3 phase motors

I’ve got two questions regarding maintenance on motors. The first one is is there any hazards lubricating a motor in service I know obviously there will be mechanical safety to be aware of but electrical is there any issues. 


my second question is with motor overloads how bad for the motor is having a 1.8amp 10a overload on a motor with 1.75FLC I know it can still be overloaded by 50ma but is it a concern. 


thanks again guys!

    Such a small difference should do no harm. The motor may take many times F.L.C. at start up or under heavy loads for short periods.
