A series of inspections and tests should be carried out after repairing the electrical parts of power tools to ensure their safety and performance. The following are the specific steps and points:

First, insulation test

The first thing to be carried out after the repair of electrical tools is insulation testing. The use of professional insulation test instruments, such as megohmmeter, the tool for insulation resistance measurement. This will ensure that the electrical components inside the tool will not come into contact with other metal parts and lead to a short circuit or risk of electric shock.

II. Function check

Functionality checks are done to confirm that the power tool will work properly after repair. This includes checking the operating status of the motor, the charging and discharging of the batteries, and the responsiveness of the switches. The function check ensures that the tool will work as expected after repair.

III. Safety Performance Test

Safety performance testing is an important part of assessing whether a power tool can maintain safe operation under specific conditions. This includes overload protection test, short-circuit protection test, and so on. By simulating the abnormal situation in the actual work scene, it can ensure that the tool can cut off the power supply in time to avoid accidents under abnormal conditions.

Fourth, appearance check

In addition to the inspection of the electrical part, the appearance inspection is also essential. Check whether the shell of the tool is damaged, whether the wire is worn or broken, etc.. These cosmetic defects may lead to safety hazards in the use of the tool.

Fifth, operation test

The operation test is to verify the performance of the power tool in actual operation. Allow experienced operators to use the repaired tool for actual operation, to observe the tool's performance and operating feelings. This will provide a more intuitive understanding of the tool's performance in actual use.

Sixth, records and reports

All inspections and tests should be recorded in detail and reports generated. The report should include details of the inspection, the results of the test and any problems found and recommendations. This will provide an important reference for subsequent maintenance and repair.

In summary, the electrical parts of power tools should be insulated, functionally checked, safety performance tested, appearance checked and operationally tested after repair. All these checks and tests are to ensure that the power tools can work safely and reliably after repair, and bring users a better experience.
