Frequently Asked Questions - XP12000E DuroMax

What type of oil should I use in my XP12000E generator?

Use SAE 10W-30 engine oil. The oil capacity is 40.5 fl oz (1.2 L). Do not use additives or 2-stroke oil. For cold temperatures below 41°F, synthetic 5W-30 is recommended after the break-in period.

How do I start the generator using electric start?

Ensure the breaker is OFF, turn the fuel valve ON, close the choke, turn idle control OFF, then turn the key switch to START for up to 5 seconds. Once started, open the choke and turn the breaker ON.

Can I connect the generator directly to my home's electrical panel?

Yes, but only with a transfer switch or interlock kit installed by a qualified electrician. Never connect directly without these devices to avoid backfeeding and electrocution risk.

What should I do if the generator runs but there is no electrical output?

Check that the main circuit breaker is ON. Inspect extension cords for damage. Verify that the connected device is working. If still no output, the carbon brushes or AVR may need inspection.

How often should I change the oil?

Change the oil after the first 8 hours (break-in), then every 3 months or 50 hours of heavy use, or every 6 months or 100 hours of normal use.

What does the CO Alert system do?

The CO Alert system monitors carbon monoxide levels. If dangerous CO is detected, the indicator lights red and the engine automatically shuts down. It will not restart for 5 minutes. A yellow light indicates system maintenance required.

Can I use the generator in the rain?

No. The generator should not be operated in rain or wet conditions unless it is covered and the outlets are protected. Always use a GFCI in conductive areas.

How do I store the generator for more than 30 days?

Turn off the breaker and run the generator dry by shutting the fuel valve. Drain the gas tank and carburetor. Remove the spark plug, add 2 tablespoons of oil to the cylinder, pull the recoil to lubricate, and reinstall the plug. Remove the battery and charge it indoors.

What size extension cord should I use?

Use the correct wire gauge based on length and amperage. For 120V 15A up to 50 ft, use 14 gauge; for 240V 30A up to 50 ft, use 10 gauge. Always use twisted copper wire for maximum reliability.

Is the generator dual fuel?

No, the XP12000E is gasoline only. However, DuroMax offers dual fuel models like the XP13000HX that run on gasoline or propane.

DANGER

Using a generator indoors CAN KILL YOU IN MINUTES. Generator exhaust contains carbon monoxide. This is a poison you cannot see or smell.

NEVER use inside a home or garage, EVEN IF doors and windows are open.

Avoid other generator hazards. READ MANUAL BEFORE USE

CARBON MONOXIDE SAFETY

Carbon Monoxide

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."

CO ALERT

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:

• The indicator will light red.
• The engine will shutdown.
• The engine will not restart for 5 minutes.

Maintenance Required

If an error in the CO ALERT system is detected the indicator will light yellow. Please contact DuroMax service at 844-DUROMAX for assistance.

ALWAYS READ THE OWNER'S MANUAL FIRST

4. Reinstall the battery plate

a. Cover the connected terminal with the black rubber boot. b. Reinstall the battery cover plate using the wrench from the toolkit.

Step 4 - Adding 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 first time. This amount is equal to the oil capacity of the engine crankcase:

Model Number XP12000E

Engine Oil Capacity 40.5 fl. oz (1.2 L)

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.

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 < 5^ (41°F).

Close-up of a hand holding a yellow tool interacting with an electrical component (no visible text or symbols)

Add oil

a. Make sure the generator is on a level surface.
b. Unscrew the oil filler/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 filler cap.

Step 5 - Adding Gasoline

Person pouring liquid into a red gas cylinder on a black tray (no visible text or symbols)

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 overfill. 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.

Model Number XP12000E
Gas Tank Capacity 8.3	US gal. (31 L)

WARNING: Gas can expand. Do not fill the gas tank to the very top. Leave a minimum of 1.5 in open space. Gasoline and gas fumes are highly flammable. Do not fill the tank near an open flame. Always check for fuel spills.

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.

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 certified 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 differs from that at which this engine was certified, for extended periods of time, may increase emissions. High altitude performance can be improved by specific modifications to the carburetor. If you always operate your generator at altitudes above 3,000 feet (900 meters), have a dealer perform this carburetor modification. This engine, when operated at high altitude with the carburetor modifications for high altitude use, will meet each emission standard throughout its useful life. Even with carburetor modification, engine horsepower will decrease by about 3.5% for each 1,000-foot (300-meter) increase in altitude. The effect of altitude on horsepower will be greater than this if no carburetor modification is made.

