OPERATING SAFETY
Before using the generator be sure you read and understand all instructions! 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 area immediately surrounding the generator should be clean, neat, and free of debris.
Position and operate generator tower on a firm, level surface.
NEVER start a unit in need of repair.
NEVER modify the generator or use it in a manner other than what it was designed for.
ALWAYS keep the generator doors closed when the engine is running. Do not start the generator if any
panels or guards are loose or missing.
ALWAYS connect the generator to a good earthen ground.
Move the generator main circuit breaker to the “OFF” position when servicing or troubleshooting the unit.
The output voltage of the generator can cause a fatal electric shock. Avoid contact with any alternating
current wiring when the engine is running. Make sure any extension cords or equipment connected to
the convenience outlets are in good working condition.
NEVER remove control box cover when the engine is running. Exposed live electrical terminals can
cause a fatal electrical shock.
Check your electrical requirements before installing or starting the generator.
Use a ground fault circuit interrupter (GFCI) in damp or highly conductive areas and construction sites
to prevent electrical shock.

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. Also 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 unless exhaust hoses are used.
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 touch or lean against hot exhaust pipes or engine cylinder.
DO NOT operate with the fuel tank cap loose or missing.
DO NOT remove engine coolant cap while engine is hot.
DO NOT clean air filter with gasoline or other types of low flash point solvents.
Keep area around exhaust pipes and air ducts free of debris to reduce the chance of an accidental fire.
Shut the engine down if any of the following conditions exist during operation:
A.
B.
C.
D.
E.

Noticeable change in engine speed.
Loss of electrical output.
Equipment connected to the generator overheats.
Sparking occurs.
Engine misfires or there is excessive engine/generator vibration.

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. DO NOT 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 brake away cable TO THE
REAR BUMPER OF THE TOWING VEHICLE.
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 m.p.h.. Recommended off-road towing speed
is not to exceed 10 m.p.h. or less depending on terrain.
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 or by fax at:
(202)-366-7882. Additional contact information can be found at: www.nhtsa.dot.gov.

GENERATOR OUTPUT CONNECTION LUGS
The generator is equipped with connection lugs behind a door below the controller face. The lugs provide
connection points for 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 ELECTRIC CODE
(NEC) as well as any local or state guidelines as required by law. Failure
to follow proper installation requirements may result in equipment or
property damage, personal 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 in the OFF “O”
position. Potentially lethal voltages may be present at the generator
connection lugs.

WARNING!
Improper or incorrect connections to a buildings electrical system can
cause potentially lethal voltages to backfeed onto utility lines. This
may result in injury or electrocution to utility workers nearby. Make
sure the generator is suppling power to an isolated object or building
that is not connected to any utility lines.
Connections to the lugs should be made by running the power cables through the circular plastic bushing
on the lower right side of the control box. DO NOT make any connections directly to the lug without routing
the cables through this bushing. The connection lug door is equipped with a safety interlock switch that will
automatically trip the main circuit breaker and disable the voltage regulator when the lug door is opened.
Use a 5/16” hex-wrench to tighten the cable connections.
A ground connection is located next to the connection lugs. The unit MUST HAVE this ground lug connected to a good earthen ground for proper operating safety. The ground connection SHOULD BE IN
COMPLIANCE WITH THE NATIONAL ELECTRIC CODE (NEC) AS WELL AS ANY STATE OR LOCAL
GUIDELINES OR CODES.

VOLTAGE SELECTOR SWITCH
The voltage selector switch is located on a panel attached to the generator behind the door located next to
the fuel tank filler. The selector switch is a three position switch that mechanically changes the connections between the generator output leads and the connection lugs on the main control panel. Voltage
ranges are selected by rotating the handle on the switch to the desired voltage.
WARNING!
NEVER CHANGE THE VOLTAGE SELECTOR SWITCH WHILE THE ENGINE
IS RUNNING! THIS WILL CAUSE SEVERE ARCING AND DAMAGE TO THE
SWITCH AND GENERATOR WINDINGS.

