Section 2
Operation
2-l. GENERAL
Operation of the generator set is controlled by a single
switch on the controller (Figure 2-l). This switch is a
momentary contact, three-position, start-run-stop switch.
It is spring loaded to return to the center (run) position
when released from either the start or stop position. This
switch must be held in the desired position until the unit
is running or has come to a complete stop. The controller
includes a keyed connector for starting and stopping the
set at an optional remote switch located inside the vehicle.
2-2. PRESTART CHECKLIST
Refer to Table 2-l for all prestart checks.
CHECK REQUIREMENT
Oil Level Near Full (Not Over)
Air Inlets Unobstructed
Compartment Clean
Air Cleaner Clean, Properly Installed
Air Shrouding
Tight, Proper Position
Exhaust System Unobstructed, Properly
lnstal led
Electrical Connections Clean and Tight

2-3. OPERATION
NOTE
If the generator set shuts itself down due to
high engine temperature or low oil pressure,
the cause must be located and eliminated
before the set can be restarted. Also, make
sure the circuit breaker(s) is in the “on” posi-
tion so generator output is transferred to the
load.
CAUTION
In the event of a “false start”, that is, the en-
gine gets up sufficient speed to disengage the
starter but fails to continue running, allow the
engine to come to a complete halt before
making a restart attempt. If the flywheel is
still rotating when the starter is engaged, the
starter pinion and ring gear will clash which
may damage the ring gear teeth.

‘I. Move the START-STOP switch on the controller to
START position and hold until the engine is running but
not more than 10 seconds. Normally the engine will start
within five seconds. If the engine does not start in 10 sec-
onds, release the switch and wait a few seconds before mov-
ing back to START position. This allows the choke to reset
in the full choke position.
2. Whenever possible allow a brief cooling period by run-
ning the set at low or no load for a few minutes just prior
to shutdown. To stop, move the switch to STOP position
and hold until the set comes to a complete halt.
