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 are two hot leads
and a ground wire, but no neutral connection, in the
3-wire 240 volt receptacle. A 4-wire receptacle (two
hot, one ground, and one neutral) has been provided
on the control panel for use in temporay power ap-
plications requiring 120/240 volt power. Consult a
licensed electrician for wiring the TemPower plug
and connecting it as temporary service. To con-
nect these units directly to an un-powered, isolated
construction site TemPower panel, have your electri-
cian connect to the control panel using a 120/240
volt, 4-wire twist-lock plug (L14-30P). The use of
locking receptacles and locking plugs provides the
convenience of quick disconnect, for moving, while
allowing workers to safely reconnect the power. In
addition they prevent the plug from being acciden-
tally removed by bumping or vibration.
2. If the generator set is be connected to existing
distribution system a fully isolated manual trans-
fer switch must be installed. 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 genera-
tors. When installing the generator at these sites, a
secondary emergency distribution panel may have
to be installed, such as the Emergency Transfer/Ser-
vice (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 genera-
tor 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 manufac-
turer of these engines has established an excellent
world-wide engine service organization. Engine ser-
vice 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.
1. Change the oil after the fi rst month or 20 hours
of operation and every 6 months or 100 hours there-
after under normal operating conditions. Change
engine oil every 25 hours of operation 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. Remove oil fi ller plug and refi ll with new oil.
Refer to the table in the engine manual for the
proper grade of oil based on your operating tem-
perature.
d. Replace fi ller plug.
2. Checking the Oil Level: The oil level must al-
ways be checked before the engine is started. Take
care to remove any dirt or debris from around the
oil fi ll plug before removing. Be sure the oil level is
maintained. Fill to the “FULL” mark on the dipstick.
3. Dual Element Air Filter: Clean and or replace
foam pre-cleaner and air fi lter every 6 months or 100
hours. Service more often under dusty conditions.
a. Loosen screws and remove cover and air cleaner
assembly from base.
b. Remove foam pre-cleaner by sliding it off the
paper
cartridge.
c. Wash foam pre-cleaner in liquid detergent and
water
d. Wrap foam pre-cleaner in cloth and squeeze dry.
e. Saturate foam pre-cleaner in engine oil. Squeeze
to remove excess oil.
f. Clean Air fi lter using compressed air.
g. Install foam pre-cleaner over air fi lter.
h. Re-install the Air Filter assembly. Reassemble
cover and screw down tight.
Do not use petroleum solvents, such as kerosene, to
attempt to clean the cartridge. They may cause
deterioration of the cartridge. DO NOT OIL CAR-
TRIDGE. DO NOT USE PRESSURIZED AIR TO
CLEAN OR DRY CARTRIDGE.
