MAINTENANCE AND CARE
8
Proper routine maintenance of your generator is essential for safe, economical, and trouble-free
operation. It will also help reduce air pollution.
Maintenance Schedule
Remember that this schedule is based on the assumption that your machine will be used for its
designed purpose. Sustained high-load, high-temperature operation, or use in unusually wet or
dusty conditions, will require more frequent service.

WARNING: Improper maintenance, or failure to correct a problem before operation, can
cause a malfunction in which you can be seriously injured or killed. Always follow the
inspection, maintenance recommendations, and schedules in this instruction manual.
●Make sure the engine is o before you begin any maintenance or repairs.
●Let the engine and exhaust system cool before touching.
●To reduce the possibility of re or explosion, be careful when working around
gasoline. Use only a nonammable solvent, not gasoline, to clean parts. Keep
cigarettes, sparks, and ames away from all fuel-related parts.

9
Break-In Period
As the best practice for any new combustion motor it’s recommended to perform the break
in procedure as follows:
●Run the engine for the rst 6-8 hours on conventional oil, then change the oil. After
the break-in period synthetic oil may be used.
●During the break in period of the rst 6-8 hours keep the engine speed under 50% for
optimal results.
●Check and clean the air lter if necessary after the break-in period.
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 diers from that at which this engine was certied, for extended periods of
time, may increase emissions. High altitude performance can be improved by specic modications to
the carburetor. If you always operate your engine at altitudes above 3,000 feet (900 meters), have a dealer
perform this carburetor modication. This engine, when operated at high altitude with the carburetor
modications for high altitude use, will meet each emission standard throughout its useful life. Even with
carburetor modication, engine horsepower will decrease by about 3.5% for each 1,000-foot (300-meter)
increase in altitude. The eect of altitude on horsepower will be greater than this if no carburetor
modication is made.
When the carburetor has been modied 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 modied carburetor may cause
the engine to overheat and result in serious engine damage.
Note: Jet kits available for purchase upon request, please contact us at 844-DUROMAX to set up your
parts order.
Altitude Range Jet Kit Part Number
3,000 ft. - 6,000 ft. 93140-Z2F0110
6,000 ft. - 8,000 ft. 93141-Z2F0110

Checking 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 sucient 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 “Generator Setup” section).
e. The oil will be visible in the oil ll spout when full.
f. Be sure to replace the cap when nished checking
oil.
Model Number XP13000EH
Engine Oil Capacity 40.5 . oz (1.2 L)

15
Changing the Oil
Remove drain plug
Using a 12 mm hex wrench, unscrew the oil drain plug, which
is located on the crankcase underneath the oil ller/dipstick
cap.
Allow all the oil to drain from the generator.
1.
Drain oil
Drain oil into an approved oil disposal container. Contact
your local auto parts store for information on oil disposal.
2.
Replace drain plug
Replace the oil drain plug and tighten with a 12 mm hex
wrench.
3.
CAUTION: Worn out or dirty oil does not cool the
generator properly and can lead to catastrophic
engine damage.
In addition to regular oil changes, it is necessary to drain the
oil from the crankcase if it has become contaminated with
water or dirt.

MAINTENANCE AND CARE (CONTINUED)
16
Routine maintenance of the air cleaner helps maintain proper
airow to the carburetor. Check that the air cleaner is free of
excessive dirt after every use.
CAUTION: Improper maintenance may cause
less air to enter the engine or dirty air to enter
the engine causing overheating and engine
wear.
Cleaning the Air Filter
Remove the lter cover screw
Remove lter cover
Clean out lter casing
Remove the lter cover screw.
Remove the lter cover and the sponge-like element from
the casing.
Wipe the dirt from inside the empty air cleaner casing.

replace the cover.
7.
Wash cleaner element
Wash the sponge-like elements in household dish detergent
and warm water.
4.
Dry cleaner element
Pat dry on a dry cloth and allow the elements to dry completely.
5.
6. Addengine oilto elements
Soak the dry elements in a small amount of engine oil. Ring
out any excess oil.

MAINTENANCE AND CARE (CONTINUED)

The spark plug is important for proper engine operation.
A good spark plug should be intact, free of deposits, and
properly gapped.
Spark Plug Maintenance
Remove spark plug cap
Remove spark plug
Inspect spark plug
Pull on the spark plug cap to remove it.
Unscrew the spark plug from the generator using the spark
plug wrench included with this product.
Visually inspect the spark plug. If it is cracked or chipped,
discard and replace it with a new spark plug. We recommend
using an F6RTC spark plug such as NGK BPR6ES.

CAUTION: Improper maintenance may cause reduced fuel economy, misres,
trouble starting, or damage to the spark plug threads.

Measure plug gap
Measure the plug gap with a gauge. The gap should be 0.7-0.8
mm (0.028-0.031 in).
4.
Clean and re-gap
If you are re-using the spark plug, use a wire brush to clean
any dirt from around the spark plug base and then re-gap the
spark plug.

Emptying the Gas Tank
Shut fuel valve OFF
Remove fuel lter cup
Empty fuel lter cup
Turn the fuel valve to the “OFF” position.
Remove the fuel lter cup (see “Removing the Fuel Filter Cup”
earlier in this section).
Empty the fuel lter cup of any fuel.

CAUTION: Do not store fuel from one season
to another. Gasoline sold at the pump today
contains additives such as ethanol that even
when stored properly may damage the fuel
system components.
If you have been using gasoline in your generator, before
storing your generator for extended periods of time you
should drain your generator fuel tank of gasoline.
