Operator’s Manual 5
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.

6 Operator’s Manual
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.

Operator’s Manual 7
ELECTRICAL HAZARDS
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.
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 representa-
tive.
Plug appliances directly into the generator. Or, use a heavy duty, out-
door-rated extension cord that is rated (in watts or amps) at least equal
to the sum of the connected appliance loads. Check that the entire
cord is free of cuts or tears and that the plug has all three prongs, es-
pecially 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
ELECTRICIAN AND ALL LOCAL CODES MUST BE
FOLLOWED.

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.
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 gaso-
line/ether blends are not approved.
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 carburetor 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 modied for high altitude operation, the air/fuel
mixture will be too lean for low altitude use. Operation at altitudes below 5,000 feet
(1,500 meters) with a modied 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 fac-
tory specications.

OIL WARNING DEVICE:
NOTE: This engine is equipped with a “Low Oil” shutdown system for engine
protection. The engine stops when the oil level gets too low. The engine
will not restart without adding oil. If the unit is tilted too much during
operation, it may suddenly stop even though the oil level is not low.
Check the engine oil before restarting the engine. If the unit is tilted,
level the engine, then check the oil before restarting the engine.

OPERATING THE GENERATOR
CONTROLS
CABLE SIZE:
Equipment damage can result from low voltage. Therefore, to prevent
excessive voltage drop between the generator 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 mo-
tors.
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.

Keep all air vents clear.
Keep the generator clean. DO NOT spray with water.
Periodically check all fasteners and tighten, see the periodic maintenance chart.
GFCI TEST RECORDS:
As with any other safety devices, the GFCIs supplied with these generators must be checked every month to insure that
they are functioning properly. To test the GFCIs, follow the instructions and then enter the date of the test below.
1. With the generator running and the idle control switch in the “START” position, push the “TEST” button. The
“RESET” button should pop out. This should result in the power being off at both outlets of the duplex receptacle.
Verify this by plugging a test lamp into each outlet.
WARNING: IF THE RESET BUTTON DOES NOT POP OUT, DO NOT USE THE RECEPTACLE(S). SEE
AUTHORIZED MI-T-M CUSTOMER SERVICE REPRESENTATIVE FOR SERVICE IMMEDIATELY.
2. If the GFCI test correctly, restore power by FIRMLY pushing the “RESET” button back in until you hear or feel a distinctive
“click”. IF THE GFCI FAILS TO RESET PROPERLY, DO NOT USE EITHER OUTLET OF THE DUPLEX RECEPTACLE.
Have the unit serviced by an authorized Mi-T-M Customer Service Representative immediately.
3. High vibration or severe mechanical shock loads may cause the GFCIs to trip. IF EITHER GFCI TRIPS BY
ITSELF AT ANY TIME, reset it and perform test procedures 1 and 2.
4. Repeat steps 1-3 for the second GFCI.
WARNING: ALTHOUGH THE ABOVE TEST PROCEDURES WILL INDICATE PROPER GFCI OPERATION
ON AN UNGROUNDED OR IMPROPERLY GROUNDED GENERATOR, THE GENERATOR MUST STILL
BE GROUNDED PER THE GROUNDING INSTRUCTIONS LISTED IN THIS MANUAL FOR THE GFCI TO
FUNCTION PROPERLY AND PROTECT THE USER FROM ELECTRICAL FAULTS.
SERVICE
Year Jan. Feb. March April May June July Aug. Sept. Oct. Nov. Dec.
NOTE: Situations exist where a GFCI will not afford any protection against the hazards of electrical shock.
EXAMPLE: if a person touches two or more conductors from a damaged cord set and is not in direct contact with the ground, he or she
may receive a shock. Since there is no path to ground for a ground fault current to ow through, the GFCI will not operate and seri-
ous injury may result.
The GFCI are merely an added safety feature. There are no substitutes for good safety precautions, correct electrical practices and proper
maintenance of cords, equipment and connections.
