6 Operator’s Manual
CARBON MONOXIDE - POISONOUS GAS
Use generator outdoors, away from open windows, vents, or doors.
Generator exhaust contains carbon monoxide - a poisonous gas
that can kill you. You CAN NOT smell or see this gas.
Never use a generator in enclosed or partially-enclosed spaces.
Generators can produce high levels of carbon monoxide very
quickly. When you use a portable generator, remember that you
cannot smell or see carbon monoxide. Even if you can’t smell ex-
haust fumes, you may still be exposed to carbon monoxide.
If you start to feel sick, dizzy, or weak while using a generator, get
to fresh air RIGHT AWAY. DO NOT DELAY. The carbon monoxide
from generators can rapidly lead to full incapacitation and death.
If you experience serious symptoms, get medical attention immedi-
ately. Inform medical staff that carbon monoxide poisoning is sus-
pected. If you experienced symptoms while indoors, have someone
call the re department to determine when it is safe to re-enter the
building.
Never operate the generator in an explosive atmosphere, near com-
bustible materials or where ventilation is not sufcient to carry away
exhaust fumes. Exhaust fumes can cause serious injury or death.
NEVER use a generator indoors, including in homes, garages,
basements, crawl spaces, and other enclosed or partially-enclosed
areas, even with ventilation. Opening doors and windows or using
fans will not prevent carbon monoxide build-up in the home.
Follow the instructions that come with your generator. Locate the
unit outdoors and away from doors, windows, and vents that could
allow the carbon monoxide gas to come indoors.
ONLY run generator outdoors and away from air intakes.
NEVER run generator inside homes, garages, sheds, or other semi-
enclosed spaces. These spaces can trap poisonous gases EVEN
IF you run a fan or open doors and windows.
If you start to feel sick, dizzy, or weak while using the generator,
shut if off and get fresh air RIGHT AWAY. See a doctor. You may
have carbon monoxide poisoning.
Install battery-operated carbon monoxide alarms or plug-in carbon
monoxide alarms with battery back-up in your home, according to
the manufacturer’s installation instructions. The carbon monoxide
alarms should be certied to the requirements of the latest safety
standards for carbon monoxide alarms. (UL 2034, IAS 6-96, or CSA
6.19.01).
Test your carbon monoxide alarm frequently and replace dead bat-
teries.

Operator’s Manual 7
SAFETY WARNING WHEN REFUELING
Gasoline is extremely ammable and its vapors can explode if ignited.
Observe all safety regulations for the safe handling of fuel. Handle fuel in
safety containers. If the container does not have a spout, use a funnel.
Do not overll the fuel tank, leave room for the fuel to expand.
Do not rell fuel tank while the engine is running. Before refueling the
generator, turn it off and let it cool down. Gasoline spilled on hot engine
parts could ignite.
Fill the tank only on an area of bare ground. While fueling the tank, keep
heat, sparks and open ame away. Carefully clean up any spilled fuel
before starting engine.
Always ll fuel tank in an area with plenty of ventilation to avoid inhaling
dangerous fumes.
NEVER store fuel for your generator in the home. Gasoline, propane,
kerosene, and other ammable liquids should be stored outside of living
areas in properly-labeled, non-glass safety containers. Do not store them
near a fuel-burning appliance, such as a natural gas water heater in a ga-
rage. If the fuel is spilled or the container is not sealed properly, invisible
vapors from the fuel can travel along the ground and can be ignited by
the appliance’s pilot light or by arcs from electric switches in the appli-
ance.
GROUND FAULT CIRCUIT INTERRUPTER PROTECTION
These generators are equipped with two GFCI (Ground Fault Circuit
Interrupters) 120V duplex receptacles for protection against the hazards
of electrical shock from defective attachments such as, tools, cords, and
cables.
WARNING: THE GFCIS MAY NOT FUNCTION UNLESS THE
GENERATOR IS PROPERLY GROUNDED. FOLLOW THE
CORRECT PROCEDURE SPECIFIED IN THE SECTION
LABELED “GROUNDING INSTRUCTIONS”
A GFCI is a device that interrupts electricity from either the utility or gen-
erator by means of a special type of circuit breaker if a fault current ow
to the ground occurs.
WARNING: ONLY THE 120V DUPLEX RECEPTACLES ARE
PROTECTED BY THE GFCI.
A GFCI can be used only with generators that have the neutral wire
internally bonded to the frame, and the frame properly grounded to the
earth. A GFCI will not work on generators that do not have the neutral
wire bonded to the frame, or on generators which have not been properly
grounded. All Mi-T-M generators have internally bonded ground wires. A
GFCI will not work if the unit is not properly grounded.
A GFCI may be required by OSHA regulations, the National Electric Code
and/or local and federal codes when operating a generator.
For additional protections against shock hazards due to defective equip-
ment attached to the twist-lock receptacles, consider the use of a GFCI
on each of these receptacles as well.
GFCIs and GFCI protected cord sets and cables may be purchased from
local electrical supply houses.

