occur during operation, the fl oat will ground out the
magneto impulse, “killing” the engine. To get the
engine started, you must add the required amount of
oil to the engine crankcase. Use of the fl oat system
on applications that are subject to shock, bumping or
severe angles of operation (in excess of 15 degrees)
should be avoided. This is especially true if an un-
expected shutdown would cause a safety hazard or
serious inconvenience for the operator.
AUTOMATIC CONSERVER® CONTROL
(WC Series Only)
The automatic Conserver® control is a gas saving,
solid state system, designed to reduce engine speed
whenever the electrical load is removed from the
generator. Without a slow down control, the engine
would run at full speed at all times, regardless of the
electrical load. With the automatic Conserver® con-
trol switch in the “ON” position, the throttle control
lever is electrically released when the load is turned
on so it in no way interferes with the normal gover-
nor operation. When the load is turned off, the idle
magnet energizes and reduces the engine speed. It
does not cause incorrect operation of the carburetor
or governor, but neither does it correct them.
The automatic Conserver® control consists of a
solid state module mounted in the generator recep-
tacle box, a switch, resistor and an electromagnet
mounted on the engine near the throttle lever. The
automatic Conserver® control is only offered as a
factory installed feature. It is not available for fi eld
installation.
With the automatic Conserver® switch in the “ON”
position, the system operates as follows:
1. After the engine has been started, and no electri-
cal load is applied, the solid state module senses
this condition and turns on the electromagnet. This
will pull and hold the throttle lever, closing the throttle
on the carburetor reducing the engine speed.
2. When a load is applied to the generator, the
current fl ow to the load is sensed by the solid state
control module and the electromagnet is turned off.
This releases the throttle arm allowing the governor
to take over and open the throttle. The engine will
respond and come up to the governed speed (3600
rpm).
3. When the electrical load is turned off, the control
module will sense that there is no longer any current
fl ow and the automatic idle control will once again
energize the electromagnet, pulling and holding the
throttle. When the automatic Conserver® switch is
in the “OFF” position, the engine will run at full gov-
erned speed regardless of the generator load.
CAUTION: EQUIPMENT DAMAGE
When using these generators to power a home
or construction trailer the Conserver® switch
should be left in the off position. Some applianc-
es in homes and construction trailers have such
a low current draw (less that 100 watts) they will
not turn the conserver off, resulting in low volt-
age being supplied to them. This low voltage
can do permanent damage to these appliances.
INITIAL START UP
The throttle control on these generators is preset
and locked to operate at 3600 RPM (nominal) with
no load speed set at 3750 RPM. Only a trained
service technician should be allowed to adjust this
speed setting.
NOTICE: ENGINE START LOCKOUT
This unit will not start if it is low on oil. The lu-
bricating oil level must be at the full mark before the
engine will start and run.
BASIC OPERATION
MANUAL STARTING
Refer to the engine manual for additional starting,
operating, and stopping instructions.
1. Turn on the fuel supply
2. Turn the ON/OFF switch to the “ON” position.
3. Move the choke to the full “on” position.
4. Pull the starter grip lightly until resistance is felt,
then pull briskly.
5. When the engine starts, open the choke grad-
ually.
6. The engine should promptly come up to operating
speed.
NOTICE:
Do not allow the starter grip to snap back against
the engine. Return it gently to prevent damage to
the starter.
ELECTRIC STARTING
If the engine is cold and stiff or if the battery is not
fully charged, starting can be made easier by slowly
hand cranking the engine through the compres-
sion stroke before pushing the starter switch. This
permits the starter to gain momentum before the
heavy load of the compression stroke occurs. This
