consider wind and air currents when
positioning generator.
Surge Protection
CAUTION
Voltage fluctuation may impair the proper
functioning of sensitive electronic equipment.
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.
2. Obtain an Uninterruptible Power
Supply (UPS) device.
Most UPS devices come with a
rechargeable battery between the
electronic equipment and power supply
source. The device buffers the voltage
and protects against virtually all short-
duration voltage fluctuations.
Wireless Remote Start
Wireless remote starting is only possible
within 80 feet of the generator.
Do not attempt to adjust the carburetor
choke. The remote system will automatically
close and open the choke.
1. Make certain the generator is on a flat,
level surface.

mounted behind the power panel near
the recoil housing. This light indicates
that the generator is in starting mode.
The light will turn off after the generator
starts.
6. A safety feature is provided which delays
the electrical power availability during
starting mode. The delay lasts for
approximately 15 seconds. The delay is
provided to prevent damage to the
generator if electrical loads are
inadvertently turned on during engine
startup.
7. If the generator fails to start, check the
battery condition and cable connections.
Starting the Engine without
Remote
1. Make certain the generator is on a flat,
level surface.

NOTE
Connecting a generator to your electric utility
company’s power lines or to another power
source may be against the law. In addition this
action, if done incorrectly, could damage your
generator and appliances and could cause
serious injury or even death to you or a utility
worker who may be working on nearby power
lines. If you plan to run a portable electric
generator during an outage, please notify your
electric utility company immediately and
remember to plug your appliances directly into
the generator. Do not plug the generator into
any electric outlet in your home. Doing so could
create a connection to the utility company power
lines. You are responsible for ensuring that your
generator’s electricity does not feed back into the
electric utility power lines.
If the generator will be connected to a building
electrical system, consult your local utility
company or a qualified electrician. Connections
must isolate generator power from utility power
and must comply with all applicable laws and
codes.
Stopping the Engine
1. Turn off and unplug all electrical loads.
Never start or stop the generator with
electrical devices plugged in or turned