The voltage switch is equipped with a locking mechanism. Once the proper voltage has been selected,
push the red latch on the inside of the phase switch handle up and insert a padlock through the handle. By
locking the handle in place you will prevent unauthorized personnel from changing the switch settings.
NOTE: When the voltage selector switch is in position for 480/277V 3O, voltage at the two GFCI duplex
convenience outlets is 139 Volts and the voltage at the three twist-lock outlets is 240/139 Volts. When the
voltage selector switch is in position for 208/120V 3O, voltage at the three twist-lock outlets and the two
GFCI outlets is 208/120 volts.

AUXILIARY OUTLETS

AUXILIARY OUTLET
GROUNDING STUD

The control panel is equipped with six outlets for
running accessories or tools from the generator.
Power is supplied to the outlets any time the engine is running and the main circuit breaker and
the auxiliary outlet main circuit breaker are switched
on “I”.
Should the main breaker trip, or the auxiliary outlet main circuit breaker trip, remove some of the
load to the outlets before turning them back on.
Note: To ensure proper grounding, anytime the
generator is providing power to any equipment or
load panels that do not have a grounded plug a
ground wire must be added between the equipment and the grounding stud on the outlet panel per any
local, state or NEC codes and guidelines.

VOLTAGE REGULATION
System stability is the ability of the generator to respond to load transients. Decreasing stability makes the
generator less sluggish and faster to respond to load transients. If the stability of the regulator is decreased too much, the generator will tend to hunt under steady state conditions. To adjust the regulation,
see the included manual for the voltage regulator. The regulator is located behind the control panel on the
back of the generator box.

FINE VOLTAGE ADJUSTMENT
The output voltage can be fine adjusted after the generator is running by using the fine voltage adjustment
knob. The switch is located directly below the control power switch next to the control panel. This rheostat
will provide an increase (“+”) or a decrease (”-”) in the output voltage. To adjust the voltage, check the
output voltage on the LCD display. Turn the knob in the desired direction until the required voltage is shown
on the LCD display.

EMERGENCY STOP SWITCH
The generator is equipped with one emergency stop switch,
located on the side panel next to the auxiliary outlet panel.
The switch is clearly labeled with “EMERGENCY STOP” and
is red in color. The switch can be accessed and activated
with all doors closed and locked.
Activate the emergency stop switch by pushing the red button in until it locks down. This will trip the main circuit breaker
which will open the contact disconnecting the load to the connection lugs. This will also open the fuel pump solenoid, shutting down the engine and the Emergency Stop fault will be
displayed on the LCD. The switch will remain closed until it is
pulled out.
CAUTION! Use the EMERGENCY STOP only when the generator must be shut down immediately.
For any other shut down, follow the detailed shut down procedure.

MAIN CIRCUIT BREAKER
The main circuit breaker is located on the main control panel. When the breaker is in the off “O” position,
power is interrupted between the customer connection lugs and the generator. Once the connections
have been made to the connection lugs and the generator has been started and allowed to reach normal
operating temperature, the breaker may be switched to the on “I” position.
The main circuit breaker will be tripped, disconnecting power to the connection lugs, if any of the following
items occur while the unit is running:
1. Overload of the generator circuits to the connection lugs.
2. The door covering the customer connection lugs is opened.
3. If the emergency stop switch is activated.
Make sure that any problems that caused the main circuit breaker to trip are corrected before returning the
switch to the on “I” position.

WARNING!
THE MAIN CIRCUIT BREAKER INTERRUPTS POWER TO THE CUSTOMER
CONNECTION LUGS ONLY. THE CUSTOMER CONVENIENCE OUTLETS HAVE
POWER EVEN IF THE MAIN CIRCUIT BREAKER IS IN THE OFF “O” POSITION.
The auxiliary outlet main circuit breaker, located next to the main circuit breaker,
will disconnect all power to the auxiliary outlet panel.

