FAQ

The voltage must be confirmed before input power. Keep the Electric Screwdriver clean and from water. Replace the carbon brush regularly. Remove the carbon powder when replacing the carbon brush lest it accumulates and results in short-circuit. The carbon brush should be replaced when only 1/4 remains. Use the original manufactures carbon brush. If harder carbon brushes are use, they may last longer but will cause abnormal wear of armature. It is not worth it. Motor bearing should be oiled regularly. Add proper amount of oil only. Too much oil will flow into the inside of the magnet shell and cause the motor to overheat and lose magnetism and reduce the torque force. Gear boxed should be greased with grease specific for gears. Do not use liquid oil or butter. The stickiness of butter will cause the gear component to overheat. Do not drop anything into the equipment during the greasing process lest it damages the equipment. Do not use replacement parts for the parts to ensure the accuracy of the torque. For anything other than the situations listed above, please contact the providers of the screwdriver and let the technical staff handle it.

The torque control methods for automatic/semi-automatic When the automatic torque control (shut-off clutch) model reaches the pre-set torque value, the clutch will disengage and the motor will brake immediately. The screwdriver head will stop rotation and there is no reaction force. The accuracy will be within 3% and is suitable for the use in occasions that require high precision torque assembly. When the semi-automatic torque control (slip clutch) model reaches the pre-set torque value, the clutch will disengage and the screwdriver head will stop rotation immediately. However, the motor will stop rotation only after the release of the start switch. It is suitable for the use of occasions that do not require precision torque assembly and it has the advantages of low malfunction, easy maintenance, and low price.

Electric Screwdriver is an important tool on the assembly line. Only if suitable tools are used, is it possible to increase the work productivity. How do you purchase the suitable Electric Screwdrivers? The first thing to consider is the range of the torque and its accuracy for the screwdriver. Only if the range of the torque can cover the desired value (the maximum value of the torque value of the screwdriver must be larger than 1.1 times of the work value to ensure the lifetime of the screwdriver), can the screwdriver achieve the maximum work value. Secondly, the malfunction rate of the screwdriver, its lifetime, and the customer services of the provider and its ability to provide all kinds of answers to questions and inquiries are also options to be considered during purchasing.

All the work objects are designed for certain torque values. However, the dials on the Electric Screwdriver provide relative torque values for reference. Therefore, the precision calibration of the torque value is required to ensure the uniformity of the torque value of each screw on the work objects. Hence, the torque tester to provide uniform and accurate torque value is needed. The Electric Screwdriver needs the torque tester to calibrate the dials of the torque to provide the uniformity of the torque value.
