Question : What can I due to maintain my ECG-125/225 and keep it running like new?
Answer : Unplug the tool, remove the grinding wheel and belt covers to check and clean the belts after every 100 hours of use. Concrete dust may get inside the covers and onto the belts and pulleys, this can cause the belts to wear and the pulleys to slip. The belts should be replaced when showing signs of wear. A worn or stretched belt will not be able to center itself on the pulleys and can come off or wear a hole in the belt cover. After every 300 hours of use you should check the carbon brushes. Replacement of the belts and carbon brushes on a periodic basis is the first step to any type of maintenance. If complications begin to arise during the grinding application, or if unusual noises occur, check the belts and pulleys. If the unit is working correctly and you still hear the noise, this could be an indication that a bearing is worn. If this occurs, then we recommend that you send your tool in for repair.
