3.0 Servicing
The maintenance schedule ( Section 3.2, Maintenance Schedule) maintains the generator in peak operating
condition. The oil should be changed between the first 4 to 6 hours of operation to remove any manufacturing
debris or contamination.
The exhaust contains poisonous carbon monoxide gas. Shut off the engine before performing
any maintenance. If you must run the engine, make sure the area is well ventilated.
WARNING! FUMES HAZARD
Use genuine Alpha parts. The use of replacement parts not of equivalent quality may damage the generator.
When repairing or replacing components of the emission control system, only use parts known to comply with EPA
standards.
CAUTION!
3.1 Emission Control System
Emission Source
Exhaust gas contains carbon monoxide, nitrogen oxides (NOx), and hydrocarbons. Controlling the
emissions of NOx and hydrocarbons is very important, as they are a major contributor to air pollution.
Carbon monoxide is a poisonous gas. The emission of fuel vapors is also a source of pollution. The Alpha
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
This 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 Section 6.0, Specifications. Adherence to the following instructions will help ensure the
engine meets the emission control standards.
Modification
Modification of the emission control system may lead to increased emissions and will void the warranty
statement. 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
Any of the following faults must be repaired immediately. Consult with Alpha technical support for diagnosis
and repair. The following engine faults may affect emission:
• Hard starting or shut down after starting.
• Unstable idle speed.
• Shut down or backfire after applying an electrical load.
• Backfire.
• Black smoke and/or excessive fuel consumption.
