Attention should be paid to the purchase of power tools: First, the power tool is a hand-held or portable mechanized tool powered by a motor or an electromagnet, which is driven by a drive mechanism to drive a work head. The power tool has the characteristics of convenient carrying, simple operation, and diverse functions, which can greatly reduce labor intensity, improve work efficiency, and realize manual operation mechanization. Therefore, the power tool is widely used in construction, housing decoration, automobiles, machinery, electric power, bridges, horticulture and other fields. , And a lot of home.
Power tools are characterized by their light weight, small size, light weight, low vibration, low noise, flexible operation, easy control and operation, easy to carry and use, strong and durable. Compared with manual tools, labor productivity can be increased several to tens of times; it is more efficient than pneumatic tools, lower cost and easier to control.
Please pay attention to the following points when purchasing electric tools:
1, according to the need to distinguish between family or professional use, most of the power tools are designed for professionals, in the purchase should distinguish between professional and general family tools. Usually the difference between professional and general family tools is in power, and professional tools are used in large power to facilitate professionals to reduce workload. The tools for general households are relatively small due to small projects, so the input of tools is relatively small. Power does not need to be great either.
2. The outer package of the tool should be clear in pattern, not damaged, and the plastic box should be firm. The buckle that opens the plastic box should be firm and durable.
3, the appearance of the tool should be uniform color, the plastic parts of the surface of the clear and dent marks, should not have scratches or bump marks, the assembly between the shell parts dislocation ≤ 0.5mm, aluminum castings smooth and beautiful without defects, the whole The surface should be free of oil stains and stains. When holding by hand, the handle of the switch should be flat. The length of the cable should generally not be less than 2 meters.
4, the tool's nameplate parameters should be consistent with the CCC certificate. The specification should have the full address and contact information of the manufacturer and the manufacturer. The nameplate or certificate shall have a lot number traceable to the product.
5. Hold the tool by hand, turn on the power, frequently operate the switch, make the tool start frequently, and observe whether the switch function of the tool switch is reliable. At the same time, observe whether there is any abnormality in the TV or fluorescent lamps at the scene. To confirm that the tool is equipped with a valid radio interference suppressor.
6. The tool is powered on for one minute. When it is in operation, it should be held by hand. The hand should not notice any abnormal vibration. Observe the reversal spark. The reversal spark should not exceed 3/2 level, generally from the air inlet of the tool. Look inwards, there should be no obvious arc on the surface of the commutator. When running, there should be no abnormal noise.
