Section I. OPERATING PROCEDURES
Controls and Instruments
This section describes the various controls and
instruments and provides the operator/crew sufficient
information to insure proper operation of the generator
Controls and Instruments. The purpose of the
controls and instruments and the normal and maximum
reading of the instruments are illustrated in figures 21, 2-
2, and 2-3.
Operation Under Usual Conditions
published for the information and guidance of the
personnel responsible for operation of the generator set.
The operator must know how to perform
every operation of which the generator set is capable
This section gives instructions on starting and stopping
the generator set, operation of the generator set, and on
coordinating the basic motions to perform the specific
tasks for which the equipment is designed.
Since nearly every job presents a different problem, the
operator may have to vary given procedures to fit the
Do not remove setscrew in top of
carburetor for fuel system priming.
Preparation For Starting.
(a) Perform the operators preventive
maintenance checks and services listed in Table 3-2.
(b) Place the three way fuel valve (B, figs.
2-1, 2-2 and E, 2-3) in the SET or AUX position,
depending on the source of fuel.
(c) Place Oil Pan Baffle Rod (D, figure 2-
3) in the proper position depending on ambient
(d) Place air intake shutter (C, fig. 2-3) in
the proper position depending on ambient temperature.
(e) Check load terminals (figure 2-5) for
correct output connections.
Set voltage phase switch (figure 2-6)
for desired output.
(g) Set voltage selector switch (A, figs. 2-
1 and 2-3) to monitor desired phase voltage.
(h) Set current selector switch (A, figs. 2-
1 and 2-3) to monitor desired current.
Turn voltage adjust knob (rheostat),
(A, figs. 2-1 and 2-3) fully counterclockwise.
Place Circuit Breaker in off position (B,
(k) See that the unit is properly grounded
The ground can be in order of
preference, an underground metallic water piping
system, a driven metal rod, or a buried metal place.
A ground rod must have a
minimum diameter of 5/8 inch (1.5875 cm) if solid or ¾
inch (1.905 cm) if pipe, and must be driven to a minimum
depth of 8 feet (240 cm). A ground plate must have a
minimum area of 9 square feet (0.81 square meters) and
be buried to a minimum depth of 4 feet (120 cm). The
ground lead must be NO. 6 AWG (American Wire
Gauge) copper wire bolted or clamped to the rod, plate
or piping system. Connect the other end of the ground
lead to the generator set ground stud (A and B, fig. 2-4).
Do not operate the generator set
connection. Electrical defects in the
unit, load lines, or load equipment
can cause death by electrocution
Use slave receptable when extra
cranking power is required.
(2) Electrical Starting. Start the generator
set as shown in figure 2-7.
(3) Manual Starting. Start the generator
set as shown in figure 2-7.1.
Make sure the circuit breaker is in the
