WARNING

Personnel performing operations, procedures, and practices which are included or implied in this

technical manual shall observe the following warnings. Disregard of these warnings and precaution-

ary information can cause serious injury, death, or destruction of material.

Ground the tester with the pigtail ground wire in the power inlet cable before using the tester.

Use trichloroethylene only in an adequately ventilated area. Avoid prolonged or repeated breath-

ing of vapor. Avoid prolonged or repeated contact with the skin.

Stop operation immediately if a defect is noted that could cause damage to the tester by con-

Detonate explosives from a safe distance. Keep blasting caps, detonating cords, and safety

fuses separated from the explosive charges until required for use.

Do not tow the tester behind a vehicle, use as a step, or place it under aircraft dump valve.
