7. Maintenance
Perform maintenance and adjustment to keep the generator in the best operating
condition. Inspect or service as scheduled in the table below.
n Shut off generator before performing any maintenance. If the engine must be run,
make sure the area is well ventilated. The exhaust contains poisonous carbon
monoxide gas.
n Use genuine parts or their equivalent. The use of replacement parts that are not
of equivalent quality may damage the generator.
n When repairing or replacing the accessories of emission control system, make
sure to use the EPA standard accessories.
Emission control system
Emission source
Exhaust gas contains carbon monoxide, nitrous oxide (NOx), and hydrocarbons. It
is very important to control the emissions of NOX and hydrocarbons as they are
a major contributor to air pollution. Carbon monoxide is a poisonous gas. The
emission of fuel vapors is a source of pollution as well. The MMD PowerPro
generator engine utilizes a precise air-fuel ratio and emission control system to
reduce the emissions of carbon monoxide, NOX, hydrocarbons, and evaporative fuel
emissions.
Regulation
Your engine has been designed to meet current Environmental Protection Agency
(EPA) and the California Air Resources Board (CARB) clean air standards if so
equipped and designated. The regulations dictate that the manufacturer provides
operation and maintenance standards regarding the emission control system. Tune-
up specifications are provided in the specifications section and a description of the
emission control system may be found in an appendix to this manual. Adherence
to the following instructions will ensure your engine meets the emission control
standards.
Modification
Modification of the emission control system may lead to increased emissions.
Modification is defined as the following:
n
Disassemble or modify the function or parts of the intake, fuel or exhaust system.
n Modify or destroy the speed governing function of the generator.
Engine faults that may affect emission
Any of the following faults must be repaired immediately. Consult with your
authorized MMD Equipment service center for diagnosis and repair:
n Hard starting or shut down after starting
n Unstable idle speed
n Shut down or backfire after applying an electrical load
n Backfire or after fire.
n Black smoke and/or excessive fuel consumption
Replacement parts and accessories
The parts making up the emission control system applied to the engines have been
specifically approved and certified by the regulatory agencies. You can trust the
replacement parts supplied by MMD Equipment have been manufactured to the
same production standard as the original parts. The use of replacement parts or
accessories which are not designed by MMD Equipment may affect the engine
emission performance. The manufacturers of replacement parts and accessories
have the responsibility to guarantee that their replacement products will not
adversely affect emission performance.
Maintenance
Maintain the generator according to the maintenance schedule in this section.
More frequent maintenance should be performed when used in dusty areas, under
conditions of high load, temperature, and humidity.
Air Quality Index (only for California certified models)
CARB requires that an air quality index label be attached to every certified engine
showing the engine emission information for the emission duration period. The label
is provided for the user to compare the emission performance of different engines.
The lower the air index, the better the engine emission performance. The description
of durability is helpful for the user to learn the engine emission duration period and
the service life of emission control system. Refer to the warranty section of this
owner’s manual for more information.
