OPERATOR CARE AND MAINTENANCE
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
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.
FILL TO POINT OF OVERFLOWING or on units with
the extended oil fill to the “FULL” mark on the
dipstick.
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 at .030" 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 happens
reform 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.
2. Generator Maintenance - Any major generator
service including the installation or replacement of
parts should be performed only by a qualified
electrical service technician. USE ONLY FACTORY
APPROVED REPAIR PARTS.
a. Bearing - The bearing used in these generators is
a heavy duty double sealed ball bearing. They
require no maintenance or lubrication.
