Owner’s Manual for Mobile Generator 5

Introduction and Safety

Operating Safety

Positioning the Unit

•

The area immediately surrounding the unit should

be dry, clean, and free of debris.

• If the unit is equipped with a frame grounding stud,

follow any local, state, and National Electrical Code

(NEC) guidelines when connecting.

Starting the Unit

•

DO NOT start a unit in need of repair.

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. 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.

Hitch and Coupling

•

Verify the hitch and coupling on the towing vehicle

are rated equal to, or greater than, the trailer's

Gross Vehicle Weight Rating (GVWR).

• Verify the trailer hitch and the coupling are

compatible. Verify the coupling is securely

fastened to the vehicle.

• DO NOT tow trailer using defective parts. Inspect

the hitch and coupling for wear or damage.

• Connect safety chains in a crossing pattern under

the tongue.

• Before towing the trailer, verify 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.

Safe Towing Techniques

•

Practice turning, stopping and backing up in an

area away from heavy traffic prior to transporting

the unit.

• Maximum recommended speed for highway towing

is 45 mph (72 km/h). Recommended off-road

towing speed is 10 mph (16 km/h) or less,

depending on terrain.

• When towing, maintain extra space between

vehicles and avoid soft shoulders, curbs and

sudden lane changes.

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 Generac

Mobile.

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

an individual problem between you, your GMASD, or

Generac Mobile.

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:

Introduction and Safety

Figure 1-3. Connection Panel Decals

Improper connection of generator to a building’s electrical system can allow electrical current from

the generator to backfeed into utility lines. This may result in electrocution of utility workers, fire or

explosion. Connections to a building’s electrical system must be made by a qualified electrician

and comply with all applicable laws and electrical codes.

Der unsachgemäße Anschluss eines Generators an das Stromnetz eines Gebäudes kann eine

Rückführung des elektrischen Stroms vom Generator in die Stromleitungen verursachen. Dies kann u.

U. zu tödlichem Stromschlag bei EVU-Mitarbeitern, Brand oder Explosion führen. Anschlüsse an das

Gebäudestromnetz müssen von einem Elektriker vorgenommen werden und es müssen dabei alle

einschlägigen Gesetze und elektrischen Vorschriften eingehalten werden.

La conexión inadecuada del generador al sistema eléctrico de un edificio puede hacer que la corriente

eléctrica del generador se retroalimente en las líneas de servicios públicos. Esto puede provocar la

electrocución de los trabajadores de servicios públicos, incendios o explosiones. Las conexiones al

sistema eléctrico de un edificio deben ser realizadas por un electricista calificado, y cumplir con todas

las leyes y todos los códigos de electricidad aplicables.

Le raccordement inadéquat de la génératrice au système électrique d’un immeuble peut permettre au

courant électrique produit par la génératrice de refouler dans le réseau public. Les ouvriers de la

compagnie d’électricité pourraient subir une électrocution, et un feu ou une explosion pourraient

survenir. Le raccordement au système électrique d’un immeuble doit être confié à un électricien

compétent et respecter l’ensemble des lois et codes en vigueur en matière d’électricité.

General Information

Unit ID and VIN Tag Locations

See Figure 2-2 to locate the unit ID tag (A) and vehicle

identification number (VIN) tag (B). Important information

such as the unit model number, serial number, VIN, and

tire loading information are listed on the tags. Record the

information from the tags in the event the tags are lost or

damaged. When ordering parts or requesting assistance,

information from the tags may be needed.

Figure 2-2. Unit ID and VIN Tag Locations

Altitude and Temperature Limitations

All units are subject to derating for altitude and

temperature as it relates to engine cooling capacity and

other capabilities. Derating reduces the available power

for operating tools and accessories connected to the

outlets. For the MDG250/175/150, the engine can

provide full prime power up to an altitude of 10,000 ft

(3,048 m). There will be a limitation in power output of 5%

if the unit is operated 1,000 ft (305 m) above the

maximum altitude indicated.

The maximum air temperature at which the unit can

provide full prime power is defined in the table below. If

the unit is operated beyond this limit at full power, the

coolant temperature will exceed the maximum allowable

limit of 235 °F (113 °C) and cause the engine to shut

down.

NOTE: For information specific to generator derating,

see the OEM generator manual included with the unit.
