Please charge the Model A by following the steps below: 

 

Ensure the Model A is safely parked indoors in a well-ventilated room and has both its brakes 
engaged. 

 

Turn off the power. 

 

Connect the AC cable to the battery charger’s AC receptacle. 

 

Connect the round DC plug to the charger port above the right motor brake knob on the 
Model A (seen in Figure 1). 

 

Connect the AC cable directly into a wall outlet with proper grounding earth. 

 

The charging status indicator should go from red to orange. When it becomes a steady green 
light, charging is complete. Unplug the DC plug and AC cables. 

 

Depending on the battery’s condition, it may take 8 - 9 hours to fully charge.  
 
Note:  

 

If the status indicator is blinking red, it is in safe mode. To reset, unplug the charger from the 
wall outlet for 5 seconds and re-plug it. 

 

 If the Model A is turned on during charging, you will see an error code and will not be able 
to operate the Model A.  In this case, turn off the Model A and unplug the charger before 
turning on the power.
