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.

Stop engine before fueling.
Do not fuel while smoking or near sparks or flames.
Do not overfill tank; clean up any spilled fuel.
USE OF GASOLINE will damage engine.
Do not use gasoline.
Lack of lubrication in gasoline damages injector pump
and injectors.
REMOVE FUEL CAP SLOWLY; FUEL
SPRAY may cause injury; FUEL may be
under pressure.
Rotate fuel cap slowly and wait until hissing stops
before removing cap.
rwarn3.1* 3/93
rsb4.2 11/92 ST-156 467-B
Check all fluids daily. Engine must
be cold and on a level surface.
Add fresh fuel before starting
engine the first time (see
Figure 6-2).

Do not run out of fuel or air enters
fuel system and causes starting
problems.

WARNING
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.

SECTION 4 OPERATING THE WELDING GENERATOR
ELECTRIC SHOCK can kill.
Do not touch live electrical parts.
Always wear dry insulating gloves.
Insulate yourself from work and ground.
Stop engine before installing or servicing.
Keep all panels and covers securely in place.
WELDING can cause fire or explosion.
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.
