Description
The DuroMax CO-ALERT system was created to protect
our customers and their families from dangerous carbon
monoxide. Just like the detector for your home the CO-
ALERT tests the air for to keep you safe and healthy.
CO Detected
If dangerous carbon monoxide levels are detected:
Generators are convenient, but they can also be dangerous. All fuel-
burning appliances and equipment release a poisonous gas called carbon
monoxide.
Carbon monoxide (also known as CO) can be dangerous for humans
and pets, even in small amounts, because it blocks oxygen from getting
into your body. Carbon monoxide poisoning can lead to death in a very
short time. It is odorless, tasteless and invisible, so you may be exposed
without knowing it. That is why carbon monoxide is sometimes called
“the silent killer.”
As the only safe way to use a portable generator, taking your
generator outside is absolutely mandatory to keep your family
safe from carbon monoxide. But there’s even more you can do.
By educating yourself about all carbon monoxide risks, you’ll
be better prepared to protect your family from this colorless,
odorless threat. Visit takeyourgeneratoroutside.com for more
information.

25
Step 4 - Adding Oil
Add oil
The generator requires engine oil to operate properly. The generator, when new from the package,
contains no oil in the crankcase
*
. You must add the proper amount of oil before operating the
generator for the rst time. This amount is equal to the oil capacity of the engine crankcase:
WARNING: Do not apply engine oils with additives or 2-stroke gasoline engine oils;
they don’t have enough lubrication and may shorten the engine’s service life.
a. Make sure the generator is on a level surface.
b. Unscrew the oil ller/dipstick cap from the engine.
c. Using a funnel, add the appropriate amount of oil
into the crankcase. You will know the crankcase is
full when the oil level has reached the lower lip of
the opening you have just poured the oil into.
d. Replace the oil ller cap.
Engine oil recommended: SAE 10W-30.
Viscosity varies with regions and temperatures. Choose your
oil viscosity using the chart to the left.
* A small amount of oil from factory testing may be present on
arrival.
* Synthetic oil may be used after the 8 hour initial break-in
period. Using synthetic oil does not increase the recommended
oil change interval. Full synthetic 5W-30 oil will aid in starting in
cold temperatures <5ºC (41ºF).
Model Number DS13000DX
Engine Oil Capacity 40.5 . oz (1.2 L)
WARNING: Do not overll the crankcase. This
may damage the motor and shorten the overall
life of your generator.
26
GENERATOR SETUP (CONTINUED)
Step 5 - Adding Gasoline (Optional)
Add gasoline
a. Make sure the generator is on a level surface.
b. Unscrew gas cap and set aside (NOTE: the gas cap
may be tight and hard to unscrew).
c. Slowly add unleaded gasoline to the fuel tank. Be
careful not to overll. The fuel gauge on the top of
the gas tank indicates how much gasoline is in the
generator gas tank.
d. Replace fuel cap and wipe up any spilled gasoline
with a dry cloth.
IMPORTANT:
● To ensure that the generator runs smoothly use only FRESH, UNLEADED GAS WITH AN
OCTANE RATING OF 87 OR HIGHER.
● Never use an oil/gasoline mixture. Never use old gas.
● Avoid getting dirt or water in the fuel tank.
● Gas can age in the tank and make it hard to start up the generator in the future.
● Never store generator for extended periods of time with fuel in the tank.
Model Number DS13000DX
Gas Tank Capacity 8.3 US gal. (31 L)
DANGER
DO NOT OVERFILL
THE GAS TANK
OVERFILLING CAN RESULT
IN A FIRE, EXPLOSION,
OR DEATH.
1.5”
WARNING: Gas can expand. Do not ll the gas tank to the very top. Leave a
minimum of 1.5 in open space. Gasoline and gas fumes are highly ammable.
Do not ll the tank near an open ame. Always check for fuel spills.
27
Step 6 - Grounding the Generator
Attach grounding wire
a. Ground the generator by tightening the grounding
nut against a grounding wire.
b. Connect the other end to a copper or brass
grounding rod that’s driven into the earth.
A generally acceptable grounding wire is a No. 12 AWG
(American Wire Gauge) stranded copper wire.
Grounding codes can vary by location. Please contact a local
electrician to check the grounding regulations for your area.
Note: If the generator is connected to a home, then it
won’t be necessary to attach the separate grounding
wire and you can opt to use your home ground instead.
Please see a certied electrician for further options with
grounding your generator.
WARNING: Failure to properly ground the generator can result in electrocution.
High Altitude Operation
At high altitudes, the standard carburetor air/fuel mixture will be too rich. The performance will decrease,
and fuel consumption will increase. A very rich mixture will also foul the spark plug and cause hard starting.
Operation at an altitude that diers from that at which this engine was certied, for extended periods of
time, may increase emissions. High altitude performance can be improved by specic modications to the
carburetor. If you always operate your generator at altitudes above 3,000 feet (900 meters), have a dealer
perform this carburetor modication. This engine, when operated at high altitude with the carburetor
modications for high altitude use, will meet each emission standard throughout its useful life. Even with
carburetor modication, engine horsepower will decrease by about 3.5% for each 1,000-foot (300-meter)
increase in altitude. The eect of altitude on horsepower will be greater than this if no carburetor
modication is made.
When the carburetor has been modied for high altitude operation, the air/fuel mixture will be too lean
for low altitude use. Operation at altitudes below 3,000 feet (900 meters) with a modied carburetor may
cause the engine to overheat and result in serious engine damage.
28
29
STARTING THE GENERATOR
If this is not your rst time using the generator there are still steps you should take to prepare it for
operation each time you use it.
IMPORTANT: At this point you should be familiar with the procedures described in the rst
portion of this section entitled “GENERATOR SETUP” If you have not yet read this section, go
back and read it now.
30
BEFORE YOU START YOUR GENERATOR
Step 1 - Check the Oil
Check the oil
The generator is equipped with an automatic shuto to
protect it from damage due to low oil. Nonetheless, you
should check the oil level of the engine before each use to
ensure that the engine crankcase has a sucient amount.
To check the oil level:
a. Make sure the generator is on a level surface.
b. Unscrew the oil ller/dipstick cap.
c. With a dry cloth, wipe the oil o of the stick on the
inside of the cap.
d. Insert the dipstick as if you were replacing the
cap and then remove it again. There should now be
oil on the stick. If there is no oil on the stick, or oil
only at the very end of the stick, you should add
oil until the engine crankcase is lled (see “Adding
Oil” portion of the “Maintenance” section).
e. Be sure to replace the cap when nished checking
oil.

