GENERATOR CONTROL PANEL

The following features are mounted on the generator
control panel (Figure 2.1):

2.1.1 FUEL PRIMER

Before starting a cold engine (if it has not been start-
ed in more than two weeks), you must press this
switch for approximately 10 to 15 seconds to bring
fuel from the tank to the carburetor. This rocker type
switch springs back into its original position when
you release it.

2.1.2 START/STOP SWITCH

To crank and start the engine, hold this switch in the
START position. Release the switch when the engine
starts. To stop an operating engine, press and hold
the switch in the STOP position until the engine shuts
off. The switch center position is the RUN position.

2.1.3 FUSE

The fuse protects the engine's DC control circuit
against electrical overload. If the fuse element has
melted open due to overloading, the engine cannot be
cranked. If you must replace the fuse, use only an
identical replacement.

2.1.4 MAIN BREAKER

The main breaker protects the generator's AC output
circuit against overload and provides a method of
turning OFF the generator's 120-volt AC output to the
vehicle circuits. The QUIETPACT 40G has 30-amp
breaker.

OPTIONAL REMOTE
START/STOP PANEL
A remote mounted Start/Stop Panel is available that
allows you to start and stop the generator engine con-
veniently from inside the vehicle.
You can order model 4057 or 4184, a remote panel
that includes a Start/Stop switch, a generator run
lamp and an hourmeter. The hourmeter provides a
continuous indication of engine/generator operating
time. Use the hourmeter for checking off periodic
maintenance requirements on the unit.
2.3

AUTOMATIC CHOKE

The engine is equipped with an automatic choke that
consists of two main components: a choke solenoid
and prechoke.

2.3.1 CHOKE SOLENOID

During engine cranking (Start/Stop switch at
START), a solid-state choke module signals the
choke solenoid to activate and cycle (choke on/choke
off) until the engine starts. The choke solenoid thus
opens and closes the carburetor choke valve only
when the engine is cranking. When the engine starts,
the choke stops cycling.

2.3.2 PRECHOKE

The choke system also has a temperature-sensitive
metal strip that adjusts choke valve angle according
to ambient temperatures (i.e., in cold ambient tem-
peratures, choke valve closes more). Once the engine
starts, an element heats the temperature-sensitive
strip to a normal operating condition, opening the
choke valve. This may take about three minutes in
cooler weather.
2.4

BEFORE STARTING THE ENGINE

Instructions and information in this manual
assume the generator has been properly installed,
connected, serviced, tested and adjusted by a
qualified installation technician or installation
contractor.

2.4.1 INSTALLATION

Generator installation must have been properly com-
pleted so it complies with all applicable codes, stan-
dards and regulations and with the manufacturer's
recommendations.
