LOCATION
For best service from your stationary generator set there are several factors which should be taken
into consideration when choosing the best location in which to permanently mount it:
MOISTURE: All electrical equipment should be protected from excessive moisture. Failure to do so
will result in deterioration of the insulation and may result in short circuits and a possible
electrocution hazard.
OPERATING ELECTRICAL EQUIPMENT IN WET ENVIRONMENTAL
CONDITIONS CREATE A POTENTIAL ELECTROCUTION HAZARD.
DO NOT OPERATE ELECTRICAL EQUIPMENT WHILE STANDING IN
WATER, ON WET GROUND, OR WITH WET HANDS OR SHOES.
DIRT: Foreign materials such as dust, sand and other abrasive materials have a tendency to cause
excessive wear to both engine and generator parts. It is important that the unit be operated in a
reasonably clean environment.
HEAT: All engines give off considerable heat when running. Since the engine and your generator
set uses air to keep it cool it is important that the temperature of the area in which it is located is
does not exceed 100
boost circulation should be utilized.
EXHAUST: Exhaust Gases from internal combustion engines are extremely poisonous. Whenever an
engine is run indoors the exhaust fumes must be vented to the outside.
CONFINED SPACE: This unit must not be operated in a confined space or an enclosed compartment
/ area. Running the generator set in this environment is a potential fire hazard and is not authorized.
Engine and generator overheating damage could also occur due to restricted cooling airflow to and
from the unit.
o
F (even while it is running). Where natural ventilation is inadequate a fan to
EXHAUST FUMES CAN CAUSE SEVERE INJURY OR DEATH. ALWAYS
OPERATE IN A WELL-VENTILATED AREA.
OPERATING THIS UNIT IN AN AREA WITHOUT ADEQUATE
VENTILATION CREATES A POTENTIAL FIRE HAZARD. ALWAYS
OPERATE THIS UNIT IN A WELL-VENTILATED AREA.

CONNECTIONS
WIRING: Use sufficiently large insulated wire to connect the generator set to the load. The gauge
of the wire will depend largely on the distance, the permissible voltage drop, and the size and type of
load. If you are not sure of the gauge wire needed for your application, consult a competent
electrician.
GROUNDING: If grounding is necessary in your application according to National Electric Code
and/or local codes, drive a 3/4" or 1" pipe into the ground as close to the generator
Set as is possible. This pipe must penetrate moist earth (minimum of 8 feet). Connect a ground clamp
to this pipe and run a No. 10 wire or larger from it to the ground stud on the generator set.
Do not connect the ground wire from the generator set to a water pipe or a ground used by a radio
system.
CONNECTIONS TO HOUSE WIRING: Any electrical generator that is temporarily
building or home (where the building is also supplied electricity by a local utility) shall be connected
only by a competent electrician and only after the main service entrance switch has been
disconnected and locked open
electrical transmission wires and prevent the hazard of electrical back-feed to utility service workers.
Any generator set that is permanently
supplied electricity by a local utility) shall be connected only by means of a double- throw transfer
switch. This will isolate the building's electrical system from the local utility's electrical transmission
wires and prevent the hazard of electrical back-feed to utility service workers.
CHECK ALL NATIONAL ELECTRIC CODES AND ALL LOCAL CODES IN REGARDS TO YOUR SPECIFIC
APPLICATION. ANY NATIONAL ELECTRIC CODE OR LOCAL CODE WILL TAKE PRECEDENCE OVER
ANY OF OUR GUIDELINES OR RECOMMENDATIONS.
FRAYED, CUT, BROKEN, LOOSELY CONNECTED, OR IMPROPERLY
SIZED POWER CORDS OR WIRES CAN CAUSE EQUIPMENT DAMAGE,
FIRE, SEVERE INJURY OR DEATH. INSPECT AND MAINTAIN ALL
POWER CORDS ON A REGULAR BASIS.
IMPROPER GROUNDING CAN CAUSE EQUIPMENT DAMAGE, SEVERE
INJURY OR DEATH. INSPECT AND MAINTAIN THE GROUNDING

ENGINE INFORMATION
This operator's manual only covers basic day-to-day engine operating instructions. However, the
engine manufacturer's manual is included with your generator set and should be referred to for any
additional information you may need. Become familiar with and follow all the engine manufacturer's
operation, safety and maintenance guidelines.
OIL: Use a high quality oil of the type specified in the engine owner's manual for your specific
operating conditions. Check the oil regularly, or at minimum every 5-8 hours of operation.
TO HELP PREVENT ENGINE DAMAGE, CHECK THE OIL LEVEL OF THE ENGINE
REGULARLY AND MAKE SURE IT IS MAINTAINED AT THE PROPER LEVEL.
FUEL: (Gasoline or Diesel): Fill the fuel tank prior to operation. Use a clean fuel of the
type and specification mentioned in the engine owner's manual. Do not mix oil with the fuel. Never
fuel the engine while it is running or hot as any spilled fuel may ignite on the hot surfaces. Always
shut the engine off and allow it to cool down before refueling it.
SPILLED FUEL MAY IGNITE AND CAUSE PROPERTY DAMAGE, SEVERE
INJURY OR EVEN DEATH IF IT WOULD COME INTO CONTACT WITH ANY
HOT SURFACE. NEVER REFUEL AN ENGINE WHILE IT IS HOT OR RUNNING.
ALWAYS CLEAN UP ANY SPILLED FUEL AND ALLOW IT TO DRY PRIOR TO
STARTING AN ENGINE.
FUEL (L.P. or Natural Gas): Make sure the gaseous fuel being supplied to the unit is in vapor form
and that it is being delivered to the engine's gaseous fuel regulator at the pressure specified on it. An
engine needs 10,000 BTU's of fuel per each engine horsepower to operate properly.
GASEOUS FUEL IS EXTREMELY FLAMMABLE AND CAN CAUSE PROPERTY
DAMAGE, SEVERE INJURY OR DEATH. CHECK THE GASEOUS FUEL SUPPLY
SYSTEM ON A MONTHLY BASIS FOR LEAKS. HAVE ANY LEAKS REPAIRED
BY AN EXPERIENCED PROFESSIONAL PRIOR TO STARTING YOUR
GENERATOR SET.
OPERATING SPEED: This generator set must be run at it's proper speed in order to obtain the
electrical power it was built to produce.
All engines have a tendency to slow down when a load is applied to it. The governor on the engine is
designed to hold the operating speed as nearly constant as possible. When the load connected to the
generator set is increased, the engine is more heavily loaded and as a result the engine speed drops
slightly. This slight decrease in engine speed results in a slight decrease in generator voltage and
frequency output. This voltage and frequency variation has no appreciable effect in the operation of
motors, lights, and most appliances and tools. However, timing devices and clocks will not keep
perfect time when used on this generator.
