Exhaust Control System - Generac Power Systems R100 Operator's Manual

VI. Exhaust Control System
With the engine running, carbon monoxide, nitrogen oxide and hydrocarbons are produced, and in certain conditions,
nitrogen oxide and hydrocarbon will react chemically with each other to make smoke while carbon monoxide is toxic, so
proper maintenance to control these dangers is very important.
To keep the exhaust of your engine within the standard exhaust emission, pay attention to the following:
1. Maintenance
Maintain the engine periodically in accordance with the maintenance schedule in the "Maintenance" section. The
maintenance schedule is based on normal use in normal conditions, if using under heavy load, dusty or wet circumstances or
in high temperature, service of the engine should be done more often.
2. Problems affecting exhaust emissions
•
Difficult starting or difficult stopping.
•
Unstable idling speed.
•
Exhausting of black smoke or consuming too much fuel.
•
Poor ignition, sparks or backfire.
•
Premature ignition.
If you are experiencing any of above problems, contact Generac Power Systems for help.
High Altitude Kit for EPAIII Engines
3000ft to 6000ft or 6000ft to 8000ft of elevation
At high altitude, the standard carburetor air-fuel mixture will be too rich. 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 differs from
that at which this engine was certified, for extended periods of time, may increase emissions.
The fuel system on this Engine or Equipment may be influenced by operation at higher altitudes. Proper operation can be
ensured by installing an altitude kit when required. See the table below to determine when an altitude kit is required.
Operating this engine without the proper altitude kit installed may increase the engine's emissions and decrease fuel
economy and performance. Kits may be obtained from Generac Power Systems, and should be installed by a qualified
individual.
Fuel Altitude Range*
Gasoline 0 – 3000 ft
3000 – 6000 ft
6000 – 8000 ft
Engine, Generator Set, Pressure Washer, Walk-Behind Lawnmower,
Compressor, Pump, Tiller etc.
*Elevation above sea level.
•
This high altitude jet is to be used at elevations above 3000 feet.
•
At elevations above 8000 feet, the engine may experience decreased performance, even with the high altitude kit.
To prevent serious injury from fire follow the kit procedures in a well-ventilated area away from ignition sources. If the engine is
hot from use, shut the engine off and wait for it to cool before proceeding.
The warranty may be void if necessary adjustments are not made for high altitude use by installing a high altitude kit.
If a carburetor is replaced, the proper high altitude kit jet will need to be installed into the replacement carburetor.
