Doors: Service and Repair
The mechanical components of the door are lubricated during assembly. If any door hardware mechanism requires additional lubrication use Lubriplate Spray-Lube A, Lubriplate Auto-Lube A or an equivalent. Lubricate the door hinge Pins and the rollers at normal service intervals with 30 weight engine oil. Do not lubricate the surface of the hinge roller that contacts the hold-open link. This may prevent the roller from rolling properly.