USING THE GENERATOR
If this is not your rst time using the generator there are still steps you should take to prepare it for
operation each time you use it.
IMPORTANT: At this point you should be familiar with the procedures described in the rst
portion of this section entitled “GENERATOR SETUP” If you have not yet read this section, go
back and read it now.
USING THE GENERATOR
AC Usage
The total running wattage requirement of the electrical devices connected to the generator should
not exceed the rated wattage of the generator itself. To calculate the total wattage requirement of
the electrical devices you wish to connect, nd the rated (or running) wattage of each device. This
number should be listed somewhere on the device or in its instruction manual.
If you cannot nd this wattage, you may calculate it by multiplying the voltage requirement by the
amperage drawn: watts = volts x amps. If these specications are not available, you may estimate
the watts required by your device by using the chart on the next page.
Once you have found the rated wattage requirement of each electrical device, add these numbers
to nd the total rated wattage you wish to draw from the generator. If this number exceeds
the rated wattage of the generator, DO NOT connect all these devices. Select a combination of
electrical devices, which has a total rated wattage lower than or equal to the rated wattage of the
generator.
42
● You may connect electrical devices running on AC current according to their wattage
requirements.
● The chart below shows the rated and surge wattage of your generator according to its model
number.
● The rated wattage corresponds to the maximum wattage the generator can output on a
continuous basis.
● The surge wattage corresponds to the maximum amount of power the generator can output
for a short period of time. In addition to the rated wattage listed by the device, many electrical
devices such as refrigerators require short bursts of extra power to stop and start their motors.
The surge wattage ability of the generator covers this extra power requirement.

deny you warranty coverage if your small o-road engine or a part has failed due to abuse, neglect,
or improper maintenance or unapproved modications.
