OPERATING SAFETY
Before using the unit, 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 unit. The following points should be practiced at all times:
• The area immediately surrounding the unit should be dry, clean, and free of debris.
• Position and operate the unit on a firm, level surface.
• DO NOT start a unit in need of repair.
• If the unit is equipped with a frame grounding stud, follow any local, state, and National Electrical
Code (NEC) guidelines when connecting.
• DO NOT operate the unit on a combustible surface.
• DO NOT operate a unit while tired, distracted, or under the influence of drugs or alcohol.
• Keep all body parts, clothing and other loose items away from moving parts.
• 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.
• Shut the engine down if any of the following conditions exist during operation:
Safety
2 MMG130DI4/175DI4/205DI4 Operating Manual 33722 D
1. Noticeable change in engine speed.
2. Loss of electrical output.
3. Equipment connected to the unit 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 (49°C).
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 the unit when it was
shipped from the factory.
• DO NOT run engine indoors or in an area with poor ventilation unless exhaust hoses are used. Engine
exhaust contains carbon monoxide, a deadly, odorless and colorless gas which, if inhaled, can cause
nausea, fainting or death. Make sure engine exhaust cannot seep into closed rooms or ventilation
equipment.
• DO NOT touch or lean against hot exhaust pipes or engine components.
• DO NOT clean air filter with gasoline or other types of low flash point solvents.
• DO NOT operate the unit without a functional exhaust system.
• Prolonged exposure to sound levels in excess of 85 dB(A) can cause permanent hearing loss. Wear
hearing protection when working around a running engine.
• 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.
• DO NOT open the radiator cap or oil drain plug while the engine is running or before the engine has
cooled down. Pressurized coolant and hot engine oil can cause severe burns. Allow the unit to cool
completely before attempting any service work.
• Keep area around exhaust pipes and air ducts free of debris to reduce the chance of an accidental fire.
SERVICE SAFETY
All service work must be performed by qualified personnel who are familiar with the equipment. Only a
qualified electrician should troubleshoot or repair electrical problems occurring in this equipment. Fol-
low the safety guidelines described below to prevent hazardous situations which could result in severe
injury or death.
• NEVER wash the unit with high pressure hoses, power washers, or steam cleaners. Water may collect
in the unit, causing damage to electrical parts.
• 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.
• Replace all missing and hard to read decals. Decals provide important operating instructions and
warn of dangers and hazards.
• Before servicing the unit, verify the Control Power switch and circuit breakers are in the OFF (O)
position, and the negative (-) terminal on the battery is disconnected. DO NOT perform even routine
service (oil/filter changes, cleaning, etc.) unless all electrical components are shut down.
Safety
33722 D MMG130DI4/175DI4/205DI4 Operating Manual 3
• DO NOT start the unit under load. The circuit breakers must be in the OFF (O) position when starting
the unit in Manual mode. The circuit breakers can be in the ON (I) position only when started in the
Auto mode. A transfer switch must be used in the Auto mode to deflect the load upon startup.
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.
• Verify the hitch and coupling on the towing vehicle are rated equal to, or greater than, the trailer's
Gross Vehicle Weight Rating (GVWR).
• Check trailer tires for wear and proper inflation.
• DO NOT tow trailer using defective parts. Inspect the hitch and coupling for wear or damage.
• Verify the trailer hitch and the coupling are compatible. Make sure the coupling is securely fastened
to the vehicle.
• Verify directional and brake lights on the trailer are connected and working properly.
• Verify wheel lug nuts are present and tightened to the specified torque.
• Maximum recommended speed for highway towing is 45 mph (72 km/h). Recommended off-road
towing speed is 10 mph (16 km/h).
• When towing, maintain extra space between vehicles and avoid soft shoulders, curbs and sudden
lane changes. Practice turning, stopping and backing up in an area away from heavy traffic prior to
transporting the unit.
• Wipe the coupler clean and apply fresh grease each time the trailer is towed to eliminate squeaking.
• 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.
• Before towing the trailer, verify 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 or electric surge brakes. Verify proper 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, verify the level in the brake fluid reservoir, if equipped.
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 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 an individual
problem between you, your dealer, or Generac Mobile 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:

