Precautions for using the test machine

Precautions for using the test machine
1) Before starting the machine, rotate the speed regulator counterclockwise to zero point to prevent impact torque from being generated during startup and damage the parts of the test machine.
2) After applying torque, it is prohibited to rotate the "range selection handwheel" and change the "speed switch".
3) The forward and reverse load buttons on the panel cannot be pressed at the same time. To change the applied torque direction and the changing speed switch, you must first press the "Stop" button before changing the torque direction and the changing speed switch.
4) The operator cannot leave when the test machine is running. If abnormal sounds or any other faults are found, the machine should be shut down immediately and reported to the instructor for processing.
