■Lubrication
All machines are generally delivered in their best condition. Efforts shoud be made to keep them that
way. Lack of oil, or the presence of debris or dust, may cause an unexpected failure. To maintain in
optimaloperatingcondition,periodicallycleanthemachineandapplytheproperkindsofoiltoeachpart
in which librication is needed.
Although the frequency of lubrication varies according to how often the machine is used, as a minimum
it is necessary to lubricate before any part becomes dry. It is also necessary to wipe off excessive oil
or it will collect dirt.
