Therefore, the maintenance chapter outlines specific procedures for replacing bulbs, clearing the hook race and feed dogs, and applying proper lubrication. Always ensure the machine is disconnected from its primary power source before opening the casing, adjusting the hook mechanism, or performing any internal maintenance to prevent accidental injury or equipment damage.
