Note: Notes contain additional information important to a procedure and will be found within the regular text body of this manual.

OPERATING SAFETY

Before using the generator be sure you read and understand all of the instructions! This equipment was

designed for specific applications; DO NOT modify or use this equipment for any application other than

which it was designed for. Equipment operated improperly or by untrained personnel can be dangerous! Read the operating instructions and familiarize yourself with the location and proper use of all instruments and controls. Inexperienced operators should receive instruction from someone familiar with the equipment before being allowed to operate or set up the generator. The following points should be practiced at all times:

• The area immediately surrounding the generator should be dry, clean, and free of debris.

• NEVER start a unit in need of repair.

• Make certain the generator is securely fastened to a good earthen ground before use.

• NEVER operate unit on a combustible surface.

• NEVER operate the generator if any of the following conditions exist during operation:

1. Noticeable change in engine speed.

2. Loss of electrical output.

3. Equipment connected to the generator overheats.

4. Sparking occurs.

5. Engine misfires or there is excessive engine/generator vibration.

6. Protective covers are loose or missing.

7. If the ambient air temperature is above 120° F.

• Make sure slings, chains, hooks, ramps, jacks, and other types of lifting devices are attached securely and have enough weight-bearing capacity to lift or hold the equipment safely. Always remain aware of the position of other people around you when lifting the equipment.

ENGINE SAFETY

Internal combustion engines present special hazards during operation and fueling! Failure to follow the safety guidelines described below could result in severe injury or death. Read and follow all safety warnings described in the engine operator's manual. A copy of this manual was supplied with unit when it was shipped from the factory.

• DO NOT run engine indoors or in an area with poor ventilation. Diesel engine exhaust contains carbon

monoxide, a deadly, odorless and colorless gas which, if inhaled, can cause nausea, fainting or death. Only use this unit outside and away from windows, doors and ventillation equipment.

• DO NOT fill fuel tank near an open flame, while smoking, or while engine is running. DO NOT fill tank

in an enclosed area with poor ventilation.

• DO NOT operate with the fuel tank cap loose or missing.

• DO NOT touch or lean against hot exhaust pipes or engine cylinders.

• DO NOT clean air filter with gasoline or other types of low flash point solvents.

• DO NOT remove engine coolant cap while engine is hot.

• DO NOT operate the unit without a functional exhaust system. Prolonged exposure to sound levels

in excess of 85 DBA can cause permanent hearing loss. Wear hearing protection when working around a running engine.

• Keep hands, feet and loose clothing away from moving parts on the generator and engine.

• Keep area around exhaust pipes and air ducts free of debris to reduce the chance of an accidental fire.

• Batteries contain sulfuric acid which can cause severe injury or death. Sulfuric acid can cause eye damage, burn flesh or eat holes in clothing. Protective eye wear and clothing are necessary when working on or around the battery. Always disconnect the NEGATIVE (-) battery cable from the corresponding terminal before performing any service on the engine or other components..

ELECTRICAL SAFETY

The unit is powered by a generator driven by a diesel engine. While the engine is running, potentially lethal voltages are present at the 120V Ground Fault Circuit Interrupt (GFCI) outlets and the 240V twist lock outlets located on the control panel, and at the connection lugs and cam lock receptacles. Failure to follow the safety guidelines described below could result in severe injury or death.

• Only a qualified and licensed electrician should make connections to the generator.

• NEVER wash the unit with any high pressure hoses or power washers.

• NEVER start the unit under load. The circuit breakers must be in the “OFF” position when starting the

unit in MANUAL mode. The circuit breakers can be in the “ON” position only when started in the AUTO mode. A transfer switch must be used in the AUTO mode to deflect the load upon start up.

• ALWAYS disconnect the NEGATIVE (-) battery cable from the corresponding terminal before

performing any service on the engine, generator or any other components. Remove the NEGATIVE (-) battery cable from the corresponding terminal if the unit is to be stored or transported.

• ALWAYS use extreme caution when servicing this unit in damp conditions. Do not service the unit if

your skin or clothing is wet. Do not allow water to collect around the base of the unit.

• ALWAYS connect the unit to a good earthen ground before use. Follow any local, state or United

States National Electric Code (NEC) guidelines.

TOWING SAFETY

Towing a trailer requires care! Both the trailer and vehicle must be in good condition and securely fastened to each other to reduce the possibility of an accident. Also, some states require that large trailers be registered and licensed. Contact your local Department of Transportation office to check on license requirements for your particular unit.

• Check that the hitch and coupling on the towing vehicle are rated equal to, or greater than, the trailer's “gross vehicle weight rating” (GVWR).

• Check tires on trailer for tread wear, inflation, and condition.

• Inspect the hitch and coupling for wear or damage. NEVER tow trailer using defective parts!

• Make sure the trailer hitch and the coupling are compatible. Make sure the coupling is securely fastened to the vehicle.

• Connect safety chains in a crossing pattern under the tongue and attach the breakaway cable TO THE REAR BUMPER OF THE TOWING VEHICLE. Do not attach the cable to the trailer hitch.

• Make sure directional and brake lights on the trailer are connected and working properly.

• Check that lug nuts holding wheels are tight and that none are missing.

• Maximum recommended speed for highway towing is 45 mph. Recommended off-road towing speed is not to exceed 10 mph or less depending on terrain.

Before towing the trailer, check that the weight of the trailer is equal across all tires. On trailers with adjustable height hitches, adjust the angle of the trailer tongue to keep the trailer as level as possible. On units equipped with a tandem axle trailer, a large angle between the trailer and tow vehicle will cause more weight to be carried by one axle, which could cause premature wear on the tires and axles and cause potentially unsafe operating conditions.

The trailer is equipped with hydraulic surge brakes or electric surge brakes. Check the operation of the brakes by braking the vehicle at a slow speed before entering traffic. Both the trailer and the vehicle should brake smoothly. If the trailer seems to be pushing, check the level in the surge brake fluid reservoir.

When towing, maintain extra space between vehicles and avoid soft shoulders, curbs and sudden lane changes. If you have not pulled a trailer before, practice turning, stopping, and backing up in an area away from heavy traffic.

A film of grease on the coupler will extend coupler life and eliminate squeaking. Wipe the coupler clean and apply fresh grease each time the trailer is towed.

REPORTING TRAILER SAFETY DEFECTS

If you believe your trailer has a defect which could cause a crash or could cause injury or death, you should immediately inform the National Highway Traffic Safety Administration (NHTSA) in addition to notifying Magnum Products LLC.

If NHTSA receives similar complaints, it may open an investigation; and if it finds that a safety defect exists in a group of vehicles, it may order a recall and remedy campaign. However, NHTSA cannot become involved in individual problem between you, your dealer, or Magnum Products LLC.

To contact NHTSA, you may either call the Auto Safety Hotline toll-free at 1-888-327-4236 (TTY:1-800-424-9153), go to http://www.safercar.gov; or write to:

Administrator NHTSA 1200 New Jersey Avenue S.E. Washington, DC 20590

UNIT SERIAL NUMBER LOCATIONS

Refer to the locations illustrated below to find the unit ID tag, V.I.N. tag and trailer ID tag on your unit. Important information, such as the unit serial number, model number and Vehicle Identification Number (V.I.N.) for your trailer are found on these tags. Record the information from these tags, so it is available if the tags are lost or damaged. When ordering parts or requesting technical service information, you may be asked to specify this information.
