11.5.4.2
Lubrication Requirements. Regular lubrication is required when the basin
is in continuous operation. Intermittent operation may allow an increase in the
lubrication interval. If operating periods are intermittent and infrequent, operate the
mechanism briefly between operating periods and lubricate accordingly. Devices
subject to wide seasonal temperature variations will require seasonal changes in
lubricant grades, especially when summer grade oils thicken at lower temperatures and
reduce the flow capability. Daily or weekly lubrication of operating units is part of the
operator's inspection. The choice of lubricant and its frequency of application are
