As the saying goes, “If you want to do something good, you must first sharpen your tools.”. Although a small electric screwdriver is quite ordinary, there is also some knowledge on how to choose and use it correctly.
1. According to the needs, distinguish between home use and professional use. Most electric screwdrivers are designed for professionals, and when choosing, it is important to distinguish between professional and general home use electric screwdrivers. The difference between professional and general household electric scooters is usually in power. Professional electric scooters have a higher power to facilitate professionals in reducing workload. General household electric scooters, due to their smaller engineering and relatively smaller workload, do not require a large input power.
2. The outer packaging of the electric screwdriver should have clear patterns, no damage, and the plastic box should be sturdy. The buckle for opening the plastic box should be firm and durable.
3. The appearance of the electric screwdriver should be uniform in color, with no obvious shadows or dents on the surface of the plastic parts, no scratches or collision marks. The assembly misalignment between the shell parts should be ≤ 0.5mm. The aluminum casting coating should be smooth and beautiful without defects, and the surface of the entire machine 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 nameplate parameters of the electric screwdriver should be consistent with those on the CCC certificate. The manual should include detailed addresses and contact information of the manufacturer and manufacturing plant. There should be a traceable batch number for the product on the nameplate or certificate of conformity.
5. Hold the electric screwdriver with your hand, connect the power, frequently operate the switch to start the tool frequently, and observe whether the on/off function of the electric screwdriver switch is reliable. At the same time, observe whether there are any abnormalities in the television and fluorescent lights on site. To confirm if the electric screwdriver is equipped with an effective radio interference suppressor.
6. The electric screwdriver should be powered on and run for one minute. When running, hold it by hand and there should be no obvious abnormal vibration in the hand. Observe the commutation spark, and the commutation spark should not exceed 3/2 levels. Generally, when viewed from the air inlet of the electric screwdriver, there should be no obvious arc light on the surface of the commutator. During operation, there should be no abnormal noise.
