WARNING: PERSONAL INJURY
Lead acid batteries produce explosive hydrogen gas
when charging. Keep sparks, flames, and burning
cigarettes away from the battery. Ventilate the area
when charging or using the battery in an enclosed space.
Lead acid batteries contain sulfuric acid, which causes
severe burns. If acid contacts eyes, skin or clothing,
flush well with water. For contact with eyes, get
immediate medical attention
Battery Charging
Units equipped with electric start have a small flywheel
charger built into the engine flywheel assembly for
recharging the starting battery. This flywheel charger
generates a small AC current that passes through a diode
assembly to produce a DC charging current of about 1 to 3
AMP. This circuit is not designed to be used as a battery
charging circuit to recharge dead batteries.
OPTIONAL DOLLY KIT
An optional dolly kit is available for most of these engine
generator sets. The dolly kit comes with instructions and
parts list. After installing the dolly kit, file the instructions and
parts list in the back of this manual for future reference.
LOW OIL LEVEL SHUTDOWN SYSTEM
All WINCO Industrial generators are equipped standard with
low oil shutdown systems. The Honda engines, with the
exception of the GX620, all use a float switch system. This
low oil warning system will automatically stop the engine
before the oil level reaches an critical danger point. This
feature is designed to prevent costly repairs and downtime.
CAUTION: EQUIPMENT DAMAGE
Allowing the engine to shutdown repeatedly
on low oil level may cause excessive wear
which can be cumulative.
This system uses a float in the engine crankcase to sense
the oil level. If a low oil level condition should occur during
operation, the float will ground out the magneto impulse,
“killing” the engine. In addition, there is an indicator light
mounted on the engine shroud near the recoil starter. This
light will blink on and off to indicate a low oil level condition
when you are attempting to start the unit. To get the engine
started, you must add the required amount of oil to the
engine crankcase.
Use of the float 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
unexpected shutdown would cause a safety hazard or
serious inconvenience for the operator.
The Yanmar diesel, Kohler Commander and the Honda
GX620 use a pressurized oil system. The oil pressure is
monitored by an oil pressure sensor mounted on the engine.
If the oil pressure gets low during operation the engine
ignition is grounded out and the engine will shut down. On
the Yanmar engine the oil pressure sensor opens the power
feed to the run solenoid, allowing the fuel rack to close,
shutting the engine down. If during starting the oil system
doesn’t build sufficient pressure to close the oil sensor switch
the engine will not continue to run. This can be caused by a
low oil level or by using the wrong grade of oil for the ambient
air temperature.
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® control switch in the 'Auto' position, the throttle
control lever is electrically released when the load is turned
on so it in no way interferes with the normal governor
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 receptacle 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
field installation.
With the automatic Conserver® switch in the “automatic”
position, the system operates as follows:
1. After the engine has been started, and no electrical
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
flow 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 flow
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 governed 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 appliances 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 voltage being supplied to them. This low
voltage can do permanent damage to these appliances.
