4.3.2 Battery Charging Criteria The battery charge status can be checked on the inverter screen under the top cover of the mini digger. When the displayed voltage drops below 45V, it is recommended to commence battery charging. In cases where the stored energy in the batteries is not recharged, it will suffice for operation within a range of 20 to 40 minutes, depending on the load of the mini digger.
Page 18
Information: Automatic cooling systems do not operate in the 230V power grid charging mode. Therefore, the top cover of the machine should be open during charging to ensure proper air circulation and heat dissipation. Warning: During charging, the mini digger must be protected from snow, rain, and other factors that may cause excessive moisture.
Page 19
PIC. 4.7 Connecting to 230V power grid charging 4.5. Emergency stop and shutdown Warning: Emergency stopping and/or shutdown should be applied in every situation where the machine may cause harm to individuals or damage to nearby equipment. Warning: After an emergency stop and/or shutdown, do not restart the mini digger until the cause of the stoppage has been addressed, and ensure that the machine can operate safely.
Page 20
4.5.1 Emergency shutdown button The emergency shutdown button is located on the mini digger's steering panel. Pressing it results in an immediate cutoff of electrical circuit power, leading to the complete shutdown of the machine. This button shuts down: the inverter power supply from the external grid, the power supply, radio receiver, lighting, ventilation, frequency converter, and the engine.
Page 21
PIC.4.9 Restart after pressing the emergency stop button 4.5.5 Utilizing the Emergency Stop Button Function for Energy Saving The emergency stop button function can serve as a work pause when the mini digger is temporarily idle. This allows for energy conservation that would otherwise be consumed by the operation of the hydraulic drive engine system.
