WARNING! If the supply cord of this power tool is damaged, it must be replaced only by a qualified service technician.
4.Carbon Brush Maintenance.
The carbon brushes may require maintenance when the motor performance of the tool decreases or stops working completely. To maintain the brushes:
a.Remove the Carbon Brush Cover on each side of the motor housing.
b.Remove the carbon brushes from the housing. Keep track of which orientation the old carbon brushes were in to prevent needless wear if they will be reinstalled.
c.If either carbon brush is worn down by more than 1/2, replace them both.
d.To clean old carbon brushes before reusing them, rub the contact areas with a pencil eraser.
e.Reinsert the old carbon brushes in the same orientation to reduce wear.
f.When installing, make sure the carbon portions of the brushes contact the motor armature, and that the springs face away from the motor. Also, make sure the springs operate freely.
g.Replace the Carbon Brush Covers. Do not overtighten.
Note: New carbon brushes tend to spark when first used until they wear and conform to the motor’s armature.