POWER ZONE™ CONTROLLER
The Power Zone™ controller is an auto start controller that monitors the unit and indicates operational status and
fault conditions. The controller can be programmed to automatically start or stop based on time schedule, fault
condition, or load demand.
The controller constantly monitors vital generator and engine functions for a number of preprogrammed alarm and
fault conditions. When a fault condition occurs, the engine can be shut down automatically and the LCD window will
show the fault that caused the shut down; to resume operation, the fault condition must be resolved.
This controller also records a history of unit performance which may be viewed at any time and will not be lost when
the controller is powered down.

The Home screen is the default screen of the controller and will display after the controller is powered up and the
General Information
33722 D MMG130DI4/175DI4/205DI4 Operating Manual 15
unit management software is loaded. It displays a live readout of the kW meter, percent of load used (gauge), selected
phase, volts and amps being produced by the generator, and the fuel level with time until empty. The controller will
automatically return to this screen from any other screen after a period of inactivity.
Figure 2-7. Home Screen
Engine Screen
The Engine screen displays the oil pressure, coolant temperature and battery voltage on three main gauges. Below
the gauges is an hour gauge displaying the total run time on the engine. At the bottom of the screen, this screen
also displays maintenance alarm status with the time remaining (black text) or the time past (red text) a scheduled
maintenance tasks, along with the description of the maintenance procedure and the action that will take place when
the timer trips the alarm.
Figure 2-8. Engine Screen
Note: If the measured value is outside the range of a gauge, the needle will not be displayed. The digital value below
the gauge will still show the measured value.
• Oil Press: Displays engine oil pressure. Current coolant temperature is displayed directly below the gauge
at all times. The gauge registers oil pressure between 0-100 psi (0-689 kPa). Normal operating pressure is
between 35-80 psi (241-552 kPa).
• Coolant Temp: Displays engine coolant temperature. Current coolant temperature is displayed directly
below the gauge at all times. The gauge displays coolant temperature between 150°-250°F (66°-121°C).
Normal operating temperature of the unit is between 180°-200°F (82°-93°C) with an average ambient air
temperature of 70°F (21°C).

• Battery: Displays the engine battery voltage. Current battery voltage is displayed directly below the gauge
at all times. The gauge displays battery voltage between 0-50V. A normal reading is 12-14V on 12 volt
systems and 24-26V on 24 volt systems (with the engine running).
Generator Screen
The Generator screen displays the average voltage frequency, volts and amps from the generator, as well as line-
to-line voltage, and individual line-to-neutral voltage, amperage and power (kW). This screen also displays the
generator winding configuration set by the voltage selector switch in the lower right corner.
Figure 2-9. Generator Screen
Note: When loading the generator, it is important to observe the amperage to determine the load balance on each
line of the generator. Minor load unbalances, usually ten percent or less, will not cause problems. Every effort should
be made to distribute the load equally between all lines.
• Freq: Displays the output frequency in Hertz (Hz). Normal operating frequency is 60 Hz.
• Volts: Displays the nominal voltage in Volts (V).
• Amps: Displays the AC output amperage produced by the generator in Amps (A).
Additional information can be found on the electric power table at the bottom-left side of the screen. This provides
an overview of all three lines and average voltage and amperage readouts.
Voltage Adjust Screen
The Voltage Adjust screen displays the line-to-neutral and line-to-line voltage averages. The operator can electron-
ically adjust the voltage within limits to prevent under-voltage or over-voltage conditions using the on-screen
instructions. This feature replaces a traditional potentiometer. See Fine Voltage Adjustment for more information.

