The Operation and Maintenance Manuals for the above machines now include a procedure for the proper daily maintenance of the cylinders. The procedure recommends that debris and mud should be removed from the stabilizer cylinders and the swing cylinders in order to prevent mud and debris from accumulating.
The accumulation of mud and debris may cause damage to the cylinders. Cylinder damage can include hydraulic oil leaks, cylinder drift, broken cylinder rods and bends in the cylinder rod. This procedure will improve the service life of the cylinders. The procedure is located in the "Daily Inspection" section of the manual.
Also, the Operation and Maintenance Manuals now have a note regarding the possibility that the backhoe bucket may come into contact with the stabilizer cylinders if the stabilizers are not fully raised. This situation could cause damage to the cylinders. The note is located in the "Stabilizer Control" section of the manual.
The following graphics show the areas of the machine that the accumulation of mud and debris can occur.
