replacement of, rather than repair of, a faulty component.
Two types of organizational maintenance are (1) operator and (2) preventive. Each of the two types should complement the other.
Defects discovered during operation of the unit will be noted for future correction either by the operator or by maintenance personnel, as appropriate. The purpose of preventive maintenance is to keep the machinery running trouble-free. The operator will likely have fewer problems if the preventive maintenance work is done well.
In our previous discussion we have seen that operator maintenance includes many of the tasks you do before, during, and after you operate the generator set to produce power.
As a member of a unit or organization large enough to have a maintenance crew, you may serve as a member of the crew. As a crew member, you will perform organizational preventive maintenance functions on the generator set periodically according to the manufacture's specifications or to service maintenance manuals.
To prevent buildup of contaminants that may cause damage to the operating components or systems of the generator set, you should clean the set periodically. Cleaning operations must be performed only on generator sets that are not operating, that are connected to a parallel bus, or that are connected in a standby mode. To clean the generator set, heed the warnings and cautions given, and proceed as follows:
Compressed air used for cleaning can create airborne particles that may enter the eyes. Pressure shall not exceed 30 psig (206 kPa). Wearing of goggles is required.
Exercise care to prevent dry-cleaning solvent from coming into contact with electrical components.
Painted metal surfaces should be wiped with a clean lint-free cloth moistened with cleaning solvent (P-D- 680, type II). Hard deposits may be scrubbed off with a bristle brush that has been dipped in solvent. Dry the surfaces with a clean lint-free cloth.
Dry-cleaning solvent, P-D-680, type II, is flammable and moderately toxic to the skin and eyes. Respiratory and eye protection are required.
Remove any dust, dirt, or sand from inside the generator set with a damp, lint-free cloth.
Disconnect the battery cables (negative cable first) and remove any corrosion from the battery terminals, cables, and hold-down with a wire brush. Clean the battery filler cap vent holes.
Clean the instrument faces with a clean, lint-free cloth.Continue Reading
