Swing motors and bearings in the swing drive are being severely damaged as a result of improper operation. Damage to these components occurs when the stick is pushed against the ground and the machine is turned. This forces the machine to rotate without oil flow to the swing motor and without disengagement of the swing brake. Excessive loads on the bearings of the swing drive and lack of proper lubrication of the swing motor will cause these components to fail.

Do not allow the machine to swing from the force of traveling when you use the bucket, the stick, or the boom to assist in travel. If the force from traveling causes the machine to swing, damage may occur to the swing motor and to the swing drive. |
Generally, the travel function of the machine should not be engaged while the weight of the machine is supported by the front linkage. Refer to Operation and Maintenance Manual, "Operating Technique Information" and Operation and Maintenance Manual, "Travel in Water and Mud" for exceptions to this guideline.
