Polishing the result comes to the conveyor coupling and shaft drive connection between the motor until it causes the power lock much torque causes the power lock torque bolt torque deficits before so will be cut.
Contrary to the conveyor, resulting in the coupling connecting the motor and the drive shaft torque power lock and cause so much torque that much power lock bolt torque before the cut.
The Polish conveyor result comes coupling connection between motor and drive shaft to cause the torque power lock so much that cause torque. Power lock until a bolt lack before torque to be cut.
