Alpha Tool.Com.HK Limited 225 Checking and Replacing the Carbon Brushes, Rear Cover Removal

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.