REMOTE START TERMINAL BLOCK
The remote start terminal block is located under the lug box door just below the voltage selector switch. It
provides a connection for installation of a remote start switch which will allow the generator to be started by
a remote dry-contact closure switch.
Before pressing the “AUTO” button, verify that the contacts on any remote switch linked to the generator
are OPEN. If the contacts on a remote switch are closed, the generator will crank and start when AUTO is
selected on the controller. Attach the switch leads to the two unused terminals on the generators remote
start block. For additional information on starting the generator, see GENERATOR START UP section of
this manual.
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.
WARNING!
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 that the generator
is isolated by a transfer switch from any local utility lines. This also applies if
the generator is being used as a back up 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 generator to a power supply normally serviced by a utility company, notify
the utility company and check local and state regulations. Familiarize yourself with all instructions and
warning labels supplied with the switch.
WARNING!
It is strongly recommended that ONLY a licensed electrician perform any
wiring and any related connections to the generator. Installation should be in
compliance of the National Electric Code as well as any state or local codes or
regulations. Failure to follow these procedures could result in property
damage, personal injury or death. Before any connections are attempted,
make sure the main circuit breaker and the engine start switch are in the
OFF “O” position.
WARNING!
When using the generator as a stand by 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.

9. If the engine does not start after the first cranking attempt the engine will wait for 15 seconds to allow
the starter to cool and the LCD will show “Pause”. The engine will make two more attempts to start for
a total of three crank cycles.
10. Should the engine not start and run the LCD display will show “SD StartFail”. The starting sequence
may be repeated after the starter has had a minimum of two minutes to cool. The FAULT RESET
button needs to be pressed to clear the controller. The unit will start by pressing the ENGINE START
button.
Note: the engine controller may skip the pre-heat acquisition and engine pre-heat steps.
11. Once the engine starts it will slowly begin speeding up to a constant 1800 rpm. On units with isochronous engine governing, the engine may hunt or change speeds until operating temperature is reached.
After a few minutes of operation the engine will be warmed up and the LCD display will show engine
and generator operating parameters. Temperature will be shown as “0” until the engine temperature is
approximately 100 degrees Fahrenheit.

Once the generator is at normal operating temperature, check the generator for excessive noise, vibration
and coolant, oil or fuel leaks before applying any loads.
12. Check that the AC output voltage is correct. The output voltage can be fine adjusted by using the fine
voltage adjustment switch, described on page 16.
13. Check that the frequency (Hz) is correct. With no loads connected to the generator, the frequency
should read approximately 60-62 Hz, depending on the type of engine governing used.
14. If all wiring connections have been done correctly, switch the main circuit breaker to the on “I” position
and then add any loads attached to the convenience outlets by switching the respective circuit breaker
to the ON “I” position. You will notice a slight change in engine noise.

AUTO (REMOTE) STARTING OF THE GENERATOR
The AUTO button is used when the generator is started from a location other than the control panel by
using a remote start switch or transfer switch. AUTO (remote start) is the normal setting when the generator is being used as a standby power supply. Before putting the generator in the AUTO (remote start)
mode, review the PRE-START CHECK LIST and MANUAL STARTING OF THE GENERATOR sections
beginning on page 18. Also follow all safety warnings and information on isolating the generator with a
transfer switch if the unit is to be used as a standby power supply on pages 16 and 17. Then continue with
the steps described below:
1. Perform a manual start of the generator at least once to verify that the engine is operating correctly.
2. If a check of the remote start circuit is desired, press the “AUTO” button. The LCD display should highlight “AUT” in the upper left corner. Attach a jumper wire (minimum 16 gauge) equipped with two
alligator clips across the two unused terminals on the remote start terminal block. This applies a
ground to the EZ-1 to close the starting circuit. The engine should crank, start and run.
3. Remove the jumper wire from the remote start terminal block, the engine will stop. Connect any necessary wires from the remote start switch.
4. Confirm unit is in “AUTO” mode. The LCD display should have “AUT” hilighted in the upper left corner.
5. Close (set to ON/“I”) the main circuit breaker.
6. Secure the generator by closing and locking all access doors.
7. The generator is now ready for remote starting.