CUSTOMER CONVENIENCE RECEPTACLES
The unit is equipped with five receptacles. The large
receptacles are 240/120VAC twist-lock receptacles
rated at 50A each. The smaller duplex receptacles
are 120VAC rated at 20A each with ground fault circuit
interrupt (GFCI) protection. These receptacles are not
routed through the main circuit breaker. Each recep-
tacle has its own circuit breaker, located directly above
or next to the receptacle. Each breaker is sized to the
maximum rating of the corresponding receptacle.
Power to the receptacles is
available any time the generator
is running, EVEN IF THE MAIN
CIRCUIT BREAKER IS OFF (O)
VERIFY ANY EQUIPMENT
CONNECTED TO THE
RECEPTACLES IS TURNED
OFF BEFORE TURNING THE
BREAKERS ON. Verify the
voltage selector switch is in the
proper position and that the
output voltage is correct for the
equipment that is connected to
the receptacles. Improper voltage
may cause equipment damage or
malfunction.
Note: When the voltage selector switch is in position for 480/277V 3Ø, voltage at the two GFCI receptacles is 139
volts and the voltage at the three twist-lock receptacles is 240/139 volts. Generac Mobile Products LLC does not
recommend using the receptacles in the 480V position. When the voltage selector switch is in position for 208/120V
3Ø, voltage at the three twist-lock receptacles and the two GFCI receptacles is 208/120 volts.

MAIN CIRCUIT BREAKER
The main circuit breaker is located on the main control panel. When the breaker is
OFF (O), power is interrupted between the connection lugs, the optional cam lock
receptacles, and the generator. Once the connections have been made to the
connection lugs or the optional cam lock receptacles, and the unit has been started
and allowed to reach normal operating temperature, the breaker may be switched ON
(I).
The main circuit breaker will be tripped, disconnecting power to the connection lugs
and the optional cam lock receptacles if any of the following items occur while the unit
is running:
1. Overload of the generator circuits to the connection lugs or the optional cam
lock receptacles (208/120V only).
2. The door covering the connection lugs or the optional cam lock receptacles is
opened.
3. If the emergency stop switch is activated.
4. LARGE MMG - If the door to the reconnect box (link board) is removed.
Make sure any problems that cause the main circuit breaker to trip are corrected before turning the switch ON (I).
The main circuit breaker interrupts power to the connection lugs and the optional cam lock
receptacles only. The control panel receptacles have power even if the main circuit breaker
is OFF (O). To disconnect power to these receptacles, use the individual circuit breakers
located near each receptacle.
EXHAUST FILTER CLEANING OPERATIONS
When enabled, the exhaust filter system goes through an automatic cleaning process known as regeneration. Under
normal circumstances, regeneration occurs without interruption of unit operation and with minimal operator involve-
ment. In the event there are conditions requiring the operation of the unit with the auto exhaust filter cleaning disabled,
the operator may be required to perform procedures to enable or disable the auto exhaust filter cleaning. The operator
may also be required to perform a manual regeneration. The following procedures describe how to perform these
functions.
WARNING
The area above and surrounding the exhaust system during an auto or manual exhaust
filter cleaning should be clear of any people and objects. Exhaust gases and compo-
nents can reach temperatures hot enough to ignite and melt common materials.
Note: Always park the unit in a safe location for elevated exhaust temperatures and check for adequate fuel level
before beginning the exhaust filter cleaning process. The cleaning cycle can take an extended period of time
(approximately 45 minutes). Cleaning is complete when the Regeneration indicator remains off.
TRANSFER SWITCH
The generator neutral is bonded to ground when shipped from the factory. The bonding
plate will need to be removed when the generator is used as a standby power supply.
Installation should be in compliance with the National Electrical Code (NEC), state and local
regulations.