8 Operator’s Manual
ELECTRICAL HAZARDS
This product must be grounded. It has permanent conductor between
the generator (stator winding) and the frame. If it should malfunction or
breakdown, grounding provides a path of least resistance for electric
current to reduce the risk of electric shock.
DANGER - IMPROPER CONNECTION OF THE EQUIPMENT-
GROUNDING CONDUCTOR CAN RESULT IN A RISK OF
ELECTROCUTION. CHECK WITH A QUALIFIED
ELECTRICIAN OR SERVICE PERSON IF YOU ARE
INDOUBT AS TO WHETHER THE UNIT IS PROPERLY
GROUNDED.
This generator is equipped with a grounding terminal for your pro-
tection. Always complete the ground path from the generator to an
external ground source as instructed in the section labeled “Grounding
Instructions” in the Preparation section of this manual.
The generator is a potential source of electrical shock if not kept dry.
Keep the generator dry and do not use in rain or wet conditions. To
protect from moisture, operate it on a dry surface under an open, cano-
py-like structure. Dry your hands if wet before touching the generator.
Risk of electric shock if you operate this generator with a faulty GFCI
(Ground Fault Circuit Interrupter). Test GFCI before each use, see Op-
erations Instructions for further information. If GFCI fails test, DO NOT
use your generator. Contact your Mi-T-M Customer Service Represen-
tative.
Plug appliances directly into the generator. Or, use a heavy duty,
outdoor-rated extension cord that is rated (in watts or amps) at least
equal to the sum of the connected appliance loads. Check that the en-
tire cord is free of cuts or tears and that the plug has all three prongs,
especially a grounding pin.
NEVER try to power the house wiring by plugging the generator into a
wall outlet, a practice known as “back feeding”. This is an extremely
dangerous practice that presents an electrocution risk to utility workers
and neighbors served by the same utility transformer. It also bypasses
some of the built-in household circuit protection devices.
If you must connect the generator to the house wiring to power appli-
ances, have a qualied electrician install the appropriate equipment in
accordance with local electrical codes. Or, check with your utility com-
pany to see if it can install an appropriate power transfer switch.
For power outages, permanently installed stationary generators are
better suited for providing backup power to the home. Even a properly
connected portable generator can become overloaded. This may result
in overheating or stressing the generator components, possibly leading
to a generator failure.

GROUNDING INSTRUCTIONS
This product must be grounded. If it should malfunction or
breakdown, grounding provides a path of least resistance for
electric current to reduce the risk of electric shock.
DANGER - IMPROPER CONNECTION OF THE
EQUIPMENT-GROUNDING CONDUCTOR CAN
RESULT IN A RISK OF ELECTROCUTION. CHECK
WITH A QUALIFIED ELECTRICIAN OR SERVICE
PERSON IF YOU ARE IN DOUBT AS TO WHETHER
THE UNIT IS PROPERLY GROUNDED.
The wing nut and ground terminal on the frame must always be
used to connect the generator to a suitable ground source. The
ground path should be made with #8 size wire. Connect the ter-
minal of the ground wire between the two star washers and wing
nut then tighten the wing nut fully. Connect the other end of the
wire securely to a suitable ground source.
The National Electric Code contains several practical ways in
which to establish a good ground source. Examples given below
illustrate a few of the ways in which a good ground source may
be established.
A metal underground water pipe in direct contact with the earth
for at least 10 feet can be used as a grounding source. If an pipe
is unavailable, an 8 foot length of pipe or rod may be used as the
ground source. The pipe should be 3/4 inch trade size or larger
and the outer surface must be noncorrosive. If a steel or iron rod
is used it should be at least 5/8 inch diameter and if a nonferrous
rod is used it should be at least 1/2 inch diameter and be listed
as material for grounding. Drive the rod or pipe to a depth of 8
feet. If a rock bottom is encountered less than 4 feet down, bury
the rod or pipe in a trench. All electrical tools and appliances
operated from this generator, must be properly grounded by use
of a third wire or be “Double Insulated”.
It is recommended to:
1. Use electrical devices with 3 prong power cords.
2. Use an extension cord with a 3 hole receptacle and a 3 prong
plug at the opposite ends to ensure continuity of the ground
protection from the generator to appliance.
We strongly recommend that all applicable federal, state and
local regulations relating to grounding specications be checked
and followed.
LINE TRANSFER SWITCH
If this generator is used for standby service, it must have a trans-
fer switch between the utility power service and the generator.
The transfer switch not only prevents the utility power form feed-
ing into the generator, but is also prevents the generator form
feeding out into the utility company’s lines. This is intended to
protect the serviceman who may be working on a damaged line.
THIS INSTALLATION MUST BE DONE BY A LICENSED ELEC-
TRICIAN AND ALL LOCAL CODES MUST BE FOLLOWED.