SHUTTING DOWN THE GENERATOR
Check with other personnel using power supplied by the generator and let them know that the power is
going to be turned off. Make sure the power shutdown will not create any hazards by accidentally turning
off equipment that needs to be kept on (pumps, compressors, lights, etc.).
1.
2.
3.
4.

Remove all loads from the generator by opening (turn to OFF/“O”) all circuit breakers.
Let the engine run for approximately five minutes to allow it to cool down.
Push the “ENGINE STOP” button.
Move the control power switch to the CONTROL OFF/“O” position.

EZ-1 CONTROLLER INFORMATION DISPLAYS AND FUNCTION
The MAGNUM EZ-1 controller constantly monitors vital generator and engine functions for a number of
operation, alarm and fault conditions. When a fault condition occurs, the engine will shut down automatically and the LCD display will show the fault that has caused the shut down. To resume operation, the fault
condition must be resolved. To reset the EZ-1 and resume operation, press the “FAULT RESET” button.
Operation, alarm and fault conditions and (displayed message) are described in the following table:

TROUBLESHOOTING AUTOMATIC SHUTDOWN CONDITIONS
LOW OIL PRESSURE SHUTDOWN
1. Check the level of the engine oil with the dipstick. The EZ-1 will shut the engine down when the oil
pressure is less than 20 psi. Add oil if required.
2. Visually inspect the engine for oil leaks.
3. If the oil level is good, restart the unit and verify the loss of oil pressure. Shut the engine down
immediately if the oil pressure value does not read 5 PSI within five (5) seconds.
4. Check the oil pressure sender on the engine block and the connecting wiring for damage. To
check for continuity between the sender and the EZ-1, remove the bolts at the top and center of the
control panel and open the panel like a door. Consult the DC wiring diagrams in this manual for the
proper path between the EZ-1 and the pressure sender.
5. If the oil level, pressure sender and wiring are good, the oil loss may be caused by engine failure.
Consult the engine OPERATION AND MAINTENANCE MANUAL for additional information on
excessive oil consumption.
HIGH COOLANT TEMPERATURE SHUTDOWN
1. Check the coolant level in the overflow jug.
2. Restart the engine and read the coolant temperature to verify High Coolant Temperature Shutdown. Stop the engine immediately if the coolant temperature is 230°F or more.
3. Allow the engine to cool! Add coolant to the overflow jug if it is low and then check the level of
coolant in the radiator. To access the radiator cap, you must remove a small panel on top of the
generator housing directly above the radiator. Add coolant until it is 3/4” below the filler neck. Re
place the radiator cap and access panel.
4. Check the radiator shroud and ducting for blockage and remove any foreign matter.
5. Inspect coolant hoses, engine block and water pump for visible leaks.
6. Check the tension of the serpentine drive belt for the water pump.
7. Check the coolant temperature sender on the engine block and the connecting wiring for damage.
To check for continuity between the sender and the EZ-1, remove the bolts around the control panel
and slowly drop panel down. Consult the DC wiring diagrams in this manual for the proper path
between the EZ-1 and the pressure sender.
8. If the sender and wiring are good and no other problems are found, restart the engine. Observe the
coolant temperature and shut the engine down immediately if it starts to overheat.
9. Reduce the load on the generator and restart the engine. Observe the coolant temperature and
shut the engine down immediately if it starts to overheat. Consult the engine OPERATION AND
MAINTENANCE MANUAL for additional information on engine overheating.

