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 nonammable 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 generator 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 generator load 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 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 engine 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.
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. DJ190FD-14100-3KJS
6,000 ft. - 8,000 ft. DJ190FD-14100-6KJS
MAINTENANCE AND CARE (CONTINUED)
Changing the Carburetor Main Jet
Unclip the cover and element
Unclip and remove the air lter cover, then remove the air
lter elements.
NOTE: Carburetor should be drained of all gasoline prior
to servicing.
1.
Unbolt element holder
Remove air lter nuts
Remove air lter bracket nut
Remove all 6 bolts of the element holder with an 8mm socket
wrench, then remove the element holder.
Remove the 2 front facing nuts connecting the air lter to the
carburetor.
Remove the nut attaching the bottom air lter bracket located
behind the air lter housing.
