Warning messages appear throughout this manual to alert you to potentially
hazardous con di tions. Two designations indicate their relative seriousness:
Familiarize yourself with proper procedures and methods before you install,
operate or re pair the equipment to avoid personal injury or damage to the
equipment. If you train service peo ple or equip ment operators, it is important to
explain safety precautions to your students and en cour age safety awareness.
Personal Safety
Follow these precautions for your own safety:
• Treat every circuit like a gun that may be loaded. It may not be "live," but
be sure. Check with a neon tester or voltmeter, or simply unplug the ma-
chine.
• Know how to turn off the power in the work area and get help in an emer-
gen cy.
• Don't work on equipment under power unless it's absolutely necessary.
If you must, use extreme cau tion. Don't grasp two sides of a live circuit
at the same time—use one hand when reach ing into a cir cuit, touching
a ground ed case or chas sis with that wrist or el bow if pos si ble. This pre-
vents cur rent from passing through vital organs. Observe this rule when
con nect ing or dis con nect ing plugs or leads, or mak ing any adjustments
on a live cir cuit.
