acteristics shall not be made. It should not be presumed that<br />
a pressure grease fitting implies the use <strong>of</strong> cup grease. Ordnance<br />
designs frequently employ zerk fittings at points which<br />
require light oil for proper distribution at internal bearings.<br />
Lubricating Freq~ency<br />
3. The frequency <strong>of</strong> lubrication is dependent upon the<br />
use <strong>of</strong> the mechanism. The schedule given is required when the<br />
outfi t is used daily. Lubrication may be less frequent for<br />
less frequent use but in no case shall the maKimum period between<br />
regular inspections <strong>of</strong> the parts for prcper lubrication<br />
on ships in commission eKceed one month.<br />
