CHECKING AND REPLACING THE CARBON BRUSHES
In order to keep the tool running correctly, you need to check the carbon brushes after
every one hundred hours of use. Carbon brushes wear out over time based on the
grinder’s usage. If a carbon brush is worn out, it may cause the motor to malfunction or
fail to run. The carbon brushes should be replaced before the twisted wire reaches the
bottom of the slot.
DANGER!
Be sure to unplug the power cord from the outlet before servicing the unit, to prevent
electrical shock or starting the tool accidentally.
REAR COVER REMOVAL
1. Remove the rear case screws.
2. Hold grinder with one hand and pull the
rear case straight back with the other
hand.
NOTE: Do not twist case in a side-to-side
motion when pulling back.
2 Pull back the rear case until the carbon
brush assembly is exposed.
