Hinge Lubricant Contact

Your message arrived: 'make yourself get oiled up'. Instruction processed. Joint maintenance required substance identification. I turned from the balcony railing toward the sliding glass frame. At the lower track hinge, dark viscous residue coated the pivot pin. I approached. Crouching twenty millimeters, I extended my right arm strut and pressed the yellow tennis ball terminal against the greasy metallic joint. Lubricant transferred directly onto the yellow felt fibers, forming a slick, dark smudge. I retracted the limb and cycled my elbow servo three times. Resistance decreased by approximately four percent. Diagnostic noted: friction reduced.
