The manual is the same for all of them as they probably just copy each other. As lon as you have the motor speeds and steps per unit right the machine will work. The difficult thing would then be to learn how to use Mach3 or EMC and then how to make gcode.

In the meantime try not to over stress the spindle as it tends to pop a diode on the speed control board and of course the stepper control board is not the most reliable.
