CARBON MONOXIDE - POISONOUS GAS
Use unit outdoors, away from open windows, vents, or doors.
Unit exhaust contains carbon monoxide - a poisonous gas that can kill you.
You CAN NOT smell or see this gas.
Never use the unit in enclosed or partially-enclosed spaces. The unit can
produce high levels of carbon monoxide very quickly. When you use this
unit, remember that you cannot smell or see carbon monoxide. Even if you
can’t smell exhaust fumes, you may still be exposed to carbon monoxide.
If you start to feel sick, dizzy, or weak while using the unit, get to fresh air
RIGHT AWAY. DO NOT DELAY. The carbon monoxide from the unit can rap-
idly lead to full incapacitation and death.
If you experience serious symptoms, get medical attention immediately.
Inform medical staff that carbon monoxide poisoning is suspected. If you
experienced symptoms while indoors, have someone call the re depart-
ment to determine when it is safe to re-enter the building.
Never operate the unit in an explosive atmosphere, near combustible ma-
terials or where ventilation is not sufcient to carry away exhaust fumes.
Exhaust fumes can cause serious injury or death.
NEVER use the unit indoors, including in homes, garages, basements, crawl
spaces, and other enclosed or partially-enclosed areas, even with ventila-
tion. Opening doors and windows or using fans will not prevent carbon
monoxide build-up in the home.
Follow the instructions that come with your unit. Locate the unit outdoors
and away from doors, windows, and vents that could allow the carbon mon-
oxide gas to come indoors.
ONLY run unit outdoors and away from air intakes.

Operator’s Manual 5
SAFETY
NEVER run unit inside homes, garages, sheds, or other semi-enclosed spac-
es. 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 unit, shut if off and
get fresh air IMMEDIATELY. See a doctor. You may have carbon monoxide
poisoning.
Install battery-operated carbon monoxide alarms or plug-in carbon monox-
ide alarms with battery back-up in your home, according to the manufactur-
er’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 batteries.
SAFETY WARNING WHEN REFUELING
Injury or death may occur as a result of improper fueling. Do not smoke
while lling engine fuel tank.
Always refuel slowly to avoid the possibility of spilled fuel which may cause
a risk of re.
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.
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 unit 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 garage. 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 appliance.
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. Do not touch live electrical parts.
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 unit is equipped with a grounding terminal for your protection. Always
complete the ground path from the unit to an external ground source as
instructed in the section labeled “Grounding Instructions” in the Preparation
section of this manual.
The unit is a potential source of electrical shock if not kept dry. Keep the unit
dry and do not use in rain or wet conditions. To protect from moisture, oper-
ate it on a dry surface under an open, canopy-like structure. Dry your hands
if wet before touching the unit.

6 Operator’s Manual
Plug appliances directly into the unit. 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 entire 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 unit 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 unit to the house wiring to power appliances, have a
qualied electrician install the appropriate equipment in accordance with lo-
cal electrical codes. Or, check with your utility company to see if it can install
an appropriate power transfer switch.
For power outages, permanently installed stationary units are better suited
for providing backup power to the home. Even a properly connected porta-
ble unit can become overloaded. This may result in overheating or stressing
the unit components, possibly leading to a unit failure.
Do not use worn, damaged, undersized, or poorly spliced welding cables.
Do not drape welding cables over your body. Do not touch electrode if you
are in contact with the work, ground, or another electrode from a different
machine.
RISK OF FIRE OR EXPLOSION
Serious injury or death may occur from normal sparks in the engine igni-
tion system or engine exhaust/mufer. Always operate the unit in a well
ventilated area free of ammable vapors, combustible dust, gases or other
combustible materials. Do not weld where the atmosphere may contain
ammable dust, gas, or liquid vapors (such as gasoline).
DO NOT SMOKE if spraying ammable material. Locate the unit at least 20
feet away from the spray area. (An additional hose may be required.)
Never ll the engine fuel tank while the engine is running or hot. Allow the
engine to cool two minutes before refueling. Do not refuel indoors or in a
poorly ventilated area.
Do not operate the unit if gasoline is spilled. Wipe the unit clean and move
it away from the spill. Avoid creating any ignition until the gasoline has
evaporated.
Do not store the unit near an open ame or any equipment such as a stove,
furnace, water heater, etc. which utilizes a pilot light or sparking device.
A spark arrester must be added to the mufer of this engine if it is to be
used on any forest covered, brush covered or grass covered unimproved
land. The arrester must be maintained in effective working order by the
operator.
Serious injury may occur if any of the unit's ventilation openings are restrict-
ed, causing the unit to overheat and start a re. Never place objects against
or on top of the unit. Operate the unit at least 12 inches away from any wall
or obstruction that would restrict proper ventilation.
Welding on closed containers, such as tanks, drums, or pipes, can cause
them to explode. Accidental contact of electrode to metal objects can cause
sparks, explosion, overheating, or re.
Remove all ammables within 35 ft (10.7 m) of the welding arc. Do not weld
where ying sparks can strike ammable material. Watch for re, and keep a
re extinguisher nearby.
SAFETY

