Tips on Tension
Trenching attachment maintenance is the key to not only extending the life of the tool, but also is critical in boosting performance. What should your daily checklist include?
In addition to checking items such as hoses, teeth and lubrication, make sure you’re checking the digging chain tension, a maintenance need that’s often overlooked. If the tension is incorrect, components such as sprockets, idler bearings and the chain itself will suffer excessive wear. Although styles can vary, the typical maximum sag for the chain is about 1 1/2 inches. Put the trencher attachment in the horizontal position so that you can check the sag of the chain, and then correctly adjust the tension.
