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 RIGHTAWAY. DO NOT DELAY. The carbon monoxide from
the unit can rapidly 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 department to determine when it is safe to
re-enter the building.
Never operate the unit in an explosive atmosphere, near combustible
materials 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 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 unit. Locate the unit
outdoors and away from doors, windows, and vents that could allow
the carbon monoxide gas to come indoors.
ONLY run unit outdoors and away from air intakes.
NEVER run unit 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 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
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
batteries.

Operator’s Manual 7
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.

8 Operator’s Manual
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 ELECTRI-
CIAN 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, operate it on a dry surface under an open, canopy-like
structure. Dry your hands if wet before touching the unit.
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 qualified electrician install the appropriate equipment in
accordance with local 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 portable 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.

Operator’s Manual 9
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
accessories if incorrect system components, attachments or accessories
are used. Never exceed manufacturers maximum allowable pressure
rating of attachments.
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 FIRE OR EXPLOSION
Serious injury or death may occur from normal sparks in the engine
ignition 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
restricted, 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.
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.

10 Operator’s Manual
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 materials 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.

Operator’s Manual 11
RISK OF FLYING OBJECTS
Soft tissue damage can occur from the compressed air stream. Always wear
safety glasses to shield the eyes from ying debris.
Never point the air stream at any part of your body, anyone else or animals.
Never leave pressurized air in the unit. Shut off the unit and relieve pressure
when storing or attempting maintenance.
Serious injury can occur from loose debris being propelled at a high speed
from the compressed air stream. Always maintain a safe distance from
people and animals while operating the unit.
Do not move the unit while air tank is under pressure. Do not attempt to
move the unit by pulling on the hose.
RISK FROM MOVING PARTS

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 ELECTRI-
CIAN 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 connect 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 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 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
between the utility power service and the unit. The transfer switch
not only prevents 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
ELECTRICIAN AND ALL LOCAL CODES MUST BE FOLLOWED.
