Before the test, a thorough inspection is required. Check the oil level on the gear unit and clean it. After confirming the error, you can send the power to test the vehicle. After no problem, remove the wood from the support slip, and then carry out the load test, and the rear can be closed.

7. The following provisions shall be imposed for the power transmission:

1. The person in charge of power transmission will power off and lock the switch, and will be sent to the special person for care (stopping the operator).
