Maintenance
The purpose of the maintenance and adjustment schedule is to keep the generator in the best operating condition.
Inspect or service as scheduled in the table below.
There are no special operating instructions for the break in period for the engine, but the oil should be changed after the
first 4 to 6 hours of operation to remove any manufacturing debris or contamination.
•
Shut off the engine before performing any maintenance. If the engine must be run, make sure the
area is well ventilated. The exhaust contains poisonous carbon monoxide gas.
•
Use genuine POWERHOUSE
®
parts or the equivalent. The use of replacement parts which are not of
equivalent quality may damage the generator.
•
When repairing or replacing the components of the emission control system, make sure to use the
EPA standard components.
7.1.
Emission Control System
Emission source
Exhaust gas contains carbon monoxide, nitrogen oxides (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 POWERHOUSE
®
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. 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 the 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:
•
Disassembling or modifying the function or parts of the intake, fuel or exhaust system.
• Modifying or destroying 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 POWERHOUSE
®
service center for
diagnosis and repair:
•
Hard starting or shut down after starting.
• Unstable idle speed.
•
Shut down or backfire after applying an electrical load.
•
Backfire or after fire.
•
Black smoke and/or excessive fuel consumption.
Replacement parts and accessories
The parts making up the emission control system applied to POWERHOUSE
®
engine have been specifically approved
and certified by the regulatory agencies. You can trust that the replacement parts supplied by POWERHOUSE
®
have been
manufactured to the same production standard as the original parts. The use of replacement parts or accessories which
are not designed by POWERHOUSE
®
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. Service items more frequently when used in
dusty areas, or under conditions of high load, temperature, and humidity.
