Critical Safety Rules for Generator Operation

Risk of Asphyxiation: Carbon Monoxide Poisoning

NEVER operate this generator within an enclosed area. Generator exhaust contains carbon monoxide (CO), a colourless and odourless poison that can kill you in minutes. This includes garages, even with doors and windows open. Always use the generator OUTSIDE and far away from windows, doors, vents, and any openings that could allow CO to enter occupied spaces. Ensure adequate ventilation to prevent the accumulation of deadly exhaust gases. Using a fan or opening a door is NOT sufficient ventilation. Point the muffler exhaust away from people and occupied buildings.

Risk of Electrocution or Shock

Generators produce electrical current. Improper use can lead to electrocution, serious injury, or death. Only operate, service, or repair this generator if you are fully qualified. This generator is designed for DRY CONDITIONS and OUTDOOR AREAS ONLY. Never operate in rain, snow, sleet, or wet conditions. If connecting to a building's electrical system, ensure positive isolation between the generator output and utility power using a properly installed transfer switch. Failure to do so can cause generator damage and poses a risk of injury or death to utility workers due to backfeeding. Always turn off the main switch before connecting a generator to a residence's electrical system. For permanent connections, a double-throw transfer switch installed by a qualified electrician is mandatory. Always follow local codes and regulations, including NFPA 70 (National Electrical Code) and NFPA 37 (Standard for Installation and Use of Stationary Combustible Engines).

Risk of Fire or Explosion

Maintain at least 6 feet of clearance on all sides of the generator during operation to prevent fires. Gasoline is highly flammable, and its vapours are explosive. NEVER refill a hot generator with fuel or refill while it is running. Allow the generator to cool before refuelling. Do not store the generator in locations where gasoline fumes could contact sparks or open flames. Periodically inspect the spark arrestor, which is legally required in some areas (e.g., California) and minimizes the risk of fire from exhaust sparks. Do not operate the generator if the ambient temperature exceeds 104°F (40°C).

Risk of Bodily Injury

Keep hands, body parts, hair, and clothing well away from all moving parts, especially the exhaust system, which remains hot even after shutdown. DO NOT TAMPER WITH THE ENGINE-GOVERNED SPEED. Operating the generator above its rated speed (3600 RPM) can cause serious injury due to rotational stress. Operating below the nominal speed can lead to low voltage output and damage. When lifting or transporting the generator, use appropriate lifting equipment and methods, ensuring all fasteners are tight.

Battery Safety (Electric Start Models)

Storage batteries produce explosive hydrogen gas. Keep sparks, flames, and smoking materials away. Wear eye protection, rubber aprons, and gloves when working near batteries. Battery fluid is caustic sulfuric acid. Always disconnect the negative (-) battery cable FIRST, then the positive (+) battery cable when performing service. When installing a new battery, connect the positive (+) terminal FIRST, then the negative (-) terminal.

Environmental Protection

Regularly inspect the exhaust system for leaks to maintain proper functioning and reduce noise. Direct the generator's louder sides into open spaces to avoid sound reverberation. Never drain or dispose of engine oil into the ground or domestic wastewater systems.

Table 1: Generator Contents

Installing Accessory Kits

Minor assembly is required. You will need various box wrenches (10mm, 12mm, 13mm, and 8mm for 8000W models). Follow the specific instructions for installing the wheel kit and handle assembly, paying close attention to the correct bolts, washers, and nuts for each model (DXGNR6500 and DXGNR8000).

Battery Replacement/Connection

Ensure the battery is properly connected. If the battery is low, use the included 12V charger. Remember, running the generator does not charge the battery. Always disconnect the negative cable first, then the positive, before servicing. When reconnecting, attach the positive cable first, then the negative.

Emissions Information

This generator complies with exhaust and evaporative emission standards set by the EPA and California Air Resources Board (CARB). Refer to the emissions compliance decal on the engine for specific standards and warranty information. The exhaust contains chemicals known to cause cancer, birth defects, or reproductive harm.

Operating Your DeWalt Generator

Know Your Generator

Familiarise yourself with all components, including the various outlets (120 Volt AC, 20 Amp GFCI Duplex Outlets, 120/240 Volt AC, 30 Amp Locking Receptacle), circuit breakers, oil drain, air filter, choke lever, fuel tank, grounding lug, start/run/stop switch, muffler, handle, gas cap, oil fill, recoil starter, fuel shut-off valve, and CO Protect system (if equipped). The wattage meter and runtime meter on the 8000W model provide valuable operational data.