TROUBLESHOOTING AUTOMATIC SHUTDOWN CONDITIONS, CONTINUED
OVERCRANK SHUTDOWN
1. Check the fuel level in tank.
2. Check for proper operation of the fuel pump.
3. If the engine will not start, consult the engine OPERATION AND MAINTENANCE MANUAL for
additional information on troubleshooting starting problems.
OVERSPEED OR UNDERSPEED SHUTDOWN
1. Disconnect all loads and restart the generator. Read the frequency (Hz) on the LCD display.
With no loads on the generator, the frequency should read 60.0 Hz.
2. If the frequency is above or below 60.0 Hz, the engine speed will have to be adjusted. See the
engine manual for throttle adjustments on mechanical governed units and see the electronic
governor manual for electronically controlled units.

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

TRAILER WHEEL BEARINGS
The generator is equipped with a grease zerk fitting to allow lubrication of the wheel bearings without
the need to disassemble the axle hub. To lubricate the axle bearings, remove the small rubber plug on
the grease cap, attach a standard grease gun fitting to the grease zerk fitting and pump grease into the
fitting until new grease is visible around the nozzle of the grease gun. Use only a high quality grease
made specifically for lubrication of wheel bearings. Wipe any excess grease from the hub with a clean
cloth and replace the rubber plug when finished. The minimum recommended lubrication is every 12
months or 12,000 miles; more frequent lubrication may be required under extremely dusty or damp
operating conditions.

ENGINE AND GENERATOR MAINTENANCE
Poorly maintained equipment can become a safety hazard! In order for the equipment to operate safely
and properly over a long period of time, periodic maintenance and occasional repairs are necessary.
NEVER perform even routine service (oil/filter changes, cleaning, etc.) unless all electrical components
are shut down. When servicing this equipment always follow the instructions listed below.
Before servicing this machine, make sure the control power switch is turned to off “O”, the circuit breakers
are open (off, “O”), the emergency stop switch is activated (pushed in), and the negative (-) terminal on
battery is disconnected. Attach a “DO NOT START” sign to the control panel. This will notify everyone that
the unit is being serviced and will reduce the chance of someone inadvertently trying to start the unit. If the
unit is connected to a remote start or transfer switch, make sure the remote switch is also off and tagged.
Never wash the unit with a high pressure hose or with any kind of power washer. Never wash the engine
block or fuel tank with a power washer or steam cleaner. Water may enter the cabinet and collect in the
generator windings or other electrical parts, causing damage. If the unit is stored outside, check for water
inside the cabinet and generator and dry the unit thoroughly before starting.

RELOADING THE TIME TO SERVICE REMINDER
After scheduled service work has been completed, it is necessary to reload the Time To Service reminder
on the controller. The timer can be reset to count down from 250 hrs. Follow the programming instructions below:
1. Press PAGE SELECT
2. Press
to select > Engine protect
3. Press ENTER
Display reads > NextServTime
4. Press ENTER
5. Press

DAILY MAINTENANCE CHECKS
Check the engine oil level daily before starting engine. DO NOT start the generator if the oil level is below
the ADD mark on the dipstick. The normal operating level for the engine oil is anywhere in the crosshatch
pattern between the FULL and ADD markings. Add oil to the engine only if the level is below the ADD mark
on the bottom of the crosshatch pattern. DO NOT OVERFILL the crankcase. Consult the engine OPERATION AND MAINTENANCE MANUAL for the proper grade of oil, including special operating conditions such
as a change in season or climate.
Check the coolant level daily. The coolant is checked by visually inspecting the level in the coolant overflow
jug, located near the radiator. The normal operating level is anywhere between the FULL and ADD markings on the overflow jug, with the optimum level noted as “NORMAL RANGE”. Coolant may be added
directly to the overflow jug WHEN THE ENGINE IS STOPPED AND COMPLETELY COOL. Consult the
engine OPERATION AND MAINTENANCE MANUAL for coolant recommendations and proper mixture.
Check the condition of the air filter viewing the level of vacuum draw on the filter minder gauge. Replace
the air filter when the yellow center bar reaches the red section on the gauge (20 in. H20).
Use the schedule in the table below as a guide for regular maintenance intervals.
