EMF INFORMATION
The following is a quotation from the General Conclusions Section of
the U.S. Congress, Office of Technology Assessment, Biological
Effects of Power Frequency Electric & Magnetic Fields
Background Paper, OTA-BP-E-53 (Washington, DC: U.S.
Government Printing Office, May 1989): “. . . there is now a very large
volume of scientific findings based on experiments at the cellular
level and from studies with animals and people which clearly
establish that low frequency magnetic fields can interact with, and
produce changes in, biological systems. While most of this work is
of very high quality, the results are complex. Current scientific
understanding does not yet allow us to interpret the evidence in a
single coherent framework. Even more frustrating, it does not yet
allow us to draw definite conclusions about questions of possible risk
or to offer clear science-based advice on strategies to minimize or
avoid potential risks.”
To reduce magnetic fields in the workplace, use the following
procedures:
1. Keep cables close together by twisting or taping them.
2. Arrange cables to one side and away from the operator.
3. Do not coil or drape cables around the body.
4. Keep welding power source and cables as far away as practical.
5. Connect work clamp to workpiece as close to the weld as
possible.
About Pacemakers:
The above procedures are among those also normally
recommended for pacemaker wearers. Consult your doctor for
complete information.

WARNING
ENGINE EXHAUST GASES can kill.
Do not breathe exhaust fumes.
Use in open, well-ventilated areas, or vent exhaust
outside and away from building air intakes.
ENGINE EXHAUST SPARKS can cause
fire.
Use only U.S. Forestry Department approved spark
arrestor and comply with all local, state, and federal
laws.
A spark arrestor is mandatory in all National Forests
and in grass, brush, or forest covered lands in
California, Oregon, and Washington. Check with
state and local authorities in other areas.
Properly maintain the spark arrestor.
Stop engine and allow exhaust system to cool down
before servicing spark arrestor.
Service spark arrestor away from flammables.

PIPE can cause fires.
Keep exhaust and pipe away from flammables.
FALLING EQUIPMENT can cause
serious personal injury and equipment
damage.
Use lifting eye to lift unit only, NOT running gear, gas
cylinders, trailer, or any other heavy options,
accessories, or devices.
Use equipment of adequate capacity to lift the unit.
TILTING OF TRAILER can result in
personal injury or equipment damage.
Install unit properly on trailer (if applicable)
according to trailer manual.

IMPROPER HANDLING OR EXPOSURE TO ETHER
can seriously harm your health.
Follow manufacturer’s safety instructions on cylinder.
INJECTING ETHER WHILE ENGINE IS RUNNING
can damage engine.
Do not use Ether Starting Aid while engine is running.
After installing cylinder, wait at least 10 minutes before use to let ether
particles settle to prevent atomizer plugging.

Do not weld near flammable material.
Watch for fire; keep extinguisher nearby.
Do not locate unit over combustible surfaces.
Do not weld on closed containers.
Allow work and equipment to cool before handling.
ARC RAYS can burn eyes and skin;
NOISE can damage hearing.
Wear welding helmet with correct shade of filter.
Wear correct eye, ear, and body protection.
FUMES AND GASES can be hazardous.
Keep your head out of the fumes.
Ventilate area, or use breathing device.
Read Material Safety Data Sheets (MSDSs) and
manufacturers instructions for material used.
ENGINE EXHAUST GASES can kill.
Do not breathe exhaust fumes.
Use in open, well-ventilated areas, or vent exhaust
outside and away from any building air intakes.
ENGINE FUEL can cause fire or explo-
sion.
Stop engine before fueling.
Do not fuel while smoking or near sparks or flames.
Do not overfill tank; clean up any spilled fuel.
MOVING PARTS can cause injury.
Keep away from moving parts such as fans, belts,
and rotors.
Keep all doors, panels, covers, and guards closed
and securely in place.
MAGNETIC FIELDS FROM HIGH CUR-
RENTS can affect pacemaker operation.
Pacemaker wearers keep away.
Wearers should consult their doctor before going
near any welding operations.
See Safety Precautions at beginning of manual for ba-
sic welding safety information.

INJECTING ETHER WHILE ENGINE IS RUNNING can damage engine.
Do not use Ether Starting Aid while engine is running.
After installing cylinder, wait at least 10 minutes before use to let ether particles settle to prevent atomizer plugging.

1 Engine Control Switch
Use switch to start and stop engine.
To start, turn switch to Start position
and release as soon as engine
starts. Do not engage starter while
flywheel is rotating.
In Run position, engine runs at weld
speed all the time.
To stop engine, turn switch to Off
position.
If unit has optional overspeed shut-
down kit, engine stops automatical-
ly when speed exceeds normal
rpm.
2 Ether Starting Aid Switch
Push switch up and release while
cranking engine. Ether is sprayed
into engine manifold when switch is
released.

1 Engine Hour Meter
Use meter to check total operating
hours (see Section 6-1).
2 Fuel Gauge
Use gauge to check fuel level in fuel
tank.
3 Battery Ammeter
Use ammeter to check amperage
output to the battery. The ammeter
reads near 0 (zero) when the en-
gine is running. If ammeter is at a
negative number, the battery is dis-
charging. Stop engine, and do not
run until problem is fixed.
4 Oil Pressure Gauge/Shut-
down Switch
Use gauge/switch to check oil pres-
sure. Normal operating pressure is
about 50 psi (345 kPa). If oil pres-
sure drops to 30 psi (207 kPa),
switch closes and engine stops.
5 Oil Temperature Gauge/Shut-
down Switch
Use gauge/switch to check oil tem-
perature. Normal operating temper-
ature is about 225°F (107° C). If oil
temperature rises to 250°F (121°
C), switch closes and engine stops.