Hour Meter and Maintenance Alerts

The hour meter tracks operation for scheduled maintenance. It will display "CHG OIL" every 100 hours and "SVC" every 200 hours, with flashing alerts preceding these intervals. The hourglass icon flashes when the engine is running, indicating the meter is recording hours.

Connection Plugs Explained

120 VAC, 20 Amp GFCI Duplex Receptacle: Powers 120V AC loads up to 2400 watts (20 Amps). Protected by a 20 Amp circuit breaker. Use high-quality, 3-wire grounded cord sets rated for 125 Volts at 20 Amps or greater.

120/240 VAC, 30 Amp Receptacle: Use a NEMA L14-30 plug. Powers 120V loads up to 3600 watts (30 Amps) or 240V loads up to 7200 watts (30 Amps). Protected by a 30 Amp double-pole circuit breaker. Cord sets should be rated for 250 Volts AC at 30 Amps or greater.

Idle Control Switch

This switch automatically reduces engine speed when no load is present, saving fuel. It can also be turned off to maintain higher RPM at all times.

CO PROTECT System

This system monitors for dangerous CO levels and automatically shuts off the engine if they accumulate. A blinking red light indicates a CO hazard; a blinking yellow light indicates a system fault. CO PROTECT is not a substitute for an indoor carbon monoxide alarm. If the system shuts off due to CO, relocate the generator to a safe, open outdoor area. If a fault is indicated, contact a service center.

How to Use the Generator

Always operate on level ground. Disconnect all electrical loads before starting or stopping the engine. Follow the starting procedure for either pull-start or electric-start models, ensuring correct choke and fuel shut-off valve usage.

Generator Shut Down

Turn off all loads and unplug them from the receptacles. Let the engine run at no-load for a few minutes to cool down before moving the Run/Stop switch to "Stop". Close the fuel valve.

Low Oil Level Shutdown

The engine is equipped with a sensor that automatically shuts down the engine if the oil level drops too low. Ensure the oil is at the correct level before attempting to restart.

Charging the Battery

Running the generator does NOT charge the battery. Use the provided 12V charger for charging. Charge in a dry location, plugging into the generator's input jack and a 120V AC wall outlet. Unplug the charger when the generator is in use. Do not charge for more than 48 hours continuously.

Preventive Maintenance Schedule

Regular maintenance is key to performance and longevity. Follow these intervals:

Engine Maintenance Details

Engine Oil Recommendations

Use oil meeting API Service Class SJ, SL, or better. Viscosity grade depends on temperature: SAE 30 above 40°F, 10W-30 between 10°F and 40°F, and synthetic 5W-30 for all temperatures. Use petroleum-based oil for the initial 30-hour break-in period.

Changing Engine Oil

Change oil while the engine is warm. Disconnect the spark plug wire. Drain oil through the drain plug into a suitable container. Replace the drain plug, refill with the correct type and amount of oil, and reinstall the oil fill cap.

Air Filter

A dirty air filter impedes performance. Clean or replace as needed, more frequently in dusty conditions. Wash the filter in soapy water, squeeze dry, and clean the cover before reinstallation.

Servicing Spark Plug

Clean the area around the spark plug before removal. Inspect the electrode gap and reset to 0.70-0.80 mm (0.028-0.031 in). Replace the plug if electrodes are damaged or the porcelain is cracked. Tighten securely.

Valve Clearance

Check valve clearance after the first 50 hours of operation. Intake: 0.09 ± 0.02mm (cold). Exhaust: 0.14 ± 0.02mm (cold). Adjust if necessary or consult a service center.

Inspecting Spark Arrester Screen

Check the screen for damage. Clean with solvent or replace if torn or perforated. Ensure the spark arrestor cone and screen are securely fastened.

Storage Procedures

General Storage

Start and run the generator for 30 minutes every 30 days. If storing for longer periods, prepare the unit as follows: Allow the generator to cool completely before covering. Use a moisture-resistant cover and store in a clean, dry area away from heat and ignition sources. Do not store fuel from one season to another without proper treatment.

Preparing Fuel System/Engine for Storage

Fuel stored for over 30 days can degrade. Use a fuel stabilizer and run the engine for 10-15 minutes to circulate it. If not using stabilizer, drain the fuel tank and run the engine until it stops from fuel starvation. Change the engine oil before storage. Remove the spark plug, pour 5-10 cc of clean oil into the cylinder, and pull the recoil starter a few times to distribute the oil. Reinstall the spark plug and gently pull the recoil until resistance is felt to close the valves.
