ARC WELDING SAFETY INSTRUCTIONS AND WARNINGS
Instruction 830001
FUMES AND GASES can be hazardous
to your health.
Weldingproducesfumesandgases.Breathingthese
fumes and gases can be hazardous to your health.
1. Keep your head out of the fumes. Do not breath the fumes.
2. If inside, ventilate the area and/or use exhaust at the arc to
remove welding fumes and gases.
3. If ventilation is poor, use an approved air-supplied respirator.
WELDING can cause fire or explosion.
Sparks and spatter fly off from the welding arc. The
flying sparks and hot metal, weld spatter, hot workpiece, and hot equipment cancausefiresand burns.
Accidental contact of electrode or welding wire to
metal objects can cause sparks, overheating, or fire.
1. Protect yourself and others from flying sparks and hot metal.
2. Do not weld where flying sparks can strike flammable material.
3. Remove all flammables within 35 ft (10.7 m) of the welding arc.
If this is not possible, tightly cover them with approved covers.
4. Be alert that welding sparks and hot materials from welding can
easily go through small cracks and openings to adjacent areas.
4. Read the Material Safety Data Sheets (MSDSs) and the manufacturer’s instruction for metals, consumables, coatings, and
cleaners.
5. Work in a confined space only if it is well ventilated, or while
wearing an air-supplied respirator. Shielding gases used for
welding can displace air causing injury or death. Be sure the
breathing air is safe.
6. Do not weld in locations near degreasing, cleaning, or spraying
operations. The heat and raysofthearccanreactwithvapors to
form highly toxic and irritating gases.
7. Do not weld on coated metals, such as galvanized, lead, or
cadmium plated steel, unless the coating is removed from the
weld area, the area is well ventilated, and if necessary, while
wearing an air-supplied respirator. The coatings and any metals
containing these elements can give off toxic fumes if welded.
5. Watch for fire, and keep a fire extinguisher nearby.
6. Be aware that welding on a ceiling, floor, bulkhead, or partition
can cause fire on the hidden side.
7. Do not weld on closed containers such as tanks or drums.
8. Connect work cable to the work as close to the welding area as
practical to prevent welding current from traveling long, possibly
unknown paths and causing electric shock and fire hazards.
9. Do not use welder to thaw frozen pipes.
10. Remove stick electrode from holder or cut off welding wire at
contact tip when not in use.
11. Wear oil-free protective garments such as leather gloves, heavy
shirt, cuffless trousers, high shoes, and a cap.
FLYING SPARKS AND HOT METAL can
cause injury.
Chipping and grinding cause flying metal. As welds
cool, they can throw off slag.
CYLINDERS can explode if damaged.
Shielding gas cylinderscontaingasunderhighpressure. If damaged, a cylinder can explode. Since gas
cylinders are normally part of the welding process,
be sure to treat them carefully.
1. Protectcompressed gascylindersfromexcessiveheat,mechanical shocks, and arcs.
2. Install and secure cylinders in an upright position by chaining
themtoastationarysupportorequipment cylinderracktoprevent
falling or tipping.
ENGINE EXHAUST GASES can kill.
Engines produce harmful exhaust gases.
1. Wear approved face shield or safety goggles. Side shields recommended.
2. Wear proper body protection to protect skin.
3. Keep cylindersawayfrom any welding orotherelectrical circuits.
4. Never allow a welding electrode to touch any cylinder.
5. Use only correct shielding gas cylinders, regulators, hoses, and
fittings designed for the specific application; maintain them and
associated parts in good condition.
6. Turn face away from valve outlet when opening cylinder valve.
7. Keep protective cap in place over valve except when cylinder is
in use or connected for use.
8. Read and follow instructionsoncompressedgas cylinders, associated equipment, and CGA publication P-1 listed in Safety
Standards.
ENGINES can be hazardous.
1. Use equipment outside in open, well-ventilated areas.
2. If used in a closed area, vent engine exhaust outside and away
from any building air intakes.

of California to cause birth defects and, in some cases, cancer. (California Health & Safety Code Sec. 25249.5 et seq.)
NOTE: Considerations About Welding And The Effects Of Low Frequency Electric And Magnetic Fields
The following is a quotation from the General Conclusions Section of the U.S. Congress, Office of Technology Assessment,
of Power Frequency Electric& Magnetic Fields — Background Paper, OTA-BP-E-63 (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.
2. Do not addfuelwhile smokingorif unitisnear anysparksor open
flames.
3. Allow engine to cool before fueling. If possible, check and add
fuel to cold engine before beginning job.
4. Do not overfill tank — allow room for fuel to expand.
5. Do not spillfuel.Iffuelisspilled,clean up before starting engine.
3. Have only qualified people remove guards or covers for mainte-
nance and troubleshooting as necessary.
4. To prevent accidentalstartingduring servicing, disconnectnega-
tive (-) battery cable from battery.
5. Keep hands, hair, loose clothing, and tools away from moving
parts.
6. Reinstall panels or guards and close doors when servicing is
finished and before starting engine.
1. Always wear a face shield when working on a battery.
2. Stop engine before disconnecting or connecting battery cables.
3. Do not allow tools to cause sparks when working on a battery.
4. Do not use welder to charge batteries or jump start vehicles.
5. Observe correct polarity (+ and –) on batteries.
1. Do not remove radiator cap when engine is hot. Allow engine to
cool.
2. Wear gloves and put a rag over cap area when removing cap.
3. Allow pressure to escape before completely removing cap.
Biological Effects
3. Do not coil or drape cables around the body.
4. Keep welding power source and cables as far away from body as
practical.

6. Test fit fuel shutoff pulley on the shutoff valve to be sure it seats properly on the valve shaft shoulders.
The flat part of thepulley should face away from theengine fan. (Ifit does not seat properly, the shutoff valve
will not function correctly.)
7. On models MA-4030D and MA-4535D (3-cylinder engine), the fuel line may need to be removed from
the filter at the fan end of the injection pump in order to complete Steps 8 to 12. (See Note, Step 13.) On
some older 3-cylinder engines, itmay be necessary touse a file to remove awebof material located between
the stop post and the shutoff valve post. File web down until it is flush with pump body. Refer to Figure 3.
8. Place torsion spring supplied in kit over shutoff valve post withstraight leg down and positionedbetween
the valve post and the stop post.
9.With flat part of pulley facing away from the
engine fan, place the pulley onto the shutoff
valve screw and insert onto valve shaft shoulder. Be sure the pulley seats properly as it did
in Step 6.
10. Replace nut and lockwasher and secure
on valve screw.
11. Rotate torsion spring counterclockwise
untiltheverticalarm of the spring locks into the
large hole in the end of the fuel shutoff arm.
12. Check pulley operation.Ifthe pulley does
notreturn when rotated andreleased, then the
pulley and/or spring may not beinstalledproperly. Recheck assembly positioning. (Refer to
Figure 3 for installation sequence.)
13. Reinstall fuel line removed in Step 7.
Assure clearance between pulley and fuel line
after installation. Fuel line may require some
slight reforming. (Disregard this step for MA-
