I would like to check that the blades are running all well. With the belt installed, (and the motor off ofcourse) I move them with the hand and seemed that:
* they seemed stuck or jammed, they move but I must do a little force (not much )
* I hear some funny noise (like metal vs metal) just beneath the motor
I would like to take the belt out and move each blade separately. I will do it next time.
How could I check that the motor is ok?
What should I do with the blades on switch? (is an electric button)
The electric clutch has a built in brake for the blades. if you remove the belt should be able to turn the blades free. That brake won't effect the operation of the motor.
