WELDING can cause fire or explosion.
Welding on closed containers, such as tanks, drums, or pipes, can cause them to blow up. Sparks can fly off from the welding arc. The flying sparks, hot workpiece, and hot equipment can cause fires and burns. Accidental contact of electrode to metal objects can cause sparks, explosion, overheating, or fire. Check and be sure the area is safe before doing any welding.
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.
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, drums, or pipes, unless they are properly prepared according to AWS F4.1 (see Safety Standards).
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
12.Remove any combustibles, such as a butane lighter or matches, from your person before doing any welding.
WARNING
ENGINES can be hazardous.
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.
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.
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.
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
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
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.