Use oil viscosity based on the expected air temperature
range during the period between oil changes.
Use a high quality detergent oil with API classications of
SJ or higher.
Check oil level before each operation and ensure that it is
maintained.
CAUTION: THIS ENGINE CRANKCASE IS NOT
FILLED WITH OIL AT THE FACTORY, SO BE
SURE TO FILL IT BEFORE OPERATING THE
ENGINE.
ENGINE OIL CAPACITY
NOTE: These engines are equipped with a “Low Oil”
shut-off system for engine protection. If the engine
fails to start, check engine crankcase for oil.
To ll with oil:
1. Level the engine to ensure accurate inspection and to
prevent overlling.
2. Unscrew the oil gauge (Fig. 1), wipe the dipstick dry.
Reinsert the oil gauge back into the oil ll gauge opening.
Remove the oil gauge and check the oil level.
3. The oil level should be between the full and low marks
on the dipstick. (Fig. 2)
NOTE: When checking the oil be sure the engine is
level.
4. Fill with oil as required through the oil ll gauge opening.
5. Replace the oil gauge and screw in rmly.
6. Wipe up any spilled oil.
FUELING
WARNING: EXPLOSIVE FUEL! GASOLINE IS
EXTREMELY FLAMMABLE AND ITS VAPORS
CAN EXPLODE IF IGNITED.
STORE GASOLINE ONLY IN APPROVED
CONTAINERS, IN WELL VENTILATED,
UNOCCUPIED BUILDINGS AND AWAY FROM
SPARKS OR FLAMES.
DO NOT FILL THE FUEL TANK WHILE THE
ENGINE IS HOT OR RUNNING, SINCE
SPILLED FUEL COULD IGNITE IF IT COMES
IN CONTACT WITH HOT PARTS OR SPARKS
FROM IGNITION. DO NOT START THE ENGINE
NEAR SPILLED FUEL.
NEVER USE GASOLINE AS A CLEANING
AGENT.

PREPARING THE GENERATOR
WARNING: DO NOT OVERFILL THE FUEL TANK, LEAVE ROOM
FOR THE FUEL TO EXPAND.
GENERAL RECOMMENDATIONS
•Purchase gasoline in small quantities and store in clean, approved
containers.
•To minimize gum deposits in your fuel system and to insure easy
starting, do not use gasoline left over from the previous season.
•Do not add oil to the gasoline.
FUEL TYPE
•For best results use only clean, fresh, unleaded gasoline with a
pump sticker octane rating of 87 or higher.
•Unleaded gasoline is recommended as it leaves less combustion
chamber deposits.
GASOLINE/ALCOHOL BLENDS:
Gasohol (up to 10% ethyl alcohol, 90% unleaded gasoline by volume) is
approved, as a fuel. Other gasoline/alcohol blends are not approved.
GASOLINE/ETHER BLENDS:
Methyl Tertiary Butyl Ether (MTBE) and unleaded gasoline blends (up
to a maximum of 15% MTBE by volume) are approved as a fuel. Other
gasoline/ether blends are not approved.
BATTERY INSTALLATION
WARNING: SHOULD ONLY BE DONE BY AN AUTHORIZED
DEALER.
HIGH ALTITUDE
At high altitude, the standard carburetor air/fuel mixture will be too rich.
Performance will decrease, and fuel consumption will increase. A very
rich mixture will also foul the spark plug and cause hard starting. Opera-
tion at an altitude that differs from that at which this engine was certi-
ed, for extended periods of time, may increase emissions.
High altitude performance can be improved by specic modications
to the carburetor. If you always operate your generator at altitudes
above 5,000 feet (1,500 meters), have your dealer perform this carbure-
tor modication. This engine, when operated at high altitude with the
carburetor modications for high altitude use, will meet each emission
standard throughout its useful life.
Even with carburetor modication, engine horsepower will decrease
about 3.5% for each 1,000-foot (300-meter) increase in altitude. The
effect of altitude on horsepower will be greater than this if no carburetor
modication is made.
NOTE:When the carburetor has been modified for high altitude op-
eration, the air/fuel mixture will be too lean for low altitude use.
Operation at altitudes below 5,000 feet (1,500 meters) with a
modified carburetor may cause the engine to overheat and result
in serious engine damage.
For use at low altitudes, have your servicing dealer return the carburetor
to original factory specications.

