How to operate?
A: The driver should concentrate on thinking, one person operation, one person monitoring, always pay attention to whether the reading of the meter hand (current and voltage oil pressure) is normal, and pay attention to the parking position recorded on the depth indicator and roller. After the motor is started, the winch speed reaches a certain level. When the rated value is reached, the working brake handle will be pushed to the head and the force shall not be used too hard. After the vehicle is parked, the controller must be placed in the power off position and the brake must be braked.