Operator’s Manual 7
After completion of work, inspect area to ensure it is free of sparks, glowing
embers, and ames. Remove stick electrode from holder when not in use.
RISK OF BURSTING
Serious injury or death may occur from an air tank explosion if air tanks are
not properly maintained. Drain air tank daily or after each use to prevent
moisture buildup in the air tank.
If air tank develops a leak, replace the air tank immediately. Never repair,
weld or make modications to the air tank or its attachments. Use only
genuine manufacturer repair parts for your unit. NEVER make adjustments
to the factory set pressures.
Serious injury may occur from the unit malfunction or exploding accesso-
ries if incorrect system components, attachments or accessories are used.
Never exceed manufacturers maximum allowable pressure rating of attach-
ments.
Because of extreme heat, do not use plastic pipe or lead tin soldered joints
for a discharge line.
Never use the unit to inate small, low pressure objects such as toys.
RISK OF BREATHING
Serious injury or death could occur from inhaling compressed air. The air
stream may contain carbon monoxide, toxic vapors or solid particles. Never
inhale air from the unit either directly or from a breathing device connected
to the unit.
Serious injury or death may occur from inhaling engine exhaust. This unit
was designed for outdoor use. Never operate this unit in an enclosed
area. Always make certain there is adequate ventilation (fresh outside air)
for breathing and combustion. This will prevent the buildup of dangerous
carbon monoxide gases. Beware of poorly ventilated areas, or areas with
inadequate exhaust fans.
Sprayed materials such as paint, solvents, paint remover, insecticides,
weed killers, etc. contain harmful vapors and poisons. Operate the unit only
in a well ventilated area. Follow all safety instructions provided with the ma-
terials you are spraying. Use of a respirator may be required when working
with some materials.
Welding produces fumes and gases. Breathing these fumes and gases
can be hazardous to your health. Keep your head out of the fumes. Do not
breathe the fumes.
Do not weld in locations near degreasing, cleaning, or spraying operations.
The heat and rays of the arc can react with vapors to form highly toxic and
irritating gases.
Do not weld on coated metals, such as galvanized, lead, or cadmium plated
steel. The coatings and any metals containing these elements can give off
toxic fumes if welded.
RISK OF BURNS
Serious injury could occur from touching exposed metal parts. These areas
can remain hot for some time after the unit is shutdown. Never allow any
part of your body or other materials to make contact with any exposed
metal parts on the unit.
Never allow any part of your body to contact the engine mufer, compressor
head or adjacent areas.

INSTALLATION

14 Operator’s Manual
INSTALLATION
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 screw and ground terminal on the frame must always be used to con-
nect the unit to a suitable ground source. The ground path should be made
with #8 size wire. Connect the terminal of the ground wire between the star
washers and screw then tighten the screw 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 es-
tablish 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 a 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 unit, 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 unit
to appliance.
Mi-T-M strongly recommends that all applicable federal, state and local
regulations relating to grounding specications be checked and followed.
LINE TRANSFER SWITCH:
If this unit is used for standby service, it must have a transfer switch be-
tween the utility power service and the unit. The transfer switch not only pre-
vents the utility power from feeding into the unit, but also prevents the unit
from 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 ELECTRI-
CIAN AND ALL LOCAL CODES MUST BE FOLLOWED.
GASOLINE ENGINE

Operator’s Manual 17
INSTALLATION
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. Operation 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 unit 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 modified for high altitude opera-
tion, the air/fuel mixture will be too lean for low altitude use. Op-
eration at altitudes below 5,000feet (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 carbu-
retor to original factory specifications.

18 Operator’s Manual
PRE-OPERATION:
Check the engine oil level before starting. (See engine manual.) Fill the fuel
tank according to the engine manual instruction.
Pump oil level should be checked before each use. Check the oil level
indicator on the pump crankcase. Make certain the oil is in the center of the
oil sight glass. If the level appears to be low, ll with SAE20 or 30 non-deter-
gent pump oil.
Remove any moisture in the unit's air tank.
WARNING: NEVER ATTEMPT TO OPEN THE AIR TANK DRAIN

SHUTDOWN:
1. Remove all load by turning off electrical appliances and unplugging electric/
welding cords.
2. Move the Engine Switch to the "Off" position. (Refer to the Engine Manual
accompanying this unit.)
3. Move the GEN/WELD switch to the GEN position.
4. Drain air from the air tanks by releasing air with an attached air tool or by
pulling on the Safety Relief Valve.
5. Once the Air Tank Pressure Gauge registers under 10 pounds, open the
drain valve under each air tank to drain any moisture.
6. Close fuel valve on unit or engine.
7. Wipe the unit clean and store in a safe, non-freezing, dry area.
NOTE: Failure to allow the engine to cool at idle for two (2) minutes may
result in damage to the generator.
OPERATING CONTROLS
IDLE CONTROL OPERATION:
Note: Idle control is disabled in welding mode. Idle control switch must
be at full throttle setting.
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 or compres-
sor are not loaded, and at full normal governed speed when a load is ap-
plied. 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
system so that the engine can resume full governed operating speed.
The idle control system controls the engine speed in the following manner:
1. With the idle control switch in the “FULL THROTTLE” position, start the
engine.
2. After one or two minute warm up period, apply load and move the switch to
the “IDLE CONTROL” position. The engine will throttle back to idle speed
following a 5-8 second delay.
3. When a load is applied to the generator or air compressor tank pressure drops
below regulated set point. The idle control system becomes de-energized.
The engine then accelerates to normal operating speed, controlled by the
governor.
4. When the load is removed or air compressor tank pressure is restored, 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 automatically
reduced to reduce generator temperatures. The voltage will return to
normal levels immediately upon the application of load.
