ENGLISH 42451
Generator Location
Please consult your local authority. In some areas,
generators must be registered with the local utility.
Generators used at construction sites may be subject to
additional rules and regulations.
This generator must have at least five feet of clearance
from combustible material. Leave at least three feet
of clearance on all sides of the generator to allow for
adequate cooling, maintenance and servicing.
Place the generator in a well-ventilated area. DO NOT
place the generator near vents or intakes where exhaust
fumes could be drawn into occupied or confined
spaces. Carefully consider wind and air currents when
positioning generator.
Grounding
The generator system ground connects the frame to the
ground terminals on the power panel.
Surge Protection
Electronic devices, including computers and many
programmable appliances use components that are
designed to operate within a narrow voltage range and
may be affected by momentary voltage fluctuations.
While there is no way to prevent voltage fluctuations, you
can take steps to protect sensitive electronic equipment.
1. Install UL1449, CSA-listed, plug-in surge suppressors
on the outlets feeding your sensitive equipment.
Surge suppressors come in single- or multi-outlet
styles. They’re designed to protect against virtually
all short-duration voltage fluctuations.
Connecting Electrical Loads
1. Let the engine stabilize and warm up for a few
minutes after starting
2. Plug in and turn on the desired 120 Volt AC single
phase, 60 Hz electrical loads.
– DO NOT connect 3-phase loads to the generator.
– DO NOT connect 50 Hz loads to the generator.
– DO NOT overload the generator.
OPERATION
Voltage fluctuation may impair the proper
functioning of sensitive electronic equipment.
CAUTION
Starting the Engine
1. Make certain the generator is on a flat, level surface.
2. Disconnect all electrical loads from the generator.
Never start or stop the generator with electrical
devices plugged in or turned on.
3. Turn the Fuel Valve to the “ON” position.
4. Flip the ignition switch to the “ON” position.
5. Move the choke lever to the “CHOKE” position.
6. RECOIL START: Pull the starter cord slowly until
resistance is felt and then pull rapidly
7. Do not over-choke. As soon as engine starts, move
the choke lever to the “RUN” position.
If the engine starts but does not run make certain
that the generator is on a flat, level surface. The
engine is equipped with a low oil sensor that will
prevent the engine from running when the oil level
falls below a critical threshold.
NOTE
Keep choke lever in “Choke” position for only 1
pull of the recoil starter. After first pull, move choke
lever to the “Run” position for up to the next 3
pulls of the recoil starter. Too much choke leads to
sparkplug fouling/engine flooding due to the lack of
incoming air. This will cause the engine not to start.
NOTE
Do not operate or store the generator in rain, snow,
or wet weather.
Using a generator or electrical appliance in wet
conditions, such as rain or snow, or near a pool or
sprinkler system, or when your hands are wet, could
result in electrocution.
