Don’t Overload Generator
Make sure you can supply enough rated watts and surge watts for all electrical loads connected to the generator. Rated
watts refer to the power a generator must supply to keep a device running. Surge watts refer to the power a generator
must supply to start an electrical device. This power surge for starting a device usually lasts between 2-3 seconds but
this additional output must be considered when selecting the electrical devices, you plan to attach to the generator. To
prevent overloading the generator, take the following steps:
1. Add the total rated wattage of all electrical devices that will be connected to the generator simultaneously.
2. Estimate surge watts by adding the item(s) with the highest output (it is unnecessary to calculate the surge output for
all devices as they should be connected one at a time).
3. Add the Surge Watts to the total Rated Watts in step 1. Keep total load within generator’s power capacity.
Never exceed generator’s wattage / amperage capacity. This could damage the generator
and / or connected electrical devices.
WARNING!
• Check operating voltage and frequency requirements of all electrical devices prior to plugging them into the generator.

Carburetor Adjustment
The carburetor is low emission and is equipped with a non-adjustable idle mixture valve. If adjustment is needed contact an
authorized dealer.
Replacing Fuel Filter ( If Applicable)
Occasionally the fuel filter may become clogged and need replacing. To purchase a replacement fuel filter contact
PULSAR customer service or your local small engine repair shop.
Fuel tank must be empty before replacing fuel filter. Run unit until tank is empty, if needed,
or inspect filter prior to fill-up.
CAUTION!
Spark Arrestor (See Fig 17 If Applicable)
• Inspect the spark arrestor for breaks or holes. replace if necessary. To purchase a replacement spark arrestor contact
PULSAR customer service.
• Use a brush to remove carbon deposits from the spark arrestor screen as needed.
• To remove the spark arrestor: While the muffler is cool, loosen the locking clamp and slide the spark arrestor out of the
muffler. Reverse this process to install it.
Draining Fuel Tank and Carburetor
To help prevent varnish deposits in the fuel system, drain the fuel from the tank and carburetor before storing the unit for
long periods of time. This will help prevent starting problems in the future. If the unit is stored with fuel and the fuel
becomes stale or turns gummy or to varnish the warranty does not cover this repair or service.

Storage
• Remove any debris that has collected on the generator and around the muffler and controls. Use a vacuum cleaner to
pick up loose debris. If dirt is caked on, use a soft bristle brush.
• Inspect air cooling cylinder fins and flywheel fan. Remove any debris if obstructed.
• For short-term storage, start generator once every 7 days.
• For long-term storage, add fuel stabilizer to prevent stale fuel from causing acid and gum deposits in the fuel system
and carburetor.
• Store ina sheltered location and use a protective cover to suitable from dust.
Draining the fuel tank
• Turn the fuel valve to the OFF position.
• Turn the engine OFF
• Push the fuel valve knob through the valve holder bracket allowing you to access the petcock.
• Remove the fuel line that leads from the carburetor to the petcock by squeezing the ends of the hose clamps and
sliding the fuel line off.
• If needed, install a fuel hose that will extend to a suitable fuel container large enough to catch the fuel being drained
from the tank.
• Turn the fuel valve to the ON position and open the fuel tank cap slightly to equalize pressure.
• When the fuel has drained from the tank, close the fuel valve and reinstall fuel line securely on petcock.
• Reinstall the fuel valve knob in the valve bracket. Push forward until knob snaps securely into position.
Draining the carburetor
• Turn the fuel valve to the OFF position.
• Turn the engine OFF.
• Position a suitable container under the carburetor drain screw to catch fuel; loosen and remove the screw.
• Allow fuel to drain completely into container, be sure to wipe up any spilled fuel right away.
• Retighten drain screw, taking care that the gasket seal is in place.
Consult local hazardous waste management in your area for the proper way to dispose of
used fuel.
CAUTION!

CO SENSOR
25
CO SENSOR
The CO Sensor monitors for the accumulation of poisonous carbon monoxide gas around the generator when the engine
is running. If increasing levels of CO gas are detected, the CO Sensor automatically shuts down the engine.
The CO Sensor will also detect the accumulation of carbon monoxide from other fuel burning sources used in the area of
operation. For example, if the exhaust of fuel burning tools is pointed at a CO Sensor-equipped generator, a shut-off may
be initiated due to rising CO levels. This is not an error. Hazardous carbon monoxide has been detected. Move and
redirect any additional fuel burning sources to dissipate carbon monoxide away from personnel and occupied buildings.
Note: Remote start-equipped generators must be restarted with the START/STOP button on the control panel after an
automatic shut-down occurs.
Generators are intended to be used outdoors, far from occupied buildings and the exhaust pointed away from personnel
and buildings. If misused and operated in a location that results in the accumulation of CO, like in a partially enclosed area,
the CO Sensor shuts off the engine, notifies the user with a RED indicator light, and directs the user to read the Action
Label for steps to take. The CO Sensor DOES NOT replace carbon monoxide alarms. Install battery-powered carbon
monoxide alarm(s) in your home.
CO SENSOR INDICATOR LIGHTS
RED
Carbon monoxide accumulated around the generator. After shut-off, the RED indicator light in the CO Sensor area of the
control panel will flash to provide notification that the generator was shut-off due to an accumulating CO hazard. The RED
light will flash for at least five minutes after a CO shut-off.
Move the generator to an open, outdoor area far away from occupied spaces with exhaust pointed away. Once relocated to
a safe area, the generator can be restarted. Introduce fresh air and ventilate the area where the generator had shut down.
YELLOW
A CO sensor system fault occurred. When a system fault occurs, the generator is automatically shut down and the
YELLOW indicator light in the CO auto-shutoff area of the control panel will flash to provide notification that a fault has
occurred. The YELLOW light will flash for at least five minutes after a fault. The generator can be re-started, but may
continue to shutoff. A CO sensor fault can only be diagnosed and repaired by an authorized Pulsar service center.
