GASOLINE
When using gasoline always use a good grade of
unleaded fuel. This engine is certifi ed to operate on
unleaded gasoline with a pump octane rating of 86
or higher. Gasoline containing no more than 10%
ethanol (E10) or 5% methanol by volume may be
used. In addition methanol must contain co-solvents
and corrosion inhibitors. Use of fuels with content of
ethanol or methanol greater than shown above may
cause starting and/or performance problems. Always
insure that the fuel is clean and free of all impurities.
WARNING: FIRE DANGER
Gasoline and its fumes are VERY explosive when
proper precautions are not taken.
Never use gasoline that has been stored for an ex-
tended period of time as the fuel will lose it’s volatile
properties and you will be left with only the varnish
residue. The varnish like substance will clog the
carburetor and will not burn properly.
The use of fuel additives, such as STA-BIL, or an
equivalent will minimize the formation of fuel gum
deposits. If a a unit has been out of operation for
an extended period of time it is best to drain old fuel
from the engine and replace with fresh fuel before
attempting to start.
BATTERY INSTALLATION
(WC6000HE)
All electric start engine generator sets are shipped
with a battery kit for customer installation. This kit
consists of a battery tie down, hardware, and instruc-
tion sheet for installation. After installing the battery
rack, fi le the instruction sheet in the back of this
manual for future reference.
If you intend to use the power plant’s electric start
system, you will need to purchase and install a bat-
tery to operate it. Units equipped with a recoil or
rope start will operate satisfactorily without a battery.
A twelve volt battery,
BCI group U1 rated at 235
CCA
or larger is recommended for this electric start
engine generator set. Follow the battery manufac-
turers recommendations for servicing and charging
prior to use. Connect the battery to the electric start
system using the cables provided.
CAUTION: EQUIPMENT DAMAGE
These electric start engines are NEGATIVE
GROUND. Use extreme caution when connecting the
battery. Connect the NEGATIVE battery terminal to
GROUND.
For your safety always connect the positive battery
cable to the “bat+” terminal fi rst. Then connect the
negative battery cable to the “bat-” terminal. Make
sure all connections are clean and tight. Reverse
the sequence when disconnecting, disconnect the
negative cable fi rst. These engines produce enough
direct current to keep a battery charged under nor-
mal operating conditions, but were not intended to
be used as a battery charger.
WARNING: PERSONAL INJURY
Lead acid batteries produce explosive hydrogen
gas when charging. Keep sparks, fl ames, 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, fl ush well with water. For con-
tact with eyes, get immediate medical attention.
BATTERY CHARGING
Units equipped with electric start have a small fl y-
wheel charger built into the engine fl ywheel assem-
bly for recharging the starting battery. This fl ywheel
charger generates a small AC current that passes
through a diode assembly to produce a DC charg-
ing current of about 1 to 3 AMPS. 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 the WC5000H,
WC6000H and WC6000HE generator sets. The
dolly kit comes with instructions and parts list. After
installing the dolly kit, fi le the instructions and parts
list in the back of this manual for future reference.
OIL ALERT SYSTEM
All WINCO Industrial generators are equipped
standard with low oil shutdown systems. The Honda
engines all use a fl oat 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 fl oat in the engine crankcase to
sense the oil level. If a low oil level condition should
