Maintenance; Troubleshooting - DeWalt DG2900 Instruction Manual

NOTE: When the carburetor has been modified for high altitude operation, the air-fuel mixture
will be too lean for low altitude use. If the generator is used at low altitudes after a carburetor
modification, the carburetor may cause the engine to overheat and result in serious engine
damage. For use at low altitudes, have your authorized service center return the carburetor to
original factory specifications.
High and Low Temperature Operation
Air temperature affects generator output. Output drops 1% for each 10˚F temperature rise
above 60˚ F. Very low temperature may cause the engine to be hard to start.
Charging Portable Power Tool Batteries
WARNING! Condenser type chargers should not be used with portable generators. Irregular
generator power could cause a condenser type charger to fail. D
condenser type chargers in the past. (DW9104 and DW9106). If you have any questions
regarding the use of a D WALT Charger with a generator, please call 1-800-4D

NOTE: Other battery charger manufacturers have and still produce condenser type chargers.
Please contact manufacturer to see if it is safe to use chargers with portable generators.

Troubleshooting

If the engine does not start
1. Check the fuel tank for sufficient fuel. Refill with fresh gasoline if necessary.
2. Check the engine oil. Fill to the upper limit with fresh oil.
3. Ensure that the fuel petcock is open. The fuel petcock is open when the lever is
perpendicular to the ground (straight up and down as in figure 15).
4. Check that the spark plug cap is securely attached to the spark plug.
5. Inspect the air filter. Clean or replace it if necessary.
6. Disconnect all electrical loads from the generator, and turn the engine switch on.
7. Follow the starting procedures in this manual on page 6.
If the engine still does not start
1. Pull the starter handle 5-6 times (for recoil start models only).
2. Remove and inspect the spark plug.
If the spark plug is dry:
1. Ensure that there is fresh fuel in the tank and that the fuel petcock is open.
2. Reinstall the spark plug and spark plug cap.
3. Try to start the engine again by following the starting procedures in this manual on page 6.
4. If the engine fails to start, take the generator to an authorized D
center.
If the spark plug is wet.
1. Clean, gap, or replace the spark plug.
2. Reinstall the spark plug and spark plug cap.
3. Try to start the engine again by following the starting procedures in this manual on page 6.
4. If the engine fails to start, take the generator to an authorized D
center.
If there is no power to the receptacles
1. Turn the circuit breaker switches off and disconnect all electrical loads from the generator.
2. Turn the circuit breakers on and test the GFCI's by following the procedures in this manual
on page 1.
3. Place the voltage selector to the 120 Volt only positions (unless you are using a tool that
requires 240 Volts).
4. Turn the idle control switch off.
5. Turn the circuit breaker(s) off and reconnect the electrical loads. Be sure that the plugs are
securely connected to the receptacles.
6. Turn the circuit breaker(s) on.

MAINTENANCE

Importance of Maintenance
Good maintenance is essential for safe, economical, and trouble-free operation. It will also help
reduce air pollution.
WARNING! Improper maintenance or failure to correct a problem before operation can
cause malfunction, serious injury, or death. Always follow the inspection and maintenance
recommendation and schedules in this user's manual.

generator. If you are not comfortable with any maintenance procedure, have the generator
serviced by a professional technician.
Maintenance, replacement, or repair of the emission control devices and system may be
performed by any engine repair establishment or individual, using parts that are "certified" to
EPA standards.
Maintenance Safety
WARNING! Always follow the procedures and precautions in the owner's manual. Failure
to properly follow maintenance instructions and precautions can lead to serious injury or
death.
SAFETY PRECAUTIONS
CAUTION: Make sure that the engine is off before you begin any maintenance or repairs.
This will eliminate several potential hazards, including:
• carbon monoxide poisoning from engine exhaust. Be sure there is adequate ventilation
whenever you operate the engine.
• burns from hot parts. Let the engine and exhaust system cool before you touch it to prevent
burns.
• injury from moving parts. Wear appropriate clothing, tie back long hair, and stay alert around
the generator to prevent injury from moving parts.
Read the instructions before you begin, and make sure you have the tools and skills required.
Your authorized service center knows your generator best and is fully equipped to do
maintainance and repair. To ensure the best quality and reliability, use only new genuine parts
or their equivalents for repair or replacement.

CAUTION: To reduce the possibility of fire or explosion, be careful when working around
gasoline. Use only a nonflammable solvent, not gasoline, to clean parts. Keep tobacco
products, sparks, and flames away from all fuel related parts.
Emission Control System
SOURCE OF EMISSIONS
The combustion process produces carbon monoxide, oxides of nitrogen, and hydrocarbons.
WALT or Honda service
E Control of hydrocarbons and oxides of nitrogen is very important because, under certain
conditions, they react to form photochemical smog when subjected to sunlight. Carbon
monoxide does not react in the same way, but it is toxic.
A Honda engine powers your D
other systems to reduce the emissions of carbon monoxide, oxides of nitrogen, and
hydrocarbons.
THE U.S. AND CALIFORNIA CLEAN AIR ACTS
EPA and California regulations require all manufacturers to furnish written instructions
describing the operation and maintenance of emissions control systems.
The following instructions and procedures must be followed in order to keep the emissions from
your Honda Engine within the emissions standards.
