![]() ![]() Today’s business owners understand that maintenance is one of the key components of minimizing TCO, and getting the most efficiency and reliability out of their fleets. Operating an excavator with worn out teeth on the bucket essentially causes the machine to work against itself, reducing productivity, consuming more fuel, more man-hours and eventually leading to more downtime. Operators should also regularly inspect the thumb and bucket teeth for wear. Also, check the operator’s manual for regular grease intervals for the pins/bushings/coupler-keeping these components properly lubricated will extend the life of the attachment. In order to prevent unnecessary wear, areas around the pins and bushings should be cleared of dirt and debris. The small size and simple design makes the device easy to use and service. Operators should make the bucket and thumb a part of their everyday walkaround machine inspection.