Operation
32 MMG130DI4/175DI4/205DI4 Operating Manual 33722 D
When the generator is used as a standby power supply, it must be equipped with a transfer switch which isolates it
from the utility’s distribution system. A transfer switch is designed to transfer electrical loads from the normal power
source (utility) to the emergency power source (generator) when normal voltage falls below a prescribed level. The
transfer switch automatically returns the load back to the normal source when power is restored back to operating
levels.
DANGER
FAILURE TO ISOLATE THE GENERATOR FROM THE NORMAL POWER UTILITY CAN
CAUSE POTENTIALLY LETHAL VOLTAGE TO BACKFEED INTO THE UTILITY LINES.
THIS MAY RESULT IN INJURY OR ELECTROCUTION OF UTILITY WORKERS NEARBY.
MAKE SURE THE GENERATOR IS ISOLATED BY A TRANSFER SWITCH FROM ANY
LOCAL UTILITY LINES. THIS ALSO APPLIES IF THE GENERATOR IS BEING USED
AS A BACKUP TO SOME OTHER TYPE OF POWER SUPPLY.
Installation of a transfer switch or other type of remote starting device is the responsibility of the generator user.
Installation of such devices must be performed by following all directions supplied by the manufacturer of the switch.
If attaching the generator to a power supply normally serviced by a utility company, notify the utility company and
check state and local regulations. Familiarize yourself with all instructions and warning labels supplied with the switch.
Figure 3-10. Transfer Switch Operation
WARNING
ONLY a licensed electrician should perform wiring or related connections to the
generator. Installation should be in compliance with the National Electrical Code
(NEC), state and local regulations. Failure to follow these procedures could result in
property damage, personal injury or death. Before any connections are attempted,
verify the main circuit breaker and the Control Power switch are OFF (O) and that
the negative (-) battery cable has been disconnected from the engine starting battery.
When using the generator as a standby or substitute power supply, make sure the output
voltage and phase rotation of the generator match those of the local power utility. Improper
voltage or phase rotation may cause equipment damage or malfunction.

Section 7 - Options & Accessories
GENERATOR CAM LOCK CONNECTIONS OPTION
The unit may be equipped with cam lock connections, located below the receptacles. These receptacles provide
connection points for the attachment of external loads to the generator. A large decal on the inside of the connection
lug door details the proper connections for selected voltages.
WARNING
It is HIGHLY RECOMMENDED that only a trained and licensed electrician perform any
wiring and related connections to the generator. Installation should be in compliance
with the National Electrical Code (NEC), state and local regulations. Failure to follow
proper installation requirements may result in equipment or property damage, per-
sonal injury or death.
WARNING
Before any connections are made to the generator, make sure that the main circuit
breaker and the Control Power switch are OFF (O) and that the negative (-) battery
cable is disconnected. Potentially lethal voltages may be present at the generator
connection lugs.
DANGER
IMPROPER OR INCORRECT CONNECTIONS TO A BUILDING’S ELECTRICAL SYSTEM
CAN CAUSE POTENTIALLY LETHAL VOLTAGE TO BACKFEED INTO UTILITY LINES.
THIS MAY RESULT IN INJURY OR ELECTROCUTION TO UTILITY WORKERS NEARBY.
MAKE SURE THE GENERATOR IS SUPPLYING POWER TO AN ISOLATED OBJECT
OR BUILDING THAT IS NOT CONNECTED TO ANY UTILITY LINES.
Connections should be made by plugging power cables equipped with series 16 taper nose 400A/600V cam lock
plugs into the cam lock receptacles. Secure the connection by rotating the plug a 1/2 turn to the right. The lug door
is equipped with safety interlock switches that will trip the main circuit breaker and disable the voltage regulator,
dropping the generator output to residual voltage, if the door is opened while the unit is operating.
Figure 7-1. Cam Lock Connections
WARNING
DO NOT attempt to disable or modify the lug door safety switches. Equipment damage,
personal injury or death may result.
A ground connection is located on the far right of the cam lock panel. The unit MUST be connected to a good earthen
ground for proper operating safety. The generator neutral is bonded to ground when it is shipped from the factory.
The bonding plate will need to be removed when the generator is used as a standby power source. INSTALLATION
SHOULD BE IN COMPLIANCE WITH THE NATIONAL ELECTRICAL CODE (NEC),STATE AND LOCAL REGU-
LATIONS.

VISCOUS FAN CLUTCH OPTION
The viscous fan clutch option allows the engine cooling fan to engage at lower speeds and disengage at higher
speeds, increasing cooling system efficiency. The cooling fan will engage at full speed when the coolant temperature
rises. When the fan is operating at full speed, it will switch to a slower speed when the coolant temperature drops.
There will be an audible difference when the engine cooling fan switches speeds. Depending on unit model, the
temperature ranges vary between 170°F and 200°F (77°C and 93°C).
