Question: Brushes Sparking

robert

I got this used 110 electric jack hammer, using the jack hammer side. It was working pretty good till it started smoking.

Reply: Brushes Sparking

Hi Robert,

The smoke was probably coming from the motor. If the motor is overloaded or if too small of an extension cord is used it will create heat in the motor. When the motor heats up it begins to melt and burn the insulation on the armature and the field. Once enough of the insulation burns away the armature and field will short out. I repair shop can test both the armature and the field to determine if one or both of them are bad. The armature is part #360-426U and the field is part #340-381K. Both parts are available from http://www.ereplacementparts.com.

I hope this helps with your repair!
