1-4. Additional Symbols For Installation, Operation, And Maintenance

FALLING UNIT can cause injury.

DUse lifting eye to lift unit only, NOT running gear, gas cylinders, trailer, or any other accessories.

DUse equipment of adequate capacity to lift and support unit.

DIf using lift forks to move unit, be sure forks are long enough to extend beyond opposite side of unit.

FLYING SPARKS can cause injury.

D Wear a face shield to protect eyes and face.

D Shape tungsten electrode only on grinder with proper guards in a safe location wearing proper face, hand, and body protection.

DSparks can cause fires — keep flammables away.

OVERUSE can cause OVERHEATING.

DAllow cooling period; follow rated duty cycle.

DReduce current or reduce duty cycle before starting to weld again.

DDo not block or filter airflow to unit.

STATIC (ESD) can damage PC boards.

DPut on grounded wrist strap BEFORE handling boards or parts.

DUse proper static-proof bags and boxes to store, move, or ship PC boards.
