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.
Grounding
NOTE - These generators sets are shipped with the ground
bonded to neutral. For an isolated ground system remove the
neutral to ground bond in the receptacle panel. Be sure to
reinstall before using the generator as a stand alone unit.
All units must be grounded. Drive a 3/4 or 1" copper pipe or
rod into the ground close to the engine-generator set. The
pipe must penetrate moist earth. Connect an approved
ground clamp to the pipe. Run a No. 10 Awg wire from clamp
to the generator ground lug on the “end cover”. Do not
connect to a water pipe or to a ground used by a radio
system.
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.
1. Change the oil after the first five hours of operation
and every 50 hours thereafter 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 filler plug and refill with new oil.
Refer to the table in the engine manual for the
proper grade of oil based on your operating
temperature.
d. Replace filler plug.
2. 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.
to the “FULL” mark on the dipstick, DO NOT OVER
FILL
3. 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.
4. Dual Element Air Cleaner - Clean and re-oil foam pre-
cleaner at three month intervals or every 25 hours,
whichever occurs first. Service more often under dusty
conditions.
a. Remove knob and cover.
b. Remove foam pre-cleaner by sliding it off the
paper cartridge.
c. Wash foam pre-cleaner in kerosene or 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.
Install foam pre-cleaner over paper cartridge.
Reassemble cover and screw down tight.
Replace the cartridge included with Dual Element Air
Cleaner yearly or every 100 hours. Service more often
if necessary.
5. Spark Plug - Clean and reset gap to the proper gap
every 100 hours of operation. Do not blast clean spark
plug. Clean by scraping or wire brushing and washing
with a commercial solvent. Poor spark will occur if
terminal does not fit firmly on spark plug. If this
happensreform the terminal to fit firmly on spark plug
tip.
GENERATOR CARE
Proper care and maintenance of the generator is necessary
to insure a long trouble free life.
1. Exercising The Generator - The generator should be
operated every three to four weeks. It should be
operated for a period of time sufficient to warm the
unit up and to dry out any moisture that has
accumulated in the windings. If left, this moisture can
cause corrosion in the winding. Frequent operation of
the engine generator set will also insure that the set is
operating properly should it be needed in an
emergency.
