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 DR Power Equipment for help.