information.
WARNING: NEVER EXCEED THE RATING OF A RECEPTACLE.
THESE RECEPTACLES ARE PROTECTED AGAINST
OVERLOADS BY RESETTING MAGNETIC TYPE CIRCUIT
BREAKERS. IF A CIRCUIT BREAKER TRIPS, THE CAUSE
SHOULD BE DETERMINED AND CORRECTED PRIOR TO
CONTINUING USE.CONTROLS
VFT METER:
The generator is equipped with a display to show the voltage, frequency,
total accumulated hours of operation, and current hours. To change the
readout of the display to the desired setting, press the toggle switch.
The display will show 3 maintenance messages when running:
1. P-25 displays after the rst 25 hours of running to remind the user to
change the oil.
2. P-50 displays after every 50 hours of use to remind user to change
engine oil and check spark arrestor.
3. P-100 displays after 100 hours of use to remind user to change engine
oil and check spark plug.
These codes fade away after 6 minutes of use.
IDLE CONTROL OPERATION:
The idle control is factory installed. This electrical device is designed to
let the engine run at fuel saving low idle speed when the generator is not
loaded, and at full normal governed speed when a load is applied. The
idle system overrides the engine governor to provide idle speed. When
a load is applied, the electronic circuit reacts to de-energize the idle sys-
tem so that the engine can resume full governed operating speed.
The idle control system controls the engine speed in the following man-
ner:
1. With the idle control switch in the “OFF” position, start the engine.
2. After one or two minute warm up period, apply load and move the
switch to the “ON” position. The engine will throttle back to idle speed
following a 5-8 second delay.
3. Whena loadis appliedto the generator, the idle controlsystem becomes
de-energized. The engine then accelerates to normal operating speed,
controlled by the governor.
4. When the load is removed, the idle system becomes re-energized and
throttles the engine back to idle speed after a 5-8 second delay.
NOTE: While the engine is idling, the generator voltage is automati-
cally reduced to reduce generator temperatures. The voltage will
return to normal levels immediately upon the application of load.
MAIN BREAKER (GEN-6000 UNITS ONLY):
These generators are equipped with a main circuit breaker which pro-
tects the unit in an overload condition. This main breaker must be “ON”
for any power to be drawn from the unit.

Operator’s Manual 19
CABLE SIZE:
Equipment damage can result from low voltage. Therefore, to prevent excessive voltage drop between the genera-
tor and the equipment, the cable should be of adequate gauge for the length used. The cable selection chart gives
the maximum cable lengths for various gauges of wire which can adequately carry the loads shown.
ELECTRIC MOTOR LOADS:
It is characteristic of common electric motors in normal operation to draw up to six times their running current
while starting. This table may be used to estimate the watts required to start “CODE G” electric motors.
CAUTION: IF AN ELECTRIC MOTOR FAILS TO START OR REACH RUNNING SPEED, TURN OFF THE
APPLIANCE OR TOOL IMMEDIATELY TO AVOID EQUIPMENT DAMAGE. ALWAYS CHECK THE
REQUIREMENTS OF THE TOOL OR APPLIANCE BEING USED COMPARED TO THE RATED OUTPUT
OF THE GENERATOR.
