There are few important points which we must consider when going to inspect the used Excavators.
Check for Play/Movement

Check all the connection points, particularly between stick, boom, and bucket and see the movement of these parts.
Check the cylinders, hoses, and lines to ensure there is no leakages in hydraulic cylinders, Leaks in the cylinders indicate the misuse of the machine by the owners. The buyer should open the hydraulic pump compartment and check for any types of leaks. If there any leaks found, make sure the owner of the machine repair it before handing over to you for safe and smooth operation.

Check Hour Meter
Every machine has a limited working life span, so do for excavator, so always prefer the excavator which used for lesser hours. Therefore, it is suggested to check the hour meter to ensure a correct number of hours is logged on the machine. In case, meter hour is not working, then check the control pedals for wear. The high amount of wear on the pedals indicates hydraulic excavator has extra operating hours logged than noted.
