CYLINDERS can explode if damaged.
Shielding gas cylinders contain gas under high pressure. If damaged, a cylinder can explode. Since gas cylinders are normally part of the welding process, be sure to treat them carefully.
4.Never drape a welding torch over a gas cylinder.
5.Never allow a welding electrode to touch any cylinder.
6.Never weld on a pressurized cylinder ± explosion will result.
7.Use only correct shielding gas cylinders, regulators, hoses, and fittings designed for the specific application; maintain them and associated parts in good condition.
1.Protect compressed gas cylinders from excessive heat, mechanical shocks, slag, open flames, sparks, and arcs.
2.Install cylinders in an upright position by securing to a stationary

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.
5.Watch for fire, and keep a fire extinguisher nearby.
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.

12.Remove any combustibles, such as a butane lighter or matches, from your person before doing any welding.
1-3. Engine Hazards
WARNING
ENGINE EXHAUST GASES can kill.
Engines produce harmful exhaust gases.
1.Use equipment outside in open,
2.If used in a closed area, vent engine exhaust outside and away from any building air intakes.
| ENGINE FUEL can cause fire or |
| explosion. |
| Engine fuel is highly flammable. |
1. | Stop engine and let it cool off before checking or adding fuel. |
2.Do not add fuel while smoking or if unit is near any sparks or open flames.
3.Do not overfill tank ± allow room for fuel to expand.
4.Do not spill fuel. If fuel is spilled, clean up before starting engine.
MOVING PARTS can cause injury.
Moving parts, such as fans, rotors, and belts can cut fingers and hands and catch loose clothing.
1.Keep all doors, panels, covers, and guards closed and securely in place.
2.Stop engine before installing or connecting unit.
3.Have only qualified people remove guards or covers for maintenance and troubleshooting as necessary.
4.To prevent accidental starting during servicing, disconnect negative (±) 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.
SPARKS can cause BATTERY GASES TO EXPLODE; BATTERY ACID can burn eyes and skin.
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.
Batteries contain acid and generate explosive gases.
4.Do not use welder to charge batteries or jump start vehicles.
5.Observe correct polarity (+ and ±) on batteries.
STEAM AND PRESSURIZED HOT COOLANT can burn face, eyes, and skin.
It is best to check coolant level when engine is cold to avoid scalding.
1.If the engine is warm and checking is needed, follow steps 2 and 3.
2.Wear safety glasses and gloves and put a rag over cap.
3.Turn cap slightly and let pressure escape slowly before completely removing cap.