When the carburetor has been modified 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 modified carburetor may cause the engine to overheat and result in serious engine damage.

STARTING THE GENERATOR

If this is not your first 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 first portion of this section entitled "GENERATOR SETUP" If you have not yet read this section, go back and read it now.

BEFORE YOU START YOUR GENERATOR

Step 1 - Check the Oil

Close-up of a hand holding a yellow connector into an electrical enclosure (no visible text or symbols)

Close-up of a metallic pipe fitting with a yellow liquid inside, no visible text or symbols

Check the oil

The generator is equipped with an automatic shutoff 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 sufficient amount.

To check the oil level:

a. Make sure the generator is on a level surface.
b. Unscrew the oil filler/dipstick cap.
c. With a dry cloth, wipe the oil off 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 filled (see "Adding Oil" portion of the "Maintenance" section).
e. Be sure to replace the cap when finished checking oil.

Model Number XP12000E

Engine Oil Capacity 40.5 fl. oz (1.2 L)

Step 2 - Check the Gas Level

Person pouring liquid into a red gas cylinder on a blue tray (no visible text or symbols)

Check fuel level

If running the engine on gasoline check to see that there is sufficient gasoline in the fuel tank. The fuel gauge on top of the tank will give a rough estimate of the gasoline level. The gauge will appear white then fill red as the tank is filled.

Note: Fuel gauge may not register with less than 1/3 fuel tank full.

WARNING: Gasoline and gasoline fumes are highly flammable.

• Do not fill the tank near an open flame.
  • Always allow the engine to cool for several minutes before refueling.
• DO NOT overfill the fuel tank. Fuel expands when shaken or heated. ALWAYS leave 1^1/2 space or more at the top of the tank.
• ALWAYS use fresh fuel or stabilized fuel. Old gasoline (older than 30 days) can cause permanent damage to the fuel system.
  • Always check for fuel spills.

USING THE GENERATOR

If this is not your first 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 first portion of this section entitled "GENERATOR SETUP"; if you have not yet read this section, go back and read it now.

AC Usage

• 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. Many electrical devices such as refrigerators require short bursts of extra power, in addition to the rated wattage listed by the device, to stop and start their motors. The surge wattage ability of the generator covers this extra power requirement.

Fuel Source Rated (Running) Wattage Surge (Peak) Wattage
Gasoline 9500 12000

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, find 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 find this wattage, you may calculate it by multiplying the Voltage requirement by the Amperage drawn: Watts = Volts x Amps. If these specifications 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 find 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.

Tool or Appliance Rated	(Running) Watts Additional Surge Watts
Electric water heater (40 gal) 4000 0
Hot plate 2500 0
Radial arm saw 2000 2000

CAUTION: The generator can only run at its surge wattage capacity for a very short time. Connect only electrical devices requiring a rated (running) wattage equal to or less than the rated wattage of the generator. Never connect devices requiring a rated wattage equal to the surge wattage of the generator.

NOTE: The above wattage figures are estimates only.

Try to check the wattage listed on your electrical devices before consulting this chart.

■ USING THE GENERATOR (CONTINUED)USING TH

Voltage Selector Switch

This generator features Power Boost Technology, which gives the user the ability to double the power in the generator for more heavy duty applications.

The voltage selector switches the dual 120V AC windings of the generator to produce "120V ONLY" or "120/240V". If a 240V appliance is connected to the 4-prong receptacle, the switch must be in the "120/240V" position. If only 120V appliances are being connected to the generator select the "120V ONLY" position to double the 120V amperage and automatically balance the load.

WARNING: Only change the voltage selector switch with the main AC circuit breaker OFF. The generator can be seriously damaged if the voltage selector switch is changed with the breaker ON.

Idle Control Usage

Idle control

The idle control feature lowers the RPM of the generator when there is no load to save gas and decrease engine noise.

When a load is applied, the engine will resume normal speed to provide usable power.

Turn on the idle control when using intermittent loads like power tools and air compressors.

The idle control feature is designed for gasoline only use.

WARNING: Power is unusable when idle control is engaged.

• DO NOT use the idle control function when using the generator for backup house power.
• Idle control function will cause massive fluctuations in voltage and hertz.
• Low amperage loads may not trigger the idle up function.

STOPPING THE GENERATOR

This section will cover the recommended shut off procedure for stopping the generator on various fuels.
