WIRING
Plug your tools such as drills, saws, blowers, sump pump, and
other items to be powered directly into the generator receptacles.
Before plugging in all the tools and cord sets, recheck the rating
of the generator set. Be sure it can handle the intended load and
is compatible with the voltage, phase, and current ratings. ‘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 are
two hot leads and a ground wire, but no neutral connection, in the
3-wire 240Volt receptacle. A 4-wire receptacle (two hot, one ground,
and one neutral) has been provided on the control panel for use in
temporary power applications requiring 120/240 Volt power.
2. If the generator set is connected to an existing distribution system,
a fully isolated manual transfer switch, specifically designed for use
with GFCI, must be installed. The transfer switch prevents damage to
the generator and the 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 this
portable generator. When installing the generator at these sites, a
secondary emergency distribution panel may have to be installed.
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
MAINTENANCE SCHEDULE
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.
CHECKING THE OIL LEVEL
The oil level must always be checked before the engine is started.
Refer to page 5 of this manual for instructions on checking the oil level.
Take care to remove any dirt or debris from around the oil plug before
removing. Be sure the oil level is maintained.
CHANGING THE OIL
Refer to the Maintenance Schedule Chart for required oil change
intervals.
A. Start the engine and warm it up, stop the engine and remove the
spark plug wire to prevent it from accidentally being started.
B. This engine has an oil drain valve for your convenience. Attach a
neoprene hose and drain the oil into an approved container.

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 5 hours of operation
and yearly or 100 hours thereafter under normal op-
erating conditions. Change engine oil every 50 hours
of operation if the engine is operated under heavy
load, or in high ambient temperatures.
a. Start the engine and warm it up, stop the engine
and remove the spark plug wire to prevent it
from accidently being started.
b. Remove oil drain plug at base of the engine
(Ref “B”) and drain the oil into an approved
container.
c. Remove the oil
fi
lter (Ref “C”) and dispose of it
properly.
d. Before you install the new oil
fi
lter, lightly lubri-
cate the oil
fi
lter gasket with fresh clean oil.
e. Install the oil
fi
lter by hand until the gasket
contacts the oil
fi
lter adapter, then tighten the oil
fi
lter 1/2 to 3/4 turns.
f. Replace oil drain plug.
g. Remove oil
fi
ller plug and re
fi
ll with new oil.
Refer to the table on page 5 for the proper
grade of oil based on your operating
temperature.
NOTE: This engine requires 78 to 80 ounces of oil
if it is completely drained. Use caution when re
fi
lling
the engine as some residual oil may have remained
in the engine. Always use the dipstick when
fi
lling
the engine with oil to prevent over
fi
lling.
h. Replace
fi
ller plug.
I. Start the engine and warm it up.
J. After warming up the engine, recheck the oil
level and re
fi
ll as necessary to bring it to the
proper level. See page 5 for proper oil level.
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 annually or every 100
hours. Service more often under dusty conditions.
WARNING: EQUIPMENT DAMAGE
Never start or run the engine with the air
fi
lter re-
moved
a. Loosen snaps (Ref “A”) and remove cover.
