DEATH ON CONTACT

may result if personnel fail to observe safety precautions.

When maintenance adjustments on this equipment are made with power ap-

plied, be careful when working near the interior of the equipment, or near the

power distributing wiring.

Never work on electronic equipment unless there is another person nearby

who is familiar with the operation and hazards of the equipment and who is

competent in administering first aid. When the technician is aided by operators,

he must warn them about dangerous areas.

Whenever possible, the power supply to the equipment must be shut off

before beginning maintenance work on the equipment. Take particular care to

ground every capacitor likely to hold a dangerous potential.

When working inside the equipment, after the power has been turned off,

always ground every part before touching it.

Be careful not to contact high-current connections when installing or operat-

ing this equipment.

Whenever the nature of the operation permits, keep one hand away from the

equipment to reduce the hazard of current flowing through vital organs of the

body.

Adequate ventilation should be provided while using TRICHLOROTRIF-

LUOROETHANE. Prolonged breathing of vapor should be avoided. The sol-

vent should not be used near heat or open flame; the products of decomposition

are toxic and irritating. Since TRICHLOROTRIFLUOROETHANE dissolves

natural oils, prolonged contact should be avoided. When necessary, use gloves

which the solvent cannot penetrate. If the solvent is taken internally, consult a

physician immediately.

Compressed air shall not be used for cleaning purposes except where reduced to

less than 29 pounds per square inch (psi) and then only with effective chip

guarding and personnel protective equipment. Do not use compressed air to dry

parts when TRICHLOROTRIFLUOROETHANE has been used. Compressed

air is dangerous and can cause serious bodily harm if protective means or

methods are not observed to prevent chips or particles (of whatever size) from

being blown into the eyes or unbroken skin of the operator or other personnel.

CAUTIONS

Proper grounding is essential to satisfactory operation of the converter.

This equipment is transistorized; observe all cautions to prevent transistor

damage. Do not make continuity or resistance checks other than those specified

in the tests. Damage to the transistors and microelectronic devices, which can

impair the performance of the equipment, may result if improper battery volt-

ages and polarities are applied.
