Engine Oil Change; Maintenance Schedule; Air Filter - DeWalt DG2900 Instruction Manual

TAMPERING AND ALTERING
Tampering with or altering the emission control system may increase emissions beyond the
legal limit. Among those acts that constitute tampering are:
• removal or alteration of any part of the intake, fuel, or exhaust systems.
• altering or defeating the governor linkage or speed-adjusting mechanism to cause the engine to
operate outside its design parameters.
PROBLEMS THAT MAY AFFECT EMISSIONS
If you are aware of any of the following symptoms, have your engine inspected and repaired
by your authorized service center.
• Hard starting or stalling after starting
• Rough idle
• Misfiring or backfiring under load
• Afterburning (Backfiring)
• Black exhaust smoke or high fuel consumption
REPLACEMENT PARTS
The emission control systems on your Honda Engine were designed, built, and certified, to
conform with EPA and California Emission Regulations. We recommend the use of genuine
Honda parts whenever you have engine maintenance done. These original-design replacement
parts are manufactured to the same standards as the original parts, so you can be confident of
their performance. The use of replacement parts that are not of the original design and quality
may impair the effectiveness of your emissions control system.
A manufacturer of an aftermarket part assumes the responsibility that the part will not adversely
affect emissions performance. The manufacturer or rebuilder of the part must certify that use
of the part will not result in a failure of the engine to comply with emission regulations.

Wash your hands with soap and water after handling used oil.
Please dispose of used motor oil and containers in a manner that will not harm the natural
environment. We suggest you take it in a sealed container to your local service station or
recycling center for reclamation. Do not throw it in the trash, pour it on the ground or down the
drain.
NOTE: Never operate the generator without oil cap tightly secured. Failure to do so could cause
oil to spill out of the engine.

AIR FILTER

A dirty air cleaner will restrict airflow to the carburetor. To prevent carburetor malfunction, service
the air filter regularly. Service more frequently when operating the generator in extremely dusty
areas.
WARNING!: Using gasoline or flammable solvent to clean the filter element can cause a
fire or explosion. Use only soapy water or nonflammable solvent.
