electric shock, and injury accidents, should check the following items:, a hood and a handle for cracks and damage; Whether the power cord, power plug is in good condition. , electric protection device and mechanical protection device are in good condition; Protect the line connection is correct, solid and reliable. And rotational part whether flexible rotation; The power switch movement is normal, flexible, and presence of defects. , connect the electric circuits of the electric machinery and tools should be separately set the switch or socket, and furnish the leakage protector, leakage protector shall ensure that action is valid, it is forbidden to brake by multiple devices. , the operation of the electric machine switch should be placed in the reach of the operator site, when rest, work, or a sudden power failure should be promptly cut off the power switch. Should be use as soon as possible, in the general workplaces, Ⅱ tools, should be taken when using tools, such as Ⅰ Ⅱ leakage protector protection; In wet workplaces or metal hook rack conductive properties such as good work sites, should use class Ⅱ or Ⅲ tools; In the work place such as boiler, metal containers, the pipe, you should use Ⅲ tools, or furnish the leakage protector Ⅱ tools. , using electric tools must be correct when wearing the necessary labor protection articles, mobile tools do not carry live parts or tools rotation. , tool dangerous sport of zero, parts shall not be arbitrarily remove the protective device. , using electric wrench, the torque protection should be buckled by prison and confirm the nut rear can start. , using electric magnetic sucker disk plane should level off, clean, no rust, sidetrack drilling or drilling time, should be taken to prevent loss of electric drill after fall prevention measures.
