The safe use of metal balers is recommended to ensure that metal balers are used for a long time without failure. Use power and air sources that meet the requirements of metal balers. The second half of the metal baler (close to the control button) is equipped with electrical control components, no matter what the circumstances do not wash the body directly with water, otherwise there will be a risk of electric shock, damage to the electrical control components. In order to prevent electric shock, the machine should be well grounded, please equip a ground power socket for the metal baler. Be sure to turn off the air and power supply before removing and washing the metal baler. After the power switch is turned off, some circuits in the electrical control of the metal baler still have voltage, and the power cord must be unplugged during the maintenance of the control line.
