BASIC OPERATION
‘Hard Wiring’ this unit directly into a temporary construction
site electrical system is NOT A SIMPLE DO-IT-YOURSELF
JOB. For your safety all wiring must be done by a qualified
electrician and conform to the National Electric Code and
comply with all state and local codes and regulations. Check
with local authorities before proceeding.
WARNING: PERSONAL DANGER
A fully isolated, double pole double throw manual
transfer switch must be installed any time a generator is
being connected to an existing distribution system.
1. These engine generator sets are designed for portable
heavy duty commercial use. Receptacles are provided on
the control panel to permit 120 and 240 volt portable
appliances and tools to be plugged directly into them.
Please note that the 3 wire 240 volt receptacle(s) on these
units are designed to power only 240 volt tools. There is 2
hots and a ground wire, but no neutral connection, in the 3
wire 240 volt receptacle. Split 120/240 volt ‘TemPower’
service requires the use of the L14-30R, 4 wire
receptacle (2 hot, 1 ground, and 1 neutral) provided on
the control panel. Consult a licensed electrician for wiring
the TemPower plug and connecting it as temporary
service.
To connect these units directly to an un-powered, isolated
construction site TemPower panel, have your electrician
connect to the control panel using a 120/240 volt, four
wire twist-lock plug (L14-30P). The use of locking
receptacles and locking plugs provides the convenience
of quick disconnect, for moving, while allowing non
electrical workers to safely reconnect the power. In
addition they prevent the plug from being accidentally
removed by bumping or vibration.
2. If the generator set is connected to existing (electrical)
wiring circuits it is permitted only through a fully isolated
manual transfer switch. The transfer switch prevents
damage to the generator and other circuit components if
main line power is restored while the generator is
connected. Installing a transfer switch also permits the
use of normal fusing.
3. Many homes and construction sites are wired for at
least 60 to 100 Amp entrance service, much greater than
the capacity of these portable generators. When installing
the generator at these sites, a secondary emergency
distribution panel may have to be installed, such as the
Emergency Transfer/Service (ET/S) system available
through your Winco dealer. The emergency distribution
panel must be installed by a licensed electrician according
to all applicable codes. The electrician will move the
critical circuits to be powered during the outage to the
emergency panel. Keep in mind only a limited amount of
amperage is available from the generator set. Some
circuit breakers may still have to be turned off to prevent
an overload on the generator during the initial start up.
See the nameplate on your generator for the amperage
capabilities of your unit.
CAUTION: EQUIPMENT DAMAGE
Failure to properly limit and balance the load applied to
the generator will cause the generator to produce low
voltage and may damage the engine generator set. It
may also cause severe damage to the loads connected
to the generator at that time. Improper loading of the
generator set constitutes abuse and will not be covered
by warranty.
ENGINE CARE
If major engine service or repair is required contact an
authorized engine service center. The manufacturer of
these engines has established an excellent world-wide
engine service organization. Engine service is very likely
available from a nearby authorized dealer or distributor.
Check the yellow pages of your local telephone directory
under “Engines-Gasoline” for the closest engine repair
center or ask the dealer from whom you purchased the
power plant.
Change the oil
After the first five hours of operation and every 25 hours (50
hours for engines with oil filters) thereafter under normal
operating conditions. Change engine oil more often if the
engine is operated under heavy load, or in high ambient
temperatures.
a. Remove oil drain plug at base of the engine and
drain the oil with the engine warm.
b. Replace oil drain plug.
c. Change the oil filter if applicable
d. Remove oil filler plug and refill with new oil.
e. Replace filler plug.
Refer to the table in the engine manual for the
proper grade of oil based on your operating
temperature.
Checking the Oil Level
The oil level must always be checked before the engine is
started. Take care to remove any dirt or debris from around
the oil fill plug before removing. Be sure the oil level is
maintained. FILL TO POINT OF OVERFLOWING or on units
with the extended oil fill to the “FULL” mark on the dipstick.
Cartridge Air Cleaner
Remove and clean cartridge yearly or after every 25 hours,
whichever occurs first. Service more often if necessary.
Clean by tapping gently on flat surface. If very dirty, replace
the cartridge using only original equipment parts available at
any engine service center.
Do not use petroleum solvents, such as kerosene, to
attempt to clean the cartridge. They may cause
deterioration of the cartridge. DO NOT OIL CARTRIDGE,
DO NOT USE PRESSURIZED AIR TO CLEAN OR DRY
CARTRIDGE.
