ON REQUIRED TO PREVENT DAMAGE PAINTING Applications of finish paint should be done with care Vents seals gaskets etc should be masked off to avoid plugging and damage due to paint build up After paint has been applied all equipment should be inspected to see that vents have not become plugged and that parts that are to have relative movement have not become painted tight Especially check that the torque limiting devices on drives if supplied have not been glued together by paint Seals and gaskets should be inspected to see that they have not become so stiff from paint build up that they do not seal Warranty charges resulting from inappropriately applied paint will not be accepted 005A 04 11 0 10 GENERAL INFORMATION STAINLESS STEEL BOLTS Where stainless steel bolts and nuts are used in the installation of our equipment the bolt threads should be coated with an anti seize compound such as Never Seez or an equivalent This will reduce the possibility of galling or seizing Renew this coating if repairs require disassembly DRIVES Do not operate any drive unit if its torque overload device is not functioning properly Do not allow excess slack to build up in a drive chain or tighten it to the point that the links cannot flex Be alert to changes in the sound of the operating drives Unusual noises should be investigated Hand contact is not an acceptable method of detecting an overheated motor Provide for overload
